Hargreaves Halifax HD6001 150mm Cast Iron Grey Double Spigot Drain Pipe 3m

The Halifax HD6001 forms part of the Halifax Drain range from Hargreaves Foundry: a 150mm double spigot pipe for buried below ground drainage and wastewater systems, jointed using a separate coupling rather than a traditional spigot and socket.

Material and coating

• Casting - Manufactured in grey cast iron to BS EN 877, with an average external epoxy coating of at least 150 microns.
• Internal coating - Minimum average 130 microns of yellow 2-pack epoxy, tested for chemical resistance between pH2 and pH12 and a 30 day waste water test at 23C.
• Length - Supplied in standard 3 metre lengths, ready to cut to size on site.

Strength below ground

Buried pipework has to withstand more than its own weight: backfill loads and, in places, traffic loading above. Cast iron consistently exceeds the ring crush strength required by BS EN 877, giving it greater resistance to crushing than PVC or HDPE alternatives of the same diameter.

Installation

• Cutting - Pipes can be cut to length on site using a powered chop saw or disc cutter fitted with a metal cutting disc; cut ends should be touched up with a high quality metal primer once burrs are removed.
• Jointing - Connects to other Halifax Drain pipes and fittings using 150mm Halifax ductile iron or push fit couplings, not a caulked socket joint.

Full dimensions, coating specifications and installation guidance are set out in the manufacturer's Halifax Technical Guide.
