The wall thickness of stainless steel water pipe is the key to determine its connection strength. When the wall thickness is reduced below the safety factor, the reliability must be reduced by several grades. In fact, pipe wall thickness is a surface requirement. Its quality requirements are not only to ensure the strength of the pipeline connection, but also to ensure the seismic performance in various environments, the performance of the pipeline under various external impacts, the service life of the product in the hidden project and the corrosion allowance. At present, the national standard wall thickness of stainless steel water pipes in the domestic stainless steel water pipe market and manufacturers is 0.8-2mm, under the same nominal diameter (DN).

The choice of stainless steel water pipe depends on the production process of the manufacturer. The process depends on the details of the product, and the details determine the quality of the water pipe. For example, how the manufacturer welds the water pipe, whether the inner wall of the water pipe is balanced and smooth, whether the weld in the pipe is straight and neat, and whether the weld and its surroundings are significantly discolored; The body should be flat and straight; Stainless steel pipe mouth incision should be smooth, no burrs, flash. In all walks of life, when we choose products, in order to buy qualified products, we must first choose big brand manufacturers. Stainless steel water pipes and pipe fittings production enterprises shall have product quality certificates and related material quality inspection reports. The raw materials, specifications, production batch number and the name of the production enterprise shall be marked on the pipes and fittings. A good product attaches great importance to its own brand and must have factory certification.
