Underground Clay Drainage System – Densleeve

Description

Densleeve underground clay drainage system of plain-end vitrified clay pipes and fittings with flexible sleeve couplings, was developed for building drainage and associated sewerage and is manufactured to comply with the stringent requirements of BS EN295.  Sizes are DN100-DN300.

Clayware

Vitrified clay plain-end pipes and fittings, manufactured in accordance with the requirements of BS EN295-1. The standard lengths of pipes are convenient for handling and laying and allow for flexible joints at sufficiently frequent intervals to enable the pipeline to withstand settlement or other ground movement after installation.

Sleeve Couplings

Manufactured in high impact polypropylene with elastomeric seals providing watertight, flexible mechanical joint assemblies, complying with BS EN295-1: System G.

Standard Coupling Seals

These are manufactured from elastomers conforming to the performance requirements of BS EN681-1. EPDM seals supplied as standard; Nitrile seals are also available for use in contaminated ground.

Joint Performance

Densleeve joint assemblies meet all the requirements of BS EN295-1. They accept angular deflection and shear resistance without leakage, when tested under an internal or external water pressure of 50kPa (5 metres head).

Aggressive Environments

The standard Densleeve pipes, polypropylene couplings and elastomeric sealing rings are resistant to attack from substances which are commonly encountered in sewers. Where more aggressive effluents or environments are present, other types of coupling seals may be required. Alternatively, Naylor has a separate division, Hathernware Thermachem, which manufactures chemical drainage – ceramic pipes for exceptional high temperature or chemically aggressive environments. Contact the Naylor Technical Sales Department for advice.
