He aratohu hangarau tēnei mā ngāS460NHngā wāhanga hanganga kōhao maitai waro (SHS, RHS, me te CHS) i hangaia i raro i teEN 10210paerewa.
Tuhipoka Hira:He maitai hanganga āhua noa, he kaha teitei te S460NH. EHARA i te maitai kore waikura. I roto i ngā taiao waikura, i ngā taiao moana rānei, me whakamahi i tētahi pūnaha paninga ngaio, pērā i te pūnaha epoxy C5-M.
1. He aha te S460NH? (Te Wetewete i te Tau)
He mea hanga te S460NH mō ngā tono kawenga nui, ā, kāore e taea te tautohetohe i te pono o te hanganga. He māmā noa iho tōna tohu:
| Tohu | Te tikanga |
|---|---|
| S | Rino Hanganga |
| 460 | Te Kaha Hua Iti rawa o460 MPa(i te t ≤ 16mm) |
| N | Kua Whakaōritea (Hanganga angiangi mō te pakari) |
| H | Wāhanga Poka |

3. Te Hanga me te Whakarewa: Te Painga "Ārai-Whakapohehe"
Ko tētahi o ngā rerekētanga nui o te EN 10210 S460NH kua oti te whakamahana ki ngā wāhanga kua oti te hanga mātao ko tōna pumau hanganga ā-roto. Mā te whai i te whakatikatika tinana katoa kua whakahaeretia, ka whakakorea e mātou ngā ahotea toenga o roto e hua ai te "pūnga-muri" me te takai, kia tino tika ai te whakauru.
Akoranga Take: Hanganga o Tāwāhi
- Ngā Kaupapa Piriti o te Moana-a-Kiwa:Mā te whakakapi i ngā wāhanga matao-hanga ki tā mātou S460NH kua whakaritea, kua tutuki i ngā kiritaki he40% te whakaiti i te wā whakatikatika, nā te mea ka tino ōrite te tūnga o ngā pou i te wā e huihui ana, ā, kāore e hiahiatia he whakatikatika utu nui i te wāhi.
- Ngā Tūāpapa Hau o te Moana:I roto i te hanganga o te koti hau me te wāhanga whakawhiti nui, he mea nui te manawanui hanganga. Mā tā mātou S460NH kua whakaritea ka whakaratohia te ōritetanga o te rahinga e hiahiatia ana mō ngā raina whakarewa karetao aunoa. Hei tāpiri, i te whanaketanga o ngā paerewa hau moana o Ūropi, ka piki haere te pai o tā mātou S460NH i te S460QL nā tōna taurite pai o te kaha whakarewa me te ātete ki te ngenge.
Te Tika i roto i te Whakarewa Taiepa Taumaha
Haunga ngā hanganga piriti me te hau, ka horapa tēnei ariā hanga ki ngā taputapu taumaha katoa. He rerekē ki ngā hua hau-whakamatao paerewa, ka whakatauritehia e tā mātou huringa oumu e whakahaeretia ana te pāmahana te hanganga o te witi, ka whakaitihia te ahotea toenga o roto neke atu i te 60%. Mā tēnei ka nui ake te ātete o ō hononga ātete-teitei ki te pakaru makariri me te pakarukaru.
4. Whakatūpato Kaihoko B2B: Te karo i te S460NH "Tūpā"
⚠️ WHAKATŪPATO HANGANGA HIRAHIRA: Kaua e hoko i te “S460NH” he rite te mahi ki te maitai ngawari.
He maha ngā kaiwhakarato e tārua-whakapiri ana i ngā raraunga mai i te maitai ASTM A106B, S235 rānei noa, e whakaatu ana i te kaha tukua ngoikore o te 240 MPa anake, iti iho rānei.Ka kore e angitu tēnei i roto i tō arotake hanganga.
Rārangi Arowhai a te Tohunga mō te Hoko:
- ✓1. Manatokohia te Hua:Me whakarite kia whakaatuhia te MTC460 MPahei kaha tuku turanga.
- ✓2. Tirotiro i te koranu iti:RapuaNb(Niobium) meV(Vanadium) i roto i te pūrongo matū. Koinei ngā kai "huna" e hoatu ana ki te maitai tōna pakari ki te whakamahine i te witi.
- ✓3. Manatoko Motuhēhēnga Puranga:Me tono tonu kia whakauruhia he waehere QR haumaru, he hononga manatoko hihiri rānei ki te tiwhikete. Mā tēnei ka taea e tō rōpū whakahaere kounga te aromatawai tonu i te pono o te puranga whakaputa motuhake, ā, ka ārai i te whakarerekētanga o ngā tuhinga.
