Function Of Internal Sleeve

The internal sleeve is an important component of bellows expansion joints. A device which minimizes contact between the inner surface of the bellows of an expansion joint and the fluid flowing through it . Internal sleeves shall be specified in all applications involving flow velocities which could induce resonant vibration in the bellows or cause erosion of the convolutions resulting in substantially reduced bellows life.

EhaseFlex advice you add internal sleeve for axial expansion joints.Expansion joint is widely used in various occasions that need to compensate for pipeline deformation, such as petroleum, chemical, electric power, metallurgy, paper making, food and other industries. Especially in the high temperature, high pressure, corrosive environment, the expansion joint is playing an irreplaceable role.
