CCS Pressure Steel Pipes and Tubes

CCS pressure steel pipes and tubes are a kind of marine steel tubes used for pressure piping. The CCS pressure steel pipes and tubes are approved by China Classification Society. Materials of the tube conform to the requirements of GB/T 5312, and the specifications meet the standard GB/T 17395. Please contact us if you require other specifications, and we will customize pipes for you. There are five steel grades for the pipe: 320, 360, 410, 460, 490. The CCS pressure steel pipes and tubes can be divided into three grades,,, according to design pressure and design temperature. Excepting the CCS pressure steel pipes and tubes, we also supply CCS seamless steel pipes, CCS boiler steel pipes, CCS stainless steel pipes... Please contact us for our whole product range!

Note

1. When a pipes design temperature or design pressure meets requirements for gradeon table A , the pipe will be certified as gradepipe. When a pipes design temperature and design pressure both meets requirements for grade on table A , the pipe will be certified as grade pipe.

2. Other media refer to air, water, lubricating oil, hydraulic oil...

3. Grade pipes can be made according to national standards agreed by CCS.
