The using advantages and composition of sleeve compensator
Sleeve compensator is also known as tube expansion joints, pipe expansion, is hot fluid pipeline compensation device, mainly used for the straight pipe linings.Suitable for hot water, steam, oil medium, through the sliding movement of the sliding sleeve external sleeve, compensation of thermal expansion.
Sleeve compensator is composed of outer cylinder and inner cylinder, outer cylinder and inner cylinder flange piece of finite rods, outer cylinder is equipped with limit block on the wall, between the outer cylinder and inner cylinder by the v-shaped sealing rubber ring.Thoroughly solved the existing expansion pipe packing friction, easy to leak, the shortcomings of difficult processing, easy to drag, with reliable sealing, low friction, small volume, light weight, pull, etc.
The reasons in the industry widely is mainly the following advantages:
1, the service life of the sleeve compensator is big, fatigue life and pipeline.Sliding surface through special processing, in salt water and salt solution environment corrosion resistant performance is good, more than 50 times higher than austenitic stainless steel.Weakened at the same time, after years of sealing effect caused by the wear, but again the fastening flange, enhance the sealing performance, bolt can be loosed, press circle, and then into a layer or two layers of sealing ring, compaction pressure, continue to use.
2, no request sleeve compensator of the chloride ion content, especially suitable for medium or chloride ion overweight on the system of the surrounding environment.
3, sleeve compensator is unidirectional and bidirectional compensation structure, two-way type is characterized by whatever medium from compensator He Duan inflows, the sliding sleeve are always free at the ends of the compensator, achieve two-way compensation function, increase the amount of compensation.
4, buried type sleeve compensator can directly buried underground, when installation is not set maintenance well, low engineering cost.rubber jointexpansion rubber joint
