Paipa SSAWka hangaia mā te whakamahi i tētahi tukanga whakarewa pewa i raro i te wai e uru ana ki te hanga i tētahi koiri maitai kia porowhita, kātahi ka whakamahi i tētahi pewa whakarewa hei hono i ngā taha o te koiri.

Ko tētahi o ngā painga matua o te whakamahi i te paipa whakarewa āwhata porowhita i roto i ngā tono paipa raina API 5L ko tōna kaha ki te tu atu i ngā taumata teitei o te pēhanga o roto me waho. He mea nui rawa atu tēnei i roto i te umanga hinu me te hau, ina pāngia ngā paipa e ngā āhuatanga tino kino me ngā kawenga taumaha. Nā te hanganga kaha o ngā paipa SSAW he mea tino pai mō ngā paipa e mahi ana i ngā pēhanga me ngā pāmahana teitei, e whakarato ana i tētahi otinga pono me te roa mō te kawe i ngā rauemi utu nui.

Hei tāpiritanga, nā te ngāwari o te paipa whakarewa porowhita i raro i te pewa, he māmā noa iho te tāuta me te tiaki, ā, he kōwhiringa whai hua mō ngā kaupapa hanga paipa. Nā te kaha ki te piko me te whakarite ki ngā āhua taiao o te whenua, ka kore e hiahiatia he hanga whakaurunga ritenga utu nui, roa hoki, ā, ka whakaiti i te tūponotanga o ngā turuturu me te pakaru. Hei tāpiritanga, nā te maeneene o te mata o roto o ngā paipa SSAW ka whakaiti i te waku me te aueue, ka hua ake he rere pai ake, he iti ake hoki te whakapaunga pūngao.

a. Ko te tikanga tango-waikura e whai ake nei: FF: He maitai kua whakamatea katoatia kei roto ngā huānga here hauota i roto i ngā rahinga e ranea ana hei here i te hauota e wātea ana (hei tauira, iti rawa 0,020% Al katoa, 0,015% Al wairewa rānei). b. Kāore e pā te uara mōrahi mō te hauota mēnā he iti rawa te ihirangi Al katoa o te hanganga matū o te 0,020 % me te ōwehenga Al/N iti rawa o te 2:1, mēnā rānei he nui ngā huānga here-N kē atu kei roto. Me tuhi ngā huānga here-N ki roto i te Tuhinga Tirotiro.

Hei whakarāpopototanga, ko te whakamahinga o te paipa whakarewa porowhita i raro i te pewa i roto i ngā tono paipa raina API 5L he maha ngā painga e pai ai mō te umanga hinu me te hau. Nā tōna kaha, tōna pakari me tōna ngāwari e pai ai mō te whakamahi i roto i ngā taiao uaua, ā, nā tōna ngāwari ki te tāuta me te iti o ngā whakaritenga tiaki ka whakaratohia he otinga utu-whai hua mō ngā kaupapa hanga paipa. I te mea kei te piki haere tonu te hiahia mō te kawe pono me te whai hua o te hinu, te hau māori me te wai, kāore e taea te whakanui rawa i te hiranga o te paipa whakarewa porowhita i raro i te pewa i roto i te paerewa paipa raina API 5L. Nā tōna mahi kua whakamātauhia me tōna whānui,paipa pewa porowhita e rukuhia ana ki rarokua whakaritea kia noho tonu hei wāhanga nui o ngā hanganga e akiaki ana i te ōhanga o te ao.
