Ibyiza byo gukoresha imiyoboro y'icyuma ikoze mu buryo bwa Spirally Welded Steel ASTM A252

Ibyiza byo gukoresha imiyoboro y'icyuma ishongeshejwe mu buryo bw'umwuka (Spirally Welded Steel PIPES) ASTM A252 Ishusho yagaragaye

Ibisobanuro bigufi:

Mu gihe wubaka imiyoboro y’inganda zitandukanye, guhitamo ibikoresho ni ingenzi cyane. Imiyoboro y’icyuma ivanze n’uruziga, cyane cyane iyo ikozwe hakurikijwe amahame ya ASTM A252, imaze kuba amahitamo akunzwe n’abantu benshi kubera ibyiza byayo byinshi.

Imwe mu nyungu z'ingenzi zo gukoresha umuyoboro w'icyuma wa ASTM A252 ukozwe mu buryo bwa spiral welded ni uko ukomera cyane kandi uramba. Iyi miyoboro ishobora kwihanganira umuvuduko mwinshi n'imitwaro iremereye, bigatuma iba nziza mu gutwara peteroli na gaze, gutwara abantu mu mazi no gukoresha imiterere yayo. Uburyo bwo gusudira mu buryo bwa spiral bukoreshwa mu gukora butuma umuyoboro uba ukomeye kandi ugororotse, bigatuma ushobora kwihanganira ibidukikije bikomeye.

Isesengura ry'ibicuruzwa

Icyuma kigomba kuba kirimo fosifero itarenze 0.050%.

Impinduka zemewe mu buremere n'ingano

Uburebure bwa buri kirundo cy'imiyoboro bugomba gupimwa ukwabwo kandi uburemere bwacyo ntibugomba gutandukana kurenza 15% hejuru cyangwa 5% munsi y'uburemere bwacyo, bubarwa hakoreshejwe uburebure bwacyo n'uburemere bwacyo kuri buri gice cy'uburebure.

Umurambararo wo hanze ntugomba gutandukana kurenza ± 1% ugereranije n'umurambararo wo hanze wagenwe

Ubunini bw'urukuta aho ari ho hose ntibugomba kurenza 12.5% munsi y'ubunini bw'urukuta bwagenwe

Uburebure

Uburebure bumwe butunguranye: 16 kugeza 25ft (4.88 kugeza 7.62m)

Uburebure bubiri butunguranye: hejuru ya 25ft kugeza 35ft (7.62 kugeza 10.67m)

Uburebure bungana: ihinduka ryemewe ± 1in

Uretse imbaraga,imiyoboro y'icyuma ishongeshejwe ku buryo bw'uruziga ASTM A252bitanga ubushobozi bwo kurwanya ingese. Ibi ni ingenzi cyane cyane ku miyoboro ihura n’ibidukikije bibi cyangwa ibintu byangiza. Irangi ririnda iyi miyoboro rirushaho kongera ubushobozi bwayo bwo kurwanya ingese, bigatuma iramba kandi igabanuka ry’ikiguzi cyo kuyibungabunga.

Byongeye kandi, imiyoboro y'icyuma ikoze mu buryo bworoshye ASTM A252 izwiho ubuhanga bwayo n'uburyo bworoshye bwo kuyishyiraho. Imiterere yayo yoroshye kuyihindura kugira ngo ihuze n'ibikenewe mu mushinga runaka, mu gihe imiterere yayo yoroheje ituma kuyitwara no kuyikoresha byoroha. Ibi bituma iba amahitamo meza ku buryo buhendutse ku bikorwa bitandukanye, kuko ishobora gushyirwaho vuba kandi neza, bigabanura igihe cy'akazi n'igihe cyo kubaka.

Indi nyungu yo gukoresha umuyoboro w'icyuma wa ASTM A252 ukozwe mu cyuma gikozwe mu buryo bwa spiral welded ni ukubungabunga ibidukikije. Ukozwe mu bikoresho bishobora kongera gukoreshwa, iyi miyoboro ishobora kongera gukoreshwa mu gihe cy'ubuzima bwayo burambye, bigabanye ingaruka zose ziterwa no kubaka no kubungabunga imiyoboro. Byongeye kandi, igihe kirekire imara ndetse n'ibisabwa bike mu kubungabunga bigira uruhare mu gutuma ibikorwa remezo birushaho kuba byiza kandi bitangiza ibidukikije.

Mu gusoza, imiyoboro y'icyuma ikoze mu buryo bw'umwuka ASTM A252 ifite inyungu nyinshi zituma iba amahitamo ya mbere mu kubaka imiyoboro. Ingufu zayo nyinshi, kuramba kwayo, kurwanya ingese, ubushobozi bwo gukora ibintu bitandukanye no kubungabunga ibidukikije bituma ikoreshwa mu buryo butandukanye mu nganda zitandukanye. Mu guhitamo iyi miyoboro, abakora imishinga bashobora kwemeza ko hari uburyo bwizewe kandi burambye bwo kuyikoresha bwujuje ibisabwa n'ubuziranenge n'imikorere myiza.
