Scope of use of rectangular expansion joints.

Rectangular expansion joints for gas turbine exhaust systems, connection parts of turbines or condensers, exhaust ports of water heaters, pressure vent fan closures, exhaust gas discharge piping, AC heat exchangers, precipitators and other steam and large piping systems.
Pressure resistance characteristics of rectangular expansion joints.
Pressure resistance is an important parameter of the performance of rectangular bellows. Metal bellows at room temperature, the static pressure that the waveform can withstand without plastic deformation, that is, the pressure resistance of the metal bellows in general, the metal bellows is working under pressure, so it bears this pressure throughout the working process without plastic deformation.
Features of rectangular expansion joint.
1. The length of the rectangular expansion joint can be cut at will according to the needs of the installation site.
2. Rectangular expansion joints are easy to bend around, so there is no need to use various elbows for transition at building turns, making installation more convenient and reducing costs.
3. The surface of the rectangular expansion joint is covered with a protective sleeve that prevents the burning of the hose, so it has good resistance to surface impact.
4. Good airtightness, each metal bellows is factory tested for its airtightness and pressure resistance before delivery.
5. Flexible connection mode, according to the needs of both non-metallic flat gasket sealing connection, can also be used metal ball cone hard sealing connection.
