Refinery & Petrochemical NDT Inspection
Turnarounds and shutdowns run on a fixed clock, and inspection can't be the reason a unit misses restart. Prime Inspections delivers certified non-destructive testing for refinery and petrochemical process piping, pressure vessels, and structural systems — planned work and emergency call-outs alike.
Our Level II and Level III technicians bring RT, PAUT, AUT, TOFD, MT, and PT to live and shutdown units, producing documented, code-compliant reports that turnaround planners and inspection departments can act on immediately.
- Turnarounds & Shutdowns
- Process Piping Specialists
What we inspect
Certified Level II and Level III technicians, methods matched to the unit and the governing code.
Process Piping
RT, PAUT, and TOFD weld inspection on process piping circuits, matched to ASME B31.3 new construction or API 570 in-service acceptance.
Pressure Vessels & Reactors
UT, PAUT, and RT on pressure vessel welds, nozzles, and internals during fabrication, turnaround, and repair inspection.
Storage Tanks
Floor and shell UT thickness surveys, MT, and welded-seam inspection supporting API 653 tank inspection programs.
Structural & Piping Supports
MT and PT on structural steel, pipe racks, and supports subject to vibration and thermal cycling in process units.
Why refinery & petrochemical planners choose Prime
Built for the turnaround clock
Digital radiography and AUT cut per-weld turnaround so inspection results feed the unit's restart timeline instead of holding it up.
Code-compliant reporting
Every weld and component reported against the governing code — API 570, API 653, or ASME B31.3 — ready for the inspection department's file.
Certified crews
Level II technicians certified to our written practice under ASNT SNT-TC-1A / ANSI/ASNT CP-189, with ASNT Level III oversight and AWS CWI support where the specification calls for it, experienced on live and shutdown process units.
24/7 nationwide response
Coverage from our offices in Katy and Lubbock, Texas plus field locations nationwide, with 24/7 emergency call-out when an outage can't wait for the next planned window.

Frequently asked questions
What codes apply to refinery and petrochemical inspection?
In-service piping and equipment inspection typically follows API 570 (piping) and API 653 (aboveground storage tanks); new construction piping follows ASME B31.3. We inspect and report to the code named in your turnaround scope.
Can you support a turnaround or shutdown on a compressed schedule?
Yes — Prime mobilizes crews for planned turnarounds and shutdowns with 24/7 coverage to keep inspection off the schedule's critical path.
What methods do you use on process piping and pressure vessels?
RT, PAUT, AUT, TOFD, MT, and PT, matched to wall thickness, material, and the access constraints typical of live refinery and petrochemical units.
