Mō ngā kaupapa hanga, hanganga me ngā mīhini, ka tīpakohia ngā wāhanga hanganga tuwhera i runga i te kaha, te āheinga whakarewa me te ōritetanga o ngā āhuatanga.ASTM A500 Tau Ce tohua pinepinetia ana mō aua whakaritenga nā te mea e tuku ana i te kaha teitei rawa atu o ngā paerewa A500 e whā — me te kore e neke ki te maitai koranu.Heoi, mō ngā kaihoko, kāore e ranea te tohu rauemi anake.
Ko te tūponotanga tūturu i roto i te hoko A500 Grade C ko te kore kimi i tētahi kaiwhakarato. Ko te whakarite kiate āhua o te wāhanga, te māka, te kaha tuku, te putanga whakatakotoranga me te tuhingae tutuki katoa ana ki ngā mea e hiahiatia ana e te kaupapa.
E whakamārama ana tēnei aratohu i te ASTM A500 Grade C, me pēhea te tautuhi i ngā whakaritenga kia tae atu ai ki te papaanga koia te mea i hangaia e te miihini.
1. He aha te ASTM A500 Tau C?
Ko te ASTM A500/A500M te paerewa mōngā ngongo hanganga maitai waro kua whakarewahia matao, he mea hanga-kore, he porowhita me ngā āhuaHe paerewa hanganga tēnei, ehara i te paerewa pēhanga, ā, ko te Wāhanga C tētahi o ngā wāhanga e whā e kapi ana i te whakatakotoranga kotahi.
| Taonga | Whakaritenga |
| Momo rauemi | He maitai waro (ehara i te maitai koranu, ehara i te maitai kore waikura) |
| Te Hanga | Hangaia mā te makariri, mā te whakarewa ātete-hiko (ERW) mā te hononga kore rānei |
| Ngā Āhua | Ngā āhua porowhita, tapawhā, tapawhā hāngai me ngā āhua motuhake |
| Te taha mōrahi | 88 inihi (2,235 mm) |
| Te matotoru mōrahi o te pakitara | 1.000 inihi (25.4 mm) |
| Te maimoatanga wera | Kāore e hiahiatia mō te Taumata C (ko te Taumata D anake e hiahiatia ana te maimoatanga wera) |
Nā te mea kei roto ngā Tau A, B, C me D i te whakaritenga kotahi, ka kīia he "ASTM A500"kāore e ranea i a ia anō. Ko te reta tohu me te āhua wāhanga e whakatau ana ko ēhea whakaritenga kaha e pā ana.
2. Te Kaupapa Matua e Ngarohia ana e te tini o nga Kaihoko: He Rerekē te Kaha o te Putanga o nga Ngongo Porowhita me nga Ngongo Ahua
Koinei te pūtake o te whakapoauau e tino kitea ana i roto i ngā ota ASTM A500 Grade C, me te wā e kore ai e oti te ota hoko ka kore e whakaaetia ngā rauemi.
Ka mau te taumata Ce rua ngā kaha hua iti rawa rerekē, i runga anō i te āhua, te porowhita rānei o te wāhanga.
| Taonga | Ngongo hanganga porowhita | Ngongo āhua (tapawhā/tapawhā hāngai) |
| Kaha kume, min | 62,000 psi (425 MPa) | 62,000 psi (425 MPa) |
| Te kaha o te tuku, min | 46,000 psi (315–317 MPa) | 50,000 psi (345 MPa) |
| Te toronga i roto i te 2 inihi (50 mm), min | 21% | 21% |
He kaihoko e tuhituhi ana i te "A500 Gr.C, 50 ksi te hua iti rawa" ki teporowhitaKua tohua e te ota ngongo he kaha kāore e taea te kī taurangi e te paerewa mō taua āhua. I te taha kē, he raruraru kaha tūturu tō tētahi kaupapa i hangaia ki te 50 ksi engari i tukuna mai me te karaehe porowhita C i te 46 ksi.
Ko te roanga iti rawa o te 21% e pā ana ki ngā matotoru pakitara hanganga paerewa. Mō ngā pakitara māmā ake, ka whakamahia e te whakatakotoranga he iti rawa kua tatauhia, me whakaae rānei ki te kaihanga — he mea anō hei whakaū mā te tuhituhi.
Ture whaihua: tohua ngātahitia te āhua me te kaha tuku. Kaua rawa e whakaaro ka pā tetahi ki tetahi.
3. Te Hanganga Matū o te ASTM A500 Tau C
He kaha ake te whakawhāititanga o te waro e te Wāhanga C i ngā Wāhanga B me te Wāhanga D, ā, e āhei ana hoki kia teitei ake te awhe konupora, koinei te huarahi e eke ai te wāhanga ki te kaha teitei ake, me te noho whai hua tonu ki te whakarewa.
| Huānga | Tātari wera, mōrahi | Tātari hua, mōrahi |
| Waro (C) | 0.23% | 0.27% |
| Manganēhi (Mn) | 1.35% | 1.40% |
| Whēkau (P) | 0.035% | 0.045% |
| Whānariki (S) | 0.035% | 0.045% |
| Parahi (Cu), min | 0.20% | 0.18% |
Ka pā anake te iti rawa o te parahi ina tohua te maitai parahi-mau i roto i te ota hoko. Ka taea hoki e te whakatakotoranga te tauwhitinga i waenga i te waro me te konupūmā: mō ia whakahekenga o te 0.01 ōrau i raro i te mōrahi waro kua tohua, ka taea te whakanui ake i te mōrahi konupūmā mā te 0.06 ōrau, tae atu ki ngā rohe kua tautuhia.
Nā te mea e whakahuatia ana ngā whakaritenga matū i runga i te pūtake wera me te pūtake hua, ko te tono kia kaua etātaritanga huahe mahi noa tēnei mō ngā ngongo A500.
4. ASTM A500 Tau C vs Tau A, B me D
| Tau | Kaha kume, min | Te kaha whakaputa, iti rawa (ngā ngongo porowhita) |
| Taumata A | 45,000 psi (310 MPa) | 33,000 psi (228 MPa) |
| Taumata B | 58,000 psi (400 MPa) | 42,000 psi (290 MPa) |
| Tau C | 62,000 psi (425 MPa) | 46,000 psi (317 MPa) |
| Tau D | 58,000 psi (400 MPa) | 36,000 psi (250 MPa) |
Ko te Wāhanga D te wāhanga pāmahana iti, ā, ko te wāhanga A500 anake e hiahia ana kia whakamahanatia. Ko te Wāhanga C te mea e whakarato ana i te kaha teitei rawa atu i roto i te rōpū, koinei te take matua i tohua ai mō ngā wāhanga kua utaina ina pai ake te wāhanga pakitara māmā ake.
5. ASTM A500 Tau C vs A53, A513, A1085 meEN 10210
He maha ngā pātai a ngā kaihoko mēnā ka taea te whakakapi i tētahi paerewa mō tētahi atu. Ko te tūnga tika ko te whakaū i te whakakapinga ki te whakatakotoranga o te kaupapa, kaua ki te tēpu maitai.
| Paerewa | Momo hua | Kaupapa | Rerekētanga matua mai i te A500 Grade C |
| ASTM A53 | Paipa | Ratonga pēhanga me te wai | Paipa paerewa-pēhanga, ehara i te paipa hanganga |
| ASTM A513 | Ngongo | Ngā ngongo miihini | Kua arotauhia te matū me te whakahaere ā-ahu mō ngā wāhanga mīhini kaua ki te hoahoa hanganga |
| ASTM A1085 | Ngā ngongo hanganga | Ngā wāhanga hanganga tuwhera | Whakamātautau pakari Charpy V-notch me ngā ātete pakitara me ngā kokonga kia pakari ake; Kāore e hiahiatia he whakamātautau pānga mō te A500 |
| EN 10210-1 | Ngā wāhanga tuwhera | Ngā wāhanga hanganga tuwhera kua oti te whakamahana | Te āhua matū rerekē, te manawanui me te pakari; te ara whakaoti wera o Ūropi |
| EN 10219-1 | Ngā wāhanga tuwhera | Ngā wāhanga hanganga tuwhera i hangaia i te makariri | Ko te tukanga ōrite tata rawa atu i Ūropi, engari he pūnaha tohu rerekē |
E rua ngā āhuatanga whai hua e whai ake nei i tēnei whakataurite:
●Kāore he whakaritenga ā-ture mō te pānga Charpy V-notch mō te ASTM A500 Grade C.Mēnā me whakapūmau te pakari i te pāmahana ratonga iti, tohua te ASTM A1085, tāpirihia rānei he whakaritenga pānga tāpiri ki te ota hoko A500.
●Ko ngā tohu EN 10210 / EN 10219 pēnei i te S355J2H e kiia ana he "ōrite" ki te A500 Tohu C.He rite tonu te kaha o ēnei, engari he rerekē te whakahaere i ngā rohe matū, ngā manawanui me ngā whakamātautau pānga. Whakaarohia ēnei hei whakatau tata e hiahia ana kia whakaaetia e te hangarau, kaua rawa hei whakawhitiwhiti aunoa.
