Spiral Welded Tube Arc Gusudira Imiyoboro ya gaze
Kuriumuyoboro wa gazi karemanos, umutekano no kwizerwa nibyingenzi.Gusudira kuri Arc bigira uruhare runini mukureba ko iyi miyoboro ishobora kwihanganira ibihe bibi bahura nabyo mubuzima bwabo.Igikorwa cyo gusudira arc gikubiyemo gukoresha amashanyarazi kugirango habeho ubushyuhe bwinshi bushonga impande zimiyoboro hanyuma ikabihuza hamwe.

Kimwe mu bintu by'ingenzi ugomba gusuzuma mugihe arc gusudira imiyoboro ya gazi isanzwe ni ubwoko bwa tekinike yo gusudira ikoreshwa.Kurispiral welded tubes, uburyo bukunze gukoreshwa ni tekinoroji ya arc welding (SAW).Ibi bikubiyemo gukoresha granular flux, isukwa ahantu ho gusudira kugirango habeho umwuka urinda okiside hamwe nibindi byanduza kwanduza.Ibi bivamo ubuziranenge-bwiza, busudira hamwe nudusembwa duto.
Ikindi gitekerezwaho mugihe arc gusudira imiyoboro ya gazi isanzwe ni uguhitamo ibikoresho byuzuza.Ibikoresho byuzuza bikoreshwa mukuzuza icyuho cyose cyangwa ibitagenda neza muri weld, bikora ubumwe bukomeye kandi buhoraho.Ku miyoboro isudira izunguruka, hagomba gukoreshwa ibikoresho byuzuza bihuye n’icyiciro cyihariye cy’icyuma cyakoreshejwe hamwe n’ibidukikije aho umuyoboro ugaragarira.Ibi byemeza ko gusudira gushobora kwihanganira imikazo n'ubushyuhe byatewe n'imiyoboro ya gaze gasanzwe.
Usibye ibijyanye na tekiniki yo gusudira arc, ni ngombwa nanone gusuzuma impamyabumenyi n'uburambe bw'abasudira bakora akazi.Kuzenguruka imiyoboro ya gazi isanzwe bisaba ubuhanga nubuhanga buhanitse, ndetse no gusobanukirwa neza ibibazo bidasanzwe nibisabwa akazi.Nibyingenzi gukorana nabasudira babimenyereye kandi bemewe bashobora guhora bakora ubudodo bwiza bufite ireme bwujuje ubuziranenge bwinganda.
Mu gusoza, spiral welded tube arc gusudira umuyoboro wa gaze gasanzwe nikintu cyingenzi mubikorwa byinganda.Bisaba gutekereza neza tekinike yo gusudira, ibikoresho byuzuza, hamwe nubushobozi bwabasudira bakora akazi.Mu kwemeza ko ibyo bintu byitabwaho bikwiye, bizashoboka gukora imiyoboro ya gaze isanzwe yujuje ibisabwa ninganda kugirango umutekano, kwizerwa no gukora igihe kirekire.
