Built on documented results.
Superior Integrity Services is an NDT and pipeline integrity inspection company with offices across Texas, New Mexico, Oklahoma, and North Dakota. We serve operators, constructors, and fabricators with inspection crews who document every call and deliver results your integrity team can act on.
Our mission
Superior Integrity Services (SIS) specializes in non-destructive testing (NDT) and integrity services for the Oil & Gas, Power, Petrochemical, and Refining industries. Our expertise spans both new construction and maintenance projects, with a strong focus on pipeline integrity and asset reliability.
A stronger picture of every inspection.
The SIS experience is built around field readiness, clear reporting, and crews that know how to work inside live industrial schedules.
Inspection work starts with crews who understand the job site.
SIS supports operators, constructors, and fabricators with NDT and pipeline integrity crews that can mobilize quickly, follow the applicable code, and document the result clearly.
Reporting discipline is part of the service, not an afterthought.
From weld maps and image records to daily summaries and code-based packages, our work is structured so engineering, QA/QC, and operations teams can act on the same information.
What sets us apart.
- Reporting discipline — every inspection ships with documentation your engineers and regulators expect, not just a pass/fail.
- Certified crews — ASNT-certified NDT technicians and OQ-qualified evaluators staffed and ready.
- Training culture — we develop the next generation of inspectors in-house rather than borrowing credentials.
- Responsive mobilization — eight offices across Texas, New Mexico, Oklahoma, and North Dakota mean crews are close to the work.
