Acoustic Emission Testing (AET) Services in Houston 2026 — Atlantis NDT

Atlantis NDT delivers Acoustic Emission Testing (AET) services in Houston. ASNT NDT Level III-led. AET demand around Houston comes mainly from oil & gas, petrochemical & refining. Technicians are certified by their employer to its SNT-TC-1A written practice, and procedures and reports are reviewed by an ASNT NDT Level III (UT, RT, MT, PT, VT). Where we work: nationwide. Technicians are mobilised to your site anywhere in the USA; apart from the Houston office there is no local office, so mobilisation is planned and quoted for each job.

AET Method Overview

Acoustic Emission Testing (AET) is an advanced NDT technique. Atlantis NDT Level III approves the Procedure + signs off final disposition. Calibration block + reference standards traceable to NIST/NPL/PTB. Per ASME Section V applicable Article + ASTM E-series + ISO 17635/17636/17640. Atlantis NDT integrates AET data into Digital Twin platform 3D defect overlay.

Code + Compliance in Houston

AET delivery aligns with: ASME B&PV V + VIII + IX; ASME B31 piping; API 510 + 570 + 571 + 579 + 580 + 581 + 653; ASTM E-series; ISO 17635/17636/17640; NACE MR0175/MR0103; AWS D1.1/3.6; IACS Rec-20. Records are kept in Atlantis NDT ERP.

How Acoustic Emission Testing (AE) works

Acoustic emission listens rather than interrogates. Sensors on the structure detect the transient elastic waves released when a defect grows, when a crack face rubs, or when a leak turbulently escapes, while the item is under a controlled stress or pressure. It is a global, real-time method: a small number of sensors monitor an entire vessel or tank rather than a single location.

What it detects

Active, growing defects during a controlled pressure or load test — the distinction between a flaw that is stable and one that is propagating
Tank floor corrosion activity and leakage on in-service aboveground storage tanks without taking them out of service
Crack growth in pressure vessels, spheres and reactors during hydrotest or over-pressure
Leakage in valves, heat exchangers and buried lines

What it will not do

AE locates and ranks activity; it does not size or characterise a defect. Every zone it flags requires follow-up by UT, radiography or visual examination to determine what is actually there. It is also sensitive to background noise, so test conditions and sensor coupling govern the quality of the result far more than in other methods.

When Acoustic Emission Testing (AE) is the right choice

Choose AE where the question is "is anything actively degrading right now, and where" across a large item, particularly where taking it out of service for internal inspection is the expensive alternative.

Codes and acceptance criteria

Examinations are performed to written procedures qualified against ASME Section V Article 11 and Article 12, ASTM E569, ASTM E1930 for pressure vessel examination, ASTM E1067 for fibre-reinforced vessels, and API 653 Annex E practice for tank floor evaluation. Acceptance criteria come from the construction or in-service code governing the item — ASME Section VIII for pressure vessels, ASME B31.3 for process piping, API 510, API 570 and API 653 in service, AWS D1.1 for structural steel — and the applicable edition is recorded against the examination so the disposition can be reconstructed later.

Houston context

Houston is the global capital of the oil and gas industry, hosting the largest concentration of US refining and petrochemical capacity, with refineries, petrochemical complexes and midstream facilities across the Greater Houston area. The sheer density of pressure vessels, heat exchangers, storage tanks, and pipeline networks makes digital twin technology an operational necessity for integrity managers working across Shell, ExxonMobil, Chevron, and Lyondell Basell assets. The humid subtropical climate and proximity to the Gulf of Mexico create persistent corrosion challenges, making real-time thickness trending within a 3D digital twin a critical risk-management tool.

How the examination is controlled

Agree personnel qualification, equipment checks, procedure revision and review responsibilities for the examination. Retain those records with the results and coverage limitations.

What you receive

A report in your required format, with indications located against the component and, where relevant, against a persistent corrosion monitoring location so trends stay continuous between campaigns
Raw data files in the instrument-native format plus an open export, so the dataset outlives any single supplier relationship
The procedure revision, technician certification state and instrument calibration status applicable at the time of examination
Where a finding affects continued service, a clear statement of the code clause that governs the acceptance decision
