Pipe thread taps are used to tap internal pipe threads on pipes, pipeline accessories and general parts. There are G series and Rp series cylindrical pipe thread taps and Re and NPT series tapered pipe thread taps. G is a 55°unsealed cylindrical pipe thread feature code, with cylindrical internal and external threads (court fitting, only for mechanical connection, no sealing); Rp is inch sealed cylindrical internal thread (interference fit, for mechanical connection and Sealing function); Re is the characteristic code of the inch sealing cone internal thread; NPT is the cone sealing pipe thread with a tooth angle of 60°.
The working method of the pipe thread tap: First, the cutting cone part cuts the person, and then the tapered thread part gradually enters the cutting. At this time, the cutting torque gradually increases. When the cutting is completed, the tap is increased to the maximum before reversing and retracting.
Due to the thin cutting layer, the unit cutting force and torque at work are much larger than that of cylindrical threads, and the processing of small diameter taper threaded holes is inseparable from the processing method of tap tapping, so taper thread taps are often used to process smaller diameters. 2″ taper thread.
Feature:
1.Ideal for rethreading fasteners and fastener holes for auto and machinery repair.
2.Precision milled set tap and die set for cutting raw material or repair existing threads, remove screws and more function.
3.It can improve the efficiency of processing thread, a necessary tool for hand tapping operation.
4.Taps are used for drilling internal threads. Ideal for threading pipe fittings.
5.Mainly used for all kinds of inner thread machining of the pipe fittings, coupling parts.
