In industrial installations such as petrochemical plant flue duct systems, coal chemical plant flue duct systems, thermal power plant flue duct systems, etc., compensators or expansion joints are widely used in flue ducts to play the role of thermal expansion compensation, multi-directional It plays key functions such as compensation, installation error compensation, noise reduction and shock absorption.

 

During the manufacturing process of the compensator, our company has optimized the docking form of each interface of the compensator and the sealing and heat insulation form of the soft connection part on the premise of meeting the technical requirements of the design standard compensation amount. It can also be carried out according to the compensation amount required by the user. We design and manufacture non-standard supporting compensators. In the operation and use of many project installations, the products have demonstrated excellent compensation effects and service life, and have won praise from many user units.
