Elastic sleeve compensator
1、 Introduction
Sleeve compensator is the oldest pipeline compensator. Due to its large compensation amount, low resistance, low cost, and long cylinder life, it was widely used before the 1970s. However, its sealing part is prone to leakage and requires maintenance. Sleeve type compensator, also known as tube type expansion joint, is a compensation device for thermal fluid pipelines, mainly used for straight pipes**The axial thermal expansion displacement absorption compensation that occurs after the installation of auxiliary equipment is a compensator directly installed in any pipeline that transports non corrosive unidirectional or multi-directional fluids. Sleeve type compensator Widely used in transportation pipelines for urban heating, metallurgy, mining, power generation, petrochemicals, construction and other industries.
2、 Structure
There are mainly sleeves(Core tube), shell, sealing material, etc Used to compensate for axial expansion and axial rotation of pipelines at any angle It is suitable for hot water, steam, and grease media due to its small size and large compensation amount. The compensation for thermal expansion is achieved by the sliding motion of the outer sleeve through the sliding sleeve.
