Spiral Submerged Arc Welded Imiyoboro Yinganda Zigezweho
Ibyiza bya spiral yarengewe arc gusudira umuyoboro:
1. Kubaka neza:
Imiyoboro ya SSAW igaragaramo igishushanyo cyo gusudira cyemerera gukora neza no kugabanya igihe cyo gukora.Iyi miterere idasanzwe ituma ihitamo ryambere kumishinga minini yubwubatsi nka peteroli naimiyoboro ya gaze, uburyo bwo kohereza amazi, hamwe na platifike yo gucukura.Uburyo bukomeza bwo gusudira butanga urwego rwo hejuru rwuburinganire bwimiterere, bikongerera igihe kirekire nubuzima bwa serivise.

2. Imbaraga zidasanzwe no guhinduka:
Imiterere izenguruka umuyoboro wa SSAW yongerera imbaraga, ikayirwanya kurwanya imikazo yo hanze n'imbere.Iyi miyoboro irashobora kwihanganira imiterere yikirere ikabije, bigatuma ikwirakwira hejuru no munsi yubutaka.Byongeye kandi, guhuza imiyoboro ya SSAW ibemerera guhuza byoroshye no gushyirwaho mubutaka butandukanye, harimo n'ubutaka bubi n'ubutaka budahungabana.
3. Igisubizo cyiza:
Gukomeza gusudira bikomeza kongera umusaruro mugihe bigabanya cyane inenge yo gusudira nibiciro.Byongeye kandi, imiyoboro ya arc izengurutswe itanga imbaraga zidasanzwe kandi ziramba, kugabanya amafaranga yo kubungabunga no gusana ubuzima bwabo bwose, bigatuma bahitamo ubukungu bwinganda.
Inzitizi zihura na spiral zirengewe arc gusudira imiyoboro:
1. Kugenzura ubuziranenge:
Kubera uburyo bugoye bwo gusudira bugira uruhare mukubyara imiyoboro ya arc izengurutswe, kwemeza ubuziranenge buragoye.Niba ibipimo byo gusudira bitagenzuwe neza, inenge zo gusudira nka undercuts, pore, no kubura fusion bizabaho.Kugira ngo iki kibazo gikemuke, ingamba zikomeye zo kugenzura ubuziranenge hamwe na sisitemu zo kugenzura zigezweho mu gihe cyo gukora ni ngombwa.
2. Umuyoboro wa diameter ntarengwa:
Mugihe imiyoboro ya arc izengurutswe ni nziza kubikorwa bya diameter nini, ntibishobora kuba bibereye inganda zisaba ubunini buke.Igikorwa cyo gukora kirakora neza kumiyoboro minini ya diameter, bigatuma haboneka imishinga mito nko gutura hamwe no gukoresha inganda nto.Kubisabwa nkibyo, ubundi buryo bwo gukora imiyoboro ikora imiyoboro.
3. Igipfukisho cy'ubuso:
Iyindi mbogamizi ihura ninganda za SSAW ni ukureba neza kandi biramba hejuru yubutaka kugirango birinde kwangirika no kwambara.Gukoresha ibishishwa hejuru yumuzingi bisaba ibikoresho nubuhanga buhanitse kugirango habeho gukwirakwizwa no gufatana.Gufata neza neza ni ngombwa mu kwagura ubuzima bwa serivisi ya spiral yarengewe na arc gusudira umuyoboro, cyane cyane mubidukikije.
Mu gusoza:
Imiyoboro ya spiral yibitseho arc yasudutse yerekanye ko ari tekinoroji nziza cyane munganda zigezweho, itanga imikorere, imbaraga nigiciro-cyiza.Ikirangantego cyihariye cya spiral weld itanga umusaruro unoze kandi ikaramba, bigatuma ikorwa mumishinga minini yubwubatsi.Nyamara, kugirango ukomeze gutsinda no kwamamara cyane muri ubu buhanga bwo gukora, imbogamizi nko kugenzura ubuziranenge, ingano ya diameter ntarengwa, hamwe n’uburinganire bw’ubutaka bigomba gukemurwa.Mu gutsinda izo mbogamizi binyuze mu iterambere ry’ikoranabuhanga no mu bufatanye n’inganda, umuyoboro w’ibizenga arc welded umuyoboro ufite ejo hazaza heza mu guhindura no gukomeza ibikorwa remezo bikomeye ku isi.
