How to extend the service life of the flange

　　In order to extend the service life of stainless steel flange taps and improve the quality of thread processing, where to process and produce some attention to note: in the tap wire surface coating titanium nitride coating, can significantly improve the wear resistance of the tap,DIN Stainless Steel Forged Threaded Flange heat resistance And lubricity; appropriate increase the amount of taper shovel. But should be noted that, such as the amount of shovel is too large, in the retracting when the chip is easy to plug into the cone after the angle of the phenomenon, and attack the thread finish is not good; appropriate increase the tap angle, but should be noted that, Angle is too large, in the retractable knife is likely to cause taps to chop and attack the thread polygonal.
