What is the function of double flange limit expansion joint?

Flange expansion joints are new products used to connect pumps, valves, pipes and other equipment to pipelines. They are connected by full bolts to make them into a single unit with a certain displacement for easy installation. They can withstand the axial pressure of the pipeline. In this way, they can be adjusted to the size of the equipment on site when repairing the equipment. Work not only improves the efficiency, but also has a certain maintenance effect on pumps, valves and other pipeline equipment. Double flange limit expansion joint is a successful double flange limit elastomer based on the flange type elastomer, compared to the usual double flange limit elastomer has the feature of large offset, after the offset exceeds the scale promised by the equipment, the limit equipment will work to restrain some of the casing of the elastic joint to some of the body, and will not continue to offset the displacement so as to prevent the casing from being pulled out of the body.
 
Compared with the usual elastic joint on the pipeline and valve maintenance more powerful, will not be in operation to present the phenomenon of leakage, so double flange limit expansion joint on the pipeline with valve fittings, valve repair time disassembly and lifting with double flange limit expansion joint will be more convenient. Double flange limit expansion joint is mainly used in large electric power engineering pipeline, pipeline with valve and pump and some other pipelines that need to offset.
