Paerewa ASTM A210 Ko te paipa maitai waro waenga me ngā ngongo wera nui
| Paerewa:ASTM SA210 | Koranu, Kāore rānei: Waro maitai |
| Rōpū Tau: GrA. GrC | Taupānga: Paipa Pūwero |
| Matotoru: 1 - 100 mm | Maimoatanga Mata: Hei whakaritenga a te kiritaki |
| Diameter o Waho (Porowhita): 10 - 1000 mm | Tikanga: Hurihia Wera/Tōia Matao |
| Roa: Roa pumau, roa matapōkere rānei | Maimoatanga wera: Te whakamahana/te whakataurite |
| Āhua Wāhanga: Porowhita | Paipa Motuhake: Paipa Pakitara Matotoru |
| Te Takenga Mai: Haina | Whakamahinga: Pūwero me te Whakawhiti Wera |
| Tiwhikete: ISO9001:2008 | Whakamātautau: ET/UT |
Ka whakamahia te nuinga hei hanga i te maitai waro kounga teitei, mō ngā paipa poiha, ngā paipa wera nui
mō te umanga bolier, te paipa whakawhiti wera me ētahi atu. He rerekē te rahi me te matotoru
Te kounga teitei o te maitai pūwero waro: GrA, GrC
| Huānga | Taumata A | Tau C |
| C | ≤0.27 | ≤0.35 |
| Mn | ≤0.93 | 0.29-1.06 |
| P | ≤0.035 | ≤0.035 |
| S | ≤0.035 | ≤0.035 |
| Si | ≥ 0.1 | ≥ 0.1 |
Mō ia whakahekenga o te 0.01% i raro i te mōrahi waro kua tohua, ka whakaaetia he pikinga o te 0.06% konupora ki runga ake i te mōrahi kua tohua tae atu ki te mōrahi o te 1.35%.
| Taumata A | Tau C | |
| Kaha Kume | ≥ 415 | ≥ 485 |
| Te Kaha o te Hua | ≥ 255 | ≥ 275 |
| Te tere whakaroa | ≥ 30 | ≥ 30 |
Whakamātautau Waipūngao:
Me whakamātauria te paipa rino mā te waipēhi takitahi. Ko te pēhanga whakamātautau mōrahi he 20 MPa. I raro i te pēhanga whakamātautau, kaua e iti iho i te 10 hēkona te wā pumau, ā, kaua hoki te paipa rino e turuturu.
Kia whakaaetia e te Kaiwhakamahi, ka taea te whakakapi i te whakamātautau waipēhi mā te whakamātautau iahiko eddy, mā te whakamātautau turuturu rerenga aukume rānei.
Whakamātautau Whakapapa
Me whakamātau te whakawhāiti i ngā ngongo he nui ake te whānui o waho i te 22 mm. Kaua e kitea he wehenga, he ira mā, he poke rānei i te roanga o te whakamātautau.
Whakamātautau Mura:
E ai ki ngā whakaritenga a te kaihoko, me te mea kua whakahuatia i roto i te kirimana, ka taea te whakamātautau mura mō te paipa rino he ≤76mm te whānui o waho, ā, he ≤8mm te matotoru o te pakitara. I whakahaerehia te whakamātautau i te pāmahana rūma me te piko o te 60°. I muri i te mura, me tutuki te tere mura o te whānui o waho i ngā whakaritenga o te ripanga e whai ake nei, ā, kaua te rauemi whakamātautau e whakaatu i ngā pakaru, i ngā haehae rānei.
Whakamātautau Pakari:
Me whakahaere ngā whakamātautau pakeke o Brinell, o Rockwell rānei ki ngā tauira mai i ngā ngongo e rua o ia rota.
