More Information
The Halifax HD12048 belongs to the Halifax Drain range: a 300x250mm pipe taper, used to step a run down from 300mm to 250mm nominal bore, for example where a branch or gully feeds into a smaller diameter main run.
Construction
- Material - Produced in grey cast iron under BS EN 877, with an epoxy finish averaging no less than 150 microns.
- Jointing - The 300mm end connects using a standard 300mm Halifax coupling, and the 250mm end using a standard 250mm coupling.
Ground movement
Cast iron expands by around 0.01mm per metre for every degree Celsius rise in temperature, a coefficient close to that of concrete and steel. In practice this means a buried Halifax run moves very little relative to the ground around it, unlike some plastic systems where thermal expansion can be five to twenty times greater.
Full dimensions are set out in the manufacturer's Halifax Technical Guide.
