Latest company news about What are the advantages of non-metal expansion joints?
Expansion joints can be divided into metal expansion joints and non-metallic expansion joints. Non-metallic expansion joints are also called non-metallic compensators. They are made of non-metallic materials. Dimensional changes due to temperature changes also have the effect of absorbing shock.
What are the advantages of non-metal expansion joints?
Non-metallic expansion joints can compensate for displacements in multiple directions, which is the biggest advantage of non-metallic expansion joints and is superior to metal compensators that can only be compensated in a single way.
The fiber fabric itself has the functions of sound absorption and vibration isolation, so it can effectively reduce the noise and vibration of boilers, fans, and other systems. Non-metallic expansion joints are especially suitable for smoke and air ducts.
The main material is non-metallic material, which is powerless to transmit. The use of non-metallic expansion joints can simplify engineering design, reduce construction costs, and facilitate installation without using large supports.
The application of non-metal expansion joints is becoming more and more extensive, and production technology is constantly improving. There is a relatively complete production and assembly system, which can ensure no leakage, and the price of non-metal expansion joints is lower than that of metal expansion joints, and the cost performance is still very high.
