Stainless steel industrial pipes are used for liquid transportation and heat transfer, so there are certain regulations on the inner wall thickness and the corrosion resistance, heat resistance and compression resistance of pipes; decorative pipes are used in sanitary ware, guardrails, and lighting, so they will affect the corrosion resistance, heat resistance and pressure resistance of pipes. The ornamental value and load-bearing capacity of the surface are stipulated; the main purpose determines the process and implementation regulations of the pipe fittings. 1. Stainless steel industrial pipe: Generally, the thickness is above 3.0mm, and there are regulations on materials, electric welding, phosphating and internal grinding and polishing processes. 1. Material: Industrial production fluid pipes generally use 304, 316, 316L anti-corrosion 300 series metal materials; when replacing heat pipes, the heat resistance of pipe fittings is more important, and 310s, 321 stainless steel with heat resistance is generally used. plate. 2. Electric welding: Whether it is a fluid pipe or a heat exchange pipe, it belongs to medium and low pressure pipes, so the electric welding process is very critical. Generally, arc welding technology is used, and mixed rare gas is added to carry out weld maintenance to avoid weld air. Oxidation occurs in empty welding, leakage welding, etc. 3. Phosphating treatment: Most of this process is a necessary process for industrial

The important elements in 304 stainless steel pipes are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. The common judgment situation in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as a 304 stainless steel pipe. This is why the industry calls this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards have very clear regulations for 304 stainless steel pipes, and these product standards have some differences for different shapes of stainless steel. Therefore, Ni is a very important element for 304 stainless steel pipe, which directly determines its corrosion resistance and its value.
