Round Welded Steel Pipes Hot Rolled Black Painted Boiler Pipe Non-oiled Welding Carbon Steel Spiral Weld Pipe
Piral Steel Pipe
It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip according to a certain spiral angle(called forming angle) into a tube blank, and then welding the tube seam together. It can be made with a narrower Strip steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness, and the welded pipe shall be ensured that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the requirements.
carbon steel pipe helical seam spiral welded steel pipe Used For Oil And Gas Pipeline
API 5L spiral steel pipe and tube with well steel tube is mainly used in water supply, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid delivery: water supply, drainage, sewage treatment works, mud, marine water. For gas transportation with: gas, steam, liquefied petroleum gas. For the structure with: for piling pipe, for the bridge; terminal, road, building structure with the tube, such as marine piling.
Application:Fluid Pipe, Boiler Pipe, Drill Pipe, Hydraulic Pipe, Gas Pipe, OIL PIPE, Chemical Fertilizer Pipe, Structure Pipe
