SSJB-3 type gland type limit loose sleeve expansion joint

The model of the gland limit loose sleeve expansion joint is SSJB-3 (GB/T12465-1999) or BY (GB/T12465-2002). The gland limit expansion joint is composed of a loose sleeve expansion joint and two limit short tubes. The gland limit expansion joint can prevent leakage and damage of the compensating joint caused by excessive displacement of the pipeline. The gland limit expansion joint is mainly used for loose connections of pipelines that absorb axial displacement and withstand axial pressure thrust within the allowable displacement range.

Advantages of gland limit expansion joint: The gland limit expansion joint has a large expansion capacity, simple and convenient installation, long service life (up to 10-30 years), and easy maintenance.

The characteristics of the gland limit expansion joint: The two sides of the gland limit expansion joint pipeline are connected by welding.

Installation method of gland type limit expansion joint: Both sides of the gland limit expansion joint are welded to the pipeline. When installing the gland limit expansion joint, loosen the gland nut, adjust to the installation length, and weld the short pipes at both ends to the pipeline. Finally, tighten the nut evenly using diagonal method and adjust the anti loosening nut.
