Advantages of non-metallic compensators
The non-metallic compensator can effectively absorb not only pipeline expansion but also pipeline vibration, and can be used for equipment interfaces that need vibration isolation. In the calculation and selection, in addition to the requirement of working temperature, the superposition of thermal displacement of pipeline system and thermal displacement of equipment interface should be paid attention to, which can be used as the basis of type selection. In fact, the product is mainly made of stainless steel material or material according to user requirements. It has excellent flexibility, corrosion resistance, high temperature resistance (-235℃ ~450℃), high pressure resistance (up to 32MPa), and can be connected in any direction in the pipeline. Now it is mainly used for temperature compensation and vibration absorption, noise reduction, changing the direction of media transport, eliminating mechanical displacement between pipes or between pipes and equipment, etc.
Non-metallic compensators are suitable for fittings particularly suitable for various pumps and valves that are flexible with displacement and vibration. Now it can carry out axial, transverse and angular compensation, and has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise reduction and vibration reduction, etc. It is especially suitable for hot air ducts and flue gas ducts. If the non-metallic compensator burns through during operation, it should be dealt with in time. For the case of wide expansion joints, serious cracking of castables and short time, ceramic fibers can be filled in the expansion joints, and high-temperature hot plugging glue can be applied layer by layer. On the one hand, the combination between the ceramic fiber and the expansion joint can be strengthened; on the other hand, the cracked castable can be temporarily blocked and replaced after shutdown. In short, with a non-metallic compensator can compensate in multiple directions, which is much better than a metal compensator that can only compensate in one direction. The selected fluoroplastics and silicone materials have good high temperature resistance and corrosion resistance. Overall, it is lightweight, simple in construction, and easy to install and repair. Since systematic errors are inevitable during pipe connection, installation errors can be better compensated. At present, with a relatively perfect production and installation system, the fiber compensator can guarantee no leakage.
