NPT, PT, G pipe thread

The nominal diameter refers to the diameter of the pipe connected, and the diameter of the thread is obviously larger than the nominal diameter. 1/4, 1/2, 1/8 are the nominal diameters of inch screw threads, in inches. All screw thread interfaces of our company can be customized according to user requirements.
NPT, PT, G are all pipe threads.
NPT is the abbreviation of National (American) Pipe Thread, which belongs to the 60 degree cone pipe thread of the American Standard and is used in North America. The national standard can refer to the GB/T12716-1991 vacuum solenoid valve.
PT is the abbreviation of Pipe Thread. It is a 55 degree sealed conical pipe thread. It belongs to the Wyeth thread family. It is used in Europe and the Commonwealth countries. It is commonly used in the water and gas pipe industry. The taper stipulates that GB/T7306-2000 can be consulted for the national standard of 1:16..
G is a 55 degree non thread sealing pipe thread. It belongs to the family of Wyeth thread. Symbol G represents cylinder thread. The national standard can refer to GB/T7307-2001 high voltage solenoid valve.
In addition, the 1/4, 1/2, and 1/8 marks in the thread refer to the diameter of the thread, the unit is inch. The inner person usually calls the thread size, one inch equal to 8, the 1/4 inch 2, and so on.
G is the general designation of pipe threads (Guan). The division of 55 and 60 degrees is functional, commonly known as pipe circles. That is, the thread is made from a cylindrical surface.
ZG is commonly known as a cone, that is, thread is processed by a circular cone. The general pipe fittings are all like this. The national standard is marked as Rc.
The metric thread is represented by the pitch of the screw. The United States and English threads are represented by the number of threaded teeth per inch. This is their biggest difference. The metric thread is the 60 degree equilateral tooth, the British thread is the isosceles 55 degree tooth type and the aesthetic thread is 60 degrees.
Metric unit for metric thread, British and American screw thread. Solenoid valve
Pipe thread is mainly used for pipeline connection, its internal and external threads are closely matched, and there are two kinds of straight pipe and cone pipe.
