Ipayipi lensimbi le-ERW
Ipayipi le-ERW (ipayipi elihlanganisiwe elinokumelana nogesi) kanye nepayipi le-CDW (ipayipi elihlanganisiwe elidonswe ngokubandayo) kuyizinqubo ezimbili ezihlukene zokukhiqiza zamapayipi ensimbi ahlanganisiwe.
1. Inqubo yokukhiqiza
| Izinto zokuqhathanisa | Ipayipi le-ERW (ipayipi elihlanganisiwe lokumelana nogesi) | Ipayipi le-CDW (ipayipi elihlanganisiwe elidonswe ngokubandayo) |
| Igama eligcwele | Ipayipi Elihlanganisiwe Lokumelana Nogesi | Ipayipi Elihlanganisiwe Elidonswe Ngobandayo |
| Inqubo yokwakha | Unqenqema lwepuleti lensimbi lushiswa ngamandla kagesi aphezulu futhi lucindezelwe futhi luhlanganiswe lube sesimweni esihle | Kuqala kufakwe amapayipi, bese kudonswa kubanda (ukwelashwa kokuguqulwa kubanda) |
| Indlela yokushisela | Ukushisela Ukumelana Nemvamisa Ephakeme (HFW/ERW) | Ukushisela i-ERW noma i-argon arc (TIG) kuvame ukusetshenziselwa ukushisela |
| Ukucubungula okulandelayo | Ukulinganisa kanye nokusika ngqo ngemva kokushisela | Ukuqeda ukudweba okubandayo (ukugoqa okubandayo) ngemva kokushisela |
2. Izici zokusebenza
Ipayipi le-ERW
Ukunemba kobukhulu: Okuvamile (± 0.5% ~ 1% ukubekezelelana kobubanzi bangaphandle)
Ikhwalithi yobuso: I-weld isobala kancane futhi idinga ukupholishwa
Izakhiwo zemishini: Amandla ancike ezintweni eziyinhloko, futhi kungase kube nokuthamba endaweni yokushisela
Ukucindezeleka okusele: Okuphansi (ukwelashwa kokushisa okulula kuphela ngemva kokushisela)
Ipayipi le-CDW
Ukunemba kobukhulu: kuphezulu kakhulu (ngaphakathi kuka-±0.1mm, kufanelekile ngezinhloso zokunemba)
Ikhwalithi yobuso: ubuso obubushelelezi, akukho silinganiso se-oxide (esicwebezelisiwe ngemva kokudweba okubandayo)
Izakhiwo zemishini: ukuqina kokusebenza okubandayo, amandla akhuphuke ngo-20% ~ 30%
Ukucindezeleka okusele: okuphezulu (kuyadingeka ukubopha ukuze kuqedwe ukucindezeleka kokudonsa okubandayo)
3. Izimo zohlelo lokusebenza
I-ERW: amapayipi kawoyela/igesi, amapayipi esakhiwo sesakhiwo (i-scaffolding), amapayipi oketshezi anomfutho ophansi (GB/T 3091)
I-CDW: amasilinda e-hydraulic, izingxenye zomshini eziqondile (njengemikhono yokuthwala), imiphini yokudlulisa imoto (izindawo ezinezidingo zokunemba okuphezulu)
Izindinganiso ezivamile zezinhlobo
I-ERW: I-API 5L (ipayipi lepayipi), i-ASTM A53 (ipayipi lesakhiwo), i-EN 10219 (ipayipi elihlanganisiwe elijwayelekile laseYurophu)
I-CDW: I-ASTM A519 (ipayipi elidonswa ngokunembile elibandayo), i-DIN 2391 (ipayipi elijwayelekile laseJalimane elinokunemba okuphezulu)
Ipayipi le-CDW = ipayipi le-ERW + umdwebo obandayo, onezilinganiso eziqondile kanye namandla aphezulu, kodwa futhi nezindleko eziphakeme.
Ipayipi le-ERW lifanelekela izinjongo ezijwayelekile zesakhiwo, kuyilapho ipayipi le-CDW lisetshenziswa emkhakheni wemishini enembile kakhulu.
Uma ukusebenza kwepayipi le-CDW kudinga ukuthuthukiswa okwengeziwe, ukwelashwa kokunamathisela kungangezwa (ukuqeda ukucindezeleka kokusebenza okubandayo).
