Conventional NDT
Conventional NDT is the foundation of SIS field and shop inspection. Our crews perform radiographic testing (film, CR, and DR), penetrant and magnetic particle examination, ultrasonic thickness testing, and visual testing with procedures your engineers and regulators expect.
Conventional NDT at Superior Integrity Services covers radiographic testing (film, CR, and DR), penetrant, magnetic particle, ultrasonic, and visual testing for welds and components in shop and field. Examinations follow written procedures aligned to API 1104 and ASME Section V, performed by ASNT SNT-TC-1A certified technicians working from 8 offices across TX, NM, OK, and ND.

Conventional NDT at SIS
Every conventional method we offer is backed by ASNT-certified technicians, written procedures aligned to ASME Section V and API 1104, and reporting your integrity team can disposition without chasing follow-up.
Radiographic testing — film, computed radiography (CR), and digital radiography (DR) — produces permanent or digital records of weld and component integrity. Penetrant and magnetic particle testing detect surface-breaking defects. Ultrasonic testing measures thickness and maps corrosion. Visual testing confirms fit-up and surface condition. Vacuum box leak detection lives under Mechanical Integrity.
For high-throughput pipeline construction requiring real-time radiography, automated ultrasonic testing, or X-ray crawlers, see our High-Capacity Pipeline NDT service line.
Common questions
Conventional NDT FAQs
What NDT methods does SIS use for weld inspection?
SIS performs radiographic testing (conventional film, computed radiography, and digital radiography), penetrant testing, magnetic particle testing, ultrasonic thickness testing, and visual testing — all to written procedures aligned to API 1104 and ASME Section V.
What is the difference between film RT, computed radiography, and digital radiography?
Conventional film RT uses gamma or X-ray sources with mobile darkroom processing to produce permanent film records. Computed radiography (CR) uses reusable imaging plates with digital image archives and field-flexible exposure setups. Digital radiography (DR) uses direct digital detector panels for immediate image review and electronic record retention.
What standards govern SIS conventional NDT work?
Conventional NDT examinations are performed to API 1104, ASME Section V, and AWS D1.1 acceptance standards, by technicians certified under ASNT SNT-TC-1A.
What reports do I receive after a conventional NDT inspection?
Each scope ships with method-specific inspection reports, radiographic images and weld maps, thickness and corrosion mapping data, and disposition-ready documentation packages your integrity team can act on.
Can SIS handle high-volume pipeline construction radiography?
Yes. For high-throughput pipeline construction requiring real-time radiography, automated ultrasonic testing, or X-ray crawlers, SIS runs a dedicated High-Capacity Pipeline NDT service line with cloud reporting and remote Level III audit capability.
