Industries/Pipeline NDT Inspection
Pipeline NDT & Weld Inspection Services
Cross-country transmission, gathering, and distribution pipelines live or die on the quality of the girth weld. Prime Inspections delivers certified non-destructive testing for new construction, tie-ins, and in-service integrity programs — keeping pace with the spread while producing documented, code-compliant results.
Our Level II and Level III technicians bring pipeline-grade radiography, phased array and automated ultrasonics, and digital imaging to the ditch — helping operators, EPCs, and pipe fabricators move fast without cutting a corner on weld quality.

What we inspect
Certified Level II and Level III technicians, methods matched to the weld, the material, and the governing code.
Girth Welds & Tie-Ins
RT, digital radiography, and AUT/PAUT on mainline girth welds, tie-ins, and station piping — the highest-consequence weld on any pipeline project.
New Construction & Spread Work
Field radiography and automated ultrasonic scanning that keep pace with pipe going into the ditch, delivering same-shift results the construction crew can act on.
In-Service Integrity
UT wall-thickness surveys, PAUT, and MT/PT on operating pipeline systems, valve assemblies, and station piping supporting integrity management programs.
Pump & Compressor Station Piping
RT, PAUT, and TOFD on station piping, manifolds, and pressure-containing components at pump and compressor stations.
Why pipeline operators and EPCs choose Prime
Keeps pace with the spread
Digital radiography and AUT cut turnaround per weld so inspection keeps pace with the crew instead of becoming the bottleneck.
Audit-ready documentation
Every weld is reported against the governing code — API 1104 for construction, ASME B31.4/B31.8 for in-service — ready for the pipeline's quality 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, with deep field experience on cross-country pipeline projects.
Built for the field
24/7 emergency response from offices in Katy and Lubbock, Texas plus field locations nationwide — we mobilize on the spread's schedule, not ours.

Frequently asked questions
What codes govern pipeline weld inspection?
New construction pipeline welds are typically inspected to API 1104; in-service pipeline integrity work follows ASME B31.4 (liquids) or B31.8 (gas) and applicable DOT/PHMSA regulations. We inspect and report to the code specified in your project spec.
Do you inspect girth welds on cross-country pipeline construction?
Yes — radiographic testing (RT/DR) and phased array UT on girth welds during mainline construction, tie-ins, and station piping, with same-shift results using digital imaging.
Can you mobilize for spread crews across multiple states?
Yes. Prime provides 24/7 nationwide coverage with crews mobilized to keep pace with pipeline spread schedules.
