Seamless steel pipes by applications
Seamless pipes are widely used in nuclear devices, natural gas, petrochemical, shipbuilding and boiler industries. Seamless pipe occupies 65% of the market share of China's boiler industry.
Main customers in the international market: Alston, bucke, SIEMENS Austria, Brazil petroleum, Dou Shan heavy industries, Hyundai, Essar, BHEL..
Seamless steel pipes application for heat exchange tubes, streaming tubes, low and medium pressure boiler water wall, economizer, reheater, superheater and steam pipeline.
Tubes for Mechanical and Automobile
Seamless Steel Tubes for Mechanical and Automobile usage for Backbone of Automobile and rear axle tube, manufacturing and processing of precision equipments, instruments and apparatus.
Boiler tubes need to withstand high pressure and temperature.
Heat exchange tubes are intended for heating or cooling process fluids, they are for example suitable for closed circuit cooling of electrical equipment using demineralised water and for cooling water soluble oil solutions in quenching tanks.
The Seamless steel pipe for ship building usage are mainly used for Level 1& Level 2 pressure pipe in piping system, boiler and super-heated unit of shipbuilding.
Seamless Steel Tubes for Mechanical and Automobile usage for Backbone of Automobile and rear axle tube, manufacturing and processing of precision equipments, instruments and apparatus.
Our fluid seamless steel tubes are widely used for fluid transport, water conveying (sewage water discharge, water divert project), oil and natural gas long distance transmission as well as fluids.
Low temperature service seamless pipes are application for low-temperature pressure container piping by the main standard GB/T18984-2003, ASTM/ASME A/SA333 with steel grade 16MnDG, 10MnDG, A333 Gr.1, Gr.3, Gr.6
The line pipes can be used for a wide range of petrol and gas transportation under sour service environment.
ASTM A199/A199M-92 Specification for Seamless Cold-Drawn Intermediate Alloy-Steel Heat-Exchanger tubes and Condenser Tubes.
Used as the pipes on the heated side of low and medium pressure boilers(normally with operating pressure not higher than 5．88Mpa and operating temperature below 450 oC), as the pipes on the heated sides of high·pressure boilers, economizers, overheaters, reheaters and pipes for petrochemical industry(with the operating pressure above 9．8Mpa and operating temperature ranging between 450C-650C1)
