Threaded expansion joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The threaded expansion joint is made of rubber double ball and metal plate movable joint by vulcanization of inner layer, reinforcing layer and outer layer. Threaded expansion joint material: Forging / Casting (round or square), surface treatment galvanized; Threaded expansion joint ball material: the inner layer is heat-resistant rubber, the outer layer is aging resistant rubber, the middle is reinforced cotton cord cloth.

Features of threaded expansion joint

Threaded expansion joint features:

1. The threaded expansion joint can reduce the noise produced by the vibration of the pipeline pump, and has strong damping capacity.

2. The threaded expansion joint is easy to install and operate, simple and flexible.

3. The threaded expansion joint is a kind of inner seamless high pressure rubber joint made of rubber soft joint. The Screw rubber joint can effectively prevent the corrosion of the inner wall of rubber soft joint caused by high temperature resistance, acid and alkali resistance and corrosion medium in oil resistant pipeline, and improve the service life.

4. After the threaded expansion joint is installed, it can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline. The Screw rubber joint is not limited by the imbalance of the pipe with the neutral flange.

Technical data of threaded expansion joint

Note: 1. The special requirements of threaded expansion joint can be customized according to the user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of threaded expansion joint can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc.

Threaded expansion joint  application

Threaded expansion joint can not only compensate axial, lateral and angular displacement, reduce noise, absorb vibration, but also threaded expansion joint has anti-corrosion performance. Threaded expansion joint also has excellent high pressure resistance, good elasticity and large displacement compensation. Moreover, the threaded expansion joint has good vibration and noise reduction performance and is easy to install. Therefore,threaded expansion joint is widely used in water supply and drainage, HVAC, fire protection, compressor, papermaking, pharmaceutical, ship, water pump, fan and other pipeline systems.
