The most reliable manufacture of expansion joints
1 More than 24 years experience of manufacture of expansion joint;
2 The appointed enterprise by the former chemical industry ministry.
3 The industry standard drafting unit of expansion joint.
4 Since 1988, top 3 manufacturer of mechanical coupling in China

Product Performance

1. VSSJAF expansion joints provide adjustability to equipment installations by combining a Flanged Coupling Adapter and a Flanged Spigot into one assembly.
2. VSSJAF expansion joints applications include valve, pump, meter and other flanged fitting installations.
3. Longitudinal adjustment is provided by the telescoping action of the Spigot inside the Flanged Coupling Adapter.
4. When final installation position is achieved, the bolting procedure for the Flanged Coupling Adapter and the Flanged Spigot can be completed.

Applicable Scope

1 The metal product is functioned with pull and pressure resistance and excellent seal performance and easy installation. Hence it is widely used in power, metallurgy, drainage and sewage disposal to connect pump, valve and pipe, etc.
2 It also has some multi-directional displacement during pipes' operation so as to release blind plate propulsion and protect pipes, especially it makes it easy to install and maintain pipes.
3 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 pump or damage equipment by impact force. Other joints can be selected freely for other positions. Our tenet: your trust is our honor and will manufacture high-quality products for you.
