HVG MARINE STEEL 0005

HVG MARINE STEEL 0005: Marine Carbon and Carbon-Manganese Steel Pipes and Tubes

The marine carbon and carbon-manganese steel pipes and tubes are sort of shipbuilding steel pipes made of carbon and carbon-manganese 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, full customization is available.

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…
