What are the connection methods of seamless steel tubes?

1. Compression type: the piping is inserted into the pipe mouth of the pipe, fastened by a nut, and the sleeve at the mouth of the pipe is compressed by a sealing ring with a spiral force, which acts as a seal to complete the connection of the pipe.

2. Welding type: The end of the pipe is processed with a groove, and the pipe is welded manually or automatically.

3. Flange type: The flange and the piping are welded in a circular argon arc, and fastened with a clip or a bolt, so that the gasket between the flanges can seal and complete the piping connection.

4. Clamping type: Insert the pipe into the pipe and press the pipe wall into a hexagon with a special installation tool, and the internal sealing ring also changes into a hexagon.

5. Conical thread type: that is, the external thread and piping are used for annular argon arc welding, and the internally threaded pipe fittings are sealed with tapered threads to complete the piping connection.
