Quality control and certifications
Quality is a sequence of documented checks, not a final visual inspection. The route below is applied to every order: material verification at goods-in, process checks during forging and heat treatment, dimensional and NDT inspection after machining, and a document pack that travels with the shipment.
The tests actually performed depend on the purchase order. We agree the inspection and test plan before production, so there are no surprises at the pre-shipment stage.
Certifications and documentation
ISO 9001:2015
Quality management system covering order review, manufacturing and inspection.
CE / PED 2014/68/EU
Documentation and material traceability for pressure equipment placed on the EU market.
EN 10204 3.1 / 3.2
Material certificates with actual chemical and mechanical results, traceable to the heat number.
Class approvals
Marine class approvals (ABS, DNV, BV) can be arranged for offshore and shipboard orders.
Testing methods and standards
| Test | Method | Standard | What it verifies |
|---|---|---|---|
| Chemical analysis | OES spectrometer | ASTM A751 | Confirms grade and trace elements |
| Tensile test | Universal testing machine | ASTM A370 | Yield, tensile, elongation, reduction of area |
| Charpy impact | Pendulum impact tester | ASTM A370 | Toughness at the specified test temperature |
| Hardness | Brinell / Rockwell / Vickers | ASTM E10 / E18 / E92 | Heat-treatment verification, NACE limits |
| Ultrasonic (UT) | Phased array / contact UT | ASTM A388 | Internal porosity, cracks, laminations |
| Magnetic particle (MT) | Yoke / bench | ASTM E709 | Surface and near-surface cracks in steel |
| Penetrant (PT) | Dye / fluorescent | ASTM E165 | Surface defects on stainless and machined faces |
| PMI | XRF / OES analyser | API RP 578 | Mixed-material and grade verification |
| Hydrostatic | Test bench | Per order | Leak and strength check on assemblies |
Read the NDT buyer's guide for when each method is worth specifying.
Inspection workflow
Incoming material
Certificate review, PMI, dimensional check on the raw material or forged blank.
In-process
Forging temperature and reduction records, heat-treatment charts, machining checks.
Final inspection
Dimensional report, NDT per ITP, visual and marking check, packing photos.
Documentation in every shipment
- EN 10204 3.1 material certificate with actual test results
- Dimensional inspection report with measured values
- Heat-number stamping on the part, matching the certificate
- Packing list, commercial invoice and certificate of origin
- Photos of packing before container loading
Third-party inspection
SGS, BV, TÜV, Lloyd's and customer-appointed inspectors are welcome. We provide the inspection plan, test records and access to the workshop, and schedule the witness points with advance notice.
If the order needs EN 10204 3.2 certification, tell us at the quotation stage — it changes the inspection schedule and the lead time.
