What are the characteristics of double flange expansion joint

Double flange expansion joint is composed of loose sleeve expansion joint, short pipe flange, force transfer screw and other components. It can transfer the pressure and thrust of the connected parts (blind plate force) and compensate the installation error of the pipeline, and can not absorb the axial displacement. It is mainly used for loose sleeve connection of pumps, valves and other accessories.

Product material: Q235, QT400-15, QT450-10.

Installation method: it is applicable to the pipeline with flange connection on both sides. During installation, adjust the installation length between both ends of the product and the flange, raise funds diagonally and tighten the gland bolts evenly to make it as a whole with a certain displacement, so as to facilitate the adjustment according to the site size during installation and maintenance. During operation, the anti axial thrust can be transmitted to the whole pipeline. Advantages: simple and convenient installation, convenient valve installation; features: one side flange, one side welding.
