We have both office based and external technical personnel able to answer queries and provide specialist DrainageVitrified clay DrainageHandbook1 Tel: 01226 790591 Fax: 01226 791531 Naylor Densleeve underground Drainage system of plain-end vitrified clay pipes and fittings with flexible sleeve couplings, was developed for building Drainage and associated sewerage and is all manufactured to comply with the stringent requirements of BS is available in diameters DN100, 150, 225 and 300; in addition DN200 and 250 are manufactured for key export markets. When installed in general accordance with the Naylor Sitework Instructions the Naylor Densleeve system meets the latest technical requirements of the Building Regulations, BS8005 and BS8301.

3 DescriptionClaywareVitrified 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 CouplingsManufactured in high impact polypropylene with elastomeric seals providing watertight, flexible mechanical joint assemblies, complying with BS EN295-1: System G. Standard Coupling SealsThese are manufactured from elastomers conforming to the performance requirements of BS EN681-1.

4 EPDM seals supplied as standard; Nitrile seals are also available for use in contaminated PerformanceDensleeve 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 EnvironmentsThe 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.

6 As it is impracticable for any single manufacturer to offer pipes and fittings in the full range of strengths, Naylor has standardised on the strengths shown in the table PipesThe pipe lengths detailed below are standard at the time of publication but may vary due to changes in manufacturing clay pipes and fittings are rigid and do not distort under loading. Their high inherent strength ensures stability even at extreme depths of EconomyDensleeve pipes can often be laid on the natural, trimmed trench bottom or where not possible on a 50mm bed of inexpensive granular material such as recycled aggregates. As dug material can be used for the backfill, all resulting in significant savings in granular bedding and Temperature ResistanceThe Densleeve system has good corrosion resistance and can accommodate controlled discharges of up to 60-70.

7 For more extreme operational conditions, the Hathernware Thermachem range of chemical Drainage is available:FCR - Fully Chemically ResistantHT - High Temperature - For very high temperature discharges and thermal shock Densleeve system is extremely durable. For design purposes, a vitrified clay pipeline can be considered to have unlimited JettingThe Densleeve system, when installed in general accordance with the Naylor Sitework Instructions Booklet is guaranteed for the lifetime of the system against penetration of the pipe wall caused by high pressure water jetting when operated within the following maximum parameters. Pressure - 7500psi (510 bar) Flow rate - 20gals/min ( ) Time - Static for 5 minutesQuick InstallationPipe jointing is a straightforward manual push fit operation.

8 Testing and backfilling can start Lengths and DeliveryNaylor Pipes are supplied in easy-to-handle lengths. They are delivered in convenient packs with optional mechanical offloading equipment available on the delivery CuttingWhere shorter lengths of pipe are required, pipes may be easily cut on site. RangeA full system is offered from DN100 to DN300 with an extensive range of fittings, including bends, junctions, tapers and access items, particularly suitable for building Drainage can be used in conjunction with other Naylor underground and with other above-ground systems. Connections are made by using purpose-made connectors and adaptors or by the use of Band-Seal Trench BeddingsSee the Naylor Drainage Design Handbook for the depths of cover between which Naylor Densleeve pipes conforming to BS EN295-1 can be laid in any width of is a major advantage of the Densleeve system that plain-end pipes can be quickly and easily cut to intermediate lengths on site and can still be jointed using normal couplings.
