Ukunama ibanga ryicyuma mu gukora no gutunganya ibigega bya peteroli bya API 650

Ukunama ibanga ryicyuma mu gukora ibigega bya peteroli byujuje ubuziranenge bwa API 650 ni inzira igoye isaba guhitamo ibikoresho, uburyo bwo gutunganya, gusudira, kugenzura ubuziranenge no gukurikiza ibisabwa byimiterere yujuje ubuziranenge. Ukunama ibanga ryicyuma ahanini rikoreshwa mu gutunganya ingobyi ya silinderi yurukuta rwikigega, rimwe na rimwe rikoreshwa no mu gisenge cyikigega cyangwa ibikoresho byihariye.

Uruzinduko rwa API 650 rukoreshwa ku bigega byo hejuru byicyuma bisudira, bibika peteroli, ibikomoka kuri peteroli, ibinyabutabire nibindi byamazi, umuvuduko wakazi uri hafi yumuvuduko wikirere (nturenge 2.5 psig), kandi ubushyuhe bwo gushushanya ntibusanzwe burenge 93°C (200°F).
Ibigega bigizwe nibyuma byinshi biteranyirijwe hamwe bisudira, harimo igorofa, urukuta rwikigega (ingobyi), igisenge cyikigega (igisenge gihamye cyangwa igisenge kigenda) nibindi.

Uburyo bwo kunama ibanga ryicyuma

• Intego yo kunama: Gutunganya ibyuma byibanga kugira ngo bibe ingobyi ya silinderi, ikoreshwa mu guteranya urukuta rwikigega, hagamijwe kwemeza ko umubiri wikigega ufite imiterere ya rondere.
• Ibikoresho:
  • Koresha imashini nini yo kuzinga ibyuma (plate rolling machine) cyangwa imashini yo kunama ibanga ikoresha amazi, ishobora gukoresha ibyuma binini kandi byinshi (ubugari bushobora kugera kuri 4m, ubwinshi bushobora kugera kuri 50mm).
  • Imashini yo kuzinga ibyuma igomba kugira igenzura rihanitse, kugira ngo yemeze ko ibyuma byunamiye byujuje ibisabwa bya API 650 ku bijyanye numuzingi no guhagarara (API 650 Section 7.5).

Ibisabwa ku bikoresho byibyuma

• Ibikoresho bikunze gukoreshwa ni icyuma cya karbone (nka ASTM A36, A283, A516 Gr.70) cyangwa icyuma kidakoreshwa (nka 304 cyangwa 316L, bitewe nuburyo amazi abitswe yangiza).
• Ibyuma bigomba gukurikiza ibisabwa byibikoresho biri mu mugereka wa API 650 (nka Appendix M, Q cyangwa S), hagamijwe kwemeza imbaraga zihagije, ubukana nubushobozi bwo gusudira.
• Ubwinshi bwibyuma bugenwa ningano yikigega, umuvuduko wo gushushanya, umutwaro wumutingito ningano yo kwangirika, ubusanzwe buri hagati ya 6mm na 50mm (API 650 Table 5.2a/b).
