Kupu Whakataki
Puta noa i ngā rāngai kohua, whakawhiti wera, oko pēhanga me ngā paipa tukatuka hinu i Ūropi me te ao whānui,EN 10216ko te paerewa Pākehā whakakotahi e whakamahia whānuitia ana mō ngā paipa maitai kore-tuitui mō ngā take pēhanga. I roto i ngā reanga katoa,P235GHmeP265GH— ko ngā momo matua e rua o te pāmahana teitei kore-konumohe — e tuku ana i te mahi ōrite engari he rerekē te whakatauranga. Ka pā tika te kōwhiringa whakatauranga hē ki te utu kaupapa me te haumaru whakahaere.
Hei kaihoko ngaio mō ngā paipa rino ahumahi, kei te pupuri a SANONPIPE i tētahi rārangi katoa o ngā paipa kore-konumohe raupapa EN 10216 e kapi ana i ngā momo kore-konumohe me ngā momo konumohe katoa. Ka wetewetehia e tēnei tuhinga ngā rerekētanga matua i waenga i te P235GH me te P265GH, ā, ka whakamāramahia ngā arowhai hoko matua hei whakarato i ngā aratohu whiriwhiri mārama mō ngā tīma hangarau me ngā tīma hoko.
Tirohanga Whānui o te Paerewa EN 10216
EN 10216Ngā ngongo maitai kore-tuitui mō ngā take pēhangahe paerewa Pākehā kotahi e whakaatu ana i ngā tikanga tuku hangarau mō ngā paipa pēhanga kore hononga puta noa i ngā awhe pāmahana rerekē. Kua whakarārangihia kia maha ngā wāhanga:
- EN 10216-1Ngā ngongo maitai kore-konumohe me ngā āhuatanga pāmahana rūma kua tohua, ngā taumata kounga TR1/TR2, mō ngā tono pēhanga whānui
- EN 10216-2Ngā ngongo maitai kore-konumohe me te konumohe mō te mahi pāmahana teitei, te karaehe kounga GH, mō ngā kohua, ngā whakawhiti wera me ngā tono pāmahana teitei
- EN 10216-3Ngā ngongo maitai angiangi mō te mahi pāmahana iti
- EN 10216-4Ngā ngongo maitai koranu
Ngā māka GH(te akomanga pāmahana teitei) kua hangaia mō te ratonga pāmahana teitei tonu. Me whakarewa te maitai kua mate me te whakamahana i te wera kia rite, me te kaha pāmahana teitei me ngā āhuatanga ngoki kua whakamanahia, ka waiho hei whiringa paerewa mō ngā ngongo poiha, ngā ngongo whakawhiti me ngā anga oko pēhanga.
Whakataurite i te Taumata Matua: P235GH vs P265GH
He momo pāmahana teitei kore-konumohe te P235GH me te P265GH i raro i te EN 10216-2. E tohu ana ngā tau i te kaha whakaputa iti rawa i roto i te MPa. E whakaatu ana ngā momo e rua i ngā rerekētanga mārama i roto i te matū, te mahi me te tono.
1. Whakataurite i te Hanganga Matū
| Huānga | Tepe P235GH | Tepe P265GH | Rerekētanga Matua |
|---|---|---|---|
| Waro (C) | ≤0.16% | ≤0.20% | He nui ake te waro i roto i te P265GH ka nui ake te kaha engari he iti ake te kaha whakarewa |
| Hiraka (Si) | ≤0.35% | ≤0.40% | Ka mate rawa ngā mea e rua; ka whakapai ake te Si teitei ake i roto i te P265GH i te ātete ki te waikura pāmahana teitei. |
| Manganēhi (Mn) | ≤1.20% | ≤1.40% | Ka whakanui ake te Mn teitei i roto i te P265GH i te kaha mā te whakapakari i te otinga totoka |
| Whēkau / Whāwhā (P/S) | ≤0.025% / ≤0.010% | ≤0.025% / ≤0.010% | Ko ngā rohe toenga pakari i ngā taumata e rua ka whakarite kia pakari te pāmahana me te ātete ki te riri |
| Ngā toenga (Cr+Cu+Mo+Ni) | ≤0.70% | ≤0.70% | Te whakahaere toenga kotahi mō te kounga rauemi ōrite |
2. Whakataurite i ngā Āhuatanga Ā-ringa (Pāmahana Rūma, t ≤ 16 mm)
| Taonga | P235GH | P265GH | Pānga ki te Tono |
|---|---|---|---|
| Kaha Hua Iti rawa | 235 MPa | 265 MPa | Ka tukuna e te P265GH te ~13% teitei ake te hua, ka taea ai te hoahoa pakitara angiangi i te pēhanga ōrite |
| Awhe Kaha Kume | 360 – 500 MPa | 410 – 570 MPa | He kaha whānui te whitiki o te P265GH ki runga, ā, he nui ake te tawhē haumaru. |
| Te roanga iti rawa | 25% | 23% | He pai ake te ngāwari o te P235GH mō te piko makariri, te whakawhanui me te hanga ngongo |
| Pānga Charpy iti rawa i te 0°C | 27 J | 27 J | He rite te pakari o te pāmahana iti, e tutuki ana i ngā whakaritenga pānga paerewa o te poihau |
| Te pāmahana ratonga tonu mōrahi | ~400°C | ~425°C | Ka mau tonu te kaha o te P265GH i te pāmahana whakarewa ~25°C teitei ake |
3. Ngā Whakamārama Tono me te Aratohu Kōwhiri
| Ahu | Pai ake te P235GH | Pai ake te P265GH |
|---|---|---|
| Te pāmahana whakahaere | ≤400°C ngā kohua pāmahana iti-ki-waenga, ngā whakawhiti pēhanga iti | Ratonga pāmahana reo-tiketike 400–425°C, ngā raina mamaoa matua pēhanga-waenga |
| Taumata Pēhanga | Ngā pūnaha pēhanga iti-ki-waenga, ngā paipa āwhina | Ngā pūtake pēhanga waenga-teitei, ngā anga me ngā pane o ngā oko pēhanga |
| Te Hanga | Ngā paihere ngongo e hiahia ana kia piko, kia whakawhanui, kia mura rānei i te makariri | Ko te nuinga he ara whakarewa tika, ko te kaha te mea nui |
| Arotahi ki te Utu | Ngā kaupapa whānui e whakatairanga ana i te whai huatanga o ngā utu | Ngā kaupapa tawhā-tiketike e whakatairanga ana i te kaha me te haumaru |
| Ngā Whakamahinga Noa | Ngā pakitara wai kohua, ngā ngongo penapena moni, ngā paihere whakawhiti wera pēhanga-iti | Ngā wāhanga whakamahana nui o te kohua, ngā pane matua o te mamaoa, ngā paipa tukatuka pēhanga-waenga matū hinu |
Ture kōwhiringa matuaKōwhiria te P235GH mō ngā pāmahana ≤400°C me ngā whakaritenga hanga teitei; whiriwhiria te P265GH mō te pēhanga teitei ake, te pāmahana teitei ake me te hanganga whakarewa matua. Ko te rerekētanga utu he tata ki te 5–8%, ā, me aromatawai tahi me te arotautanga matotoru o te pakitara.
He Kupu Whakataki Poto ki Ētahi Atu Taumata Noa
Ngā Tohu Pāmahana-Teitei Kore-Koranu
