Tungsten carbide thin-shank-machine-tap’s features and precision: fine shank machine taps rotate clockwise direction, the precision is divided into three tolerance levels. That is: H1, H2, H3.

H1 level: suitable for processing thread 4H, 5H's;

H2 grade: suitable for processing 5G, the internal thread 6H;

H3 level: suitable for processing 6G, internal thread 7H, 7G's.

Tungsten Carbide 60-tapered-pipe-thread’s Feature

Details: Category: Tungsten Information; Published on Monday, 21 July 2014 18:46; Hits: 592

Tungsten carbide 60-cylindrical-pipe-thread relies entirely on their own to form a seal between the threads without any sealing medium. Dry seal pipe thread stipulates a more stringent tolerances, precision metal thread , only on special occasions.

Tungsten carbide 60-cylindrical-pipe-thread has high strength and good sealing, the use of threads on the brittle material having a thin cross-section can reduce breakage. Tungsten carbide 60-cylindrical-pipe-thread between internal and external thread with no gaps, isan interference fit. There is transition cooperation with Tungsten carbide 60-cylindrical-pipe-thread. It is mainly used for high temperature and pressure on the sealing demanding places.

Tungsten Carbide 60-tapered-pipe-thread Introduction

Details: Category: Tungsten Information; Published on Monday, 21 July 2014 18:44; Hits: 597

Tungsten carbide 60-cylindrical-pipe-thread, is also known as NPTF. US-made dry seal tapered pipe thread, National (American) Pipe Thread abbreviation belonging to the American standard 60-degree taper pipe thread for the North American region. Its tooth type angle of 60 degrees, cone degrees 1:16 taper limit deviation of -0.005 ~ +0.005 mm / mm NPTF thread of one and two two levels.

For the level, to test the height level of the thread. When a standard test can be omitted NPTF male thread, to ring simultaneously with the L1 and L2 ring; within the detection tungsten carbide 60-cylindrical-pipe-thread, we should use with the L1 plug and L3 plug at the same time.

Tungsten Carbide 55-tapered-pipe-thread-tap’s Circumstance

In the sealing mechanism, tungsten carbide 55-tapered-pipe-thread-tap, with its unique sealing effect, are widely used. But in machining, the parameters listed in the various manuals, without exception, to the base surface is given in a standard size.

This abstract dimension, both in the actual processing is difficult to measure and difficult to control, resulting in the processing of the thread will vary and reduces interchangeability. Tungsten carbide 55-tapered-pipe-thread-tap are in the assembly, not the song is tight, not difficult to install, but also seriously affect the sealing performance. By now translated, with precise, habitual use of lip dimension to replace the complex base size, not only more convenient processing, and significant progress in tungsten carbide 55-tapered-pipe-thread.
