Sleeve compensation joint is also called sleeve compensator, sleeve expansion joint. This product belongs to a kind of compensation component, mainly composed of sleeve (core tube), shell, sealing material, etc., used to compensate the axial expansion and contraction of the pipeline and the axial rotation at any angle, and has the characteristics of small size and large compensation Hot water, steam, grease and other media can compensate for thermal expansion according to the sliding movement of the outer sleeve of the drag sleeve.
Sleeve-type compensators are widely used in pipelines for urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries. It is mainly composed of sleeve (core tube), shell, sealing material, etc. The new type of sealing material flexible graphite ring is selected, which has the characteristics of high strength, low friction coefficient (0.04~0.10), no aging, good effect, and convenient maintenance; applicable medium engineering pressure ≤ 2.5MPa, medium temperature- 40℃~600℃; Anti-pull-breaking equipment is designed to ensure that it will not be opened when it is stretched to a certain extent, thereby greatly improving the stability of all pipe network operations.
Sleeve compensator is used at the end of the pipeline (that is, the end of the pipeline is used), the end buttress should be considered to offset the torsion caused by the medium in the pipeline. The steel sleeve compensator is mainly used in the mechanical displacement and heating displacement of the pipeline system to absorb vibration and reduce noise. It can carry out displacement absorption in every direction.
Users need to clarify the following conditions when selecting sleeve compensators:
1. Use medium conditions (please specify when selecting dusty, corrosive and corrosive medium, so as to facilitate the selection of materials when making).
2. Working temperature.
3. Compensation amount (should be greater than the actual compensation amount when determining the compensation amount).
4. Pipe diameter and connection method (flange connection type, takeover connection type) provide socket connection size when pipe connection is selected. Provide dimensions if special or non-standard flanges are used. When the installation length is restricted, please indicate the delivery length.
5. The pressure of the compensator.
