Paipa maitai ERW
He rerekē ngā tukanga whakaputa e rua mō ngā paipa maitai whakarewa (ERW) me te paipa CDW (maimoa matao).
1. Tukanga whakaputa
| Ngā tūemi whakataurite | Paipa ERW (paipa whakarewa ātete hiko) | Paipa CDW (paipa whakarewa matao) |
| Ingoa katoa | Paipa Hiko Ātete Whakarewa | Paipa Whakarewa Matao |
| Te tukanga hanga | Ka whakamahanahia te taha o te pereti maitai e te iahiko auau-teitei, ka pēhia, ka whakapirihia kia rite te āhua. | I te tuatahi ka whakapirihia ki roto i ngā paipa, kātahi ka kumea mātao (maimoatanga whakarerekētanga matao) |
| Tikanga whakarewa | Te Whakarewa Ātete Auautanga Teitei (HFW/ERW) | Ko te ERW, ko te argon arc welding rānei (TIG) te tikanga e whakamahia ana mō te welding. |
| Te tukatuka i muri mai | Te rahi tika me te tapahi i muri i te whakarewa | Te whakaotinga o te tātuhi makariri (te hurihuri makariri) i muri i te whakarewa |
2. Ngā āhuatanga mahi
Paipa ERW
Te tika o te ine: Whānui (±0.5%~1% te manawanui ki te diameter o waho)
Kounga mata: He paku kitea te whakarewa, ā, me whakakanapa
Ngā āhuatanga miihini: Ko te kaha e whakawhirinaki ana ki te rauemi matua, ā, tera pea ka ngawari te wāhi whakarewa
Taumahatanga toenga: Iti (he maimoatanga wera noa iho i muri i te whakarewa)
Paipa CDW
Te tika o ngā inenga: tino teitei (i roto i te ±0.1mm, e tika ana mō ngā kaupapa tino tika)
Kounga mata: mata maeneene, kāore he unahi waikura (kua orohia i muri i te tuhi matao)
Ngā āhuatanga miihini: te whakapakeketanga o te mahi matao, te kaha kua piki ake mā te 20% ~ 30%
Te ahotea toenga: teitei (me whakamahana hei whakakore i te ahotea kukume makariri)
3. Ngā horopaki tono
ERW: ngā paipa hinu/hau, ngā paipa hanganga whare (papa), ngā paipa wai pēhanga iti (GB/T 3091)
CDW: ngā rango waipēhi, ngā wāhanga miihini tino tika (pēnei i ngā ringaringa whāriki), ngā toki tuku waka (ngā wāhi e hiahiatia ana he tika teitei o ngā āhuatanga)
Ngā paerewa noa o ngā momo
ERW: API 5L (paipa paipa), ASTM A53 (paipa hanganga), EN 10219 (paipa whakarewa paerewa Pākehā)
CDW: ASTM A519 (paipa tino tika te tōia makariri), DIN 2391 (paipa tino tika paerewa Tiamana)
Paipa CDW = paipa ERW + tārai makariri, he tika ake ngā inenga, he kaha ake, engari he nui ake ngā utu.
He pai te paipa ERW mō ngā hanganga whānui, ko te paipa CDW ia e whakamahia ana i roto i te mara o ngā mīhini tino tika.
Mena me whakapai ake te mahi a te paipa CDW, ka taea te tāpiri i te maimoatanga whakamahana (hei whakakore i te ahotea mahi matao).
