Loose Sleeve Compensation Joint
▪ Composed of a body, a sealing ring, and a compression member, it is a device for loosely sleeved connection pipes that absorbs axial displacement and cannot withstand pressure thrust.

Loose Sleeve Limit Compensation Joint
▪ It is composed of loose sleeve compensation joints and limit expansion pipes to prevent leakage or damage of compensation joints due to excessive displacement of the pipeline. It is used to absorb axial displacement and bear pressure thrust within the allowable displacement range.

Loose Sleeve Force Transmission Compensation Joint
▪ Composed of flange loose sleeve compensation joints, short pipe flanges, force transmission screws and other components. It transmits the pressure thrust of the connected parts and compensates for pipeline installation errors. It does not absorb axial displacement and is a device used for loose sleeve connection with pumps, valves and other accessories.

Large Deflection Loose Sleeve Compensation Joint
▪ Composed of short pipe flange, body, gland, retaining ring, limit block, sealing pair and compression component. It's a device used to absorb axial displacement and angular displacement with a deflection of 6°~7°.

Spherical Compensation Joint
▪ Composed of a spherical shell, a sphere, a sealing pair, and a compression component. It is a pipe connecting device used to absorb the flexible displacement of the pipe.

Pressure Balanced Type Compensation Joint
▪ Composed of a body, a sealing ring, a pressure balance device, a telescopic tube and a compression member, it is a device for loose sleeve connection pipes that can balance the internal pressure and thrust while absorbing axial displacement.
