How much do you know about high temperature resistant non-metal expansion joints?
The main material of the high-temperature non-metal expansion joint is silica gel, fiber fabric and other materials. Among them, fluorine rubber and silicone materials have good high temperature resistance and corrosion resistance.
High-temperature non-metallic expansion joint is a special product for flue gas ducts. Compared with metal expansion joints, non-metallic expansion joint has the characteristics of low cost, simple manufacture, and long cycle life. However, the material is prone to aging after being exposed to high temperature. From a long-term perspective, such as high-temperature pipelines in cement plants and steel plants, it is recommended to use stainless steel high-temperature expansion joints.
How can non-metal expansion joints realize high temperature compensation?
Non-metal expansion joints are often used in flue gas ducts and dust removal equipment, mainly to absorb the axial displacement and a small amount of radial displacement of the pipeline. Usually, a layer of PTFE cloth, two layers of non-alkali glass fiber cloth, and a layer of silicone cloth are often used for non-metallic expansion joints. Such selection is a scientific design solution proven by trial and error.
In order to better serve our customers, our company has newly introduced high-temperature resistant fluorine tape, which is mainly used for high-temperature gas pipelines.
Non-metallic flexible connections can design products with a temperature resistance of 1000℃ for you through the transformation of our company’s technology. In order to meet more technical requirements for equipment and pipelines, our company can also tailor fan expansion joints for you.
