AY (SSJB) gland type loose sleeve expansion joint

AY (SSJB) type gland type loose sleeve expansion joint This product is suitable for connecting both sides with pipe flanges without welding, with reasonable structure, good sealing performance and quick and convenient installation. The gland type loose sleeve expansion joint is based on the original performance of the loose sleeve expansion joint, and a limit device is added, and the double nut is used to lock the large expansion amount of the gland type loose sleeve limit expansion joint. In this way, the pipeline can be freely expanded and contracted within the allowable expansion and contraction amount. Once the expansion and contraction amount of the gland-type loose-sleeve limit expansion joint is exceeded, it will act as a limit, which effectively ensures the gland-type loose-sleeve limit expansion joint. Safe operation of pipelines, especially suitable for selection in pipelines with vibration or a certain slope and in bends.

Advantages of gland type loose sleeve expansion joints:

The gland type loose sleeve expansion joint is very important for the laying of oil and gas pipelines. With the increasing importance of energy, the laying of oil and gas pipelines is also becoming more and more important. Whether the gland type loose sleeve expansion joint can be used or not is very important.

On the rubber sealing ring used in the gland type loose sleeve expansion joint, the rubber sealing ring can ensure that the double flange limit expansion joint products do not leak, and the double flange limit expansion joint products are also very good for long-term use. To ensure that the double flange limit expansion joint is made of imported rubber with rubber rings.

The limit bolts of gland-type loose sleeve expansion joints have important functions during use. The quality of the limit bolts directly affects the function of double flange limit expansion joints. Huashunying products are all made of 35# steel. , The nut is 34#, which ensures the use of bolts for expansion joint products. The characteristics of good bolts are that they are very tight. It is difficult to screw them by hand and requires a wrench. This kind of bolts are well matched bolts and can be used very well. This is the pipeline for the expansion joint product to play its own role. After the displacement of the anti-pull-off bolt exceeds the design displacement, it can play a good role in preventing the pull-off.
