He Tirohanga Whānui mō te Paipa Rino Ngāwari
Ko ngā paipa rino ngāwari he paipa i hangaia ki te rino ngāwari. Ko te rino ngāwari he rino maka porowhita. Ko te nui o te pono o te rino ngāwari nā tōna kaha nui, tōna roa, me tōna ātete ki te pānga me te waikura. Ko ngā paipa rino ngāwari e whakamahia ana mō te tohatoha wai inu me te pupuhi i ngā paru, te paru me ngā matū tukatuka. Ko ēnei paipa rino he whanaketanga tika o ngā paipa rino maka o mua kua tata whakakapia inaianei. Ko te nui o te pono o ngā paipa rino ngāwari nā ōna āhuatanga pai. Ko ēnei paipa ngā paipa e tino hiahiatia ana mō ngā mahi maha.

E toru ngā momo matua o te paipa rino maka
V-2 (akomanga 40) Rino Hina, V-3 (65-45-12) Rino Mātotoru, me V-4 (80-55-06) Rino Mātotoru. He tino kaha te pēhi me te kaha ki te whakamātao i te wiri.
V-2 (akomanga 40) Rino hina, ASTM B48:
He kaha kume teitei tēnei momo, arā, 40,000 PSI, ā, he kaha pēhitanga hoki 150,000 PSI. Kei waenganui i te 187 – 269 BHN tōna pakeke. He tino pai te V-2 mō ngā mahi kakahu tika, ā, koia te mea tino kaha, te pakeke, te ātete ki te kakahu me te urupare whakamahana mō te rino hina kore-konumohe. He whānuitia te whakamahinga mō ngā mahi peera me te pū i roto i te umanga waipēhi.
V-3 (65-45-12) Rino Māeneene, ASTM A536:
Ko te kaha kume o tēnei momo he 65,000 PSI, ko te kaha hua he 45,000 PSI, me te 12% te roa. Ko te pakeke kei waenga i te 131-220 BHN. Nā tōna hanganga ferritic pai rawa atu, ko te V-3 te mea tino māmā ki te mahi miihini o ngā momo rino e toru, ā, koia tētahi o ngā momo rino tino pai rawa atu; he mea whakakotahi me te pānga pai, te ngenge, te kawe hiko me ngā āhuatanga uruhanga aukume. Ko te rino ngawari, inā koa ngā paipa, ka whakamahia nuitia mō ngā raina wai me te paru. Ka kitea hoki tēnei konganuku i roto i ngā wāhanga motuka me ngā tono ahumahi.
V-4 (80-55-06) Rino Māeneene, ASTM A536:
Ko te kaha kume o tēnei momo he 80,000 PSI, ko te kaha hua he 55,000 PSI, ā, ko te roa he 6%. Koinei te kaha teitei rawa atu o ngā momo e toru, i te mea kua whakarewaina. Ka taea te whakamahana i tēnei momo ki te kaha kume 100,000 PSI. He 10-15% te iti iho o tōna āheinga miihini i te V-3 nā tōna hanganga pearlite. He mea whiriwhiri pinepine tēnei ina hiahiatia he tauira maitai.
He pai ake ngā paipa DI i ngā paipa maitai/PVC/HDPE
• Ka penapenahia hoki e ngā Paipa DI ngā utu whakahaere i roto i ētahi huarahi tae atu ki ngā utu papu, ngā utu tā, me ngā kino pea mai i ētahi atu hanganga, ka puta ai te pakaru me te utu mō te whakatikatika whānui.
• Ko te utu mō te huringa ora o ngā Paipa DI tētahi o ōna painga nui. Nā te mea he roa te ora mō ngā whakatipuranga, he ohanga te whakahaere, he ngāwari hoki te tāuta me te whakahaere me te whai hua, he iti ake te utu mō te huringa ora mō te wā roa i tētahi atu rauemi.
• He rauemi hangarua 100% te paipa rino ngāwari.
• He kaha tōna ki te tu atu i ngā āhuatanga tino kino, mai i ngā pēhanga teitei ki ngā taumaha o te oneone me ngā kawenga waka, tae atu ki ngā āhuatanga oneone kore pumau.
• He māmā te tāutanga, ā, he haumaru hoki mō ngā kaimahi e taea ana te tapahi me te pato i te Paipa Rino Mātotoru i te papaanga.
• Nā te āhua whakarewa o te Paipa Rino Māeneene, ka taea te kimi ngāwari i te paipa i raro i te whenua mā te whakamahi i ngā taputapu kimi paipa tuku iho.
•He nui ake te kaha kume o ngā paipa DI i te maitai ngawari, ā, ka mau tonu te ātete ki te waikura o te rino maka.
