Concentric Reduced Rubber Joint High Temperature Resistance Expansion Joint for Pipe
Expansion joint for pipe alternatively referred to as a flexible coupling with concentric varying diameters, serves as a multifaceted element in piping systems, facilitating the connection of pipes of disparate sizes while preserving a centered alignment. By merging the adaptability of rubber with the accuracy of a concentric reducer, it emerges as a preferred option for a diverse array of industrial and commercial undertakings. This unique blend of flexibility and precision ensures seamless integration and efficient performance across various piping networks.
Characteristics of Concentric Reducer Expansion Joint for Pipe
1. Small size, light weight, flexibility, convenient installation and maintenance
2. It reduces the transmission of structural noise and has strong shock absorption.
3. It has the ability of horizontal displacement, axial displacement and angular displacement, and has the characteristics of flange reconstruction and non parallelism.
4. Prevent the corrosion of the inner wall of concentric reducing rubber joints in high temperature, acid-base and oil resistant pipelines and prolong their service life.
