EN 10219 S355J0Hhewhakarewa matao-hangapaipa maitai hanganga tuwhera kiEN 10219, me te kaha whakaputa iti rawa o355 MPa(te matotoru o te pakitara paipa ≤ 16 mm) me te kaha pānga o te iti rawa27 J i te 0°C.
He mea hanga mā te whakamahi i ngā tikanga whakarewa hiko, whakarewa pewa rānei i raro i te wai, me te kore e hiahiatia he maimoatanga wera i muri mai, he pai mō te whānuitanga o ngā tono hanganga hoahoa me te hangarau, tae atu ki ngā wāhanga hanganga nui pērā i ngā pou hei tautoko i te turanga.
Ko te BS EN 10219 te Paerewa Pākehā EN 10219 i whakaaetia e te UK.
Kei roto ko te whakarewa matao-hangaporowhita, tapawhā, tapawhā hāngai, me te porowhitangā wāhanga hanganga tuwhera.
CFCHS = wāhanga porotītaha porowhita matao-hanga;
CFRHS = wāhanga tapawhā, tapawhā whāiti rānei i hangaia matao;
He tohunga mātou ki te whakarato i te wāhanga porowhita kounga teitei (CHS) paipa rino hei whakatutuki i ō hiahia hangarau.
Te matotoru o te pakitara ≤40mm;
Porowhita: Te whānui o waho tae atu ki te 2500 mm;
Me hanga ngā wāhanga hanganga tuwhera mā tete whakarewa hiko, te whakarewa pewa ruku rānei (SAW).
E ai ki te EN 10219, me hanga ngā wāhanga tuwhera mā te matao, me te kore e whakamahanatia, engari ko ngā whakarewanga ka taea te hanga i roto i te āhua whakamahanatia, whakamahanatia rānei.
Mena ka whakamahia te hangarau whakarewa pewa ruku, ka taea te whakarōpū ki roto iLSAW(SAWL) (Te Whakarewa Āwhata Ruku Roa) meSSAW(HSAW)(Te Whakarewa Āwhata Porowhita i Runga i te Āwhata) i runga i te ahunga o te hononga whakarewa.
LSAWhe painga nui kei roto i te hanga owhānui-rahimengā paipa maitai matotoruā, he tino pai mō ngā horopaki tono e tino hiahiatia ana te kaha teitei, te kounga teitei, me ngā inenga tika.
JCOEHe tukanga tino nui, he tukanga whakaatu hoki tēnei i roto i te hanga paipa maitai LSAW. Ko te ingoa o te tukanga i ahu mai i ngā mahi matua e whā o te tukanga hanga paipa: te hanga-J, te hanga-C, te hanga-O, me te whakawhanui.
He kaihanga me te kaiwhakarato paipa maitai waro kounga teitei mātou nō Haina, ā, he kaihokohoko paipa maitai kore hononga hoki mātou, e tuku ana i te whānuitanga o ngā otinga paipa maitai ki a koe!

Tātaritanga Hua
Te tātaritanga hanganga matū o ngā wāhanga tuwhera kua oti
Ko ngā rerekētanga o te tātari hua mai i ngā rohe kua tohua mō te tātari whakarewa me rite ki ngā whakaritenga i raro nei.
Mā te whakamahana i te pāmahana neke atu i te 580 °C, neke atu rānei i te kotahi hāora, ka heke pea ngā āhuatanga hangarau.
Me whakahaere te whakamātautau kume i runga anō i ngā whakaritenga o te EN 10002-1.
Me whakahaere te whakamātautau pānga kia rite ki te EN 10045-1.
Ka manatokohia ngā āhuatanga pānga ina tohua te Kōwhiringa 1.3 anake.
c Mō ngā rahi wāhanga D/T < 15 (porowhita) me (B+H)/2T < 12,5 (tapawhā me te tapawhā hāngai) ka whakaitihia te roanga iti rawa mā te 2.
Mō ngā matotoru < 3 mm tirohia te 9.2.2.
Mō ngā āhuatanga pānga mō ngā wāhanga whakamātautau wāhanga iti, tirohia te 6.7.2.
Ngā TuhipokaKāore e hiahiatia he whakamātautau pānga ina he <6mm te matotoru kua tohua.
Me whakamātautau ngā whakarewa i roto i ngā wāhanga kōwhao i whakarewaina ki raro i te pewa kia rite ki te EN 10246-9 mō te akomanga whakaae U4, me whakamātautau rānei mā te hihi-X kia rite ki te EN 10246-10 mō te akomanga kounga whakaahua R2.

Whakamātautau Waipūmau
He maha ngā tikanga whakamātautau kore-whakangaro me ngā whakamātautau pēhanga wai-pūmau e whakamahia ana e mātou hei whakarite i te kaha me te pakari o ia paipa. Ka whakaratohia e mātou ki ō mātou kiritaki ngā hua paipa rino e tutuki ana i ngā paerewa teitei o te haumaru me te kounga.
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.
He pai ngā paipa rino EN 10219 mō te whakawerawera me te tuku wera. Ka taea te whiriwhiri i runga i ngā hiahia tūturu.
Me maeneene te mata e rite ana ki te tikanga hanga i whakamahia; ka whakaaetia ngā puku, ngā āputa, ngā awaawa pāpaku rānei i puta mai i te tukanga hanga, mena kei roto i te matotoru e whakaaetia ana.
Ka taea te tango i ngā hapa o te mata mā te huri, engari me kaua te matotoru o te wāhanga tuwhera kua whakatikatikaina kia iti iho i te matotoru iti rawa e whakaaetia ana i roto i te EN 10219-2.
