Pipe Prefabrication

In the energy, petrochemical, mechanical and electrical industries, pressure piping is one of the keys to achieving engineering goals, STE's provides all walks of life with all types of pressure piping fabrication in the shop and on-site installation. Piping materials and construction requirements can be ASME/ASTM, PED, JIS, DIN, GB/TS and other standards. We are capable of performing all the processes required for piping operations, including material procurement, cutting and machining, forming, welding, painting, pipe support fabrication and on-site installation. The company has 5S and 6S welders certified by ASME, PED, etc. and is good at prefabricating pipes made of high strength carbon steel, special alloy steel and various types of stainless steel.


Prefabrication of high pressure piping and manifolds

STE can weld prefabricated high pressure pipes and manifolds in accordance with API, ANSI, ASME standards, and the products are mainly used in onshore and offshore oil drilling, fracturing, surface mud circulation, production pipelines, test pipelines and other high pressure rigid piping environments. And we are the long-term excellent supplier of National Oilwell (NOV) for atmospheric pressure and high pressure piping products.
