SSAW(sidoo kale loo yaqaanSAWHDhuumaha birta waxa loola jeedaa tolmo tolsan oo dhuudhuuban oo qarqadda birta alxanka leh.
Habka wax-soo-saarka ee tuubada birta ee noocan ah waxay ku lug leedahay in si joogto ah loo curyaamiyo taarikada birta oo loo sameeyo qaab wareeg ah iyo alxanka cidhifyada taarikada iyadoo la isticmaalayo alxanka qulqulka gudaha iyo dibadda si loo sameeyo tolmo alxan oo wareeg ah oo tuubada ah.
Noocaan tuubooyinka birta ah waxaa lagu gartaa in uu leeyahay tolida alxanka, iyo waxtarkeeda sare ee wax soo saarka ayaa ka dhigaya mid ku habboon soo saarista tuubooyinka birta ee ballaaran.
Botop Steel waa soo saaraha tuubooyinka birta ee alxanka leh iyo alaab-qeybiye ka socda Shiinaha, oo bixiya heerar kala duwan iyo cabbirro tuubo bir ah oo loo habayn karo si loo buuxiyo shuruudaha mashruuca.
Alaabta birta ee SSAW ee aan bixin karno waxaa ka mid ah dhuumaha birta ah ee spiral ee API 5L, ASTM A252, EN 10217, GB/T 9711, iyo heerar kale oo badan.Intaa waxaa dheer, waxaan bixinaa tiro adeegyo ah oo ay ku jiraan farsamaynta tuubooyinka birta, flanging, qalabka tuubooyinka, dahaarka, toogashada toogashada, iyo in ka badan.
Faa'iidada gaarka ah ee tuubooyinka SSAW waa awoodda ay ku soo saari karaan tuubooyinka waaweyn ee dhexroorka ah ilaa 3,500 mm, taas oo aan suurtagal 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 tuubooyinka dhererka shakhsi ahaaneed, iyo codsiyo kala duwan.
Wax soo saarka tuubada birta ee SSAW waa nidaam aad u iswada, kaas oo aan si weyn u wanaajineynin wax soo saarka birta birta, laakiin sidoo kale waxay hubisaa heerka tayada sare ee alaabta.
SSAW mararka qaarkood waxaa loo yaqaanDSAWsababtoo ah habka alxanka waxaa lagu sameeyaa iyadoo la adeegsanayo tignoolajiyada alxanka arc laba-geesoodka ah.
