● 1,Steel expansion joint,Dismantling joint,Dismantling connector,Dismantling expansion joint

● 2,Double flange expansion joint is applicable to: petroleum, chemical, smelting, ships, power plants, water supply and drainage, transmission and exhaust pipelines, etc. It is used to transport sea water, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 ℃.

Double flange expansion joint is also called double flange expansion joint loose sleeve expansion joint, limit expansion joint, expansion joint. The double flange loose sleeve limit expansion joint adds a limit device on the basis of the original performance of the loose sleeve expansion joint, and locks the nut according to the expansion amount. The pipeline can expand and contract freely in the allowable expansion and contraction amount. Once the maximum expansion and contraction amount is exceeded, the limit will be set to ensure the safe operation of the pipeline. It is especially suitable for the connection in the pipeline with vibration or a certain slope and turn.




The expansion joint series products are metal products, which have high tensile and compressive strength, superior soft sealing performance, convenient installation and disassembly and other functions. They are widely used in electric power, metallurgy, chemical industry, water supply and drainage, sewage treatment and other industries, mainly for the connection of pumps between valves and pipes. The double flange limit expansion joint has a certain multi-directional displacement effect in the pipeline operation, and plays an important expansion compensation role in the pipeline operation due to thermal expansion and contraction, crustal subsidence and stress. Therefore, the expansion joint can relieve the blind plate thrust in the pipeline operation, and play a certain role in protecting the pipeline, especially providing great convenience for the installation and maintenance of the pipeline. However, at the outlet of water pump and at the corner of the pipeline, in the connection of sliding pipeline without fixed buttress, infinite buttress and the directional limit of buttress support, the power transfer joint limit expansion device (expansion joint) and anti pull off limit rubber joint shall be used, because the power transfer joint can transmit the thrust of blind plate when starting the pump to the pump and various parts of the pipeline through the power transfer bolt (i.e. full thread bolt), so as to avoid the thrust concentrated at the corner of the pipeline or near the pump, Equipment is damaged by impact force.
