EN 10219 S275J0H me S275J2Hhe wāhanga kōhao hanganga whakarewa matao i hangaia ki te maitai kore-koranu e ai ki te EN 10219.
Ko te kaha whakaputa iti rawa o ēnei e rua he 275MPa (te matotoru o te pakitara ≤16mm). Ko te rerekētanga matua kei roto i ngā āhuatanga pānga: ko te kaha pānga iti rawa o S275J0H he 27 J i te 0°C, ko te kaha pānga iti rawa o S275J2H he 27 J i te -20°C.
He pai mō ngā tono i roto i ngā whare me ngā hanganga hangarau e pāngia ana e ngā kawenga mama.
Ko te BS EN 10219 te Paerewa Pākehā EN 10219 i whakaaetia e te UK.
Matotoru pakitara ≤40mm, Diameter o waho ≤2500mm.
Ko te CFCHS he whakarāpopototanga mō te Cold-Formed Circular Pocket Section.
E hipokina ana e te paerewa EN 10219 te whānuitanga o ngā āhua maitai hanganga tuwhera, tae atu ki te porowhita, te tapawhā, te tapawhā hāngai, me te porotītaha, kia rite ai ki ngā whakaritenga whakamahinga rerekē.
Botop Steelhe tohunga ki te whakarato i ngā ngongo maitai porowhita tuwhera o ngā rahi me ngā tukanga rerekē hei whakatutuki i te whānuitanga o ngā tono ahumahi, kia tutuki ai ngā hiahia motuhake o ā mātou kiritaki.
Mai i tōna whakatūnga i te tau 2014,Botop Steelkua noho hei kaiwhakarato matua o ngā paipa maitai waro i te Tai Tokerau o Haina, e mōhiotia ana mō te ratonga pai rawa atu, ngā hua kounga teitei, me ngā otinga whānui.
He maha ngā momo paipa maitai waro me ngā hua e pā ana ki te kamupene, tae atu kiSMLS, ERW, LSAW, meSSAWpaipa rino, me te rārangi katoa o ngā hononga paipa me ngā flanges. Kei roto hoki i ana hua motuhake ko ngā koranu kounga teitei me ngā maitai kore waikura austenitic, i hangaia kia tutuki ai ngā hiahia o ngā kaupapa paipa rerekē.
Kei te tumanako mātou ki te whakatū hononga mahi tahi ki a koe, me te waihanga i tētahi heke mai e whai hua ana ki te katoa.
Ka tangohia te waikura o te maitai mata mō te hanga i ngā wāhanga tuwhera matao, ā, me tutuki i a ia ngā tikanga tuku motuhake.
Ko ngā whakaritenga e tika ana mō S275J0H me S275J2H koFF(He maitai tino whakamate kei roto ngā huānga here hauota i roto i te nui e ranea ana hei here i te hauota e wātea ana (hei tauira, iti rawa 0,020% Al katoa, 0,015% Al wairewa rānei)).
Āhua tuku: Kua hurihia, kua whakaritea/kua whakaritea rānei (N) mō ngā maitai JR, J0, J2, me K2.
Ka taea te whakaputa i ngā paipa rino ki te EN 10219 e ngā mea e ruaERW(whakarewa ātete hiko) meKĪHIngā tukanga hanga (whakarewa pewa i raro i te wai).
Te whakaputanga oNgā ngongo ERWhe painga nō te tere ake, te utu iti hoki, ā, he maha ngā wā ka whiriwhiria mō ngā kaupapa e hiahia ana ki te whakaputa nui me te utu iti.
ERWKo ngā ngongo te tikanga e whakamahia ana hei whakaputa i ngā diameter iti ake me ngā matotoru pakitara angiangi ake, koKĪHIHe pai ake ngā ngongo mō ngā diameter nui ake me ngā pakitara matotoru ake. Tīpakohia te momo paipa maitai e tika ana mō tō kaupapa.
Ko ngā paipa ERW i hangaia kia rite ki te EN 10219, kāore e hiahiatia kia kutihia te whakarewa o roto.
Nā te mea ko ngā ngongo EN 10219 e whakamahia ana i roto i ngā mahi hanganga, pērā i te hanga me te miihini, he iti ake te kaha o ngā whakaritenga mō te āhua whakarewa i ērā mō ngā oko pēhanga, ngā paipa pēhanga teitei rānei. Nō reira, mena ka tutuki te kaha me te pono o te whakarewa i ngā whakaritenga o te paerewa, ka taea te whakamahi i ngā whakarewa ā-roto me te kore e tapahia atu.
Kāore e mahia he maimoatanga wera i muri mai, engari ko te āhua whakarewa pea kei roto i te āhua whakarewa, i te āhua rānei kua maimoatia ki te wera.
Tātari Maka (Hanga Matū o ngā Rauemi Mata)
Ko te uara ōrite waro mōrahi (CEV) o te S275J0H me te S275J2H he 0.40%.
Ko te S725J0H me te S275J2H me te CEV mōrahi o te 0.4% e whakaatu ana i te kaha whakarewa pai ake me te iti ake o te mōrearea o te whakapakeke me te ngatata i te wā whakarewa.
Ka taea hoki te tatau mā te whakamahi i te tātai e whai ake nei:
CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15.
Tātari Hua (Hanga Matū o ngā Hua Kua Oti)
I te wā e hangaia ana te maitai, he maha ngā take ka rerekē ai te hanganga matū, ā, ka pā pea ēnei huringa ki ngā āhuatanga me te kounga o te maitai.
Me tutuki te hanganga matū o te paipa maitai kua oti te hanga ki te hanganga matū o te whakarewanga me tōna rerekētanga e whakaaetia ana.
Ko ngā tawhā āhuatanga ā-mīhini ko te kaha tuku, te kaha kume, te roa, me te kaha pānga.
Mā te whakamahana i te pāmahana neke atu i te 580 ℃, neke atu rānei i te kotahi hāora, ka heke pea ngā āhuatanga hangarau.
Ngā Tuhipoka:
Kāore e hiahiatia he whakamātautau pānga ina iti iho i te 6mm te matotoru kua tohua.
Kāore e manatokohia ngā āhuatanga pānga o ngā ngongo kounga JR me J0 mēnā kāore i tohua.
Ka taea te whakamātautau i ngā whakarewa i roto i ngā paipa maitai ERW mā te tīpako i tētahi o ngā mea e whai ake nei: EN 10219

Te Roa o ngā Manawanui
Ka taea te whakarewa i ngā ngongo wāhanga tuwhera i hangaia kia rite ki te EN 10219.
I te wā e whakarewahia ana, ko te pakaru makariri i te rohe whakarewa te tino mōrearea, nā te mea ka piki ake te matotoru, te taumata kaha, me te CEV o te hua. Ka puta te pakaru makariri i te huinga o ngā āhuatanga maha:
te nui o te hauwai horapa i roto i te konganuku whakarewa;
he hanganga pakarukaru i te rohe e pāngia ana e te wera;
ngā kukū ahotea kume nui i roto i te hononga whakarewa.
Me maeneene te mata o te paipa rino, kia kore hoki he hapa e pā ki te mahi a te hua, pērā i ngā kapiti, ngā poka, ngā karawarawa, te waikura rānei.
E whakaaetia ana ngā puku, ngā awaawa, ngā awaawa roa pāpaku rānei i hangaia e te tukanga hangahanga, mena kei roto i te matotoru o te pakitara e toe ana te matotoru e whakaaetia ana, ka taea te tango i te hapa mā te huri, ā, ka tutuki i te matotoru pakitara kua whakatikatikaina ngā whakaritenga matotoru iti rawa.
Botop SteelEhara i te mea ko ngā ngongo maitai kounga teitei anake e tukuna ana e rātou e ai ki te EN 10219, engari he whānuitanga hoki o ngā kōwhiringa mō te paninga mata o ngā ngongo maitai hei whakatutuki i ngā hiahia motuhake o āna kiritaki i roto i ngā kaupapa hangarau rerekē. Kua hangaia ēnei paninga hei whakarei ake i te ātete ki te waikura o ngā ngongo, hei tāpiri atu i te tiakitanga, kia roa ake ai te ora o ā rātou mahi.
