What are the main functions of the three stainless steel. In the pipeline
branch will often use three stainless steel pipe fittings. The general stainless
steel three all is made of seamless pipe manufacturing technology, there are two
kinds of hydraulic and hot press forming method. The hydroforming of stainless
steel three is a forming technology branch by axial compensation expansion of
metallic materials, the hydraulic machine specialized in the entire production
process. This machine can be the three channel of the same diameter of the tube
into the liquid, through a series of processes to form stainless steel three.
The manufacturing method has the advantages of high efficiency, one-time forming
and high safety.
Because of the three stainless steel hydraulic bulging process required equipment tonnage. At present, it is mainly used in the manufacture of standard wall thickness stainless steel three pass less than DN400. The suitable forming material is low carbon steel, low alloy steel, stainless steel, which has a tendency of cold hardening. Including some non-ferrous metals, such as copper, aluminum, titanium, etc..
