ASTM A 106 Black Painted Seamless Steel

Product Description The seamless steel pipe is made of a whole piece of metal and has no seam on the surface.According to the production method,seamless pipes are divided into hot tube, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking, etc. According to the cross-sectional shape, seamless steel pipes are divided into circular and special-shaped pipes. Special-shaped pipes have many complex shapes, such as square, oval, triangle, hexagon, melon seeds, star and finned pipes.Seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemical industry, boiler tubes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.  Usually made of high-quality carbon steel, such as 10, 20, 30, 35, 45, etc., such as low-alloy steel, such as 16Mn, 5MnV, etc., etc., made of hot-rolled or cold-rolled steel, such as 40Cr, 30CrMnSi, 45Mn2 , MOMnB, etc. Mainly made of low carbon steel,…
