(1) During the heat treatment process, the cause of the geometric change of the large-diameter steel pipe is the heat treatment stress. Heat treatment stress is a relatively complicated issue. It is not only the cause of defects such as deformation and cracks but also an important means to improve w

Anti-corrosion steel pipe uses the preservation process to protect the steel pipe away the corrosion. It is trying our best to get a long lifetime in the steel pipe. Product name: anti-corrosion steel pipeSize: 600x5x6000mmStandard: ASTM A53Application: Energy Transport ProjectLocation: Brazil

The forming methods for manufacturing large-diameter straight seam welded steel pipes include UOE forming, row forming (CFE), CE forming, etc. For the last process of most forming methods, the full-length diameter expansion of the welded tube blank is performed again to improve the shape of the weld

Seamless steel pipes are widely used. General-purpose seamless steel tubes are rolled from ordinary carbon structural steels, low alloy structural steels, or alloy structural steels with the highest yield, and are mainly used as pipes or structural parts for conveying fluids. .2. There are three typ
