Industries/Chemical Plants
Chemical Plant NDT Inspection The methods, the codes and the crews we bring to process piping, vessels and tanks.
Chemical plants run the same inspection problem as the refineries next door: process piping circuits, pressure vessels and reactors, exchangers, storage tanks and the structural steel holding it all up — inspected on a turnaround clock, against ASME B31.3, API 570 and API 653.
That is work Prime Inspections is built for: Level II and Level III technicians, the full method range on one mobilization, and digital radiography that does not add 45 minutes of darkroom to every exposure.

- Vessels & reactors
- Exchangers

What we would inspect
Tell us the circuit and the code, and we will tell you which method answers it.
Process piping circuits
RT, PAUT and TOFD weld inspection on process piping, matched to ASME B31.3 new construction or API 570 in-service acceptance, with UT wall-thickness surveys on operating circuits.
Pressure vessels, reactors & exchangers
UT, PAUT and RT on pressure vessel welds, nozzles and internals during fabrication, turnaround and repair inspection, and on shell-and-tube exchanger welds.
Storage tanks
Floor and shell UT thickness surveys, MT, and welded-seam inspection supporting API 653 tank inspection programs.
Structural steel & pipe supports
MT and PT on structural steel, pipe racks and supports subject to vibration and thermal cycling in process units.
Positive material identification (PMI)
XRF and OES alloy verification on process piping, fittings and components, to confirm the material in the line is the alloy the drawing and the specification call for.
What we would bring
Built for the turnaround clock
Turnarounds, maintenance shutdowns and emergency outages are what our crews are built and scaled for — large crew mobilization, 24/7 coverage, real-time reporting, and repairs identified while the crew is still at the joint.
Corrosion mapping, not guesswork
Encoded phased-array corrosion mapping measures and positions remaining wall thickness and pit depth and records a C-scan map for your program. We supply the data; the fitness-for-service decision stays with your inspection department.
One crew, every method
RT, digital radiography, CR, RTR, PAUT, AUT, TOFD, UT, MT, PT and VT from the same mobilization and the same written practice, reported in one format.
Codes of record
In-service piping and equipment inspection typically follows API 570 (piping) and API 653 (aboveground storage tanks); new construction piping follows ASME B31.3 and pressure vessels follow ASME Section VIII. Examination requirements come from ASME Section V; the acceptance criteria are whatever your project specification names.

Frequently asked questions
Does Prime work in chemical plants?
The methods, the codes and the crews are the same ones we bring to refinery and petrochemical work — process piping circuits, pressure vessels and reactors, exchangers, storage tanks and structural steel. Ask us what we have done in your sector and we will tell you straight rather than imply a record on a web page.
Which methods would you use?
RT, digital radiography (DR), computed radiography (CR) and real-time radiography (RTR), PAUT, AUT and TOFD, the conventional methods — MT, PT, UT and VT — and positive material identification (PMI).
Can you do positive material identification?
Yes. We run PMI by XRF and OES to verify alloy on process piping, fittings and components, and report each reading against the material the specification calls for.
What codes apply?
API 570 for in-service piping and API 653 for aboveground storage tanks; ASME B31.3 for new construction piping and ASME Section VIII for pressure vessels — as your specification calls out.
Can you support a turnaround on a compressed schedule?
Yes. Turnarounds, maintenance shutdowns and emergency outages are core work: large crew mobilization, 24/7 coverage and real-time reporting so inspection stays off the critical path.
Do you employ API 510, 570 or 653 certified inspectors?
No. Prime performs and reports the nondestructive examination in support of your inspection program. The certified-inspector role, the evaluation and the fitness-for-service decision stay with the owner and their engineering.
Do you do corrosion mapping?
Yes — encoded phased-array corrosion mapping with remaining wall thickness and pit depth measured, positioned and recorded, and a C-scan map documented for your program.
