Ubwoko bw'imiyoboro y'icyuma cya karuboni
Imiyoboro y'icyuma cya karuboni ishobora gushyirwa mu byiciro hakurikijwe uburyo ikorwamo ku buryo bukurikira:
1. Umuyoboro w'icyuma utagira umushono (SMLS)
- Bikozwe no gutobora igice gikomeye cy'umugozi no kugishyira mu muyoboro w'ububobere.
- Nta mushonge wo gusudira, ukomeye cyane iyo urimo umuvuduko mwinshi.
- Ikoreshwa: Amavuta/gaze afite umuvuduko mwinshi, boilers, sisitemu za hydraulic.
2. Umuyoboro w'icyuma ushongeshejwe
(a) Umuyoboro wa ERW (Urwanya amashanyarazi)
- Yakozwe n'icyuma gizunguruka n'inkombe zo gusudira hakoreshejwe amashanyarazi.
- Umushongi ugororotse, uhendutse.
- Imikoreshereze: Imiyoboro y'amazi/gaze, imikoreshereze y'inyubako.
(b) Umuyoboro wa LSAW (Longitudinal Submerged Arc Welded)
- Byakozwe hakoreshejwe uburyo bwo kunama no gusudira ibyuma mu buryo burambuye (SAW process).
- Umushonge umwe ugororotse, ukoreshwa ku ngano nini.
- Ikoreshwa: Gukwirakwiza peteroli/gaze, imiyoboro y'amazi mu nyanja.
(c) Umuyoboro wa SSAW (Spiral Submerged Arc Welded)
- Yakozwe n'icyuma gihuza uruziga n'icyuma gisudira hakoreshejwe umugozi wo munsi.
- Umushongi wo mu gisenge, utuma imitsi ikwirakwira neza.
- Imikoreshereze: Imiyoboro minini, ikoreshwa mu gukurura.
Amabwiriza agenga imiyoboro y'icyuma cya karuboni
| Ubwoko | Inzira | Ikintu cy'ingenzi | Amahame Rusange |
|---|---|---|---|
| Nta muvuduko | Gusohora ibintu bishyushye, gushushanya ibintu bikonje | Nta gusudira, imbaraga nyinshi | ASTM A106, API 5L, ASTM A252 |
| ERW | Gusudira ubudahangarwa n'amashanyarazi | Umushono ugororotse, uhendutse | ASTM A53 (E), EN 10255, EN10219, BS1387 |
| LSAW | Gusudira arc ikoresheje uburebure bw'umurambararo | Inkuta nini, uburebure bunini | API 5L, ASTM A671, ASTM A252 |
| SSAW | Gusudira arc munsi y'amazi mu buryo bwa spiral | Umushono w'icyuma gifata imigozi, urinda imihangayiko | API 5L, ASTM A252 |
