The VSSJAFC expansion joints are functioned with pull and pres-sure resistance, excellent seal performance and easy installation. Hence it is widely used in power, metallurgy, drainage and sewage disposal to connect pump, vale and pipe etc. It also has some multi-directional displacement during pipes operation so as to release blind plate propulsion and protect pipes. However, force- transferring joints shall be used on the pipe corner and pump exit, because, the joints can transfer blind plate propulsion from pump start to pump and pipe through force- transferring bolt and prevent pull to centralize close to pipe or pipe or damage equipment by impact force.
It  has the following applicable scopes:

1. The metal product is functioned with pull and pressure resistance.
2. The metal product is excellent seal performance and easy installation.
3. It is widely used in power, metallurgy, drainage and sewage disposal to connect pump, valve and pipe, etc.
4. It also has some multi-directional displacement.
5. It makes it easy to install and maintain pipes.
