I roto i ngā rāngai he tino kaha ngā whakaritenga haumaru—pērā i te whakaputa hiko, ngā matū hinu, me te hanganga maitai—ka pā tika te kounga o ngā paipa maitai ki te huringa ora katoa o te kaupapa me te haumaru mahi. Hei kaiwhakarato paipa maitai ngaio, e mōhio ana mātou he nui atu te tiwhikete ISO 9001 i te tiwhikete noa iho; he tukanga whakapumautanga kounga whānui e kapi ana i ngā wāhanga katoa o te hanga, mai i ngā rauemi mata ki te hua kua oti. Ka tūhuratia e tēnei tuhinga ngā pūnaha whakahaere kounga me ngā paerewa paipa maitai hei whakamārama he aha ngā paipa poiha kua whakamanahia (A335raupapa),ngā ngongo tapawhā (EN10210), mengā paipa whakarewa (EN10219) te kōwhiringa pono mō ō hiahia.
I. ISO 9001: Te "Taurangi Pūnaha" o te Kounga o ngā Paipa Rino
Ko te uara matua o te pūnaha whakahaere kounga ISO 9001 kei te whakatū i tētahi tikanga PDCA (Plan-Do-Check-Act) hei whakapai tonu. Mō ngā kaihanga paipa maitai, ko te tikanga o tēnei ko ia wāhanga—mai i te hoko rauemi mata me te whakahaere tukanga whakaputa ki te tirotiro hua kua oti—ka whakahaerehia e ngā paerewa kua whakatūria, ā, e tautokona ana e ngā tuhinga ka taea te manatoko.
Me whakatinana e ngā umanga paipa rino kua whai tiwhikete i raro i te ISO 9001 he tikanga whakahaere kounga mekameka-katoa. E whakaatu ana ngā tauira ahumahi, whai muri i te whakatinanatanga o tēnei tiwhikete, kua whakaitihia e ngā kaihanga paipa whakarewa ngā reiti hapa whakarewa mai i te 2.3% ki te 0.8%, ā, kua tapahia hoki ngā utu para rauemi mata mā te 18%; mā te Whakahaere Tukanga Tatauranga (SPC), ka taea te whakau i te uara Cpk mō ngā tukanga nui ki runga ake i te 1.67. Mā ngā pūnaha whai e hiahiatia ana e te tiwhikete ka taea te aroturuki i te pito-ki-te-pito mai i ngā koiri rino rauemi mata ki ngā paipa kua oti, kia tino tika ai te whai me te whakatau i ngā take katoa i roto i ngā haora 24.
Hei tāpiritanga, ko te tiwhikete ISO 9001 he "uruwhenua" mō te whakataetae i ngā mākete o te whare me te ao, ā, ka whakakorea ngā arai ki te hokohoko o te ao. He maha ngā umanga ārahi o te ahumahi—pērā i a Hunan Shengli Xianggang Steel Pipe me Changzhou Tianzhan Steel Pipe—kua whiwhi i te tiwhikete "Integrated Management System" ISO 9001 hei whakapakari tonu i tō rātou ingoa mākete. Ko te whiriwhiri i tētahi kaiwhakarato paipa maitai kua whakamanahia ko te whiriwhiri i tētahi pūnaha whakaū kounga e tohuhia ana e te whai i ngā whakaritenga, te whakahaere tukanga, me te whakapai tonu.
Ko ngā ngongo poiha he wāhanga matua o ngā poiha tipu hiko, ngā whakamahana nui i roto i te umanga hinu matū, ngā paipa mamaoa, me ngā pūnaha paipa pēhanga teitei mō ngā taputapu hiko karihi. He paipa maitai koranu chromium-molybdenum korekore e hipokina ana e tePaerewa ASTM A335kua hangaia mō ngā āhuatanga mahi pāmahana teitei, pēhanga teitei.
Ko ngā momo A335 matua e hangaia ana e mātou ko:
A335 P11(1.25Cr-0.5Mo): He pai mō ngā pāmahana tae atu ki te 538°C pea; he whānuitia te whakamahinga i roto i ngā whakamahana nui o te poiha, ngā paipa whakamahana anō, me ngā pane tohatoha mamaoa.
A335 P22(2.25Cr-1Mo): Ka taea te mahi i ngā pāmahana tae atu ki te 580°C me ngā pēhanga ≥9.8 MPa; he ātete pai rawa atu ki te waikura hauwai, ā, koia te rauemi paerewa mō ngā pane mamaoa pēhanga-teitei i roto i ngā tipu hiko.
A335 P91(9Cr-1Mo-V-Nb): He pai mō ngā pāmahana tae atu ki te 593°C; e 2–3 ngā wā e kaha ana te ngoki atu i te P22, e āhei ai te whakaiti i te matotoru o te pakitara i raro i ngā āhuatanga hoahoa ōrite, ā, ka tino whakaiti i te taumaha o te pūnaha paipa.
Ko te hanga i ēnei ngongo poiera kounga teitei me whakahaere i ngā tukanga tino pakari. E whakamahi ana ngā ngongo poiera pēhanga-teitei A335 P91 i tētahi tukanga e toru ngā wāhanga—te rewa o te oumu hiko (EAF), te whakamahine i te oumu koko (LF), me te tango hau korehau (VD)—hei whakarite i te parakore o te maitai. Ka pā tika ngā tukanga maimoatanga wera ki ngā āhuatanga o te rauemi, ā, he mea nui te whakahaere tino pakari i runga i te whakamahana i mua me te maimoatanga wera i muri i te whakarewa. Ka whakahaerehia ēnei pūwāhi whakahaere matua katoa i raro i te pūnaha whakahaere kounga ISO 9001.
TePaerewa EN10210e tohu ana i ngā tikanga tuku hangarau mō ngā wāhanga hanganga tuwhera wera-hangaia mai i ngā maitai hanganga kore-koranu me ngā maitai hanganga pai-kiko. Ka hangaia ā mātou hua ngongo tapawhā i runga i te tino rite ki tēnei paerewa Pākehā, e kapi ana i ngā taumata rauemi pēnei i teS235JRH, S275JOH, meS355J2H.
E whakamārama ana te paerewa EN10210 i ngā whakaritenga hangarau mō ngā ine, te āhua, te taumaha, ngā āheinga, ngā āhuatanga rauemi, ngā āhuatanga miihini, me te kounga o te mata. I raro i te EN10210, ka whakahaeretia te āheinga matotoru o te pakitara i te ±1% (iti rawa ±0.5 mm), me te āheinga diameter o waho i te ±1%. He whānui te whakamahinga o ēnei hua i roto i ngā rāngai pēnei i te miihini hanganga maitai, te hanga mīhini, te hanga piriti, me ngā hanganga waka me te hanga kaipuke.
Nā te mea kei a mātou ngā tiwhikete takirua mō te ISO 9001 me te EN10210, ehara i te mea ka tutuki noa i ā mātou ngongo tapawhā ngā paerewa pakari o Ūropi mō te tika o ngā āhuatanga engari ka whai mana kounga hoki puta noa i te tukanga whakaputa katoa.
TePaerewa EN10219e kapi ana i ngā whakaritenga mō te hanganga matū, ngā āhuatanga miihini, me te whakamātautau manawanui mō ngā wāhanga maitai tuwhera kua whakarewahia i hangaia i te makariri. Kei roto i ā mātou hua paipa kua whakarewahia te whānuitanga o ngā momo rauemi, mai iS235JRHki te S460MLH.
E whakamārama ana te EN10219 i ngā whakaritenga manawanui mārama mō te diameter o waho, te matotoru o te pakitara, te roa, me te teitei o te hononga whakarewa. He rerekē ngā momo rauemi e rite ana ki ngā kaha whakaputa me ngā taumata pakari pānga; hei tauira, ka tukuna e te S235JRH he kaha whakaputa ≥235 MPa (mō te matotoru o te pakitara ≤16 mm), i te meaS355J2He whakarato ana i te pakari pānga o ≥27 J i te -20°C.
Ko ngā umanga kua whai tiwhikete ISO 9001 ka kite i te pikinga 12%–15% o te reiti paahitanga o ā rātou hua paipa whakarewa. E piri pono ana mātou ki te paerewa ISO 9001:2015, me te pupuri i tētahi pūnaha whakahaere kounga whānui e kapi ana i ngā tikanga kua tuhia, te whakahaere tukanga, te whakahaere rauemi, me te ine, te tātari, me te whakapai ake, me te whakarite kia tutuki i ia paipa whakarewa EN10219 ngā paerewa o te ao.
V. He aha mātou i whiriwhiri ai?
Whakapūmau Pūnaha: Ka whakatinanahia e mātou te pūnaha whakahaere kounga ISO 9001, me te whakarite kia whakahaeretia katoatia mai i te hoko rauemi mata ki te tukunga o ngā hua kua oti. Ngā Paerewa Whānui: Ka kapi i tā mātou whānuitanga hua ngā paerewa o te ao, tae atu ki te ASTM A335 (ngā ngongo kohua), EN10210 (ngā wāhanga tapawhā tuwhera kua oti te whakamahana), me te EN10219 (ngā wāhanga tuwhera kua whakarewaina matao).
Te Aroturuki Katoa: Ka puritia ngā rekoata whakaputa me ngā kōnae kounga katoa mō ia puranga, kia mōhio ai ka taea te aru i te hua puta noa i te tukanga.
Manatoko Tuatoru: Kei te wātea ngā tiwhikete rauemi e tutuki ana i ngā paerewa EN 10204 3.1, 3.2 rānei, e whakamana ana i te 100% o te tutuki i ngā whakaritenga mō te hanganga matū me ngā āhuatanga hangarau.
I te wā e whiriwhiri ana i ngā ngongo poiha, i ngā wāhanga tapawhā hanganga tuwhera, i ngā paipa whakarewa rānei, ehara te tiwhikete ISO 9001 i te mutunga—engari ko te tīmatanga o tā mātou whakapau kaha ki te kounga. Ko te whiriwhiri i a mātou ko te whakapūmau i te tautoko a tētahi pūnaha whakaū kounga kua whakamanahia e te ao.
Whakapā mai ki a mātou mō ngā taipitopito taipitopito o te hua me ngā tiwhikete kounga—tukuna ngā paerewa kia kōrero, ā, waiho mā te kounga e whakamatau.
