The sleeve type compensator is called a tube expansion joint, which is a compensation device for thermal fluid pipelines and is mainly used for the auxiliary equipment of straight pipelines . It is suitable for hot water, steam and grease media, and can compensate for thermal expansion through the sliding movement of the sliding sleeve against the outer sleeve.
Sleeve type compensator is suitable for medium engineering pressure and medium temperature ℃~℃.
The sleeve type compensator uses a new type of sealing material, flexible graphite ring, which has the characteristics of high strength, small friction coefficient (~), no aging, good effect, and easy maintenance.
The sleeve type compensator has a long service life and the fatigue life is equivalent to that of the pipeline. The sliding surface has been specially treated and has good corrosion resistance in environments such as salt water and salt solutions, which is more than times higher than that of austenitic stainless steel. At the same time, when the sealing effect is weakened due to wear after many years, the flange can be tightened again to enhance the sealing performance. You can also loosen the bolts, remove the pressure ring, install one or two layers of sealing rings, and tighten the pressure ring. ,continue to use.
Sleeve type compensator has no requirements on chloride ion content, and is especially suitable for systems where the medium or surrounding environment exceeds the chloride ion standard.
Sleeve-type compensators are divided into one-way and two-way compensation structures. The characteristic of the two-way type is that no matter which end the medium flows into the compensator, the sliding sleeves at both ends of the compensator always slide freely to achieve two-way compensation. Increase the amount of compensation.
Directly buried sleeve compensators can be buried directly underground. No maintenance wells are required during installation, and the project cost is low.
Use of sleeve compensator: Sleeve compensator is a compensator installed directly in the pipeline of single-phase or multi-phase fluid. It is mainly composed of sleeve (core tube) shell sealing material, etc. It is used to compensate for the axial expansion and contraction of the pipeline and the axial rotation at any angle. It has the characteristics of small size and large compensation amount. It is widely used in transportation pipelines in urban heating, metallurgy, mining, power generation, petrochemical construction and other industries.
The sleeve-type expansion joint uses a new type of sealing material, flexible graphite ring, which has high strength, long life, and a fatigue life equivalent to that of a pipe. The sleeve-type telescopic section is divided into one-way and two-way compensation structures. The characteristic of the two-way type is that no matter which end the medium flows into the compensator, the sliding sleeves at both ends of the compensator always slide freely, achieving a two-way compensation effect and increasing the compensation amount. .
