ASME Pressure Vessel U Stamp Pressure Storage Tank A2 A3 Grade

Pressure Vessel, ASME U‑Stamp Pressure Vessel, A2/A3 Grade Pressure Vessel, Storage Tank, Column Tower, Heat Exchanger Vessel for Power Plant, Coking, Chemical, Custom Industrial Pressure Equipment

All pressure vessels are strictly designed according to GB150, ASME BPVC Section VIII‑1, IBR, PED, JIS and KS codes. Fabrication follows validated WPS & PQR welding procedures, with integral post‑weld stress‑relief heat‑treatment for heavy‑wall shells and critical weld joints. Every finished unit undergoes 100% full‑range UT, RT, MT, PT non‑destructive testing, plus hydro‑static pressure test at 1.5 times of design pressure and tightness inspection before shipment. Complete material test certificates(MTC), full NDT inspection reports, design calculation sheets and full export‑oriented technical documentation are provided for global project acceptance. Our pressure vessels have been exported to over 30 countries across Southeast Asia, Central Asia, Middle East, Japan and South Korea, widely adopted in new‑project construction, equipment upgrading and pressure‑vessel replacement & revamping works.

Main Features

1. Large‑scale heavy‑duty manufacturing capability: Equipped with heavy‑duty plate rolling, automatic girth welding and integral furnace heat‑treatment facilities, annual output up to 50,000 tons, capable of undertaking oversized, thick‑wall pressure‑vessel EPC project orders.
2. Multi‑national authoritative certification system: Possess Chinese A2 pressure‑vessel manufacturing license together with ASME U‑Stamp, complying with GB150, PED, JIS, KS, meeting acceptance requirements for global chemical, coking and power‑plant tender projects.
3. Diversified corrosion‑resistant material portfolio: Carbon steel, low‑alloy steel, stainless steel, duplex stainless steel and high‑alloy clad plate optional, tailored for corrosive coke‑oven gas, high‑pressure steam, chemical medium and variable temperature working conditions.
4. Full‑chain in‑house integrated processing: Plate cutting, heavy‑duty rolling, nozzle assembly, all‑position automatic welding, post‑weld heat‑treatment and multi‑stage inspection are all completed internally without outsourcing.
5. Traceable multi‑stage quality supervision: Raw material incoming inspection → weld‑joint intermediate NDT → finished‑product comprehensive NDT → 1.5×design‑pressure hydro‑static test, each pressure vessel keeps complete traceable manufacturing records.
6. Full drawing‑based customized engineering service: Provide thermal‑mechanical calculation, 3D modelling and custom fabrication according to clients’ design pressure, operating temperature, medium property, installation dimension and specification requirements.
7. Rich cross‑industry project references: Mature operating cases for coking chemical recovery, coal‑fired power plant auxiliary system, waste‑heat utilization and petro‑chemical processes, reliable for long‑term continuous pressure‑bearing operation.
