The pipe repair straub coupling manufacturer tells you that the union is a connector that is easy to disassemble. It contains a rubber gasket, and the direct connector is equivalent to a sleeve connection.

1. The manufacturer of pipe repair straub coupling tells you that the direct head is the pipe fitting in the pipeline. If the pipeline exceeds the length of a single pipe (such as 4m, 6m, etc.), it will be used directly. In order to repair and disassemble the valve, it is necessary to add a live connection.
The manufacturer of pipe repair straub coupling tells you that it is purely to extend the pipe to go straight forward, that is, the pipe fitting used to connect when the length of the straight pipe exceeds the length of a single pipe on site.
2. Union, as the name implies. It is a kind of connector and can be easily disassembled. The manufacturer of pipe repair straub coupling tells you that it is often used for household installation of pipes. Generally used on threaded pipes. Therefore, it is generally used on pipes with small diameters. Larger pipe diameters are generally connected by flanges, etc., which are also easy to disassemble.
The manufacturer of pipe repair straub coupling tells you that there are only threads and sockets for unions, and even socketed unions can be unscrewed with threads. With a live joint, there is no need to screw the pipe. If there is no threaded connection of the live joint, the pipe must be moved to disconnect the connection.
Pipe connection: The pipe repair straub coupling manufacturer tells you that the pipe connection refers to the connection of the processed and prefabricated pipe sections into a complete system according to the requirements of the design drawings. During construction, different connection methods should be selected according to the material of the pipe used. The pipe repair straub coupling manufacturer tells you that ordinary steel pipes have threaded connection, flange connection, welding connection, socket connection, pipe bonding connection and other methods.
