In order to effectively resist the pull-out force against to the connection position of the PE drainage pipe and the manhole structure caused by the settlement of the foundation, Smart Joint overall embedded design of manhole adapter effectively ensures the HDPE pipe system is safety withstand the forces.
The rigid manhole connectors , it can be both sides with long spigot which look like a PE puddle flange. It is machined from a single piece of hollow PE100 bar, with an embedded seal ring on the puddle edge.
The electrofusion type includes an electrofusion sleeve and an adaptor. The adaptor spigot end that fuses to the pipe and an electrofusion sleeve that is plastered into the manhole chamber wall.
