Three, Tangshan Yanshan Steel Project supporting rubber joint introduction:

This contract mainly adopts flange rubber joint products, mainly including DN500 and DN700 caliber, model KXT, pressure PN10, mainly using natural rubber production, mainly used in normal temperature water.

It is composed of inner and outer layers of rubber, curtain layer and steel wire ring, and then combined with metal flange or parallel joint loose sleeve after vulcanization. This product can reduce vibration and noise, and can compensate thermal expansion and contraction caused by temperature change, widely used in various piping systems.

Installation instructions:

The rubber joint is strictly installed. Over displacement. Limited installation. When the rubber joint is installed on the ground, in the air and vertically, the actual working axial displacement pressure of the rubber joint is less than the supporting force of the pipeline, otherwise the anti-pull device should be installed to prevent the compression pull off when working. The pipe must have a fixed support or a fixed bracket, and the force of the bracket must be greater than the axial force. When vertical installation and overhead installation, the two ends of the product should be installed with the corresponding fixed support and stress support, in order to prevent pulling off after working pressure. The installation bolts should be tightened symmetrically step by step to prevent local leakage. Keep away from heat source during installation. Use media that does not meet the requirements of this product.
