Description

Standard Couplings

Flexseal provides the most extensive range of Standard Couplings available in the marketplace and has revolutionised traditional pipe repair methods over the years. Flexseal Standard Couplings are specifically designed to connect and repair pipes of different materials or sizes used in sewerage, drainage and other underground applications. When excavation work is required to repair a damaged pipe, Flexseal Standard Couplings will reduce the amount of time required and minor differences in pipe diameter can be accommodated. The combination of a durable design and excellent sealing properties when tightened to the correct torque enable the Flexseal Standard Coupling to provide a reliable seal on rough pipe surfaces e.g. concrete, as well as on smooth surfaces e.g. PVC. Standard Couplings can be combined with Flexseal Bushes in order to act as an adaptor between pipelines of differingoutside diameters. Flexseal can also supply the product with nitrile sleeves for use with effluent which may be contaminated with hydrocarbons. Couplings are also available with Grade 1.4401 (316) stainless steel for improved corrosion protection.

Applications

When used individually or combined with bushes, Flexseal StandardCouplings have many applications in the construction, repair andmaintenance of pipe systems:

• As a joint for plain ended pipes
• Repair and maintenance of existing pipelines
• Connecting short and cut lengths of pipe
• Making post construction connections to an existing pipeline
• Reconnection of laterals on renovated sewers
• Introducing a rocker pipe outside manholes or structures
• When used with bushes can accommodate differing pipe diameters

Benefits

• Withstands an internal pressure of up to 2.5 bar
• A proven, tested and durable coupling design ensuring a high performance and a reliable connection
• Stainless steel shear band provides excellent resistance to heavy loads and shear forces
• Reduces excavation work
• Complies with WIS 4-41-01 (all public sewers and sewers for adoption)
• Complies with EN681-1: 1995 and BS EN 295 Part 4 requirements for vitrified clay pipes and fittings
• Shear band ensures joint integrity and pipe alignment under load

Adaptor Couplings

Flexseal Adaptor Couplings are manufactured to meet and exceed the changing requirements of the drainage marketplace. Adaptor Couplings provide a solution to connecting pipes of different outside diameters. The coupling is a stepped moulded EPDM sleeve that has different diameters at each end. The sleeve is fitted with two 1.4301 (304) stainless steel clamping bands. Adaptor Couplings can also be used to connect all traditional and new pipe systems including structural walled plastic pipes where pipes of different diameters are to be conjoined. Flexseal can also supply the product with nitrile sleeves for use with effluent which may be contaminated with hydrocarbons. Couplings are also available with Grade 1.4401 (316) stainless steel for improved corrosion protection. Like all Adaptor Couplings, Flexseal Adaptor Couplings do not meet with WIS-4-41-01 specifications. For WIS-4-41-01 applications a Flexseal Standard Coupling (SC) and a Bush (BC) should be used.

Benefits

• Provides a quick and efficient method of connecting pipes of different materials and outside diameters
• Lower cost alternative to using Bushes
• Suitable for use on any pipe material

Drain Couplings

Flexseal Drain Couplings are used to connect, repair and maintain drainage systems and other small diameter non-pressure pipelines. Available to suit any pipe material up to 275mm outside diameter, Drain Couplings are designed for use in drainage systems where the resistance to earth loads (usually provided by a Standard Coupling) is not required. Flexseal Drain Couplings comprise a moulded EPDM sleeve which is attached using Grade 1.4301 (304) wormdrive stainless steel clamping bands at either end. Flexseal can also supply the product with nitrile sleeves for use with effluent which may be contaminated with hydrocarbons. Couplings are also available with Grade 1.4401 (316) stainless steel for improved corrosion protection. Like all unshielded couplings, Flexseal Drain Couplings do not meet with WIS-4-41-01 specifications. For WIS-4-41-01 applications a Flexseal Standard Coupling (SC) should be used.

Applications

• Can be used to connect plain ended pipes
• Repair of existing pipe systems by replacing short sections of pipe
• Connects short and cut lengths of pipe
• An inexpensive option when a shielded coupling is not required

Benefits

• Low cost solution to damaged drainage systems
• Easy to install
• Efficient, airtight and watertight connection
