Product introduction：

SSJB(AY) gland type loose sleeve expansion joint The product is suitable for both sides and pipe flange connection, do not need welding, reasonable structure, good sealing performance, quick and convenient installation. On the basis of the original performance of the gland type loose sleeve expansion joint, a limiting device is added, and double nuts are used to lock the maximum expansion of the gland type loose sleeve expansion joint. In this way, the pipeline can be freely expanded in the allowed expansion amount. Once the maximum expansion amount of the gland type loose sleeve expansion joint is exceeded, the limit will be played, so as to effectively ensure the operation of the gland type loose sleeve expansion joint pipeline, especially suitable for vibration or a certain inclination and the selection of the pipeline in the corner.

Product advantage：

SSJB(AY) gland type loose sleeve expansion joint advantages: easy to install, no welding. 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. SSJB(AY) capping type loose jacket expansion joint is suitable for conveying sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, temperature is not higher than 250 degrees steam and granular powder and other media.

product feature：

1, can realize the pipeline line axial displacement compensation. And from the simple structure, its expansion will be twice as large as the loose sleeve expansion joint, with greater axial compensation.

2. Reduce vibration and noise to a certain extent and protect the pipeline.

3, simple structure, convenient installation, easy maintenance and maintenance.
