Equipment we inspect in China

Static, rotating and electrical equipment and bulk materials for oil & gas, petrochemical, refining and power projects.

• Valves

  We attend valve factories in China on your behalf to review material certificates, witness API 598 / API 6D pressure tests, run PMI and release the shipment only when it matches your purchase order.

  API 6D pipeline valves / API 598 inspection and testing / API 600 / API 602 gate valves / API 608 ball valves, API 609 butterfly valves

• Pressure vessels and heat exchangers

  We follow pressure vessels and heat exchangers through fabrication in China, review welding and NDE records, witness the hydrostatic test and check the manufacturer's data book before release.

  ASME BPVC Section VIII Div. 1 and Div. 2 / ASME Section IX welding qualifications / ASME Section V non-destructive examination / TEMA and API 660 shell-and-tube heat exchangers

• Pipe fittings and flanges

  We inspect flanges and fittings at forging and fitting plants in China, checking material certificates, heat treatment, dimensions, face finish, hardness and PMI before the goods are packed.

  ASME B16.5 and B16.47 flanges / ASME B16.9 butt-weld fittings, ASME B16.11 forged fittings / MSS SP-75 high-strength fittings, MSS SP-44 steel pipeline flanges / ASTM A105, A182, A234, A350, A403, A694

• Line pipe

  We place inspectors at pipe mills in China to follow API 5L PSL1 and PSL2 production, witness mechanical tests and hydrotests, check dimensions and coating, and supervise loading.

  API 5L PSL1 / PSL2 and ISO 3183 / DNV-ST-F101 for offshore pipelines / ASTM A106, A53 and A333 carbon steel pipe / ASTM A312 and A790 stainless and duplex pipe

• Structural steel

  We inspect pipe racks, modules, platforms and building steel at fabrication yards in China, from welding qualifications and fit-up to NDE, coating and packing.
