Before installing HDPE drainage pipes, it is necessary to check whether there are cracks in the appearance and whether there are quality problems in the pipes, and repair or replace them in time if any problems are found. Secondly, check whether the rubber ring matches the pipe and whether there is a quality problem. Then wipe the socket and flare connection with a clean towel to ensure its cleanliness. Insert the rubber ring into the socket of the bellows in the correct direction, i.e. at the second crest. During insertion of the rubber ring, there must be no twisting or reverse installation. Apply lubricant to the rubber ring and the socket. The lubricant can be replaced with soapy water. The lubricant should be used in an appropriate amount to prevent the lubricant from flowing into the socket bellows, so as to reduce the friction between the rubber ring and the flaring, thus causing the rubber ring Rollover situation.
