Sanitary Valve, also known as seamless stainless steel pipe, is made of steel ingots or solid billets through perforation into rough pipes, and then hot-rolled, cold-rolled or cold-drawn. The specifications of seamless steel pipes are expressed in millimeters of outer diameter * wall thickness. Stainless steel pipe (is a hollow long cylindrical steel material. Its scope of application is used as a pipeline for conveying fluids. It is mainly widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. Stainless steel pipes are made of acid-resistant and heat-resistant steel billets, which are heated, perforated, sized, hot-rolled, and cut.

The use of seamless stainless steel pipes should pay attention to the environment, where chloride ions exist. Chloride ions are widely present, such as salt, sweat, sea water, sea breeze, soil, etc. Stainless steel corrodes quickly in an environment with chloride ions, even more than ordinary low-carbon steel. Therefore, there are requirements for the use environment of stainless steel, and It needs to be wiped frequently to remove dust and keep it clean and dry.

316 and 317 stainless steel (the performance of 317 stainless steel is shown below) are molybdenum-containing stainless steels. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride corrosion, so it is usually used in marine environments.

With the development of social economy, the application of stainless steel pipes has become more and more popular. It will definitely bring new changes in various fields.
