The processing process and precautions of the internal thread of stainless steel pipe fittings
Stainless steel pipe fittings are a kind of pipe fittings, which are made of stainless steel. The internal threads of the stainless steel pipe fittings are mainly tapped by taps, which can improve the viscosity of the stainless steel pipe fittings. However, if it is not handled properly, during the tap tapping process, it will be prone to cutting and scratching the thread of the workpiece or the tap chipping. This will not only affect the processing efficiency, but also cause damage to the stainless steel pipe fittings and affect the use of the stainless steel pipe fittings. Life and performance.
(1) Choose a better tap material. Adding special alloy elements to ordinary high-speed tool steel can significantly improve the wear resistance and toughness of the tap.
(2) Coating titanium nitride coating on the surface of the tap thread can significantly improve the wear resistance, heat resistance and lubricity of the tap.
