seals are generally used for sealing at the bellows and bellows joints. However, many bellows are buried underground, and infiltration will occur at the joint for a long time. How to install the bellows rubber seal correctly Methods Generally, rubber seals are used for sealing at the bellows and bellows joints. However, many bellows are buried underground, and infiltration will occur at the joints over time. The main reason is the lap joint. There is a problem with the installation of the rubber seal at the place. Today we will mainly explain the specific method of correctly installing the bellows rubber seal. 1. Before the socket is inserted, first check whether the specifications of the rubber seal and the supporting products are intact, undamaged and elastic. The rubber seal should fit in the groove between the first and second peaks of the socket. The sealing ring must be properly packaged, and the number of installed sealing rings should be determined according to the relevant design requirements. If two seals need to be installed, a corrugation can be placed at intervals. 2. When joining, 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: DN400 and below pipes, the first person hangs the socket of the HDPE double-wall corrugated pipe with cotton yarn, the other person inserts the base with a crowbar obliquely, and resists the center of the double-wall end horizontal baffle. 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 in place by a 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 correctly seated and does not deform or fall off. The above is the specific method of correctly installing the bellows rubber seal. I hope it will be helpful to you when installing the bellows rubber seals seal. Ruichen Sealing
