SSAW(sidoo kale loo yaqaan sidaSAWH) tuubo bir ah waxaa loola jeedaa tolmo wareegsan oo la qurxiyey oo ku dhex jira tuubo bir ah oo la qurxiyey.
Habka wax soo saarka ee noocan ah ee tuubada birta ah wuxuu ku lug leeyahay in si joogto ah loo xoqo taarikada birta qaab wareegsan iyo in cidhifyada taarikada lagu dhejiyo alxanka qaansada gudaha iyo dibadda ee biyaha hoostooda ku jira si loo sameeyo tolmo alxan oo wareegsan oo loogu talagalay tuubada.
Noocan tuubo bir ah waxaa lagu gartaa inuu leeyahay tolmo alxan oo wareegsan, hufnaantiisa wax soo saar ee sarena waxay ka dhigaysaa mid ku habboon soo saarista tuubooyinka birta ee dhexroorkoodu weyn yahay.
Botop Steel waa shirkad soo saarta tuubooyinka birta ah ee la alxami karo iyo alaab-qeybiye ka socda Shiinaha, iyadoo bixisa heerar iyo cabbirro kala duwan oo tuubooyinka birta ah oo loo habeyn karo si loo daboolo baahiyahaaga mashruuca.
Badeecadaha tuubooyinka birta ah ee SSAW ee aan bixin karno waxaa ka mid ah tuubo bir ah oo wareegsan oo API 5L ah, ASTM A252, EN 10217, GB/T 9711, iyo heerar kale oo badan. Intaa waxaa dheer, waxaan bixinnaa adeegyo dhowr ah oo ay ku jiraan farsamaynta tuubooyinka birta ah, flanging, rakibaadda tuubooyinka, dahaarka, peening shot, iyo waxyaabo kaloo badan.
Faa'iidada gaarka ah ee tuubooyinka SSAW waa awoodda ay u leeyihiin inay soo saaraan tuubooyin dhexroor weyn leh oo gaaraya 3,500 mm, taas oo aan suurtogal ahayn noocyada kale ee tuubooyinka.
Intaa waxaa dheer, tuubooyinka SSAW waxay leeyihiin faa'iidooyinka xawaaraha wax soo saarka degdega ah, awoodda ay u leeyihiin inay soo saaraan tuubooyin dherer shaqsiyeed oo dheer, iyo codsiyo badan.
Soo saarista tuubooyinka birta ah ee SSAW waa hab aad u otomaatig ah, kaas oo aan si weyn u wanaajinayn waxtarka wax soo saarka tuubooyinka birta ah, laakiin sidoo kale hubinaya heerka tayada sare ee badeecada.
SSAW mararka qaarkood waxaa loogu yeeraa sidaDSAWsababtoo ah habka alxanka waxaa lagu sameeyaa iyadoo la adeegsanayo tignoolajiyada alxanka qaansada ee laba-geesoodka ah ee biyaha hoostooda ku jira.
