2022-05-31

The non-metallic compensator is primarily composed of one layer of silicone fabric, two layers of alkali-free fiberglass fabric, and one layer of PTFE fabric. It can be seen in many different locations, indicating its significant role and wide-ranging applications. Most commonly, it is used in hot-air ducts and flue gas systems. Below is an introduction to the functions of this non-metallic compensator: Its price is lower than that of metallic compensators, yet its quality surpasses that of imported products—though its price remains comparable to imported ones. The service life of a non-metallic compensator is typically 2 to 4 times longer than that of conventional high-temperature compensators, thereby reducing overall project costs.

Many friends have asked us what materials non-metallic expansion joints are made of, and they’ve also been curious about exactly what functions these joints serve. To address these questions, let’s dive into a detailed explanation provided by our editor. If you’re also curious, why not keep reading?

Non-metallic expansion joints are primarily composed of one layer of silicone-coated fabric, two layers of alkali-free fiberglass fabric, and one layer of PTFE fabric. They can be found in many different applications. Therefore, their role is quite significant. Most commonly, they are used in hot-air ducts and flue gas systems. Below is an introduction to the functions of non-metallic expansion joints: Their price is lower than that of metallic expansion joints, yet their quality surpasses that of imported products—though their price remains comparable to imported ones. The service life of non-metallic expansion joints is typically 2 to 4 times longer than that of conventional high-temperature expansion joints, thereby reducing overall project costs. In addition to possessing excellent resistance to oxidation and corrosion by gaseous media, these joints also exhibit thermal stability. Moreover, at high temperatures, they maintain sufficient strength and heat resistance. Thus, their performance characteristics are quite diverse. It’s also important to note here that, in heating systems, non-metallic expansion joints are crucial for preventing deformation or damage to heating pipelines caused by thermal expansion or excessive temperature rise. Therefore, it’s highly recommended to install non-metallic expansion joints along pipelines to accommodate thermal expansion, thereby reducing thermal stresses on pipe walls as well as the forces exerted on valves and support structures.

Non-metallic expansion joints are coated with high-polymer materials such as silicone and fluorine, offering excellent resistance to high temperatures, corrosion, and sealing performance. They also exhibit outstanding fatigue resistance and anti-aging properties. High-quality products fully deliver on their promises of low noise and energy efficiency, effectively reducing noise and vibration from fans and other system components while significantly cutting energy consumption and operational costs. Moreover, these high-quality devices are easy to replace and do not require precise alignment, meaning no heavy lifting equipment is needed during replacement, and the process takes only a short time. During pipeline connections, installation errors are inevitable; however, fiber expansion joints can effectively compensate for and eliminate such installation inaccuracies. Additionally, they offer several other valuable features—for instance, exceptional resistance to high temperatures and corrosion. The fluoroplastic and silicone materials used in these joints provide superior performance in both high-temperature and corrosive environments. Our company’s products fully meet these advantages and excel in every aspect. You really have nothing to worry about. If you have time, feel free to visit our official website—there you’ll find contact information and an online customer service team ready to assist you.
