1 The Naylor ensleeve 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 EN95. ensleeve is available in diameters,, and ; in addition and are manufactured for key export markets. When installed in general accordance with the Naylor Sitework Instructions the Naylor ensleeve system meets the latest technical requirements of the Building egulations, BS8005 and BS830. escription Clayware Vitrified clay plain-end pipes and fittings, manufactured in accordance with the requirements of BS EN95-. 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 EN95-: System G. Standard Coupling Seals These are manufactured from elastomers conforming to the performance requirements of BS EN68-. EPM seals supplied as standard; Nitrile seals are also available for use in contaminated ground. Joint Performance ensleeve joint assemblies meet all the requirements of BS EN95-. They accept angular deflection and shear resistance without leakage, when tested under an internal or external water pressure of 50kPa (5 metres head). ggressive Environments The standard ensleeve 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. lternatively, Naylor has a separate division, athernware, which manufactures chemical drainage - ceramic pipes for exceptional high temperature or chemically aggressive environments.

Pipes and Fittings Vitrified clay plain-end pipes & fittings with flexible polypropylene coupling joints, all to BS EN95- : System G. (ensleeve type as manufactured by Naylor rainage td, Clough Green, Cawthorne, Barnsley, S75 4, England). vailability ensleeve is available either directly from the manufacturer, from Naylor stocking depots or from hundreds of Merchant Stockists throughout Britain as well as Naylor gents overseas.

2 Structural Performance ensleeve pipes can usually be laid directly on a hand trimmed natural trench bottom with selected, excavated materials (Class Bedding) used as backfill. Crushing Strengths BS EN95- includes a variety of crushing strengths for each nominal size of pipe as it takes into account the strength requirements in various parts of Europe. s 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 below. ensleeve Packs The pipe lengths detailed below are standard at the time of publication but may vary due to changes in manufacturing facilities. Pipe Nominal Size () ange Crushing Strength kn/m (System G) Class 80 Standard ength (metres) full system is offered from to with an extensive range of fittings, including bends, junctions, tapers and access items, particularly suitable for building drainage applications. ensleeve 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 couplings. Strength Vitrified clay pipes and fittings are rigid and do not distort under loading. Their high inherent strength ensures stability even at extreme depths of cover. Bedding Economy ensleeve 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. s dug material can be used for the backfill, all resulting in significant savings in granular bedding materials. Chemical and Temperature esistance The ensleeve system has good corrosion resistance and can accommodate controlled discharges of up to For more extreme operational conditions, the athernware range of chemical drainage is available: FC - Fully Chemically esistant T - igh Temperature - For very high temperature discharges and thermal shock cycling. urability The ensleeve system is extremely durable. For design purposes, a vitrified clay pipeline can be considered to have unlimited life. Water Jetting The ensleeve 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 - 7psi (50 bar) Flow rate - 0gals/min (.5ltrs/sec) Time - Static for 5 minutes Pipe Trench Beddings See the Naylor rainage esign andbook for the depths of cover between which Naylor ensleeve pipes conforming to BS EN95- can be laid in any width of trench. dvantages It is a major advantage of the ensleeve system that plainend pipes can be quickly and easily cut to intermediate lengths on site and can still be jointed using normal couplings. This feature retains the ease in jointing, reduces wastage and damage and is particularly cost effective. Flexibility The flexible joints ensure that the pipeline will accommodate minor settlement and ground movement without failure. Quick Installation Pipe jointing is a straightforward manual push fit operation. Testing and backfilling can start immediately. Pipe engths and elivery Naylor Pipes are supplied in easy-to-handle lengths. They are delivered in convenient packs with optional mechanical offloading equipment available on the delivery vehicle. Easy Cutting Where shorter lengths of pipe are required, pipes may be easily cut on site. Tel: Fax:
