QJB Spherical compensator-Metal Expansion Joints

Overview

Spherical compensator also called spherical joint, mainly rely on angular displacement to absorb or compensate pipeline one or more directions laterial displacement, the compensator should be used in pairs, single spherical compensator has no compensation ability, can be used as universal joint.

It is mainly used for the pipe connection with higher flexibility,the ball is installed on the ball to rotate freely around the centre of gyration so as to compensate for the thermal expansion pipes,torsion ans vibration.It has d\advantages of high compensation,small occupation,lower fluid resistence,easy to install and low costa.It is mainly applicable for pipes with heating power of three-way displacement,large ground subsidence,strong shake and complex landform.

Features

Large amount of compensation
No closure force
Small force on fixed bracket
Using sealing technology to achieve long term reliable sealing
Easy to use and to install
All weather installation
Ideal for pumped sewerage pipelines
