BS 5911-1:2002 CLASS 150
CPM Group Ltd
CPM offers a range of concrete ovoid pipes including a flexible joint seal for use with both foul and surface water applications.
The ovoid concrete pipe is produced and tested in accordance with the relevant provisions of BS EN1916:2002/BS5911-1:2002 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.
