Introduction of ductile iron dismantling joint

Double flange loose sleeve power delivery joint is consist of flange loose sleeve expansion joint, a connection short pipe, power delivery screw and other components, it can reduce the pressure ,thrust and blind plate force of the connector, it can also compensate the installaiton error of pipe, but double dlange loose sleeve powder delivery joint can't absorb the axial displacement.

Model introduction of ductile iron dismantling joint

The model of detachable double flange power delivery joint is VSSJAFC (CC2F), it's suitable for the pipeline which both sides are connected with the flange, when installing, adjust the installation length of the two ends of product and flange, tighten the gland bolts diagonally in trun, make them a whole, and retain a certain amount of displacement, convenient for adjusting according to the size of site in the installation and maintenance, the axial thrust can be transmitted to the whole pipeline at work.

Scope of ductile iron dismantling joint

Double flange loose sleeve power delivery joint is suitable for transporting sea water, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, the steam which temperature is not higher than 250°C, particle and powder other media etc.
