Sanitary Valve is usually made of high-quality stainless steel pipe fittings. Stainless steel pipe fittings are a common type of pipe fittings. Its material is mainly made of stainless steel, so it is called stainless steel pipe fittings. Common types include: stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel elbows, stainless steel pipe caps, etc. According to the different connection forms, it can also be divided into socket-type stainless steel pipe fittings, threaded stainless steel pipe fittings, flanged stainless steel pipe fittings and welded stainless steel pipe fittings. The main stainless steel materials are 304, 304L, 316L, etc.

Usually, the stainless steel pipe fittings we use have a set of international standards, so if you want to buy any pipe fittings, you can buy it directly by saying its specifications, and you don’t have to worry about not being able to use it after buying it back. Depending on the environment and occasion of use, the standards of stainless steel pipe fittings are also different. Here are a few commonly used standards for stainless steel pipe fittings.
