Izinhlobo Zamapayipi Ensimbi Yekhabhoni
Amapayipi ensimbi yekhabhoni angahlukaniswa ngokwezindlela zawo zokukhiqiza kanje:
1. Ipayipi Lensimbi Elingenamthungo (SMLS)
- Kwenziwe ngokubhoboza i-billet eqinile bese uyikhipha ibe yipayipi elingenalutho.
- Akukho mthungo wokushisela, uqine kakhulu ngaphansi komfutho ophezulu.
- Izicelo: Uwoyela/igesi enomfutho ophezulu, amabhoyila, izinhlelo ze-hydraulic.
2. Ipayipi Lensimbi Ehlanganisiwe
(a) Ipayipi le-ERW (eliphiniwe ngokumelana nogesi)
- Yakhiwe ngomcu wensimbi ogoqekayo kanye nemiphetho yokushisela kusetshenziswa ukumelana kukagesi.
- Umthungo oqondile, ongabizi kakhulu.
- Izicelo: Amapayipi amanzi/igesi, ukusetshenziswa kwesakhiwo.
(b) Ipayipi le-LSAW (Longitudinal Submerged Arc Welded)
- Kwenziwe ngokugoba nokushisela amapuleti ensimbi ngobude (inqubo ye-SAW).
- Umthungo owodwa oqondile, osetshenziselwa ububanzi obukhulu.
- Izicelo: Ukudluliselwa kukawoyela/igesi, amapayipi asogwini lolwandle.
(c) Ipayipi le-SSAW (elifakwe i-Spiral Arc Welded)
- Yakhiwe nge-strip yensimbi egoqekayo ngokuzungeza kanye nokushisela nge-arc engaphansi kwamanzi.
- Umthungo ogobile, ukusatshalaliswa okungcono kokucindezeleka.
- Izicelo: Amapayipi amakhulu, ukunqwabelanisa.
Amazinga Amapayipi Ensimbi Yekhabhoni
| Uhlobo | Inqubo | Isici Esiyinhloko | Izindinganiso Ezivamile |
|---|---|---|---|
