Paipa kowiri tiraārai muraHe taputapu haumaru nui tēnei mō ngā paipa tuku matū me te hinu-hau. He mea hanga ki te maitai kore waikura 316, e kapi ana i ngā rahi mai i te DN50 ki te DN300. Ko tā mātou tuku matua ko te aukati mura DN200, e whakarato ana i te tiaki pono i te ahi me te pahūtanga mō ngā pūnaha tuku wai i raro i ngā āhuatanga mahi uaua.

He maha ngā wā ka haria e ngā paipa ahumahi ngā hau mura me te kohu hinu pūngāwerewere. Mā te mura o muri me te urunga o te mura ki roto i ngā paipa ka arahi pea ki ngā aituā ahi me te pahūtanga. He ngoikore ngā ārai mura waro maitai tuku iho ki te waikura i raro i te waikura, ka whakapoto i te roa o te mahi, ā, ka puta he tūponotanga nui ki te haumaru. Koia te take he maha ngā kaupapa ahumahi e pai ake ana ki ngā ārai mura kowiri tira 316.

He tino pai ngā āhuatanga matua o tēnei raupapa ārai mura. He mea whakarewa tōna tinana matua i te maitai kore waikura 316 me te ātete pai ki te waikawa me te waikura, he pai mō ngā āhuatanga mahi hau waikura me te matū makuku. Ka taea e te whakaurunga tine mura kua whakapikohia kia tere te tine i te mura me te aukati i te horapa o te mura, me te pupuri tonu i te rere o te reo me te iti o te hekenga pēhanga. Mā te hanganga flange kua mau ki te pūtu wehewehe ka taea te wetewete ngāwari. Ka taea te tango i te wāhanga ārai mura mō te horoi me te tiaki hei whakaiti i ngā utu whakahaere. Ka taea e te hononga flanges paerewa te tāutanga ngāwari ki te papaanga me te hototahi ki ngā paerewa paipa ahumahi matua.

He painga nui tōna mō te whakamahinga. Ka ārai te mahi pono, ātete-pahū, i te hokinga mai o ngā paipa, ā, ka ārai hoki i ngā tūponotanga pahū ahi. Ka tautoko te ātete waikura pai i te mahi roa i roto i te wai moana, i te hau para matū me te hau hinu waikura, me te kore waikura, te poka rānei. He maha ngā rahi DN50-DN300 e wātea ana. Ka uru te tauira DN200 e whakamahia whānuitia ana ki te nuinga o ngā paipa rahi-waenga. Ka whakarato te hanganga pakari i te ātete pānga nui me te roa o te ora ratonga, ka whakaiti i te auau whakakapinga me te penapena i ngā whakapaunga hoko a ngā kiritaki me te ngaronga wā whakatā whakaputa.

He whānuitia te whakamahinga i roto i te kawe hinu-hau, te whakamahine hinu-matū, te maimoatanga hau para matū, ngā paipa whakaputanga tāke, te umanga matū waro me ētahi atu mara ahumahi. Hei wāhanga haumaru nui mō ngā pūnaha paipa, ka hangaia he taurangi haumaru pakari mō te tukanga whakaputa katoa.
