　　What are the basic types of threaded pipe connection?

　　Bolt connection

　　Between the bolt and the hole, there is gap between the bolt and the hole. The processing precision of the rod and the hole is low. When used to tighten the nut, can bearing axial and transverse loads. Ordinary bolt connection assembly and disassembly is convenient, the most widely used. There is no gap between the bolt hole and the bolt hole, and the processing precision of the rod and the hole is high, and can bear the lateral load and the positioning effect.

　　Double headed stud connection.

　　Lo Zhu are threaded at both ends, one end to tie in with the nut, one end and is connected with a, one end and is connected with a, this connection is to be connected one thick and often dismantled occasions, demolition, just unscrew the nut.

　　Screw connection

　　The screw is not fit to have the nut, the screw is directly connected to the threaded hole in the connecting piece, the structure is simple, but is not often removed, so as not to damage the hole thread.

　　The locking screw connection

　　Will be tightly fixed screw is screwed into a connection is a pit in, and at the end of its top in another is connected piece of clothing surface or pre made in the pits, two parts are relatively fixed. This connection is usually used to transfer the power of the parts and the rotating shaft together, to prevent the relative displacement of the two parts.
