Gansu 304 stainless steel is heat-resistant steel, tensile strength at 400 degrees still 412Mpa, higher than the ordinary steel tensile strength at room temperature. Lined with stainless steel composite steel high temperature performance is very good, can be used to transport the hot water, boiling water, steam. Welded steel pipe to ensure a 15% elongation, Lanzhou 304 stainless steel tube elongation ensure that more than 25%, stretchy expansion of the outer pipe, lined elongation, better stainless steel tube to avoid When the water freezes in the tube expands to brittle fracture. Gansu 304 stainless steel tube at 20 degrees corrosion rate of less than 0.1 mm per year, the use of stainless steel lined composite steel pipe together with the stainless steel welded pipe fittings and stainless steel flanges, can be used to transport chemical fluid. Stainless steel pipe from the fluid in the course of corrosion, stainless steel tube body free of impurities into the fluid, After testing, the content of various metal elements detected in the high-sensitivity detection equipment, much lower than the specified value, health permits orders. Due to Lanzhou 304 stainless steel pipe together with stainless steel threaded pipe fittings, stainless steel flanges, stainless steel welded pipe fittings, fluid and the outer pipe is not in contact with the fluid only contact with stainless steel, the stainless steel lined composite steel pipe instead of pure stainless steel pipe used to transport drinking water purification.
