Me whai hononga kore o te paipa maitai ASTM A335.
He paipa rino te paipa maitai tui kore, kāore he hononga puta noa.
Nā te mea kāore he hononga whakarewa i roto i te hanganga o te paipa rino tuimotu, ka karohia e ia ngā tūponotanga haumaru ka pā ki ngā take kounga whakarewa. Mā tēnei āhuatanga ka taea e te paipa tuimotu te tu atu ki ngā pēhanga teitei ake, ā, mā tōna hanganga ā-roto ōrite ka whakarite kia mau tonu te kounga me te haumaru o te paipa i roto i ngā taiao pēhanga teitei.
Hei tāpiritanga, ka whakarei ake te pono o ngā ngongo ASTM A335 mā te tāpiri i ngā huānga whakarewa motuhake mō ngā āhuatanga pāmahana teitei me te pēhanga teitei.
Ko ngā momo maimoatanga wera e wātea ana mō te rauemi P9 ko te whakamahana katoa, te whakamahana isothermal rānei, me te whakataurite me te whakamahana. Ko te pāmahana whakamahana o te tukanga whakataurite me te whakamahana he 1250°F [675°C].
Ko ngā huānga whakarewa matua o te P9 koCrmeMo, he koranu chromium-molybdenum ēnei.
Kr (Kōromita)Hei huānga matua o te koranu, ka whakaratohia e te Cr te kaha tino pai ki te pāmahana teitei me te ātete ki te waikura. Ka hangaia he kiriata waikura chromium matotoru ki runga i te mata o te maitai, ka whakanui ake i te pumau me te ātete ki te waikura o te paipa i ngā pāmahana teitei.
Mo (Molybdenum)Mā te tāpiri o te Mo ka tino whakapai ake i te kaha me te pakari o ngā koranu, inā koa i ngā taiao pāmahana teitei. Ka āwhina hoki te Mo ki te whakapai ake i te kaha ngoki o te rauemi, arā, te kaha ki te ātete i te whakarerekētanga i raro i te wera roa.
Ngā Āhuatanga Kume
P5, P5b, P5c, P9,P11, P15, P21, me P22He rite tonu te kaha kume me te kaha hua.

HeKei te Ripanga 5 ngā uara iti rawa i tatauhia.
I te wā e takoto ana te matotoru o te pakitara i waenganui i ngā uara e rua i runga ake nei, ka whakatauhia te uara roa iti rawa mā te tātai e whai ake nei:
Whakaroa, P9: E = 48t + 15.00 [E = 1.87t + 15.00]
Whakawhiti, P9: E = 32t + 15.00 [E = 1.25t + 15.00]
kei hea:
E = te roa i roto i te 2 inihi, 50 mm rānei, %,
t = te matotoru tuturu o ngā tauira, inihi [mm].
Te pakeketanga
Kāore e hiahiatia he whakamātautau pakeke mō te P9.
P1, P2, P5, P5b, P5c, P9, P11, P12, P15, P21, P22, me te P921Kāore e hiahiatia he whakamātautau mārō.
Ina neke atu i te 250 mm te whānui o waho, ā, ≤ 19 mm te matotoru o te pakitara, me whakamātautau katoa mā te wai ā-pūmau.
Ka taea te tatau i te pēhanga whakamātautau mā te whakamahi i te whārite e whai ake nei.
P = 2St/D
P= te pēhanga whakamātautau wai ātete i roto i te psi [MPa];
S= te ahotea o te pakitara paipa i roto i te psi, [MPa] rānei;
t= te matotoru o te pakitara kua tohua, te matotoru o te pakitara ingoa e ai ki te tau kaupapa ANSI kua tohua, 1.143 ngā wā rānei o te matotoru iti rawa o te pakitara kua tohua, in. [mm];
D= te whānui o waho kua tohua, te whānui o waho e rite ana ki te rahi o te paipa ANSI kua tohua, te whānui o waho rānei i tatauhia mā te tāpiri i te 2t (e ai ki te whakamāramatanga i runga ake nei) ki te whānui o roto kua tohua, in. [mm].
Te wā whakamātautau: kia 5 hēkona te roa, kaua e turuturu.
Ki te kore te paipa e whakamatautauria ki te wai, me whakahaere he whakamātautau kore-whakangaro ki ia paipa hei kimi i ngā hapa.
Me whakahaere te whakamātautau kore-whakangaro o te rauemi P9 mā tētahi o ngā tikangaE213, E309 or E570.

Ngā Rerekētanga Whakaaetia o te Matotoru o te Pakitara
Kaua te matotoru o te pakitara paipa i tētahi wāhi e neke ake i te ātete kua tohua.
Ko te matotoru iti rawa o te pakitara me te whānui o waho mō te tirotiro kia tutuki ai tēnei whakaritenga mō ngā paipa i tonoa e NPS [DN] me te tau o te rārangi mahi e whakaaturia ana i roto iASME B36.10M.
Ngā ihirangi o te tohuIngoa o te kaihanga, tohu hokohoko rānei; tau paerewa; tohu; roa me te tohu tāpiri "S".
Me whakauru hoki ngā tohu mō te pēhanga wai ātete me te whakamātautau kore-whakangaro i roto i te ripanga i raro nei.
Te tohu i te wāhiMe tīmata te tohu i te 12 inihi (300 mm) mai i te pito o te paipa.
Mō ngā paipa tae atu ki te NPS 2, iti iho rānei i te 3 putu (1 m) te roa, ka taea te tāpiri i te tohu mōhiohio ki te tūtohu.
E whakamahia whānuitia ana te paipa maitai ASTM A335 P9 i roto i ngā kohua, ngā teihana hiko taputapu hinu matū, me ētahi atu, e hiahia ana ki te tu atu i te pāmahana tiketike me te pēhanga teitei nā te mea he pai ake te ātete ki te pāmahana teitei me te pēhanga teitei.
Ngā PūweroIna koa i roto i ngā paipa mamaoa matua me ngā paipa whakamahana anō o ngā poiha tino arohaehae me ngā poiha tino arohaehae mō ngā pāmahana me ngā pēhanga tino tiketike.
Ngā taputapu matū hinuPērā i ngā paipa parāoa me ngā paipa pāmahana-tiketike, e taea ai te whakahaere i ngā kohu me ngā matū pāmahana-tiketike, me whai rauemi he ātete pai ki te pāmahana me te waikura.
Ngā teihana hikoMō ngā paipa mamaoa matua me ngā whakamahana pēhanga teitei, tae atu ki ngā paipa tāpine ā-roto hei tu atu ki ngā wā roa o te pāmahana me te pēhanga teitei.
He paerewa motuhake ngā rauemi P9 i roto i ngā pūnaha paerewa ā-motu rerekē.
