Hengzhong Flanged loose sleeve expansion joint

Composition of AF(VSSJA) flanged loose-sleeve expansion joint:

The flange-loose sleeve expansion joint is composed of a body, a gland, a sealing ring and a fastener, including a body, a gland, two sealing rings and a number of stud nuts each. Socket is also suitable for connection with steel pipe, cast iron pipe, ductile iron pipe, PAC pipe, ABS pipe, etc.

Flange loose sleeve expansion joint product introduction:

Flange loose sleeve expansion joint is also called flange loose sleeve compensation joint, flange loose sleeve expansion joint. Flange loose sleeve telescopic joint is composed of body, gland, sealing ring and fasteners. It adopts the same sealing principle as gland loose sleeve telescopic joint. One end of the joint is flange connection and the other end is socket connection. At the same time, the connection can compensate the axial displacement of the pipeline and a certain amount of deflection and eccentricity, so as to protect the valve and other equipment. Socket is also suitable for connection with steel pipe, cast iron pipe, ductile iron pipe, PAC pipe, ABS pipe, etc.

Installation instructions of flanged loose-sleeve expansion joint:

After the expansion joint of the flange loose sleeve is installed on the pipe, tighten the elastic sealing ring of the nut. Under the action of the nut gland, it relies on the mutual inclination to tighten the sealing and connecting function of the outer ring of the pipe. When the temperature changes, the pipe can freely expand and contract in the middle of the joint, when the foundation sinks, the pipe can be deflected, and ensure that there is no leakage seal, so as to play the purpose of automatic compensation.
