kAWater quality requirements. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, and the chemical composition meets the standard requirements.

The resistance, coefficient of linear expansion, thermal conductivity, quality, hot melt and magnetism of stainless steel pipe will change greatly at low temperature. Resistance, linear expansion coefficient decreases at low temperature; The thermal conductivity and mass heat capacity decrease sharply at low temperature; Youngs modulus (longitudinal modulus) increases when the temperature decreases. Because the austenitic series stainless steel pipe has MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature), martensite can be formed when it is kept below MS point. The formation of martensite at low temperature makes the representative steel sus (Cr-Ni) of austenitic stainless steel non-magnetic at room temperature and magnetic at low temperature.
