Saldhigga Korantada Kuleyliyaha Cadaadiska Sare ee Birta Filan iyo Tubbada Usha ee 20g Birta ND
Sharaxaad Gaaban:
20G tuubo bir ah oo aan kala go 'lahayn waa bir qaabdhismeed tayo sare leh, walxo kuleyliyaha, kaarboonka 0.17-0.24%, xoogga xajinta ee 410Mpa, dhibicda 230-250Mpa.Miyuu yahay wax-soo-saarkayaga ugu weyn ee birta, waxaan ku siin karnaa 20G tuubo aan cillad lahayn oo leh tayo sare iyo qiimo tartan leh.Halkan si aan kuugu baro 20G tuubooyin aan sina lahayn sifooyinka kiimikada aasaasiga ah iyo sifooyinka farsamada.
Raadintayada weligeed ah waa hab-dhaqanka "Tixgelinta suuqa, tixgeli caadadii, tixgeli sayniska" iyo sidoo kale aragtida "tayada aasaasiga ah, rumayso kuwa ugu horreeya iyo maamulka sare" ee Saldhigga Korantada Kuleylaha ee Cadaadiska Sare ee Finned Steel Tube iyo Stud Tube ee 20g ND Steel, Waxaan had iyo jeer u aragnaa tignoolajiyada iyo macaamiisha inay yihiin kuwa ugu sarreeya.Had iyo jeer waxaan u shaqaynaa si adag si aan ugu abuurno macaamiisheena qiimo weyn oo aan u siino macaamiisheena alaab iyo adeegyo ka wanaagsan.
Ujeedadeenna weligeed ah waa hab-dhaqanka "Ixtiraamka suuqa, tixgeli caadooyinka, tixgelin sayniska" iyo sidoo kale aragtida "tayada aasaasiga ah, rumayso kan ugu horreeya iyo maaraynta sare"20g Cadaadiska Sare ee Fin Tube, Waxaan rajaynaynaa inaan aasaasno xidhiidh faa'iido u leh adiga oo ku salaysan badeecadayada tayada sare leh, qiimaha macquulka ah iyo adeegga ugu fiican.Waxaan rajeyneynaa in xalalkeena ay kuu keeni doonaan waayo-aragnimo wacan oo ay qaadaan dareenka quruxda.
