Paipa APIHe mea nui te mahi a te API i roto i te hanganga me te whakahaere i ngā ahumahi pūngao pēnei i te hinu me te hau. Kua whakatūhia e te American Petroleum Institute (API) he raupapa paerewa pakari e whakahaere ana i ngā āhuatanga katoa o te paipa API, mai i te hanga ki te tono, kia pai ai tōna kounga me tōna haumaru.

He puranga paipa rino API 5L kua whakanohoia ngātahitia, me ngā tauira rauemi motuhake kua tohua ki runga i ngā paipa, hei tohu i te kounga teitei me te pono.

Paipa API 5LNgā Paerewa Tiwhikete

Mā te tiwhikete paipa maitai API ka whakarite kia whakaputa tonu ngā kaihanga i ngā hua e tutuki ana i ngā whakaritenga API. Hei whiwhi i te tohu API, me tutuki e ngā kamupene ētahi whakaritenga. Tuatahi, me whai pūnaha whakahaere kounga kua mahi pumau mō te iti rawa e whā marama, ā, e tutuki katoa ana ki te Whakatakotoranga API Q1. Ko te Whakatakotoranga API Q1, hei paerewa whakahaere kounga matua o te umanga, ehara i te mea ka tutuki noa i te nuinga o ngā whakaritenga ISO 9001 engari kei roto hoki ngā whakaritenga motuhake e hāngai ana ki ngā hiahia motuhake o te umanga hinu me te hau. Tuarua, me whakamārama mārama, me te tika hoki ngā kamupene i tā rātou pūnaha whakahaere kounga i roto i tā rātou pukapuka kounga, e kapi ana i ngā whakaritenga katoa o te Whakatakotoranga API Q1. Hei tāpiri, me whai ngā kamupene i ngā pūkenga hangarau e tika ana kia taea ai e rātou te hanga hua e tutuki ana i ngā whakaritenga hua API e tika ana. Hei tāpiri, me whakahaere tonu e ngā kamupene ngā arotake ā-roto me ngā arotake whakahaere i runga anō i te Whakatakotoranga API Q1, me te pupuri i ngā tuhinga taipitopito o te tukanga arotake me ngā hua. Mō ngā whakaritenga hua, me pupuri e ngā kaitono i te iti rawa i te kotahi kape o te putanga Ingarihi hou o te whakatakotoranga API Q1 me ngā whakatakotoranga hua API mō te raihana e tono ana rātou. Me whakaputa ngā whakatakotoranga hua e API, ā, me wātea mai i API, i tētahi kaituku whai mana rānei. He takahi mana pupuri te whakamāoritanga kore whakamana o ngā tuhinga API me te kore whakaaetanga a-tuhi mai i te API.

Ngā Rauemi Noa mō te Paipa Rino API

E toru ngā rauemi e whakamahia whānuitia ana i roto i ngā paipa API ko te A53, te A106, me te X42 (he momo maitai noa i roto i te paerewa API 5L). He rerekē rawa ēnei i roto i te hanganga matū, ngā āhuatanga miihini, me ngā horopaki tono, e whakaaturia ana i te ripanga i raro nei:

Momo Rauemi	Ngā Paerewa	Ngā Āhuatanga o te Hanganga Matū	Ngā Āhuatanga Mīhini (Ngā Uara Noa)	Ngā Wāhanga Matua o te Whakamahinga
Paipa Rino A53	ASTM A53	E rua ngā momo o te maitai waro, arā, ko te A me te B. Ko te nui o te waro o te taumata A he ≤0.25%, ā, ko te nui o te manganese he 0.30-0.60%; ko te nui o te waro o te taumata B he ≤0.30%, ā, ko te nui o te manganese he 0.60-1.05%. Kāore he huānga whakarewa.	Kaha Hua: Tau A ≥250 MPa, Tau B ≥290 MPa; Kaha Kume: Tau A ≥415 MPa, Tau B ≥485 MPa	Te kawe wai pēhanga iti (pēnei i te wai me te hau) me ngā paipa hanganga whānui, e tika ana mō ngā taiao kore-waikura.
Paipa Rino A106	ASTM A106	E toru ngā taumata o te maitai waro pāmahana-tiketike, arā, ko A, B, me C. Ka piki ake te nui o te waro i te taumata (Tohu A ≤0.27%, Tohu C ≤0.35%). Ko te nui o te manganese he 0.29-1.06%, ā, he tino kaha te whakahaere i te nui o te whanariki me te whākōkī.	Kaha Hua: Tau A ≥240 MPa, Tau B ≥275 MPa, Tau C ≥310 MPa; Kaha Kume: Katoa ≥415 MPa	Ko ngā paipa mamaoa pāmahana teitei me te pēhanga teitei, me ngā paipa hinu whakarewa, me tu atu ki ngā pāmahana teitei (te nuinga o te wā ≤ 425°C).
X42 (API 5L)	API 5L (Paerewa Rino Paipa Raina)	Ko te maitai kaha-teitei, he iti-koranu te nui o te waro, he ≤0.26%, ā, kei roto ngā huānga pēnei i te manganese me te silicon. I ētahi wā ka tāpirihia ngā huānga moroiti pēnei i te niobium me te vanadium hei whakarei ake i te kaha me te pakari.	Kaha Hua ≥290 MPa; Kaha Kume 415-565 MPa; Pakari Pānga (-10°C) ≥40 J	Ka taea e ngā paipa hinu me te hau māori tawhiti, inā koa ko ērā mō te kawe waka pehanga teitei me tawhiti, te tu atu ki ngā taiao uaua pēnei i te taumahatanga oneone me te pāmahana iti.

Tuhipoka Tāpiri:
Nō te pūnaha paerewa ASTM te A53 me te A106. Ko te tuatahi e aro ana ki te whakamahinga whānui i ngā pāmahana rūma, ko te tuarua ia e aro ana ki te mahi pāmahana teitei.
X42, nō tePaipa maitai API 5Lpaerewa, he mea hanga motuhake mō te kawe hinu me te hau, me te whakanui i te pakari o te pāmahana iti me te ātete ki te ngenge. He rauemi matua mō ngā paipa tawhiti.

Me whiriwhiri i runga i te aromatawai whānui o te pēhanga, te pāmahana, te waikura waenga, me te taiao o te kaupapa. Hei tauira, ko te X42 te mea pai mō te kawe hinu me te hau pēhanga teitei, ko te A106 te mea pai mō ngā pūnaha mamaoa pāmahana teitei.
