What are stainless steel pipe fittings?

Stainless steel pipe fittings belong to one of the pipe fittings. It is made of stainless steel so it is called stainless steel pipe fittings. Stainless steel pipe fittings include: stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel heads, stainless steel flanges, etc. Reducing the diameter of the reducer is to heat one end of the large-diameter stainless steel tube to a red hot state, and hit it with a hammer to reduce the diameter. The 20# steel hot-pressing the small- and small-diameter reducer becomes a pipe fitting with a large end and a small end. , Commonly known as size head, or variable diameter. Sometimes the difference between the diameter of the two ends of the stainless steel is too big, so cut off a few curved triangular pieces at one end of the large-diameter pipe, and then heat it to a red hot state, hit it with a hammer, and make the cut notch close to it. The joints are formed together, and the small ports formed are rounded, and then the joints are welded. According to the size of the reduced diameter of the reducer, it is divided into one-time press forming or multiple press forming. In addition to the use of steel pipes as raw materials for the production of small and small heads, stamping and forming can also be produced by stamping and forming processes with steel plates for some specifications. The shape of the punch used for drawing is designed with reference to the size of the inner surface of the size head, and the blanked steel plate is punched and stretched with the punch. In addition to the use of steel pipes as raw materials to produce the small and small heads, some specifications of the small and small heads can also be produced by the stamping process of steel plates. The size head (reducing pipe) is a pipe fitting used for the diameter of the pipe. The commonly used forming process for stainless steel size heads is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for reducing diameter pipes of certain specifications. The shrinking forming process of reducing/expanding forming size head is to put a tube blank with the same diameter as the big end of the size head into the forming mold, and press it along the axial direction of the tube blank to make the metal move along the mold cavity and shrink into shape. .
