This Appraisal is for a range of ECOPUR® and DUCPUR® ISO sized polyurethane lined ductile iron pipes with an elastomeric push-in TYTON JOINT in sizes DN 80 to DN 600 with 6 metre effective lengths. This Issue 3 is to replace the previous issue that had reached its 5-year expiry date.
The pipe is not OD compatible with AS/NZS 2280 pipes and fittings. Pressure classifications are specific to the nominal size of the pipe. EN 545 advises that polyurethane coating is considered as a reinforced coating and may be buried in soils of all levels of corrosivity.
ECOPUR pipes are internally lined and externally coated with polyurethane. DUCPUR pipes are internally lined with polyurethane and externally coated with metallic zinc aluminium (85/15) alloy and a blue coloured two-part epoxy finishing layer.
