Paipa raina: Hei kawe i te hinu, te hau, te wai rānei i tangohia mai i te whenua ki ngā umanga hinu me te hau mā roto i te paipa raina. Kei roto i ngā paipa raina ngā paipa kore hononga me ngā paipa whakarewa. Ko ngā pito paipa he pito papatahi, he pito miro me ngā pito pūtu; ko ngā tikanga hononga ko te whakarewa pito, te hononga hononga, te hononga pūtu, me ētahi atu.

He tirohanga whānui mō te paipa raina
Whakamahinga: Whakamahia mō te kawe hau, wai me te hinu i roto i te umanga hinu me te hau

API SPEC 5L-2018(Line pipe specification) i whakahiatohia, i whakaputaina hoki e te American Petroleum Institute, ā, e whakamahia whānuitia ana puta noa i te ao.

E ai ki ngā whakaritenga mahi rerekē oGB/T9711-2017Ko ngā paipa rino, ka taea te wehewehe i te whakamātao kia rite ki te pāmahana whakamātao:
1. Te whakamātao i te pāmahana iti (150-250 nekehanga)
Ko te hanganga i whiwhihia mā te whakamahana i te pāmahana iti ko te martensite whakamahana. Ko tōna kaupapa he whakaiti i te ahotea ā-roto me te pakarukaru o te maitai kua whakamahanahia, me te pupuri tonu i te pakeketanga teitei me te ātete kakahu teitei o te maitai kua whakamahanahia, kia kore ai e pakaru, e kino wawe rānei i te wā e whakamahia ana. Ko te nuinga o te wā e whakamahia ana mō ngā taputapu tapahi waro-nui, ngā taputapu ine, ngā paipa maitai paipa GB/T9711, ngā peera hurihuri me ngā wāhanga waro, me ētahi atu. Ko te pakeke i muri i te whakamahana he HRC58-64.
2. Te whakamahana i te pāmahana waenga (250-500 nekehanga)
Ko te hanganga i whiwhihia mā te whakamahana i te pāmahana waenga ko te troostite whakamahana. Ko tōna kaupapa he whiwhi i te kaha whakaputa teitei, te rohe ngāwari me te pakari teitei. Nō reira, e whakamahia ana mō te maimoatanga o ngā momo paipa maitai paipa GB/T9711 me ngā pokepokea mahi wera, ā, ko te pakeke i muri i te whakamahana ko te HRC35-50.
3. Te whakamātao i te pāmahana teitei (500-650 nekehanga)
Ko te hanganga i whiwhihia mā te whakamahana i te pāmahana teitei ko te troostite whakamahana. Ko te maimoatanga wera e whakakotahi ana i te tinei me te whakamahana i te pāmahana teitei e kiia ana ko te tinei me te maimoatanga whakamahana, ko te kaupapa o tēnei he whiwhi i ngā āhuatanga miihini whānui me te kaha, te pakeke, te kirihou me te pakari. Nō reira, e whakamahia whānuitia ana i roto i ngā wāhanga hanganga nui o ngā motuka, ngā paipa maitai paipa GB/T9711, ngā taputapu mīhini, me ētahi atu, pērā i ngā tokotoko hono, ngā pūtu, ngā taputapu me ngā pou. Ko te pakeke i muri i te whakamahana ko te HB200-330.

Kia mōhio: He maha ngā reta kua tāpirihia i muri i tePaerewa API 5Lte kounga maitai o te paipa, e tohu ana i ngā mea e whai ake nei:
He aha te tikanga o te paipa maitai taumata N? Ko te "N" he tohu mō te whakatikatika i te maimoatanga wera
He aha te tikanga o te paipa maitai kounga Q? Ko te tikanga o "Q" he tinei me te whakamahana i te maimoatanga wera.
He aha te tikanga o te NS mō te paipa maitai? Ko te tikanga o "NS" he whakataurite me te ātete ki te waikawa me te waikura.
He aha te tikanga o te QS, he paipa maitai? Ko te tikanga o "QS" he tinei me te whakamahana i te wera, ā, he ātete ki te waikawa me te waikura.
