API 570 Piping Inspection Support in New Jersey
Short answer: In New Jersey, API 570 inspection of refinery, terminal, chemical and pharmaceutical piping is directed, evaluated and signed by the owner's API 570 Authorized Inspector (AI). Atlantis NDT performs the nondestructive examinations the AI's plan calls for: UT thickness at condition monitoring locations (CMLs), automated corrosion mapping, profile radiography, guided-wave screening, CUI follow-up and PAUT or TOFD on welds. Atlantis performs the NDE; your API 570 Authorized Inspector remains inspector of record and signs the inspection report.
New Jersey's piping is packed into some of the most congested industrial ground in the country. Two refineries, a near-continuous band of terminals along the Arthur Kill and the Kill van Kull, the pipeline hub at Linden that feeds New York Harbor, and a large chemical and pharmaceutical base all sit close to homes, highways and water. That proximity explains the state's regulatory character: on top of federal OSHA process safety management, New Jersey runs its own Toxic Catastrophe Prevention Act programme for extraordinarily hazardous substances, and NJDEP's discharge prevention rules shape how terminals document their equipment. This hub explains where API 570 piping is in New Jersey, how the code frames the work, which NDE methods suit harbor and Delaware River sites, how state and federal rules divide the plant from the pipeline, and what Atlantis delivers to your AI. To start, request an NDE scope for your AI's inspection plan.
Where API 570 piping is in New Jersey
Direct answer: New Jersey process piping is concentrated at the Bayway refinery in Linden and the Paulsboro refinery on the Delaware, at harbor terminals from Bayonne to Perth Amboy, at the Linden pipeline hub, at chemical plants along the Delaware River and the Raritan corridor, at pharmaceutical and specialty-chemical sites in central New Jersey, and at gas-fired power and utility plants.
Linden, Bayway and the Arthur Kill
Phillips 66's Bayway refinery in Linden is the largest single piping population in northern New Jersey: crude and vacuum transfer lines, FCC and alkylation piping, hydrotreating effluent systems, sour water and amine circuits, hydrogen and fuel-gas headers, and the rack runs that tie units to tankage, docks and the pipelines. Around it, Linden is a delivery point for major products pipelines serving New York Harbor, and terminals in Carteret, Woodbridge's Sewaren and Port Reading sections and Perth Amboy, several on former refinery land, hold manifold, pump and transfer piping that has been modified many times. Old refinery sites converted to terminals often carry piping whose original construction records are incomplete, which makes baseline thickness surveys and material identification a common first step before any rate can be trusted.
Bayonne, Jersey City, Newark and Elizabeth
Bayonne's large bulk-liquid terminal, Jersey City's terminals and the Newark and Elizabeth port area move petroleum products, chemicals, vegetable oils and jet fuel. Terminal piping here is mostly Class 3 in API 570 terms, with heated and insulated lines for heavy products and stainless or lined piping in chemical service. Much of the ground is reclaimed marsh, so buried and partially buried lines, pipe in sleeves under roads and rail spurs, and soil-to-air interfaces are routine CML locations.
Paulsboro and the Delaware River corridor
PBF Energy's Paulsboro refinery in Gloucester County anchors the southern cluster, with terminals at Paulsboro, Westville and Pennsauken and chemical plants downriver toward Salem County, including the Deepwater chemical complex near the Delaware Memorial Bridge. Crude and products move by ship and barge, so dock lines, river-terrace buried piping and long rack runs are a large share of the inspection list. Chemical plants add services where internal corrosion, not just external, drives CML density: acids, chlorinated compounds and caustic.
Central New Jersey chemical and pharmaceutical plants
The Route 1, Raritan and Route 287 corridors hold pharmaceutical, specialty-chemical, flavour and fragrance, and coatings plants. Their piping is often austenitic stainless steel, lined pipe or alloys, operating at modest temperatures but carrying flammable solvents or toxic intermediates. Owners frequently adopt API 570 principles for those services, with RP 574 practices, even though the plants are not refineries. Chloride stress corrosion cracking of stainless under wet insulation and pitting at supports are characteristic findings in this coastal climate.
Utilities and power
Gas-fired power stations, cogeneration plants and utility facilities across the state run ASME B31.1 and B31.3 piping, ammonia for emissions control, and fuel-gas systems. Natural gas transmission and distribution lines belong to the pipeline regulators, and nuclear plant piping at the Salem and Hope Creek site follows nuclear in-service rules; both are outside this page.
What API 570 requires, in plain terms
Direct answer: API 570 governs in-service inspection, repair, alteration and rerating of metallic process piping and its pressure-relief devices. Piping is grouped into circuits, classified by the consequence of a leak, monitored at CMLs placed where damage is expected, and inspected at intervals set by class and remaining life or by a qualifying RBI programme. The AI evaluates the results and signs.
The current edition is the fifth, published in February 2024 together with a reissued API RP 574. API describes the main changes as a defined Inspection Supervisor role, strengthened pressure-relieving device requirements and new rules on deferring inspection repair recommendations. Please work from a licensed current copy; free versions online are usually decades old. In our words, the parts of the code that shape an NDE scope are:
- Who does what. API 570 assumes the owner has, or can engage, an authorized inspection agency, a repair organisation, and qualified piping engineers, inspectors and examiners. The authorized piping inspector evaluates; examiners such as our technicians measure and record.
- Scope. Hydrocarbon, chemical and other flammable or toxic process services are covered; low-hazard utility services are optional. For new piping before service, ASME B31.3 governs, not API 570.
- Service classes. Class 1 covers services where a leak could quickly escalate, such as auto-refrigerating flammables and rapidly vaporising light hydrocarbons; the 1998 edition also listed piping over water and public throughways, which describes a lot of harbor piping. Class 2 covers most unit piping, Class 3 most off-site and product lines, and later editions added a Class 4 for low-consequence services.
- Intervals. Thickness readings are due at the shorter of half the remaining life or the class maximum. Industry summaries of current editions list five years for Class 1 thickness and external visual, ten and five for Class 2, and ten and ten for Class 3, with Class 4 at the owner's discretion; the 1998 edition used the same Class 1 to 3 values. Confirm current values in the licensed edition with your AI.
- Special locations. Injection points, mix points, deadlegs, small-bore connections, insulated lines and soil-to-air interfaces get extra CMLs and, in some cases, their own circuits.
- Rates, repairs and rerating. Long-term and short-term corrosion rates come from CML history and the governing rate sets remaining life; the inspector authorises repairs, and the piping engineer is involved in alterations and rerates.
Atlantis can calculate corrosion rates and remaining life from its thickness data for the AI's review; setting the interval is the AI's and owner's decision under the code and the rules that apply. Background: API 570 code requirements, what triggers an internal piping inspection and API 510 vs API 570.
Salt air, old piping and toxic service: the New Jersey damage picture
Direct answer: New Jersey programmes combine coastal external corrosion and CUI, the internal mechanisms of two refineries, chloride cracking of stainless in chemical and pharmaceutical plants, and the integrity questions that come with converted, decades-old terminal piping. Toxic services under the state's TCPA programme raise the consequence side of every decision.
External corrosion and CUI. Salt-laden air, freeze-thaw cycles and long wet periods attack coatings at supports, clamps and insulation penetrations. Carbon steel in the CUI temperature range and stainless steel at temperatures where chloride cracking can develop both need targeted follow-up. The 1998 edition of API 570 gave target follow-up percentages for damaged and suspect insulation by class; check the current edition and API RP 583 for the approach your AI applies.
Refinery mechanisms. At Bayway and Paulsboro, typical API RP 571 lists include sulfidation in hot circuits, ammonium salt and chloride corrosion in hydroprocessing effluent and overhead systems, wet H2S damage in sour water and amine service, and acid corrosion where alkylation units operate. Injection and mix points need grid scanning rather than spot readings.
Converted and congested terminals. Terminal piping that has changed service, been rerouted or inherited from a former refinery often lacks reliable nominal thicknesses and drawings. A baseline survey with material verification, followed by a short initial interval to establish a rate, gives the AI a defensible starting point.
Flood and storm damage. Superstorm Sandy in 2012 showed how surge water can reach piping, supports and insulation along the Arthur Kill. After significant flooding, AIs commonly call for external walkdowns and targeted NDE on wetted insulation and buried transitions.
NDE methods for API 570 work in New Jersey
Direct answer: UT thickness at CMLs is the backbone; corrosion mapping covers injection points and support areas; profile RT handles insulated and small-bore lines and is often preferred in congested plants when exclusion zones can be managed; guided-wave screening covers sleeved crossings and long rack runs; PAUT, TOFD, PT and MT cover welds and cracking.
| Method | What it finds | Typical New Jersey application | Governing reference |
|---|---|---|---|
| UT thickness at CMLs | General wall loss; rate and remaining-life data | Unit piping at Bayway and Paulsboro; baseline surveys on converted terminal piping | API 570; API RP 574; ASME Section V |
| Automated corrosion mapping | Localised thinning, pitting and erosion maps | Overhead and effluent injection points; support contact areas on harbor rack lines | API 570; API RP 571 |
| Profile RT | Wall loss and deposits through insulation; small-bore condition | Heated heavy-product lines at Bayonne and the Arthur Kill; deadlegs and drains | API 570; ASME Section V Article 2 |
| Guided-wave screening | Metal-loss locations along runs (screening, then UT) | Pipe in sleeves under the Turnpike, roads and rail spurs; dock lines on the Delaware | API 570; ASTM E2775 |
| PAUT and TOFD | Planar flaws and cracking at welds, with sizing | Amine and sour water welds; repair and tie-in welds at turnarounds | ASME Section V Article 4 |
| PT and MT | Surface-breaking cracks | Chloride cracking checks on stainless piping in pharmaceutical and chemical plants; socket welds | ASME Section V Articles 6 and 7 |
| VT | Coating, insulation, supports, leaks, vibration | Every external inspection; post-storm and post-flood walkdowns | API 570; API RP 574 |
| CUI screening support | Wall loss under insulation | Insulated carbon steel in the CUI range across coastal sites | API 570; API RP 583 |
New Jersey became an NRC Agreement State in 2009, and NJDEP's radiation protection programme licenses radioactive materials used in industrial radiography. RT on New Jersey sites is performed only by crews licensed for that work in New Jersey, and in tightly packed terminals we plan exclusion zones with the site during scoping, or propose a non-radiographic alternative where the AI accepts it. Method selection follows the circuit's damage mechanisms; see our API 571 damage mechanisms guide.
How Atlantis supports your Authorized Inspector
Direct answer: We carry out the NDE in the AI's plan and hand back structured, traceable data: Level III-reviewed procedures, ASNT SNT-TC-1A certified technicians, on-site comparison with history, and a digital report by circuit and CML. We are not an Authorized Inspection Agency and we do not supply API-certified inspectors.
- Scope from the plan. Circuits, isometrics, CMLs, damage mechanisms, methods and coverage come from the AI's plan, including any items raised in TCPA or PSM audits.
- Procedures. An ASNT NDT Level III prepares or reviews each technique for the owner's specification: UT on stainless and lined pipe, profile RT on insulated lines, PT on stainless where chloride cracking is suspected.
- Fieldwork. Crews are mobilised to your site; the schedule is agreed during scoping around permits, unit status, marine traffic and terminal throughput.
- Data QA. Readings are checked against calibration records and previous surveys before the crew leaves; anomalies and inaccessible CMLs are re-shot or flagged.
- Report. CML readings, C-scans, radiographs, screening results with follow-up, calibration records and technician certifications, delivered in our digital reporting platform.
- AI evaluation and sign-off. The AI assesses rates, remaining life and next dates, decides on repairs and signs.
- Next interval. CML identifiers and reading patterns carry forward unchanged.
Because New Jersey record-keeping expectations are long, under TCPA mechanical-integrity records are kept for the life of the equipment, consistent data structure is worth as much as the readings themselves. Risk-based inspection and fitness-for-service assessments are carried out by the owner's engineers or a specialist using our data; Atlantis does not offer them.

New Jersey regulations that sit on top of API 570
Direct answer: No New Jersey statute sets API 570 intervals. Federal OSHA's PSM rule (29 CFR 1910.119(j)) applies to covered processes, with API 570 as the usual good practice, and NJDEP's Toxic Catastrophe Prevention Act rules at N.J.A.C. 7:31 add a state mechanical-integrity programme for extraordinarily hazardous substances. The BPU regulates intrastate gas pipelines; PHMSA regulates hazardous-liquid lines. Confirm current requirements with each agency.
Federal OSHA process safety management
New Jersey's state occupational safety plan (PEOSH) covers public employees only, so refineries, terminals and chemical plants are under federal OSHA. The PSM mechanical-integrity element covers piping systems and their components, relief and vent systems: written procedures, inspection and testing following recognised and generally accepted good engineering practice, frequencies consistent with that practice and with operating experience, documented results including the date, the person who performed the work, the equipment identifier and the results, and correction of deficiencies. API 570 is the practice most New Jersey owners cite. EPA's Risk Management Program (40 CFR Part 68) mirrors the element for Program 3 processes.
NJDEP Toxic Catastrophe Prevention Act, N.J.A.C. 7:31
New Jersey adopted the Toxic Catastrophe Prevention Act in 1985, after the Bhopal disaster, to protect the public beyond the fence line from catastrophic releases of extraordinarily hazardous substances (EHS). NJDEP's Bureau of Release Prevention administers the programme, which integrates the federal RMP rule with additional state requirements. The rules define mechanical integrity as ensuring that process equipment is made of proper materials and properly installed, maintained and replaced to prevent failures and releases, and they require a mechanical integrity and preventive maintenance programme, at N.J.A.C. 7:31-4.5, with records kept for the lifetime of the EHS equipment. For piping in an EHS process, that means the API 570 programme is part of what NJDEP reviews, and the inspection and NDE history has to stay retrievable for as long as the piping exists. Confirm which of your processes are covered and the current rule text with the Bureau of Release Prevention.
NJDEP discharge prevention, N.J.A.C. 7:1E
Major facilities under the Spill Compensation and Control Act keep Discharge Prevention, Containment and Countermeasure (DPCC) plans. The rules are best known for their tank-testing requirements, covered in our companion API 653 tank inspection hub for New Jersey, but the plan covers the facility's transfer and process areas too, and many terminals reference their piping inspection programme in it. Check what your DPCC plan commits you to before the inspection schedule is fixed.
Pipelines: BPU, PHMSA and the plant fence
The New Jersey Board of Public Utilities inspects intrastate natural gas pipelines under PHMSA certification. Hazardous-liquid pipeline safety in New Jersey is enforced directly by PHMSA, which covers the products pipelines into Linden and the crude and products lines serving the refineries. The federal hazardous-liquid rule (49 CFR Part 195) excludes in-plant piping at refineries and certain terminal transfer piping, so piping inside the fence stays under API 570, PSM and TCPA, while the regulated pipeline follows Part 195 and gas lines follow Part 192. In the Linden hub, where pipelines, terminals and the refinery meet, operators document the boundary at launchers, receivers, meter stations and block valves. Pipeline-side NDE is on our pipeline inspection page.
Boilers and pressure vessels
The New Jersey Department of Labor and Workforce Development's boiler, pressure vessel and refrigeration programme covers boilers and pressure vessels, not process piping. Vessel and piping work often share outages, so see the companion API 510 pressure vessel inspection hub for New Jersey.
Planning around throughput, storms and winter
Direct answer: Run on-stream CML surveys, mapping and screening year-round, keep insulation removal to the warmer months, book refinery turnaround NDE early, and plan terminal work around product seasons and hurricane season.
- Product seasons. Harbor terminals switch gasoline grades and build heating-oil inventory before winter, so manifold and transfer-line work goes more smoothly in the shoulder months.
- Hurricane season and nor'easters. Avoid leaving insulation open into the stormy months, and plan post-event walkdowns into the contract so they can start quickly.
- Winter. Cold-weather UT works with suitable couplant and temperature correction, but stripping insulation in freezing weather invites new CUI; schedule it for spring to autumn where the AI allows.
- Turnarounds. PAUT or TOFD on repair and tie-in welds, profile RT on small-bore, internal visual where lines are open, and baselines on replacement spools.
- Congestion. Hot-work permits, RT exclusion zones, crane and scaffold access and road closures take longer on harbor sites; agree laydown and access early.
API 570 piping inspection support across New Jersey
Direct answer: Atlantis supports API 570 programmes statewide, from Bayonne and Linden to Paulsboro and Salem County. Crews are mobilised to your site and the schedule is agreed during scoping.
- North Jersey harbor: Bayonne, Jersey City, Newark and Elizabeth terminals, port and airport fuel piping.
- Arthur Kill: Linden and the Bayway refinery, Carteret, Sewaren, Port Reading and Perth Amboy terminals and the Linden pipeline hub.
- Central New Jersey: pharmaceutical, specialty-chemical and utility piping along the Route 1, Raritan and Route 287 corridors.
- South Jersey and the Delaware: the Paulsboro refinery, river terminals and chemical plants in Gloucester, Camden and Salem counties.
Statewide services are on NDT inspection services in New Jersey, Level III procedure and written-practice support is on NDT consulting in New Jersey, and technician skills are covered on ASNT NDT training in New Jersey.
Keeping piping history usable for the life of the equipment
Direct answer: We keep your circuit and CML numbering, record the reading pattern, instrument and calibration for each CML, and deliver data that loads into your inspection database, so rates stay valid and lifetime TCPA records stay coherent. Optional digital twin and ERP views are available.
New Jersey terminals and plants have changed hands repeatedly, and their inspection databases hold readings from many contractors. When a reading pattern or location does not match history, we flag it rather than let it distort a rate. New CMLs added by the AI are photographed and described so the next crew finds them. Results can be shown in a digital twin of the terminal or unit, and certificates, calibrations and work orders can be tracked in our inspection-management ERP. See sample layouts on NDT report templates and construction-code background in ASME B31.3 explained.

Frequently asked questions: API 570 in New Jersey
Who does API 570 piping inspection in New Jersey?
The owner's API 570 Authorized Piping Inspector, employed by the owner or an inspection agency, directs and signs the inspection. Qualified NDE examiners take the measurements. Atlantis performs the NDE and delivers documented results to your AI, who remains inspector of record.
Is API 570 required by law in New Jersey?
No New Jersey statute names API 570. Federal PSM requires piping inspection following recognised good engineering practice, usually API 570, and TCPA requires a mechanical-integrity programme for EHS processes. Confirm obligations with OSHA and NJDEP's Bureau of Release Prevention.
What does the TCPA mean for piping inspection records?
N.J.A.C. 7:31 requires a mechanical integrity and preventive maintenance programme for covered processes, with records kept for the lifetime of the EHS equipment. Your thickness history and NDE reports need to stay retrievable for as long as the piping is in service.
How often does refinery piping need inspection under API 570?
Thickness at the shorter of half the remaining life or the class maximum, and external visual by class, unless a qualifying RBI programme applies. The 1998 edition gave five years for Class 1 thickness; confirm current values with your AI.
Who regulates pipelines in New Jersey?
The BPU inspects intrastate gas pipelines; PHMSA enforces hazardous-liquid pipeline safety directly. In-plant refinery piping and certain terminal transfer piping are excluded from the federal liquids rule and stay under API 570.
Do you inspect stainless steel piping for chloride cracking?
Yes, as the AI specifies: visual examination after insulation removal, PT on suspect areas and volumetric methods where needed. The AI decides extent and evaluates the findings.
Can piping be inspected while the terminal keeps operating?
Yes. CML surveys, mapping, guided-wave screening, profile RT and external VT are normally done on-stream, scheduled around transfers and product moves.
Is Atlantis an Authorized Inspector?
No. We are not an Authorized Inspection Agency and we do not supply API-certified inspectors. We supply independent NDE data to the AI who signs.
Who licenses industrial radiography in New Jersey?
NJDEP's radiation protection programme, since New Jersey became an NRC Agreement State in 2009. RT is performed only by crews licensed in New Jersey.
What certifications do your NDE technicians hold?
ASNT SNT-TC-1A certification under our written practice, with ASNT NDT Level III oversight; certificates and calibration records accompany every report.
Do you offer RBI, fitness-for-service or API 570 training?
No. The owner's engineers or specialists perform RBI and FFS using our data, and we train only to ASNT SNT-TC-1A. See the API inspector career guide or ASNT Level III training.
How fast can you mobilise to Linden or Paulsboro?
We quote within 24 hours of receiving scope information; mobilisation is agreed during scoping around permits, unit schedules and terminal operations.
Next step
For CMLs coming due, a baseline on converted terminal piping, CUI follow-up or turnaround NDE, get a quote within 24 hours or book a scoping call. Atlantis performs the NDE; your API 570 Authorized Inspector remains inspector of record and signs the inspection report.
