There are many ways to connect two seamless steel pipes together, but generally speaking, there are two major ways: one is a detachable connection, and the other is a nondetachable connection. Detachable connection refers to the removal after installation. A nondetachable connection is to connect two seamless steel pipes together forever.

The most commonly used method of nondetachable connection is welding. Various welding methods weld together two seamless steel pipes. This method costs less, but it requires a higher working environment. If the pipe is too long or the diameter is too large, it is not convenient to work after welding together.

The most commonly used detachable connections are

1、Flange connection (easy assembly and disassembly, strong versatility).

2、Union connection (Union is divided into thread type and welding type)

3、Special pipe joint connection (internal thread, external thread, and other forms).

Users can choose the specific connection mode according to their own situation, no matter which connection mode is used, it should be firm and reliable.
