Introduce of transmission expansion joint
The detachable double-flange transmission joint is composed of loose sleeve expansion joint, short pipe flange, power transmission screw and other components. It can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and has a certain amount of adjustment to facilitate the adjustment of the actual construction environment.
Advantages: simple and convenient installation, convenient valve installation. This product is applicable to the pipeline with flange connection on both sides, which is convenient for adjustment according to the site size during installation and maintenance. During operation, the anti-axial thrust can be transmitted to the whole pipeline.
It is suitable for transporting seawater, 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 degree C
