How do stainless steel tees prevent surface defects?

　　1. Prepare stainless steel tee blanks with plastic film on the surface;

　　2. Extrude the stainless steel tee blank of the product to obtain the semi-finished product of the stainless steel tee joint. The liquid filling medium in the tube filling system is an emulsified liquid made of emulsified oil and water.

　　3. Solution treatment, surface grinding and grooving of semi-finished stainless steel tee joint of the product.

　　The extrusion forming method of stainless steel tee joint originally uses emulsified liquid as filling medium to meet the requirements of energy saving and environmental protection. The stainless steel tee joint extruded by this product is easy to clean, and the emulsified liquid of filling medium in the tube can be reused, which will not pollute the stainless steel tee and the environment. In addition, a plastic film was coated on the stainless steel tee blank in advance, which effectively prevented the defects on the surface of the formed tee joint and significantly improved the processing quality of the stainless steel tee joint.
