CCS Carbon and Carbon-Manganese Steel Pipes and Tubes

CCS Carbon and Carbon-Manganese Steel Pipes and Tubes

The carbon and carbon-manganese steel pipes and tubes is a sort of marine steel pipes certified by China Classification Society. The pipes meet the requirements of GB/T 5312. The carbon and carbon-manganese steel pipes and tubes are designed for marine boilers, heat exchangers and pressure piping. The highest working temperature of the pipes is 450℃ for boilers. The manufacture methods for pipes are WHR, WHE or WCD. There are five steel grades for the pipes: 320, 360, 410, 460, 490. We are able to provide you full selection of pipe specifications. If you want to know more details, welcome to contact us!
