PINYI New Materials has over 10 years of experience in manufacturing Fabric expansion joints. We are skilled at selecting materials and ingredients based on different usage environments. You only need to provide accurate working conditions information, and we can tailor a suitable product for you, ensuring excellent quality and stable delivery, and fully meeting your usage needs.
Fabric expansion joint is made by sewing multiple layers of high-performance materials. It can be used in power plant flue ducts, boiler flue duct inlet and outlet, dust prevention vents in cement plants, and waste-to-energy power stations, etc. It has the functions of high-temperature resistance, acid and alkali resistance, fire resistance, anti-tear, anti-aging, and sealing.
1.Suitable for high-temperature working conditions
If you only need to work in high-temperature environments, like in a cement factory,you can choose high temperature fabric expansion joints with silicone. Its temperature resistance range can be within 1000℃, and it can resist aging, seal, shockproof and be wear-resistant.
2. Suitable for high-temperature and acid-base resistant conditions
If your working environment contains acidic gases and the temperature is very high, you can choose the main type of fluorine(FKM) rubber expansion jiont.
3.Suitable for working conditions with strong acidity and low temperature
If the working environment you require is one where the gas has strong corrosiveness, such as sulfur dioxide, and there is also water accumulation, then you can choose this fluorine-based(FKM) material expansion joint. Its water resistance and acid-base resistance can meet your desired requirements.
If none of the above conditions can meet your requirements, PINYI New Materials will tailor a suitable fabric expansion joint specifically for your needs.
1.Silicone rubber coated fiberglass fabric :
It is made by using high-strength glass fiber cloth resistant to high temperatures up to 550℃ as the base fabric and high-performance organic silicone rubber. It is compounded through special processes by coating or pressing. It is a new type of high-performance and multi-purpose composite material product. Its temperature resistance can reach 280℃. Silicone rubber coated fiberglass fabric can play the roles of fire prevention, high-temperature resistance, sealing, wind pressure resistance and anti-aging within the fabric expansion joint.
2.FKM rubber coated fiberglass fabric :
It is made by combining a high-strength glass fiber base cloth with a fluorine-containing polymer that is resistant to corrosion. It is produced through the calendering process. Its function in the fabric epansion jionts is to withstand high temperatures, resist acids and alkalis, be waterproof, resist wind pressure, and resist aging.
It is made from raw materials such as quartz sand and limestone. After being melted, it is drawn into glass fiber yarn and then woven into a fabric. It can play roles such as high-temperature resistance, anti-tear, fire prevention and insulation in fabric expansion joints.
4.PTFE cloth :
This product is made by impregnating glass fiber fabric with polytetrafluoroethylene emulsion, and then through drying and sintering processes. It endows it with the high-temperature resistance and high-strength properties of glass fiber fabric, as well as a series of excellent features such as insulation and anti-sticking of polytetrafluoroethylene.
5.Ceramic fiber cloth :
It is made by weaving ceramic fibers (mainly aluminum silicate) with reinforcing yarns. Its long-term temperature resistance can reach 1000℃, and for short periods, it can exceed 1260℃. In the fabric epansion joint layer, it mainly plays the roles of high temperature resistance, wear resistance, high strength, and anti-pressure. It is a necessary material for high-temperature resistant products.
Fabric expansion joints are mainly used in the smoke and air ducts of thermal power plants, thermal power stations, steel mills, cement plants, etc., as well as in the desulfurization and denitrification pipelines, absorption tower smoke ducts, and dust removal system devices, etc., at their entrances and exits.
What are you most concerned about when choosing fabric expansion joints? Leakage of smoke and gas, ability to withstand high temperatures, whether they are resistant to acids and alkalis, cracking and short lifespan, installation issues, and after-sales troubles? Our products are specifically designed to address these on-site problems.
1.material advantage:
PINYI New Material is carefully selected from high-quality silicone rubber and fluorine rubber raw materials. This prevents any leakage or cracking during the use of inferior materials, ensuring the long-term sealing stability of the fabric expansion joint.
2.Professional ingredients:
Since its establishment, PINYI New Materials has had over 10 years of experience in selecting raw materials for fabric expansion joints. It can make appropriate material selection for every working environment, whether it is a high-temperature environment or an environment with wear resistance, acid and alkali resistance, and water accumulation. We can make correct judgments and formulate corresponding materials.
3.Customization capability:
Our company can customize the size according to your requirements. It can be in circular, square or irregular shapes. The installation method can be either flange with flange edge or metal strip. We can make it according to your drawings.
4.Production one-stop service:
PINYI New Material has its own factory covering an area of 10,000 square meters. From the production of fabrics, cutting, manufacturing to export, the entire process is integrated. We can ensure stable delivery schedules and handle both large orders and urgent orders with ease.
5.Industry application experience:
Applicable scenarios include: power plants, boiler factories, cement plants, waste incinerators, steel mills, etc. (for flue and duct systems).
6.Price advantage:
PINYI New Material has its own composite material factory. The raw materials and base materials are directly sourced from the original suppliers, eliminating the middleman’s markup. We adhere to matching materials based on the working conditions, avoiding blind over-provisioning and also not cutting corners by misusing materials. At the same quality standard, our quotations are more realistic. Although the initial purchase price seems similar, the life of the fabric expansion joint is longer, significantly reducing hidden expenses such as equipment replacement during downtime, on-site emergency repairs, and environmental rectification. The overall cost of the project throughout its entire life cycle is lower.
