1. The outer wire is direct: the screw is on the outside, opposite to the inner wire bend.
2, the outer wire live joint: easy to install and disassemble the common pipe connector, mainly consists of nut, cloud head, flat three parts.
Two, the way is different
1. Direct outer wire: the special elbow pushing machine, core die and heating device are used to make the blank set on the mold move forward under the push of the pushing machine, and the process of heating, expanding and bending and forming in the movement.
2, the outer wire loose: there are nuts, cloud head, flat three parts. Pipe connectors machined by die forging of round steel or steel ingot are connected in the form of plug welding and threaded connection. Plug welding is to insert steel pipes into the socket for welding.
Three, different characteristics
1, the outer wire direct: forming process is hot push, stamping, extrusion, etc.
2, outer wire flexible: applied to different caliber pipe, can also be used for water meters, valves. Due to the use of spigot structure, the pipe joint reduces the cost, installation, use, maintenance is extremely convenient, but also has extremely high leak-proof ability
