Stainless steel pipe fittings are a kind of pipe fittings. It is made of stainless steel, so it is called stainless steel pipe fittings. Stainless steel pipe fittings include: stainless steel elbow, stainless steel tee, stainless steel tee, stainless steel head, stainless steel flange, etc.


Reducing the diameter of the reducer is to heat one end of the stainless steel large-diameter and large-diameter tube to a red-hot state, and then use a hammer to reduce the diameter. , Commonly known as "big head", or "reducing."


Sometimes the diameter difference between the two ports of the stainless steel head is too large, so one end of the large-diameter tube is cut off several curved triangular pieces, and then heated to a red-hot state, and smashed with a hammer to make the cut notch close to Form the seams together, round the small ports formed, and weld the seams.

According to the reducing diameter of the reducer, it can be divided into one press forming or multiple press forming. In addition to the use of steel tubes as raw materials for stamping and forming, some sizes of large and small heads can also be produced by stamping with steel plates. The shape of the die used for drawing is designed with reference to the size of the inner surface of the big and small heads, and the blanked steel sheet is punched and drawn with a die.


In addition to the use of steel pipes as raw materials for the production of large and small heads, some specifications of large and small heads can also be produced by stamping with steel plates.


Big and small (reducing pipe) is a kind of pipe fittings used for pipe caliber. The forming process usually used for stainless steel heads is reduced-diameter pressing, expanded-diameter pressing, or reduced-diameter-plus-diameter pressing. For some specifications of reducers, stamping can also be used. Reducing / expanding forming The reducing diameter forming process of the big and small heads is to put a tube blank with the diameter equal to the big end of the big and small heads into a forming die. By pressing in the axial direction of the blank, the metal is moved along the cavity and contracted to form. .
