Ovoid concrete pipes are produced and tested in accordance with the relevant provisions of BS EN1916:2002/BS5911-1:2002 Class 150 including dimensional tolerances, crushing, hydrostatic, water absorption and joint tests.
The ovoid pipe has better velocity characteristics at low flows than equivalent circular pipes, which provides:
Lower operating costs, where some sewers may be laid without the need for pumping. Better self cleansing and therefore less risk of siltation and blockage.
Reduced costs of trench excavation resulting from shallower gradients.
The 600×900 & 800×1200 ovoid pipes are supplied with two lift anchors cast in the top for use with ‘Flexilift’ lifting/jointing system.
‘C’ hook available for lifting/jointing 400×600 ovoids.
Lifting/jointing equipment can be supplied on request.
Short lengths of either spigot/socket butt pipes can be supplied for building into the manhole wall for the 600×900 and 800×1200 ovoids and are 1250mm long and 625mm long for the 400×600 pipe.
Junctions can be fitted and can be made from drainage material other than concrete.
