Products Introduction

The double flanged limit expansion joint offers reliable sealing properties and is convenient for installation and maintenance. It can compensate for axial displacement in pipelines caused by thermal expansion and contraction within a certain range, transmit axial thrust and tensile forces, adjust the maximum expansion capacity, and prevent pipe connections from loosening. When the pipeline expands or contracts freely within the permitted range,the joint allows for this movement; however, once the maximum expansion limit is exceeded, it acts as a restraint to ensure the safe operation of the pipeline. It is particularly suitable for connections in piping systems with vibrations, slopes, or bends. It is widely used in fluid transportation pipelines in industries such as construction,urban water supply and drainage,wastewater treatment, petrochemicals, metallurgy, and power.
