Tube shall be manufactured utilizing steel conforming to the requirements of ASTM A1008/A1008M and A1011/A1011M with a typical minimal yield energy of 30,000 psi. The metal shall be chilly fashioned and welded into tube using the high frequency induction welding course of capable of forming a weld bead stronger than the father or mother metal. The tube shall be subsequently handed by way of a molten zinc bath able to applying the required exterior zinc coating thickness.
The zinc layer thickness could also be in the range of 5 to 30 micrometers (µm). Hunan great steel pipe co.,ltd as an expert steel pipe producer for 24 years with superior quality, goog service, well timed supply and sincere cooperation. The type of water that runs via the pipes has an impact on the life expectancy. Hard water has extra impurities corresponding to magnesium and calcium ions.
