Double Flanged Loose Limited Expansion Joint

Product Description

 

Product Description

 

      The double flange limited expansion joint is composed of main parts, sealing rings, gland, telescopic short pipe and other main components. On the basis of the original performance of the loose sleeve expansion joint, a limit device is added, and a double nut is used for locking at the maximum expansion. Pipeline can be free to expand in the allowable expansion, once exceeding its maximum expansion limit, to ensure the safe operation of the pipeline, especially for vibration or a certain degree of inclination and bending in the pipeline connection.

       The material of double flange limited expansion joint is mainly Q235 carbon steel, stainless steel, cast steel, ductile iron and so on. Different materials and models are chosen for different purposes.
