Key points covered

API 570 inspector services support owner-operators in maintaining safe, code-compliant in-service piping under the API 570 Piping Inspection Code (3rd Edition 2022). Scope covers visual + NDT inspection of process piping, corrosion monitoring location (CML) tracking, RBI program design per API 581, fitness-for-service evaluation per API 579-1/ASME FFS-1, repair / re-rating recommendations and code-defensible inspection-interval setting.
Refineries, petrochemical complexes, gas processing plants, chemical manufacturing, LNG terminals, midstream gathering systems. Real client list spans US Gulf Coast, GCC (Aramco, ADNOC, QatarEnergy contractor sites), India (IOCL, BPCL, HPCL, Reliance Jamnagar) and Southeast Asia (PETRONAS, Pertamina, PTT).
API 570 3rd Edition 2022 (with all addenda), API 574 (inspection practices for piping system components), API 578 (material verification), API 580 / 581 (RBI), API 579-1/ASME FFS-1 2021 (FFS), ASME B31.3 Process Piping, ASME B31.4 Liquid Pipelines, ASME B31.8 Gas Pipelines, ASME Section V (NDE), NACE MR0175 / ISO 15156 (sour service), NACE SP0102 (CUI).
Standard scope-of-work to first site visit is 5-10 business days. Emergency engagements (urgent FFS argument, unplanned leak investigation, audit defence) we have closed inside 48 hours. We field API 570 Authorized Inspectors with current API ICP credentials and ASNT Level III NDT support.
Yes. CUI program design is a core service line. Approach: damage-mechanism review per API 571, susceptibility mapping per API 583 / NACE SP0198, inspection technique selection (RT pulsed eddy current, neutron backscatter, profile RT, on-stream insulation removal), CML placement and interval setting. Real outcomes include 40-60% reduction in unplanned-shutdown piping failures within 24 months.
Yes. For owner-operators without a full-time API 570 Authorized Inspector, we provide an outsourced inspector-of-record model — named API 570 Authorized Inspector signs the inspection records, attends turnaround inspections, defends the program at insurer / regulator audit. Engagement is documented in your written inspection program per API 570 §6.
When a piping defect is found that exceeds simple acceptance criteria, FFS per API 579-1/ASME FFS-1 evaluates whether the equipment is still safe for continued service. Levels: Level 1 (screening, conservative), Level 2 (detailed engineering analysis), Level 3 (advanced — FEA / fracture mechanics). Outcome: signed FFS report defending continued service for X more years, rerate, repair, or replace decision.
Yes. We attend insurer audits (Aon, Marsh McLennan, AXA XL inspections), state boiler-and-pressure-vessel inspector visits, EPA / TCEQ / DEQ audits, OSHA PSM RCA support. Pre-audit gap closure, on-site audit attendance, NCR response and corrective-action close-out.
