Coupling joint are pressure rated to the appropriate pipe standards. Working pressure is generally two-thirds of maximum test pressure shown in the schedules of dimensions. These pressures apply to a buried line with adequate thrust blocks or to pipelines above ground anchored at ends and at all changes of direction also secured against side thrusts at each joint. Couplingjointthough capable of accommodating reasonable expansion and contraction, do not mechanically prevent separation of pipe ends subject to end thrust, and this must be prevented by other means. To prevent separation of pipe ends, harness assemblies consisting of lugs for welding to adjacent pipes, and connecting tie rods can be supplied.Pipes must be anchored against end load, particularly when the pipeline is laid above ground. A buried pipeline normally needs anchoring only at abrupt changes in direction and at junctionsor stop ends. Gaskets are of a EPDM rubber and are suitable for water and sewerage services, chemicals and dilute acids in the emperature range –50°C to +90°C. Other sealing materialscan be used, increasing temperature range to greater than 90°C. These materials are available on request.


Couplings are designed for use on air, water, sewer and gas pipelines. The couplings are wide tolerance product and fit all popular standard pipe sizes,

thus dramatically reducing the number of product to be stocked for maintenance purposes. The couplings are suitable for steel, PVC, ductile iron, asbestos

cement, GRP, cast iron and concrete pipes.
