Atlantis NDT delivers professional Liquid Penetrant Testing (PT) inspection services in Houston from ASNT NDT Level II + III certified inspectors. Specialising in surface-breaking defect detection in welds, castings and machined parts. PT demand around Houston comes mainly from oil & gas, petrochemical & refining.

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.

Penetrant testing in Houston: what the work actually is
Houston is the densest NDT services market in North America — the ship channel refineries and chemical complexes from Pasadena to Baytown, the upstream and midstream head offices that buy inspection nationally, and a fabrication belt building pressure vessels and offshore modules.
PT carries the non-magnetic work the channel generates in volume: austenitic overlay and cladding checks, stainless and alloy piping welds, and machined components, with high-sensitivity systems on hydrogen-service equipment.
What governs acceptance here
API 510, 570 and 653 govern in-service inspection of vessels, piping and tanks; ASME Section V supplies the methods and Section VIII and B31.3 the acceptance; operator contractor-approval gates site access on top of SNT-TC-1A certification. An examination that is technically sound but performed outside the governing regime is not an examination anyone will accept — which is why the code family matters as much as the technique in Houston.
How Atlantis delivers PT in Houston
Teams are mobilised to your site under Atlantis procedures with ASNT Level III oversight — we do not claim a depot or laboratory in Houston, and say so plainly. What you receive is the examination performed to a qualified procedure, findings evaluated against the acceptance criteria your contract names, and records structured to survive a client audit years later.

Houston scopes are quoted from the national penetrant testing service: visible and fluorescent penetrant examination on stainless, nickel alloy, aluminium and other non-magnetic material.
