  At present, the spiral steel pipe should be widely used in the water transmission project. Because there are many materials of spiral steel pipe, which one should be selected? Let's introduce it.

  Due to the relatively small bearing pressure of water transmission pipeline, at present, the spiral steel pipe with Q235B material is mainly selected, and the executive standard is 5037 or 9711, which is commonly known as Q235B spiral steel pipe for drainage.

  Material of ASTM A106 28 inch SSAW Spiral Steel Pipe for drainage: Q235A, q23b, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, Q345, L245, L290, X42, X46, X70, X80. The spiral steel pipe for drainage uses double-sided submerged arc welding technology. The weld is spiral. The diameter of spiral steel pipe for drainage is more than DN500, which is suitable for water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction and liquid transportation: water supply and drainage. For gas transmission: gas, steam, LPG. The pipe body can be treated with heat preservation box anti-corrosion.
