The performance of the rubber joint vulnerable to what limitations.
Rubber joint (also called a song of flexible rubber joint, rubber bellows) used for transporting materials in solid, liquid, gas and other various flexible connection of pipeline, can reduce vibration and noise attenuation, and can eliminate heat bilges cold shrink and land and foundation settlement on the phenomenon of damage to equipment and piping, rise to adjust axial, angular, lateral displacement and compensation.Due to its easy installation, superior performance, has been more and more piping designers know, rubber joint has been more and more widely used.Rubber joint type can be divided into normal pressure and pressure type two kinds.Atmospheric model is usually made of single rubber canvas, no shape requirements, manufacturing process is simple;Pressured type is the rubber joint, must use multilayer frame material, shape is strict, so the manufacturing process is more complicated.At present most of the rubber joint manufacturers adopt split compression molding manufacturing mold core, its semi-finished plastic tube for joint by hand and become.This manual process links, the quality is not easy to control.When sulfide, because of the cavity volume must be less filling adhesive, easy to lack of glue, fill glue, flow, forced the easily washed away the skeleton fibers.In addition, mould manufacturing complex, the mold core, mold unloading process making, skeleton fibre elongation factors such as constraints, the size of the waveform, quantity, amount of compensation is limited.
