The double flange limited expansion joint (model VSSJA-2 or B2F) is composed of main components such as the body, sealing ring, gland, and expansion short pipe. Based on the original performance of the loose sleeve expansion joint, a limit device is added, locked with double nuts at the maximum expansion position. The pipeline can expand and contract freely within the allowable expansion range; once the maximum expansion is exceeded, the limit function is activated to ensure the safe operation of the pipeline. It is especially suitable for connecting pipelines with vibration, a certain slope, or bends.
