No-Hub Cast Iron Drainage system EN877

Our EN877 European Standard No-Hub Cast Iron Drainage system comprises cast iron pipes, fittings, couplings and other accessories.

Characteristics of pipework system:

	Adequate resistance to temperature change.
	Adequate resistance to waste water.
	Adequate resistance quantities of chemicals.
	Adequate resistance to the forms of loading and protected with impacts.
	There are components which help to protect the pipework system against fire.
	Cast iron provides naturally silent waste water systems, comparing other pipe materials with the same wall thickness.
	Long life expectancy.
	The system can be removed easily and replaced.

	Angular deviation must not exceed 3° and this arrangement should not be used to replace a bend, otherwise it could cause leakage.
	Pipes must be adequately supported by brackets every connection and at a maximum spacing of 2 metres. The maximum distance allowed between support bracket and coupling is 750mm.
	When inserting a junction or length of pipe into an existing pipeline, the pipe ends should be cut square. Check the cut end of pipe for sharp edges that might damage the elastomer seal in the coupling.
	It is recommended that the cut edges are coated with epoxy coating or anti-corrosive paint.
