Fig 1. Technical advice on pipe performance is<br />
available from our technical department.<br />
Fig 2. The rubber seal is designed to be located in a<br />
pre-formed groove at the spigot end of the pipe, in<br />
order to provide a watertight joint.<br />
Fig 3. Pipes can be designed to suit individual<br />
customer requirements. These 2,100mm diameter<br />
pipes used at the MEPAS contract in Liverpool were<br />
produced with 50mm cover to reinforcement.<br />
Fig 4. Superb quality is achieved. The pipes are<br />
vertically cast to ensure a completely homogeneous<br />
structure for the wall <strong>and</strong> are reinforced with an all<br />
welded spiral double cage.<br />
