What are the requirements for installing rubber expansion joints at height?

Rubber expansion joint is a kind of flexible connector on hardware pipeline. Rubber flexible joint can be used as a live flange connector of hardware pipeline. Rubber flexible joint has the characteristics of small size, light weight, good ductility and easy installation and maintenance. The installation can cause horizontal, diameter and angular offset, and is not restricted by pipe blockage, flange cloth parallel surface, etc.
 
Rubber soft connection in the application of the whole process of installation, according to the project site installation and application of the situation, select the custom-made suitable specifications, to prevent the installation and application of the site, the commodity socket does not match, the installation is not timely. When installing rubber soft connections at high places, the specific work of rubber soft connections radial offset working pressure is lower than the bearing capacity of the pipeline, otherwise, anti-pull off equipment should be installed to avoid the work of the force pull off. The pipeline has a fixed immovable support point or fixed bracket, the force of the fixed bracket exceeds the axial force. In vertical installation and empty frame installation, both sides of the rubber soft joint commodity should be installed with the appropriate support frame and bearing force.
 
When the spherical rubber soft joint is installed, the extruder screw of the ground bolt should be extended into both sides of the joint head, and the ground bolt of each flange internal thread should be tightened constantly and evenly according to the pinch punching method to prevent pressure deviation. When the spherical rubber soft joint is applied to the centrifugal pump import and export trade, it should be located near the side of the centrifugal pump, and the metal material reducer joint should be installed in the middle of the centrifugal pump, and installed at the large diameter of the size head. When the pipeline causes working pressure and exceeds the pressure, the spherical rubber soft joint should be taken one gear above the pressure. High-rise buildings to drainage or inclined 45 degrees to drainage, the pipeline should be fixed immobile on the bracket, fixed body bracket or burden.
 
When installing the rubber soft joint, the extruder screw of the foot bolt should be extended to both sides of the connection head, and the foot bolt of each flange inner hole should be tightened constantly and evenly according to the top angle filling pressure to avoid pressure deviation. The fillet connection head should be tightened proportionally by applying the standard wrench, and the side shift rod should not be used to make the tee joint slide buckle, slide prong and rupture, and should be maintained regularly to prevent loosening from causing dislodgement or leakage.
