ka mutu te awhi parera taki takirere Rahi: DN50 – DN1800 Hononga:c ka mutu te rawhiĀhuahira Hua: He taonga rere mo tenei paera parera. Tuwhera me te kati aunoa i runga i te rereketanga o te pehanga wai i te haumaru me te kore haruru me te kore e hiahiatia te mahi me te tiaki tangata. Ko te pehanga iti o te rere-i roto me te rere ka rite ki te pehanga wai. He pai te hiri mo te whakamuri kia kore e hoki mai me te kore e pakaru kia kore e rere whakamuri. Ko te painga pai ake me te pehanga nui ake. Anti-corrosion, anti-hoholo me te roa mahi mahi. Te whanui rahi me te diameter ingoa o DN50 - DN1800.
