Stainless steel drinking water pipe and stainless steel pipe fittings, using German double pressurization connection technology, change the traditional water supply materials and methods, solve the problem of secondary pollution of drinking water, and are known as the green pipe of the twenty-first century. Stainless steel sanitary pipe is a kind of long steel developed with a hollow section and no joints in neighboring countries. The thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, its processing cost will rise significantly; The process of the product determines its limited performance, and the accuracy of the general seamless steel pipe is low: the wall thickness is uneven, the brightness of the inner and outer surfaces of the tube is low, the cost of sizing is high, and there are pockmarks and black spots on the inner and outer surfaces that are not easy to remove; Its inspection and shaping must be processed offline. 304 or 316L stainless steel pipe, sanitary grade steel pipe, stainless steel pipe (manufacturer, specification); Therefore, it reflects its superiority in high pressure, high strength and mechanical structure materials.
