Mechanical Integrity and Pipeline Inspection Services
Keep assets safe, compliant, and in service with code-based mechanical integrity inspection delivered by experienced CWIs and ASNT-certified NDT personnel. From pipelines and terminals to tanks, pressure vessels, and process piping, we provide practical inspection coverage that keeps projects moving and documentation tight. Explore our API-driven programs and turnkey pipeline inspection services, including pipeline CWI inspection and ILI digs support.

Comprehensive mechanical integrity services
Where NDE is required, we coordinate and perform method-appropriate exams through in-house capabilities, including ultrasonic, radiographic (X-ray), magnetic particle, dye penetrant, and visual examinations. Explore details on ultrasonic testing and radiographic (X-ray) testing as examples of common techniques within integrity programs.
We help owners, EPCs, and contractors verify condition, fitness-for-service inputs, and compliance across new construction, repairs, and in-service assets. Our team works to AWS, ASME, AISC, API, MDOT, and DSA requirements and maintains DOT drug/alcohol, OSHA 30, and radiation safety compliance.
What we inspect and verify:
- Piping circuits, welds, supports, valves, and tie-ins
- Pressure vessels and boiler components
- Aboveground storage tanks and appurtenances
- Pipeline features, repairs, sleeves, coatings, and HDD tie-ins
- Alterations, repairs, and as-builts vs. WPS/PQR and drawings
API program coverage delivered:
- API 510 inspection for pressure vessels
- API 570 inspection for piping systems
- API 653 tank inspection for aboveground storage tanks
Representative coverage by asset type
| Asset | Typical code/standard focus | Common activities |
|---|---|---|
| Pressure vessels | API 510, ASME Section VIII | External/internal VT, thickness surveys, weld evaluations, NDE planning |
| Piping systems | API 570, ASME B31.x | Circuitization, CUI checks, supports, flange faces, weld/NDE verification |
| Storage tanks | API 653 | Shell/bottom/roof assessment, settlement, nozzle and annular ring checks |
| Pipelines | 49 CFR 192/195 practices, operator procedures | Feature verification, ILI digs, repairs/rehab oversight, coating assessment |
Pipeline integrity and ILI digs
We support integrity management programs with end-to-end pipeline inspection services. Our crews assist with planning, safe excavation oversight, anomaly verification, and thorough field documentation so that tool findings translate into actionable, traceable decisions.
Key pipeline services:
- ILI digs: locate features, expose safely, verify indications (MFL/geometry/crack tools), assess coatings, measure wall loss, and validate repairs
- Pipeline CWI inspection: confirm weld identification, procedure conformance, welder continuity/ID, and acceptance per codes and operator procedures
- Field NDE mapping: UT thickness/grids, MT/PT for surface-breaking indications, RT as required, with results captured to project logs
- Coating/CP observations: holiday checks, adhesion notes, and recoat quality observations when in scope
For crew augmentation or independent oversight on complex digs, we can provide third-party welding inspection to keep quality and documentation unbiased.
API-driven programs and coverage
Our integrity work is anchored to applicable API programs so you can demonstrate traceable, repeatable compliance:
API 510 inspection of vessels, including visual, NDE coordination, thickness data, and report packages fit for jurisdictional or client audits
API 570 inspection of piping circuits, with isometric updates, CUI screening, support checks, and data roll-up for RBI inputs when directed
API 653 tank inspection, addressing shell/bottom/roof condition, settlement, nozzle fit-up, floor plate UT, and repair oversight when authorized

Our mechanical integrity process
Plan and scope
- Review drawings, WPS/PQRs, historical inspection records, and previous ILI runs
- Define code basis, inspection intervals, and NDE strategy
- Establish hold points and documentation aligned to your turnover package
Execute and capture
- Perform code-based visual examination and verification of welding, materials, and repairs
- Apply targeted NDE: UT thickness, MT/PT for surfaces, VT levels, and RT when required
- Track corrective actions and produce daily field logs with photo evidence
Deliver and support
- Compile structured reports, findings, and recommendations with clear dispositions
- Coordinate closeout walk-downs and final acceptance
- Stay available for audits, regulator or owner questions, and follow-on work
Documentation and reporting
Reliable documentation is central to every integrity assignment. Typical deliverables include:
- Code-referenced reports for mechanical integrity inspection
- API checklists and summary sheets (510/570/653)
- Weld maps, NDE technique sheets, and examiner qualifications
- UT/MT/PT/RT results, thickness data, and corrosion rates when applicable
- Photo logs, feature verification forms for ILI digs, and repair validation records
- Final acceptance letters and punchlist closeout
If you need program-level standardization across sites or assets, we can align templates and processes to your CMMS or owner-operator standards. See industries and environments we support on our industries we serve page.
Safety, compliance, and mobility
Our inspectors maintain OSHA 30, radiation safety, and DOT drug/alcohol compliance. We regularly cover the lower half of Michigan and work throughout Indiana, Ohio, and Illinois, mobilizing nationwide to support the right project requirements.

FAQs
Do you perform API 510, 570 and 653 inspections?
Yes. We deliver API 510 for vessels, API 570 for piping systems, and API 653 for aboveground storage tanks. We can bundle these within broader mechanical integrity programs and integrate required NDE. See our API inspections.
Can you support pipeline CWI and integrity dig work?
Yes. We provide pipeline CWI inspection at repairs, tie-ins, and sleeves, plus ILI verification digs with NDE mapping and repair validation.
Do you travel to pipeline and plant sites?
Yes. We maintain strong Midwest coverage and mobilize nationwide as projects require.
Can you assist with ILI verification support?
Yes. We plan and execute verification digs, document findings against tool indications, and support repair closeout.
What documentation is provided?
Code-cited reports, API program checklists, NDE records, weld maps, thickness data, photo logs, and final acceptance or punchlist closeout.
What does mechanical integrity inspection cost?
Pricing depends on scope, code program(s), access, NDE methods, and deliverables. Share drawings and schedule on our contact our team page for a fast quote.
