How to prevent surface defects of stainless steel tee

The extrusion molding method of stainless steel tee joints uniquely uses emulsion as the filling medium to meet the requirements of energy saving and environmental protection. The tee joints extruded by this product are easy to clean. Will cause pollution to the stainless steel metal tee and the environment. In addition, the invention originally wraps a layer of plastic film on the stainless steel tube blank, which effectively prevents defects on the surface of the formed tee joint, and significantly improves the processing quality of the tee joint. The extrusion molding method of stainless steel tee joint includes: 1) preparing a stainless steel tube blank covered with a plastic film on the surface; 2) extruding the product stainless steel tube blank to obtain a semi-finished tee joint, in which the tube is filled with a liquid system The liquid filling medium is an emulsified liquid prepared by emulsified oil and water; 3) Solid solution treatment, surface grinding and groove processing are carried out on the semi-finished products of the three-way joint of the product.
