Product advantage：

SSJB-3(BY) gland type limit expansion joint advantages: large expansion, long service life (service life up to 10-30 years), easy maintenance. It is mainly used to absorb axial displacement and withstand axial thrust in the allowable displacement range of pipe loose sleeve connection. The sealing ring can be deformed by squeezing the gland and the body so as to ensure the high sealing of the pipeline line while compensating the axial displacement of the pipeline. And because it adopts flexible connection, it can greatly reduce the impact of vibration and noise of pipeline lines.

product feature：

1. Both sides of the pipeline are connected by welding. When the pipeline reservation distance is too long, it can increase the flexibility of product length by installing short pipe according to the actual situation, so as to adapt to the construction environment of various special lengths of pipeline reservation.

2, can effectively realize the pipeline axial displacement compensation, vibration and noise reduction and other functions.

3, convenient pipeline periodic maintenance.

4, gland type limit loose sleeve expansion joint expansion, simple and convenient installation, long service life (service life up to 10-30 years) easy maintenance.

Both sides of the gland limit expansion joint are welded with the pipe. Loosen the gland nut during installation of the gland limit expansion joint, and weld the short pipe at both ends with the pipe after adjusting to the installation length. Tighten the nut evenly with the diagonal method and adjust the anti-nut well. We look forward to working with you.
