Product Details

Limited Flexible Rubber Joint

Single Rubber Joint

Rubber Joint,

The product is mainly used for conveying liquid, gas, solid materials such as metal pipe flexible connection can compensate for displacement, vibration isolation noise, is a novel rubber damping products. It combines the mechanical extensibility of the metal expander and the multi-displacement function of the flexible rubber joint. It is not only mechanically expandable for installation and dismantling but also compensates for changes in the temperature of the pipe during operation Linear expansion and contraction as well as compensate for the ground settlement caused by the pipeline center of gravity and other causes of angular deviation, but also to eliminate vibration and noise transmission, is a versatile pipe compensator.

Features

● Minimal axial dimensions

● Limited weight

● Low warping forces

● High-resistance to work

● High-capacity acoustic damping
