AF flange type loose sleeve expansion joint description:
After the loose sleeve expansion joint is installed on the pipeline, tighten the nut elastic sealing ring, and the nut is inclined to each other under the action of the nut gland, and it is pressed tightly on the outer ring of the pipe to seal and connect effect. When the temperature changes, the pipe can expand and contract freely in the middle of the joint, the foundation sinks, the pipe can be deflected, and the sealing is ensured without leakage, so as to achieve the purpose of automatic Compensation.
