Introduction and Functions of Sleeve Compensators

Introduction and Functions of Sleeve Compensators

A sleeve compensator, also known as a tubular expansion joint, consists primarily of a sleeve, a shell, and sealing materials. It is a type of compensator that is directly installed in any pipeline conveying non-corrosive fluids flowing in one or multiple directions. It is mainly used to absorb and compensate for axial thermal expansion displacements occurring downstream of linear pipeline auxiliary equipment.

Sleeve Compensator Instructions

Sleeve Compensator Instructions

Sleeve Compensator Instructions Sleeve compensator instructions: The sleeve compensator, also known as a pipe expansion joint or pipeline expansion joint, is a compensation device used in hot-fluid pipelines. It primarily serves as an auxiliary component for linear pipelines. It is suitable for media such as hot water, steam, and oils. The sliding sleeve compensates for thermal expansion by allowing the outer sleeve to slide relative to the inner sleeve.

How is the air tightness of a bellows compensator tested? What factors affect the service life of a bellows compensator?

How is the air tightness of a bellows compensator tested? What factors affect the service life of a bellows compensator?

How is the air tightness of bellows compensators tested? What factors affect the service life of bellows compensators? A bellows compensator with good air tightness will not leak the circulating medium and can absorb deviations in the pipeline. Therefore, high air tightness is a prerequisite for bellows compensators. So, how do manufacturers of bellows compensators test the air tightness of their products?
