AF Flanged Expansion Joint丨Flange Adapter

Flange loose sleeve expansion joint is also called flange loose sleeve compensation joint, flange loose sleeve expansion joint, flange adapter. Flange loose sleeve expansion joint is composed of body, gland, sealing ring and fastener. It adopts the same sealing principle as gland loose sleeve expansion joint. The connection method is flange connection at one end and socket connection at the other end. It is suitable for Connection of equipment such as valves and pipelines. At the same time, it 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. The socket and socket are also suitable for connection with steel pipes, cast iron pipes, ductile iron pipes, PAC pipes, ABS pipes, etc.

Flanged loose sleeve expansion joint installation instructions

After the flange loose sleeve expansion joint is installed on the pipe, tighten the elastic sealing ring of the nut, and rely on the mutual slope under the action of the nut gland to tightly press the outer ring of the pipe to seal and connect. When the temperature changes, the pipe can expand and contract freely in the middle of the joint, when the foundation sinks, the pipe can be deflected, and the seal can be ensured without leakage, so as to achieve the purpose of automatic compensation.

Due to the large temperature change of connecting the expansion pipe or bellows, the use of expansion joints is a protective measure. Expansion joints are new products for connecting pumps, valves, pipelines and other equipment to pipelines. They are connected by full bolts. Make it a whole and have a certain amount of displacement, which is convenient for installation. Can withstand the axial pressure of the pipeline. In this way, during installation and maintenance, it can be adjusted according to the on-site installation size. During work, it not only improves the work efficiency, but also plays a certain role in protecting the pipeline equipment such as pumps and valves.
