Sleeve compensator is introduced
Sleeve compensator is also called the expansion joint, or the slip joint. By work constitute the main body of the corrugated pipe (a kind of elastic element) and the end of tubes, stents, flange, pipe and other accessories.
Belongs to a kind of compensation components. Use its work subject bellows telescopic deformation effectively, to absorb piping, pipe, container, etc is produced by the reason of heat bilges cold shrink and the size of the change, or compensation pipeline, pipe, container, etc. The axial, lateral and angular displacement. Can also be used for noise reduction vibration reduction. Widely used in modern industry.
Compensator is also known as expansion, expansion joint, corrugated compensator. Compensator is divided into: corrugated compensator, sleeve compensator, rotating compensator, square several types, such as natural compensator with corrugated ?
1. The compensation Angle to the absorption pipeline axial, lateral, thermal deformation.
2. Corrugated compensator expansion amount, valve pipe installation and removal.
3. The vibration absorption equipment, reduce the influence of equipment vibration on pipeline.
4. Absorb the earthquake, subsidence deformation of pipeline.

Sleeve compensator for detailed information
Product name: sleeve compensator
Nominal diameter: DN80 ~ DN1000 (mm)
Design pressure: 1.0 ~ 4.0 (Mpa)
Design temperature: - 40 ℃ ~ 250 ℃
Connection mode: flange/welding
Sealing material: preparation of packing products, ptfe, rubber products, oil seal, etc

The performance characteristics of sleeve compensator
Packing sealed sleeve compensator, is a kind of contact seal, outer casing and core tube, fill in the elastic sealing material between the axial force of the packing pressure can clingy in core pipe surface, after USES the elastic deformation of the seal material compensation sealing surface wear, prevent leakage of medium, at present has developed from a single packing into combination, such as hard packing in the deep, soft packing gland near; Hard or soft packing the middle in the seal oil, leak, adopt the method of filling oil leakage.
Mechanical sealed sleeve compensator, is made up of at least a pair of end face perpendicular to the axis of rotation, in under the action of fluid pressure and the elastic compensation agencies, keep post merger with another end relative sliding, and constitutes a ? to prevent fluid leaks

The type of sleeve compensator
Directly buried sleeve type compensator, adopt advanced sealing structure and sealing material, suitable for hot water, steam, oil medium, through the sliding movement of the sliding sleeve external sleeve, compensation of thermal expansion. The features of reasonable structure, safe and reliable, long service life, no leakage, easy installation and maintenance, wide applicable scope, etc. At the same time, is advantageous for the pipeline design, easy installation, can reduce the fixed bracket set.
Bidirectional sleeve compensator, in the normal outer casing two directions are telescopic core tube, has twice compensation type of grain, and for two-way compensation, to reduce the length of the using two normal size and cost.
, double seal corrugated sleeve compensator (patent products), has a double insurance role. This product will be corrugated tube compensator, as on the outside of the bellows compensator adds a mechanical seal, bellows, once appear problem, compensator can still work normally. Reliable performance, improve the flexural capacity. Due to increase the mechanical seal in the bellows inside the bellows isolation with the outside world, from outside harmful substances, especially chlorine ion is more reliable, the work of bellows compensator mechanical seal at the same time increased the activity of the guiding role, improve the flexural capacity.
, disposable sleeve compensator for buried pipeline preheat welding in pipe surfaces in place after death, outer casing and core tube can no longer do relative movement, and then the landfill, has the characteristics of life with pipe.

The application range of the sleeve compensator
Can be widely used in chemical, oil, thermal power, metallurgy, urban centralized heating pipe network, such as cooking and high erection of the pipe.

Sleeve compensator is the use of the environment
Environmental media, using surface thermal spraying of high corrosion conditions.
Environmental media, the degree of corrosion medium, the conditions of using temperature higher than 120 ℃, using chromium plating surface.
Environmental media, corrosion degree is low, the temperature is below 120 ℃ condition using galvanized surface.
