Marine Carbon and Carbon-Manganese Steel Pipes and Tubes

Marine Carbon and Carbon-Manganese Steel Pipes and Tubes

Product Description:

The marine carbon and carbonmanganese steel pipes and tubes are sort of shipbuilding steel pipes made of carbon and carbonmanganese steel. The pipes are applied to marine boilers and marine pressure systems. The manufacturing methods for the pipes are: WHR(WHEX), WHE, WCD(WCR). The process is seamless. We provide a full selection of pipe specifications, available for heavy wall, thin wall, large diameter, small diameter. The pipe ends is plain.

If you have any specific requirements, please feel free to contact us.

In addition to the marine carbon and carbon-manganese steel pipes and tubes, we also provide:

• Marine Stainless Steel Tubes

• Marine Seamless Steel Pipes

• Marine API Line Pipes

• Marine Seawater Corrosion Resistant Steel Pipes

• Marine Hydraulic Steel Pipes

• Marine Pressure Steel Pipes

• Marine Boiler Steel Pipes
