Carbon Welded Structural Sprialing Steel Pipe;Spiral welded high frequency steel tubes (sy5038-83) for confined fluids, welded by high frequency lap welding method, for confined fluids.The steel pipe has strong bearing capacity and good plasticity, which is convenient for welding and processing.Spiral seam arc-welded steel tube (sy5037-83) for general low-pressure fluid transportation is adopted, which is made by double-sided automatic arc-welding or single-side welding method and used for water, gas, air and steam and other general low-pressure fluid transportation.Screw tube material: Q235A, Q23b,0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0cr18ni11nb. Q345 L245 L290 X42 X46 X70 X80.Spiral welded steel pipe refers to the steel belt or steel plate bending deformation into the shape of round, square, and then welded into the surface of the joint steel pipe.According to the shape of welding seam, it can be divided into straight welded pipe and spiral welded pipe.Welded steel tubes are used in oil drilling and machinery manufacturing.
