Ina aromatawaihia ngā paipa rino mō ngā whatunga hau pēhanga iti, te puna wai, ngā whatunga pupuhi ahi rānei,EN 10255He tohutoro whānui te paerewa mō te nuinga o ngā uiuinga hangarau. Mō ngā tohunga hokohoko, he mahi noa te whakataurite i ngā whakatau utu i runga i te utu mō ia tana. Heoi, i roto i te hanganga me te tāutanga mahi, ka taea e te utu tīmatanga iti ohorere te arahi ki ngā utu huna nui.
Mena ka puta he raruraru pēnei i te pakaru wawe o ngā taputapu i te wā e miro ana, ngā turuturu iti o ngā hononga, te waikura wawe rānei i ngā miro hononga, ka tere te whakakore i ngā penapena utu tuatahi mā te whakaroa i te mahi me ngā whakapaunga mahi anō. Hei rōpū hanga mohio e whakahaere ana i te tukanga katoa mai i te tukatuka maitai mata ki te whakamātautau whakamutunga, e whakapono ana mātou mā te mārama ki ētahi taipitopito whakaputa matua ka āwhina i te whakarite kia noho haumaru tō kaupapa i roto i te tahua.
He aha te take e hiahiatia ai te whakahaere pakari i te ihirangi waro mō te miro maeneene
E whakaatu ana te taitara whaimana o te whakatakotoranga EN 10255 he mea hanga motuhake ēnei ngongo mō"te whakarewa me te miro."Ahakoa tēnei whakamāramatanga mārama, he maha ngā kaihoko e kōrero ana mō ngā wheako whakarihariha i te wā e tāuta ana i te papaanga, pērā i te wiri nui o ngā mīhini miro aunoa, ngā kōtaha miro taratara, haehae rānei, me te pakaru pinepine o ngā mati tapahi utu nui.
Ko te tino take o te mate ko te pakeke rawa o te rauemi me te kore pumau o te hanganga matū.
Hei whakaiti i ngā utu whakaputa, ka whakamahia pea e ētahi kaihanga ngā momo matū noangā koiri maitaime ngā āhuatanga matū tino rerekē. Mō te mea tūturuNgā ngongo kōeke S195T, me whakahaere pai te hanganga matū mai i terauemi mataatamira:
Waro (C):Kei raro tonu i te mana pupuri0.20%
Manganēhi (Mn):Whakahaeretia i raro i te1.40%
Whēkau (P) me te Whanariki (S):Ngā rohenga mōrahi kua whakatakotoria ki0.035% / 0.030%
Mā te pupuri i te nui o te waroi raro i te 0.20%paepae, ka mau tonu te ngāwari o te maitai. Ina honoa ngā taputapu tapahi ki te paipa, ka maeneene, ka ōrite hoki te mahi a te rauemi. Mā tēnei huarahi ka tiakina ō taputapu miro mai i te pakaru wawe, ā, ka whakarite kia ma, kia hohonu hoki ngā miro e hono pai ana ki ngā hononga paerewa hei hanga i tētahi hononga pono, kāore he turuturu.
Te Ripanga Herenga OD Tino
Ina rapu ana i ngā whakatakotoranga EN 10255 i te ipurangi, he maha ngā whakarāpopototanga e wātea ana e whakaatu ana i tētahi tirohanga whānui māmā e whakaatu ana i tētahi uara whānui o waho kotahi—pērā i te 48.8 mm mō tētahi paipa DN40. Mō tētahi kaihanga kaupapa, mō tētahi kaiwhakahaere kounga rānei, kāore e ranea te whakawhirinaki noa ki tētahi tau ingoa kotahi.
Kāore te EN 10255 e mahi i runga i te manawanui e hangai ana ki te ōrau kāore i te mārama pērā i te "±1%"Nā te mea me hono pai ēnei ngongo ki ngā hononga miro, awaawa rānei kua whakaritea, ka tautuhia e te paerewa hete whānuitanga mirimita mōrahi me te iti rawamō ia rahi.
Mena ka nui ake te diameter o te paipa i te rohe o runga mā te 0.1 mm noa iho, tera pea ka kore e taea e te miro te hono tika. I tetahi atu taha, ki te whaiti rawa te diameter, kāore e ranea te hohonu o te miro ka puta, ka puta ai he hapa i te wā e whakamātautau ana i te wai. Kei raro nei ngā rohe tika e puritia ana i te wā e whakatikatika ana i ā mātou mira awheawhe:
| Rahi (DN) | Rahi Miro (Inihi) | Awhe OD Māmā (mm) | Awhe OD Waenga/Taumaha (mm) | Pakitara Mārama (mm) | Pakitara Waenga (mm) | Taiepa Taumaha (mm) | Taumaha Waenga (kg/m) |

(Tuhipoka: E ai ki ngā aratohu mana a te EN 10255, kāore he kōwhiringa raupapa Mārama mō ngā rahinga nui ake pērā i te 5″ me te 6″, e tohuhia ana e te "—" i roto i te tūtohi.)
Kawa Kounga: Te Whakapūmau i te Manatoko Matotoru Tika
E kī ana ētahi tuhinga whakatairanga he mea noa te tirotiro i te matotoru o te pakitara i roto i te pokapū o te ngongo kua oti i te wā e hanga tere ana. Mai i te tirohanga mahi, he mea kore e taea te whakahaere i te tirotiro i te maikoromita waenga-ngongo i ia oma hanga tere. Ko tā mātou tukanga manatoko kounga e arotahi ana ki tētahi tikanga mārama, whai hua, me te tino tika.
Ina tapahia e te kani rere te paipa maitai e neke ana kia roa, ka puta he koki iti me te āhua rerekē o te taha i te mata tapahi nā te kaha o te mata o te mata. Mā te whakanoho i tētahi maikiromita paerewa ki runga ake i tēnei awhi o waho ka taea te whakapohehe i te ine, i ētahi wā ka huna i te āhua o te pakitara matotoru mā te whakaatu i tētahi pānui teka, pupuhi.
Hei ārai i tēnei raruraru, kua whakangungua tā mātou tīma kounga ki te neke i te maikoromita mai i te taha tapahi kia kore ai e pāngia e ngā kōhao me te rohe whakarerekētanga o te āhua. Mā tēnei whakatakotoranga motuhake ka puta he pānui tino tika hei whakarite kia tutuki te rauemi i te paerewa -12.5% te manawanui pakitara mōrahi. Hei tāpiri, mō ngā ota miro katoa, ka whakarite mātou kia tino ma, kia maeneene hoki ngā pito o te paipa hei tautoko i te whakahaere haumaru i te wāhi me te whakahaere maeneene i ngā taputapu.
Te Piripiri Whakarewa: Te Ārai i te Pakaru o te Konutea i te Wā e Miro Ana
I roto i ngā whatunga tiaki wai me te ahi, he mea nui te ārai i te waikura o roto, o waho hoki. He tino pai te tiakitanga o te whakapūmau wera-tuku, engari he whakamātautau ā-mīhini tika i te wā tāutanga: ina tapahia e ngā tīma o te papa ngā miro, ka heua e ngā mata o te mīhini tetahi wāhanga o te maitai i te hononga. Mena kāore i te piri tika te paninga konutea, ka taea e te ahotea ā-mīhini te mea ka tihore, ka pakaru rānei te paparanga whakapūmau huri noa, pērā i te peita maroke, ka waiho te maitai o raro kia ngoikore ki te waikura wawe.
Hei whakatika i tēnei wero, ko tā mātouwhakapūmau wera-tōe arotahi ana te tukanga ki ngā tawhā kua whakatūria e teEN 10240whakatakotoranga:Konutea i roto≥55μm(me te arotahi ki tētahi mata maeneene o roto, kāore he pona konutea taratara) meKonutea i waho≥63μm.Ka aro turukihia e mātou ngā roanga horoi waikawa me ngā pāmahana o te ipu konutea me te tino tika. Mā tēnei taurite ka taea te hono pai o te konutea rewa me te turanga maitai, ka hanga he paparanga rino-konutea pumau. Ina tapahia ngā taputapu miro ki roto i te paipa, ka mau tonu te paparanga konutea ki te maitai me te kore e tihore. Ahakoa i te pūtake o ngā awaawa miro hou kua tapahia kei reira te maitai tahanga, ka whakaratohia e te paparanga konutea e karapoti ana te tiaki anodic patunga tapu, ka āwhina ki te whakaiti i te waikura mō te wā roa.
Ngā rūma whakamātautau rehu tote e aromatawai ana i ngā tauira paninga piauau wera-tuku.
Tō mātou Whakapūmautanga Kounga me te Whakatutukitanga
I roto i ngā mekameka tuku ahumahi, he mea nui te whakataurite i ngā tahua hoko me te mahi tāutanga tuturu. Ko ia whānuitanga o ngā āhuatanga, te herenga waro, me te matotoru o te paninga kua whakahuatia i runga ake nei ehara i te āhuatanga whiriwhiri; e tohu ana i tā mātou paerewa hangahanga paerewa.
