Economic

1. Compared with mechanical stretch and stuffing to absorb vibration, spool type flexible rubber bellows occupies small space, weight light, save labor and low cost.

2. To the same limit ability, it doesn’t need increase pump and pipe diameter. The inner wall is smooth, which can reduce the flow resistance without damaging the pipeline body.

3. Good water tightness, no padded during installation.

4. Wide range of application: choosing different rubber compounding that makes the spool type flexible rubber bellows have the performance of heat-resistance, oil-resistance, anti-corrosion, aging-resistance, wear-resistance and ozone-resistance.

5. Wide range of heat-resistance: good material can make the product have a wide range of heat-resistance: -40~120°C

6. Long service life: more than 30 years used indoors, not less than 30 years used outdoors where the working condition is very harsh.

Displacement

Good elasticity, having a good adaptability to compression, stretch, twist, displacement in all directions, avoiding the damage of pipeline system because of thermal expansion and foundation settlement measurement.

Reducing vibration and absorbing noise

1. Rubber material can buffer vibration and reduce mechanical vibration and absorb crush noise of the liquid.

2. Intaking it between vibrating machinery and metal pipelines, which can reduce noise of 15~25 DB.

Resistance to pressure

Multilayer sphere structure is especially suitable for bearing internal pressure, explosive force. Spool type flexible rubber bellows won’t be out of shape when bearing outside pressure.

Reducibility

It can resile after compression load deflection, while metal expansion won’t resile after compression load deflection

Wide range of application

1. Suitable for indoor installation.

2. Suitable for outdoor installation.

3. Suitable for buried installation.
