Fabric bellow 

Fabric bellow is used for gas flue includes: rubber compensator and fabric expansion joint.


No matter rubber bellow or fabric expansion joint, they all have fllowing characteristics:

1. Rubber has good displacement (change) a reducing repeatedly, can provide large multidimensional direction in smaller size, can better eliminate multidirectional errors caused by all kinds of piping connection.

2. Rubber has superior acoustic isolation function, can effectively reduce and eliminate boiler, fan systems such as the transmission of sound and vibration.

3. Rubber is unable to transfer loss, reduced the design process, need to increase other auxiliary facilities.

4. Rubber has high heat resistance and corrosion resistance, never rust, reduce maintenance costs.

5. Rubber has excellent air tightness and flexibility, can guarantee the transmission medium and restorable after repeated displacement without leakage.


Introduction of  silicon cloth skin air and duct fabric bellow 


Silicone cloth is also called the fabric silica gel, silica gel. After high temperature hot vulcanization made with acid and alkali resistance, abrasion resistance, high and low temperature resistance, corrosion resistance of the role is a kind of application in the chemical plants, oil refineries, port and transport, automotive, medical, industrial hot water and steam diving silicone tube, food, and other industries, especially one with high quality silicone rubber as the raw material can withstand the pressure of multi-level high voltage silicone tube. Multi-level high voltage silicon tube, described by the inner weave fabric strengthening protectionlayer, middle layer and external rubber, rubber layer, for the rubber coated fiber woven strengthening layer, weave fabric to strengthen the outside layer coated with a rubber.


Made of fabric silicone rubber has the advantages of long service life, pressure big, it can bear the pressure of 1 mpa - 10 mpa, than the service life of the ordinary high pressure rubber hose for 3 to 5 times higher; Has obvious environmental advantage. Silicone cloth is made of glass fiber cloth as base cloth, coated or calender way production and become, is a high temperature resistant, anti-corrosion, high strength glass fiber cloth, the organic silicone rubber calender or dipping and become, is a kind of high performance, multifunction composite materials of new products.

Fabric bellow performance

1. used for low temperature to 70 °C between high temperature 230 °C.

2. resistant to ozone, oxygen, light and climate ageing, field use excellent weatherability, life can be up to 10 years.

3. High insulation performance, dielectric constant of 3-3.2, the breakdown voltage 20 to 50 kv/MM.

4. Good flexibility, surface friction force is big, has good elasticity.

5. Resistance to chemical corrosion.


Fabric bellow's main purpose

1. Electrical insulation: silica gel has high electric insulation level, can withstand the high voltage load, can be made into cloth, insulation casing and other products.

2. Non-metallic compensator, silicone cloth used as flexible connecting device of pipeline, silicone rubber coated glass fiber membrane structure material as base material of the flexible expansion joint. It can solve the heat bilges cold shrink to the destruction of the pipe, silicone cloth with high resistance to high temperature, anticorrosion, aging resistance, good elasticity and flexibility, can be widely used in petroleum, chemical, cement, energy and other fields.

3. Anti-corrosion aspects: silicone rubber coated glass fiber cloth, can be used as a pipeline, the internal and external anticorrosive coating of saving, excellent anticorrosion performance, high strength, is a kind of ideal anticorrosion material.

4. Other areas: silicone rubber coated glass fiber membrane structure materials can be applied to building sealing materials, high temperature anti-corrosion conveyor belt, packaging materials, etc.

Silicone cloth can be also divided into single silica cloth and the double silica cloth, and room temperature curing and heat curing silicone cloth silicone cloth.

The most important part of Fabric bellow is bellow, it is made of composite matrials

Usually,we will use these materials:

1.outer layer: silicon rubber compund cloth or glass fiber cloth, with waterproof, and out of leakage

2.second layer: we will use heat preservation cotton

3.reinforce layer: stainless steel wire mesh

4.inner layer: silicon rubber compund cloth


If the service temperature is very high, inner layer we will use FKM(viton rubber) cloth,following picture is our semi-finished product
