The Halifax HD8047 forms part of the Halifax Drain range: a 200x150mm pipe taper, used to step a run down from 200mm to 150mm nominal bore, for example where a branch or gully feeds into a smaller diameter main run.
Construction
- Material - Formed from grey cast iron to the BS EN 877 specification, epoxy coated to an average minimum of 150 microns.
- Jointing - The 200mm end connects using a standard 200mm Halifax coupling, and the 150mm end using a standard 150mm coupling.
Settlement
Where pipework leaves a building or manhole and may be subject to settlement, the guide recommends at least two joints within 600mm of the exit point, acting as a short rocker pipe; the couplings used across the Halifax system are designed to accommodate up to 3 degrees of deflection, which combines with this short pipe length to absorb movement without compromising the joint.
Full dimensions are set out in the manufacturer's Halifax Technical Guide.
