Let's learn about expansion joints!
Expansion joints are pipe compensation joints, a new product connecting pumps, valves, pipes and other equipment to pipelines. They are connected as a whole using bolts, allowing for a certain amount of displacement. Types include AY type pressure cover expansion joint, AF type flange loose expansion joint, BF type single flange limit expansion joint, B2F type double flange limit expansion joint, BY type pressure cover loose limit expansion joint, CF single flange transmission joint, and C2F double flange transmission joint.
Installation Instructions for French Expansion Joints
After the loose expansion joint is installed on the pipe, the nut and elastic sealing ring are tightened. Under the action of the nut cover, they are inclined to each other and tightly pressed against the outer circle of the pipe to achieve sealing and connection. When the temperature changes, the pipe can freely expand and contract in the middle of the joint. When the foundation subsides, the pipe can deflect and ensure that the seal is leak-proof, thus achieving automatic compensation.
