Product Description

There are two types of union joints: threaded connection and socket welding connection. Socket welding is to insert the steel pipe into the socket for welding. Therefore, it is called "socket union". Threaded connection is to screw the steel pipe into the screw hole. The connection is therefore called a "threaded union. The union is also called union or union. The English word is union. It is a common pipe connection that can be easily installed and removed. The union is composed of three parts, a special one. An octagonal nut or a round nut, and two special threaded joints, the threaded joint is used to connect the two ends of the pipe, the middle nut is equivalent to a pipe hoop to connect the two ends of the pipe, so that it can play without removing the pipe The separation of the two pipes is convenient for maintenance, so it is widely used in various pipe fittings, it will be disassembled and repaired with the pipeline, if there is no need for live connection, once the problem occurs, it must be completely dismantled. The nut, the cloud head, and the flat joint are composed of three parts. When assembling, the first step we need to do is to place the flat joint in the nut, and then install a special washer in the groove of the cloud head, and finally screw the cloud head in Inside the nut, such a complete set of union fittings is assembled. After the assembly is completed, it needs to be connected to the pipe of the pipeline system by welding. The welding requires the operator to have excellent technology to avoid loopholes during welding Or welding seams, inconvenience to the subsequent work.
