Overview

Covering Limited Telescopic Dismantling Joint is improved by adding the limited device on the basis of loose flexible rubber joint. Fit it with double nut at the maximum compensation volume, the product functions as limiting the position of rubber joint. It secures the safe operation of the pipe efficiently; especially applies to the pipeline which vibrates fiercely, be with somewhat deflection, or is on the corner.

It is suitable for welded pipe connecting points ,please adjust the length of both ends when installating for fixed welding, which will allow the pipe extended lock retractable, ensuring safe operation of the pipeline.

Covering Limited Telescopic Dismantling Jointis applicable for welding the pipeline on the both sides. During the installation, loose the gland, adjusts the length, and then welds the short pipes on the both sides to the pipe. At last, fix nut with diagonal method and adjusts it.
