NPTF螺纹作为干密封螺纹，其牙型精度比NPT螺纹高，旋合时不用任何填料，完全依靠螺纹自身形成密封，螺纹间无任何密封介质，很适合用于高温高压的场合。由于其精度很高，所以必须要掌握好其加工性能和正确的检测方法。本文就这NPTF螺纹的参数、加工方法、检验方法展开讨论。

NPTF threads as dry sealing thread, its precision is higher than the NPT thread tooth type, spin right without any pack-ing, depend entirely on the thread form sealing itself, without any sealing medium between thread. Very suitable for the occasion of high temperature and high pressure. Because of its high precision, so must grasp its processing performance and accurate testing method. In this paper, the parameters of the NPTF threads, the processing method, testing method is discussed.
