Waea Kowiri tira matao kua unuhia mō ngā puna: Aratohu Kaha Kume

Kupu Whakataki

Waea Kowiri tira matao kua unuhia mō ngā punaHe waea kowiri tira e whakapakaritia ana mā te kukume tonu i roto i ngā mate iti haere tae noa ki te tutuki i te diameter e hiahiatia ana, te kaha kume me te pāmahana o te puna. Ka whakamahia mō ngā puna kōpeketanga, ngā puna toronga, ngā puna hurihuri, ngā topenga, ngā mowhiti pupuri, ngā puka waea, ngā hononga hiko me ngā wāhanga miihini tino tika. Ko te karaehe 302, 304 rānei te whiringa tīmatanga noa mō ngā puna whānui, ko te 316 te mea pai mō te pānga ki te moana me te hauota, ā, ko te 17-7PH te mea e hiahiatia ana he kaha ake, he ātete ki te ngenge, he pumau rānei ki te pāmahana teitei.

Ngā Whakaaro Matua:Kāore e taea te whiriwhiri i te waea puna i runga i te kounga o te maitai kore waikura anake. Ko te whānui o te waea, te whānuitanga o te kaha kume, te whakaiti makariri, te mutunga o te mata, te whakarewa, te porowhita, te tika, te radius hanga me te maimoatanga i muri i te takai ka pā katoa ki te mahi a te puna. Ka taea e te kaha kume teitei ake te whakanui ake i te kaha kawenga, engari ka taea e te pakeketanga nui te whakaiti i te kaha hanga me te whakanui ake i te mōrearea o te pakaru i te wā e takai ana.

Ko te ASTM A313/A313M e tohua whānuitia ana mō te waea puna porowhita maitai kore waikura austenitic me te whakapakeke-waikura. Tērā pea ka tirohia te ISO 6931-1, EN 10270-3 me te JIS G 4314 i runga i te mākete me te hoahoa puna. Me kī mai e ngā kaihoko te paerewa katoa, te tohu, te diameter, te akomanga kume, te āhua o te mata, te puka mōkihi me ngā tuhinga tirotiro, kaua e tono noa i te "waea kore waikura mārō".

Te Hanga a te Tuhi Matao i te Kaha o te Koanga

Ka whakaitihia te whānui o te waea mā te kume makariri, me te kore e whakamahana i te rauemi ki te pāmahana whakakōkī anō. I te haerenga o te waea i roto i ia mata, ka whakanuia e te whakarerekētanga kirihou te kiato o te nekehanga i roto i te hanganga whakarewa. Ko tēnei tukanga, e kiia nei kowhakapakeketanga taumahatangamā te whakapakeketanga mahi rānei, ka whakanui ake i te kaha kume, te kaha tuku me te pakeke me te whakaiti i te roa.

Ko te nui o te whakahekenga makariri e whakatau ana i te āhua mīhini whakamutunga. Ka noho tonu te rauemi i kumea mārire kia taea te hanga, ko te waea puna-mārō i kumea pakari ka whakarato i te kaha teitei me te whakaora tere kaha. Ka whakamahia pea e te mira te whakamahana waenga ina nui rawa te whakahekenga katoa mō te raupapa tuhi kotahi.

Kāore te puna whakamutunga e whakawhirinaki ana ki te kaha kume anake. Ko ngā hapa o te mata, te ahotea toenga, te porowhita o te waea, te āhua kore-whakakorenga waro, te ōritetanga o te diameter me te kounga o te takai ka pā ki te roa o te ora o te ngenge. Ka taea e te karawarawa roa papaku te noho hei pūwāhi tīmatanga o te kapiti ngenge i roto i te puna utaina hihiri.
