The Halifax HD6012 ductile iron coupling is drawn from the socketless, mechanically jointed Halifax system, joining 150mm Drain pipes and fittings without a traditional spigot and socket joint.
Construction
- Body - Two-piece coupling manufactured from ductile iron to BS EN 1563, finished in grey 2-part epoxy to match the below ground Halifax Drain range.
- Gasket - EPDM sealing gasket, tested aligned, at 3 degrees of deflection and under shear force in accordance with BS EN 877.
- Fixings - Secured with 4 zinc plated or stainless steel socket cap locking screws and nuts, using a 6mm Allen drive.
Electrical continuity
Where a continuous earth path matters, the HD6012 carries it across the joint via a grub screw on each side, tightened through the coating to bite into the metal beneath. Under independent testing at 25 Amps to BS EN 877:1999+A1:2006 Annex NA8, the resulting resistance came in below 4% of the standard's 0.3 ohm limit.
Service life
Correctly installed and maintained, cast iron drainage of this kind can remain in service for more than 100 years, and is fully recyclable without any loss of its original properties at the end of that life.
Full jointing instructions are provided in the manufacturer's Halifax Technical Guide.
