Introduction to ssjb (ay) type gland type loose sleeve expansion joint
SSJB (AY) type gland type loose sleeve expansion joint is based on the original performance of the loose sleeve expansion joint, and a limit device is added. Double nuts are used to lock the large expansion amount of the gland type loose sleeve limit expansion joint. The SSJB (AY) type gland type loose sleeve expansion joint enables the pipeline to freely expand and expand within the allowable expansion amount. Once the large expansion amount of the gland type loose sleeve limit expansion joint is exceeded, the limit is activated, which effectively ensures the smooth operation of the gland type loose sleeve limit expansion joint pipeline. It is particularly suitable for selection in pipelines with vibration or a certain slope and in bends.
Usage of ssjb (ay) type gland type loose sleeve expansion joint
SSJB (AY) type gland type loose sleeve expansion joint is suitable for welding both sides of the joint with the pipe. During installation, loosen the gland nut, adjust the installation length, and then weld the short pipe at both ends with the pipe. After that, uniformly tighten the nut using the diagonal method, and adjust the anti pulling nut.
