Bushing, professionally known as reducing joint, is generally processed after cutting and forging with hexagonal bar. There are many types of threads used. It is used to connect internal and external threaded fittings of two pipes with different diameters, and plays an irreplaceable role in pipe connection.
When the diameter of the water pipe needs to be reduced, the bushing will be used. For example, DN15 water pipe should be reduced to DN20 water pipe. The DN15 water pipe is an outer wire pipe, which is connected to one end of the inner wire of the bushing. The water pipe of DN20 is an inner wire pipe, which is connected to one end of the outer wire of the bushing. If the DN20 water pipe is an outer wire pipe, an inner wire shrinkage joint can be connected between the DN20 outer wire pipe and the bushing. The threaded connection can be easily connected with any water appliance and valve meter. Industry. Life is often used to change the size of pipe diameter by internal and external threads (teeth) of connecting pipe.
