Features and Applications of Non-Metallic Compensators
Release time:
Jan 06,2021
Due to their inherent flexibility, non-metallic expansion joints can compensate for thermal expansion and other deformations between equipment and pipelines, as well as provide seismic resistance, vibration damping, reduce the thrust exerted by pipelines on equipment, and accommodate uneven settlement of tank foundations. Non-metallic expansion joints are inherently sealed, making them widely applicable in fields such as chemical engineering, oil refining, power generation, light industry, nuclear energy, metallurgy, machinery, instrumentation, shipbuilding, aerospace, and others. Given the extensive use of power and thermal pipelines across various industrial and civil sectors, the demand for non-metallic expansion joints is extremely high.
Due to its inherent flexibility, Non-metallic compensator It can compensate for thermal expansion and other deformations between equipment and pipelines, provide seismic resistance and vibration damping, reduce the thrust exerted by pipelines on equipment, and accommodate uneven settlement of tank foundations. Since non-metallic expansion joints are inherently sealed, they can be widely used in fields such as chemical engineering, oil refining, power generation, light industry, atomic energy, metallurgy, machinery, instrumentation, shipbuilding, aerospace, and more. Since power pipelines and thermal pipelines are widely used in various industrial and civil applications, therefore... Non-metallic compensator The demand is very high. In recent years, many large and medium-sized cities have been constructing a large number of residential buildings. From the perspective of energy conservation and pollution prevention, centralized heating and urban district heating should be vigorously promoted; therefore, heating pipelines are indispensable. In the thermal renovation of existing cities, a troublesome issue is that it’s difficult to route heating pipelines, especially since square expansion joints, with their large footprint, are particularly challenging to install. At this point, the non-metallic compensator, thanks to its compact structure, can fully leverage its unique characteristics.
I. Fiber Material Non-metallic compensator The main features are as follows:
1. Compensation for thermal expansion: It can compensate in multiple directions, which is far superior to metal expansion joints that can only compensate in a single direction.
2. To compensate for installation errors—systematic errors are inevitable during pipe connection—fiber compensators can more effectively eliminate these installation errors.
3. Seismic and Vibration Isolation: Fiber fabrics and thermal insulation cotton possess sound-absorbing and vibration-isolating properties, effectively reducing noise and vibration from systems such as boilers and fans.
4. No reaction force: The main material is fiber fabric, which does not transmit any forces. Using fiber compensators can simplify the design, eliminate the need for large supports, and significantly save on materials and labor.
5. Excellent high-temperature and corrosion resistance; the selected fluoroplastics and silicone materials exhibit outstanding high-temperature and corrosion resistance.
6. Good air tightness; with a relatively complete production and assembly system, the fiber compensator can ensure zero leakage.
7. Lightweight, simple structure, and easy to install and maintain.
8. The price is lower than that of metal compensators, and the quality is superior to imported products—ranging from 1/2 to 1/5 of the price of imported products.
II. Rubber Material Non-metallic compensator Features
In addition to the above advantages, it also features:
1. Excellent shock absorption performance
2. Excellent sealing performance—features a large flange that eliminates the need for gaskets, allowing for direct installation and cost savings.
3. Long service life.
