A brief introduction of nonmetallic fabric skins: Fabric compensator skin, also known as non-metal skin, non-metal compensator skin, is an indispensable part of non-metal compensator. Non-metallic fabric skin is mainly made of multi-layer soft material, which has many advantages, such as wide temperature range, high pressure, strong corrosion resistance, good flame retardancy, sound absorption and shock absorption, good flexibility and so on. Compared with the traditional metal bellows, the outer part of the bellows is made of glass fiber fabric, which is composed of silicone rubber cloth or fluororubber cloth with good performance and alkali-free glass fiber cloth, etc. It is a kind of high strength sealing composite material. It avoids the hard force transmission of connection transmission, eliminates the vibration of pipeline, solves the compensation problem of fan thermal expansion and contraction and the unavoidable displacement of metal parts. It can also play a protective role in accidents. And it is far superior to metal bellows in transportation, installation, cost and maintenance. The characteristics of non-metallic fabric skin: The non-metallic fabric skin is located in the middle of the non-metallic Compensator and is connected by a soft fabric coated cloth filled with insulating cotton. The skin is made of fiberglass fabric and has excellent flexibility and transverse dislocation function. Insulating cotton isolates the high temperature of the medium in the pipeline from the skin to form a temperature gradient from inside to outside, which reduces the high temperature pressure on the skin. Due to the rapid development of modern science and technology, the comprehensive properties of non-metallic skin materials, such as high temperature resistance, acid-alkali resistance and chemical stability, have far exceeded that of metal materials. Non-metallic expansion joints have been agreed to replace metal expansion joints in many fields. Under the same size, the compensation function of nonmetallic fabric skin is much greater than that of metal expansion joint. Especially for the compensation function of transverse displacement. The material of non-metal compensator skin not only has good heat resistance, but also has good acid and alkali resistance. Use of non-metallic fabric skins: It is widely used in the entrances and exits of flue gas desulfurization, dust removal equipment, air heating, flow-assisted blast and other equipment in iron and steel plants, smelters, petrochemical plants, thermal power plants, and atomic power plants. Its performance and Jacob's superiority to metal compensators have won the unanimous praise of users, and has been vigorously promoted. Over the past few years, our Gongyi Hongsheng Pipeline Equipment Co., Ltd. has continuously developed new products, improved product quality, done a lot of research and experiments, put forward a new product structure, greatly improved the performance of the products, and won the praise of the vast number of users. If special specifications of products are needed, they can be designed and manufactured according to user's requirements. And sincerely hope that new and old customers, design units recommend the use of our company's products.
