Charactristics for Fabric Expansion Joints

news

Our company (Shandong Hesper Rubber Plastic Co., Ltd.) makes various of expansion joints: metal expansion joints and non-metallic expansion joints. For our non-metallic expansion joints, we have fabric expansion joints and rubber expansion joints(rubber soft joints). Here let’s talk about fabric expansion joints.

The elastic elements which make up the working body of the fabric expansion joints are non-metallic materials, usually fabrics. There is also a rubber material, which can replace fabrics in various working conditions but it cannot meet the conditions of use under ultra-high temperature (above 400℃).

Features of fabric expansion joints:

⑴Can compensate for multi-dimensional directions. Various forms, larger amount of compensation, longer life;

(2) Can effectively compensate or eliminate installation errors.

(3) Low stiffness and small elastic reaction force.

⑷The applicable temperature range is high and the corrosion resistance is good.

⑸ Can effectively isolate vibration and reduce noise.

In addition to the above features, it has good sealing performance, high pressure resistance, high strength, and can resist gas containing mist and a small amount of liquid. The use of special rubber can achieve oil resistance, acid and alkali resistance, aging resistance and other effects.

Fabric expansion joints also has good comprehensive performance, it can be widely used in many engineering fields. HESPER fabric expansion joints usually used for ventilation, dust,smoke exhaust and air conditioning insulation pipes and equipment with low working pressure.

In the piping system, if there are thermal stress caused by temperature change, vibration of equipment, local stress generated by fixed support, and stress generated by system installation deviation, rigid connection will inevitably lead to the weakest part of the piping system. deformed or destroyed. If a flexible fabric expansion joints is used, such damage can be avoided.
