The Difference Between Seamless Pipe And Welded Pipe
1. Different appearance
Seamless steel pipe: Steel tube made of a single piece of metal without seams on the surface.
Welded pipe: steel plate or strip after crimping forming welded steel pipe, general length 6 meters, the surface has welding seam.Welded pipe is made of steel plate or strip after crimping and welding.
2. use is different
Seamless steel pipe is mainly used as petroleum geology drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and automobile, tractor, aviation high-precision structural steel pipe;
Welded pipe is widely used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction.
Welded pipe for liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas; For structural use: for piling pipes, Bridges; Pipe for wharf, road, building structure, etc.
3.make raw material different
Seamless steel pipe material has ordinary and high quality carbon structural steel (Q215-A ~ Q275-A and no. 10 ~ 50 steel), low alloy steel (09MnV, 16Mn, etc.), alloy steel, stainless acid steel, etc.
Welded pipe is made of steel plate or strip after crimping and welding.
