Inspection and Test Plan for Method Statement – Oil & Gas Pipeline Welding Works (WPS, Welder Qualification, Fit-Up, Preheat, Welding, NDT, Repairs, Traceability)
AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.
More than a static template
Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.
- AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
- Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
- Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
- Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.
What you can customize
When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:
- Inspection activity — Description of what is being inspected.
- Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
- Responsibility — Contractor, subcontractor, engineer, or client.
- Frequency — How often the inspection occurs.
- Acceptance criteria — Referenced standard or specification requirement.
- Records — Forms, test reports, or checklists required as evidence.
Why this ITP is used
To ensure each welding stage is verified against approved WPS and project specifications, achieving consistent quality and compliance.
Who uses this inspection and test plan
QC inspectors, welding supervisors, NDT personnel, and the Client/Engineer for hold/witness activities.
When this ITP is prepared and submitted
Applied before, during, and after welding—at fit-up, preheat, root/fill/cap, VT, NDT, repairs, and final acceptance.
Who receives or approves this ITP
Client/Engineer for review, approval, and witnessing as defined by the ITP.
Inspection scope
Covers material verification, fit-up, preheat/interpass, in-process parameters, VT, RT/AUT, MT/PT, hardness (if required), repairs, and release.
Typical hold, witness, and review points
Hold: Fit-up, post-VT prior to NDT, repair verification, final release. Witness: Preheat checks, weld mapping/traceability verification.
Typical inspection records
Fit-up reports, temperature logs, welding parameter logs, VT/NDT reports, repair logs, calibration certificates, weld maps and release forms.
Important approval note
This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.
Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.
Inspection and test plan
| Activity | Inspection / Test | Acceptance Criteria | Responsibility | Record |
|---|---|---|---|---|
| Material verification and joint prep | Visual/dimensional check of pipe grade, bevel, heat marks | Matches IFC; bevel geometry per WPS; cleanliness SSPC-SP1 | QC Inspector | Material/JPC checklist and photos |
| Fit-up inspection (Hold) | Gap/hi-lo using gauges; alignment at 4 quadrants | Root gap 2–3 mm; hi-lo ≤1.6 mm or per WPS; joint ID marked | QC Inspector; Witness: Client Rep | Fit-up report (H) |
| Preheat/interpass verification | IR thermometer/temp crayons; dew point measurement | Preheat ≥ WPS; interpass ≤ WPS; surface ≥3°C above dew point | Welder / QC Inspector | Preheat log; environmental checklist |
| In-process parameter check | Amps/volts/travel speed spot checks | Within WPS ranges and heat input limits [Verify] | Welding Supervisor / QC | Welding parameter log |
| Visual inspection (Hold) | VT per API 1104/ISO 17637 | Surface acceptance per API 1104; cap reinforcement 1–3 mm; undercut within limit | QC Inspector; Witness: Client Rep | VT report (H) |
| NDT – RT/AUT | RT per ISO 17636 or AUT per ISO 10863 | Acceptance per API 1104/project | NDT Level II / QC review | NDT report + film/data |
| Surface NDT (MT/PT) – as required | MT ASTM E1444 / PT ASTM E165 | No relevant indications beyond acceptance level | NDT Level II / QC | MT/PT report |
| Hardness testing (if sour service) | Portable hardness HV10/HV5 | HAZ/cap hardness ≤ project limit (e.g., 250 HV10) [Verify] | QC / NDT Level II | Hardness report |
| Repair verification (Hold) | MT/PT after removal; VT and RT/AUT after repair | Meets API 1104 acceptance; repair cycles within limit | QC Inspector; NDT Level II | Repair log; updated NDT |
| Final acceptance and release to coating (Hold) | Document review + VT of cleaned joint | All ITP steps closed; NDT accepted; weld ID mapped | QC Inspector; Client Rep | Release-to-coating form (H) |
