Vitrified clay pipe (VCP) is a pipe constructed from a mixture of clay and shale that has been vitrified at a high temperature to produce a hard, inert ceramic. BS 65 discusses specifications for vitrified clay pipes, fittings, and ducts, also flexible mechanical joints for use solely with surface water pipes and fittings.
BS 65 specifies requirements for vitrified clay pipes and fittings with or without sockets, and compatible accessories, for the construction of drainage and sewerage systems, operated as gravity pipelines, or for use as ducts.
BS 65 applies to both glazed and unglazed products.
Note: The pipes and fittings specified may be suitable for use with joints other than flexible mechanical joints, but such joints are outside the scope of BS 65.
BS 65 on flexible mechanical joints with surface water VCP fittings and ducts specifications is useful for:
VCP is commonly used in gravity sewer collection mains because of its long life and resistance to almost all domestic and industrial sewage.
Normal and extra chemically resistant pipes and fittings are covered by BS 65, when supplied without flexible mechanical joints, for example, to meet repair situations or for use with special jointing compounds. Surface water pipes and fittings are also covered by the standard, together with ducts.
BS 65 also specifies performance requirements for flexible mechanical joints used with surface water clay pipes and fittings.
The requirements specified cover certain dimensions and tolerances, physical and performance characteristics, marking and sampling, and testing and inspection procedures to verify compliance and facilitate quality control.
BS 65 guides you with manufacturing high-quality sewage system components, which extends the life of a sewage system and reduces the need for costly dig-ups.
