After the ssjb-3 gland type limit expansion joint is installed on the pipe, tighten the elastic sealing ring of the nut. Under the action of the nut gland, it relies on the mutual inclination to tighten the sealing and connecting function of the outer ring of the pipe. When the temperature changes, the pipe can freely expand and contract in the middle of the joint, when the foundation sinks, the pipe can be deflected, and ensure that there is no leakage seal, so as to play the purpose of automatic compensation.
