Weights and Dimensions

CPM offer an extensive range of precast concrete flexible jointed pipes from DN 225 to DN 1800 including bends, junctions and fittings.

The Water Services Association publications, the Civil Engineering Specification for the Water Industry and Sewers for Adoption allow for a variety of production methods. CPM manufacture by high frequency vibration which produces a dense concrete of high strength and durability.

Flexible jointed pipes are manufactured and tested in accordance with BS EN1916:2002/BS 5911-1:2002 and kitemarked accordingly.

4. CPM specialised Flexilift system for handling/jointing purposes for pipes DN1200 to DN1800 is available.
5. Lorries with crane offload facilities are available for pipes up to DN 600 upon request, although site assistance would be required on certain diameters.
6. When ordering pipes which may have to joint with pipes already on site or previously laid, particularly extensions to contracts, it is important to advise the sales office accordingly in order to eradicate any jointing problems.
7. Flexible jointed concrete pipes can be supplied with perforations.
