Pipeline Integrity
We assess and protect pipeline systems against corrosion across their service life. Our team delivers coating weld inspection (CWI), hardness/strength/ductility testing, and direct assessment work that holds up to regulator scrutiny and keeps product moving safely.
Pipeline integrity services at Superior Integrity Services assess and protect transmission and distribution pipeline systems against corrosion across their service life. The team delivers coating weld inspection, field hardness/strength/ductility testing, and direct assessment programs (ECDA, ICDA, SCCDA) with GPS-referenced data that supports 49 CFR 192/195 (PHMSA) compliance and operator integrity management plans.

Common questions
Pipeline Integrity FAQs
What direct assessment programs does SIS perform?
SIS performs ECDA, ICDA, and SCCDA direct assessment programs, including soil and coating surveys, GPS-referenced indication records, and PMI and dent/wrinkle measurement at each survey point.
How does SIS pipeline integrity work support PHMSA compliance?
Our integrity work supports compliance with 49 CFR 192/195 (PHMSA), NACE SP0169, and operator-specific integrity management plans. All data is field-verified and delivered in formats ready for your IMP records.
What is coating weld inspection (CWI)?
CWI covers coating condition surveys, holiday and adhesion checks, and repair documentation on pipeline coatings — protecting the system's primary defense against external corrosion.
Can SIS verify pipeline material properties in the field?
Yes. SIS performs field hardness testing, material property verification, and weld HAZ assessment, delivering hardness and material test records that support integrity decisions without cutouts.
What deliverables come with a pipeline integrity assessment?
Each project ships with GPS-referenced survey data, deficiency and corrosion maps, prioritized remediation recommendations, hardness and material test records, and IMP-ready summary reports.
