Please note that all dimensions are approximate. Joint rings and integral seals are normally SBR comply with BS EN 681-1:1996. Other compounds such as Nitrile or EPDM can be supplied but may not be available from stock. *Pipes supplied with an in wall joint - no bell socket, (full flexibility at joint maintained).

The Milton Precast Flexilift system for handling/jointing purposes for pipes 1200mm up to 1800mm is available, as are lorries, with crane offload facilities for pipes up to 600mm, although site assistance would be required on certain diameters. Please speak to our sales team about this when ordering your pipes on 01795 425191 or sales@miltonprecast.com

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.

Milton Precast lubricant is advised for use on integral seal type pipes and we cannot guarantee that jointing of pipes with the use of other lubricants will be successful.

Junctions

Milton Precast junction from 100mm upwards can be fitted to all Milton pipe sizes. Branches can be made from drainage materials other than concrete and are normally fitted to both full length and short length pipes to suit customer requirements with Uni junctions are supplied fitted to pipes from 300mm up to 1800mm and to suit 150mm diameter connections.

The junction is produced by inserting a rubber gasket to BS EN 681-1:1996 into the main pipe at the factory, providing a watertight seal for the branch connection and making it less susceptible to site and transport damage.

The Milton Precast uni-junction is designed to suit 150mm slimline clay pipes. To connect to plastic pipes, an adaptor coupling from the clay to the plastic pipe will be required. Alternatively for certain plastic pipes an adaptor bush is available. Contact our Sales Office for full compatibility details.

Bends

When ordering bends where specific angles, centre line lengths or radii are required, these must be specified at the time of order, (specials made to order).

Bends may not necessarily have the same load-bearing capacity as the pipes with which they are to be laid. It is therefore recommended that they should be surrounded by suitably designed in-situ concrete where significant load conditions have to be met, or where anchorage of the pipeline is required.
