Stainless steel tees to prevent surface defects

　　The extrusion forming method of stainless steel tees originally adopts emulsion as liquid filling medium to meet the requirements of energy saving and environmental protection. The stainless steel tees formed by extrusion of this product is easy to clean, and the emulsion filled with liquid medium in the pipe can be reused without polluting the stainless steel tee and the environment. In addition, the invention originally wraps a layer of plastic film on the stainless steel tee blank in advance, effectively prevents defects on the surface of the formed stainless steel tees, and remarkably improves the processing quality of the stainless steel tees.

　　The extrusion molding method of stainless steel pipe fitting tee includes:

　　1) prepare stainless steel tee with a plastic film on the surface.

　　2) The stainless steel tube blank of the product is extruded to obtain the semi-finished product of the stainless steel tees, in which the filling medium in the tube filling system is the emulsion made of emulsified oil and water.

　　3) solid solution treatment, surface grinding and groove machining for semi-finished products of stainless steel tees.
