Correct Installation Method Of Bellows Rubber Sealing Ring

The rubber sealing ring should be made of high-quality natural rubber and EPDM. They should have good elasticity and stretch properties. In addition, the design of the rubber ring should fully consider the consistency with the pipe waveform, the height and thickness of the rubber ring, and the tightness with the pipe seat. A qualified pipeline must have a rubber sealing ring with a reasonable structure. Rather than any structural rubber seal.

The bellows rubber sealing ring is a socket joint connected by an elastic sealing rubber ring. The rubber ring joint shall meet the following requirements of the seal manufacturer:

1. Before socketing, first check whether the specifications of the rubber sealing ring and the matching products are intact, non-destructive and elastic. The rubber seal should fit in the groove between the first and second peaks of the receptacle. Sealing rings must be properly packaged, and the number of sealing rings to be installed should be determined according to relevant design requirements. If you need to install two sealing rings, you can place a bellows at intervals.

2. When connecting, clean the inner wall of the double-wall bellows socket, lubricate the inner wall of the socket and the rubber ring of the PE bellows socket, and then align the central axis of the end face of the socket.

3. The interface method should be carried out according to the following procedures: for pipes of DN400 and below, the first person hangs the socket of the HDPE double-wall corrugated pipe with a cotton yarn rope, and the other person inserts the base obliquely with a crowbar, and resists the center of the double-wall end horizontal baffles. The corrugated pipe, and then slowly insert the polyethylene corrugated pipe into the pipe seat of the HDPE double-wall corrugated pipe to the predetermined position; the E pipe can be pulled into place by two-hand lever hoist. When the joint is closed, the handcuffs on both sides of the pipe joint should be pulled synchronously so that the rubber sealing ring is in place correctly without deformation or falling off.
