1. Since 1988, Top 3 manufacturer of expansion joint in China;
2. The Main Drafting Committee of National Standard for Universal Compensator;
3. Qualified Supplier for Nuclear Power Plant;
4. ISO9001: 2008 and ISO14001: 2004 Certified.

Product performance of metal expansion joint:

1 Expansion Joint Stainless Steel (they are also called compensators) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines.
2 They consist of one or more metal bellows, connectors at both ends, and tie rods that depend on the application. They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints.
3 Expansion Joins  are elastic vessels that can be compressed when pressure is applied to the outside of the vessel, or extended under vacuum. When the pressure or vacuum is released, the bellows will return to its original shape (provided the material has not been stressed past its yield strength).

Features of Expansion Joint Stainless Steel
1. Reasonable structure, good elasticity, large range of compensation pipeline and little counterforce to the brackets of pipeline.
2. Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket.
3. The displacement can be deflected to prevent damagment caused by subsidence of connected brackets and equipment base. It can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance.
4. Good resistance to milling, heat, aging and corrosiveness and long service life.
5. Little resistance and little weight. Each performance is better than the compensation device of other materials.
6. The temperature range of media is wide:-40-300 Celsius degree

Application Range of Metal Dismantling Joint

1 The Metal Dismantling Joint 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.
