- API 1169
- API Recommended Practice 1169 sets minimum inspection requirements for onshore pipeline construction, covering preconstruction through restoration.
- Construction inspection plan
- A project-specific document defining inspection scope, hold points, frequencies, documentation, and responsibilities before pipeline construction begins.
- Hold point
- A defined stage in construction where work must stop and inspector acceptance is required before the activity may proceed.
- Right-of-way verification
- Preconstruction check confirming landowner agreements, permits, access, boundaries, and environmental constraints match approved construction drawings before clearing.
- Heat number traceability
- A unique identifier linking pipe or components to their mill test report, enabling verification of chemistry and mechanical properties.
- Mill test report
- Documentation from the manufacturer reporting chemical composition and mechanical test results for a specific heat or lot of pipe.
- Equipment calibration records
- Current documentation showing inspection and test equipment readings are traceable to recognized standards within the required calibration interval.
- Pipe storage inspection
- Checks that pipe is supported, restrained, protected from damage, and kept clean while stored before installation.
- Trench spoil setback
- Excavated material and equipment must be placed away from trench edges per project requirements to reduce surcharge and prevent cave-in.
- Competent person
- An individual capable of identifying existing and predictable excavation hazards and authorized to take prompt corrective action.
- Bedding requirement
- Specified material and thickness placed under and around pipe to provide uniform support and protect coating from damage.
- Trench water control
- Use of pumps, ditches, or diversions to keep the trench bottom dry and stable during excavation and pipe installation.
- Bend radius check
- Verification that field bends do not exceed specified radius and that pipe wall wrinkling or ovality remains within allowable limits.
- Internal line-up clamp
- Device inserted inside pipe ends to align the joint, maintain root gap, and reduce misalignment before welding.
- Pipe sag inspection
- Check that supported pipe has no unsupported spans or sags exceeding project limits before backfill.
- Cold field bend
- Field bending performed without heating, using a bending machine that controls curvature and avoids excessive ovality or coating damage.
- Welding Procedure Specification
- A qualified document specifying welding variables, filler metal, preheat, and technique required to produce sound pipeline welds.
- Procedure Qualification Record
- Record documenting the test weld and destructive results that qualified a welding procedure specification for its intended use.
- Welder qualification test
- Performance test demonstrating a welder can produce welds meeting specified visual and nondestructive examination acceptance criteria.
- Weld visual inspection
- Examination of completed welds for defects such as cracks, undercut, porosity, high-low misalignment, and inadequate cap profile.
- Surface preparation grade
- Cleanliness level required before coating application, commonly defined by standards such as near-white or commercial blast cleaning.
- Dry film thickness
- Cured coating thickness measured after application and compared with specification minimum and maximum limits.
- Holiday detection
- Electrical test used to locate pinholes, voids, or thin spots in a protective pipeline coating.
- Cathodic protection
- System that applies electrical current to buried pipe to reduce corrosion by making the pipe surface cathodic.
- Hydrostatic test
- Pressure test in which the completed pipeline section is filled with water and held at specified pressure to verify strength and leak tightness.
- Test pressure hold time
- Specified duration that a pipeline test section must remain at test pressure without pressure loss before acceptance.
- Pressure test water quality
- Water used for hydrostatic testing must meet project limits for corrosivity, solids, chlorides, and biological content.
- Restoration inspection
- Verification that disturbed land is regraded, stabilized, revegetated, and drainage restored according to permits and project plans.
- Excavation protective system
- Sloping, benching, shoring, or shielding used to protect workers from cave-ins in trenches and excavations.
- Spill prevention plan
- Site-specific plan identifying fuel and chemical storage, containment, inspection, and response procedures to prevent environmental releases.
- Confined space entry permit
- Written authorization required before entering a confined space, documenting hazards, atmospheric testing, attendants, and rescue arrangements.
- Environmental permit compliance
- Inspector verifies construction activities stay within wetland, waterway, erosion, noise, and land-use conditions stated in project permits.
