Inspection connects the material, manufacturing process and delivered part with a documented acceptance plan.
Inspection methods and equipment
Metallography
- Standard reference
- GB/T 13298 / ASTM E3
- Equipment
- Inverted metallurgical microscope
- Example acceptance reference
- No visible pores / inclusions in the examined section
Tensile test
- Standard reference
- GB/T 228.1 / ASTM E8/E8M
- Equipment
- Universal testing machine
- Example acceptance reference
- Reference tensile strength ≥1050 MPa for the specified material condition
Penetrant examination (PT)
- Standard reference
- JB/T 9218 / ASME BPVC V
- Equipment
- Penetrant inspection system
- Example acceptance reference
- No linear indications; acceptance class confirmed in the inspection plan
Ultrasonic examination (UT)
- Standard reference
- ASME BPVC V
- Equipment
- Ultrasonic inspection system
- Example acceptance reference
- Proposal reference: no defect ≥Φ2 mm; technique and sensitivity agreed for the part
Dimensional inspection
- Standard reference
- ISO 10360
- Equipment
- Coordinate measuring machine
- Example acceptance reference
- ±0.02 mm
Hardness
- Standard reference
- ASTM E18
- Equipment
- Rockwell hardness tester
- Example acceptance reference
- HRC 32–38
Flow calibration
- Standard reference
- ISO 5167
- Equipment
- Flow calibration bench
- Example acceptance reference
- Deviation ≤±5%
Additional capabilities in the company profile include industrial CT scanning and 3D scanning for dimensional reconstruction. Test selection and acceptance limits follow the material, heat treatment, geometry and customer specification. The example strength and hardness values do not apply to every alloy.
General additive manufacturing framework
ISO/ASTM 52900 terminology; ISO/ASTM 52920 qualification; ASTM F3303 powder-bed fusion; GB/T 35351 terminology.
Non-pressure-retaining repair qualification
The proposal describes archived WPS / PQR for non-pressure-retaining sealing surfaces, with T/LASERJS 001-2024 and GB/T 19866 among the referenced documents. The material pair and repair scope are checked for each order.
Pressure-part qualification by project
NB/T 47014 and ASME BPVC Section IX support project-specific procedure qualification. API 20S AMSL 2 / 3 is described as a customer-driven qualification route. ASME PTB-13 addresses additive-manufactured pressure-retaining components. These are project routes, not blanket acceptance of pressure parts.
Laboratory records and traceability
CNAS / ISO 17025 laboratory scope, material batches, process records, inspection results and assembly records are linked to the delivered part. Request the relevant scope and report for the order.
For non-pressure-retaining wear parts: valve trim, seats and sealing surfaces. Pressure-retaining components require project-specific qualification before acceptance.
