Tuubooyinka naxaasta ah waxay u adkeysanayaan heerkulka sare waxaana loo isticmaali karaa meelo kala duwan.Marka la barbardhigo tan, cilladaha tuubooyinka kale ee badan ayaa muuqda.Tusaale ahaan, tuubooyinka birta ah ee galvanized ee loo isticmaalo dhismayaasha la dego waagii hore aad bay u fududahay in la miridhku sameeyo.Haddii aan la isticmaalin waqti dheer, waxaa jiri doona dhibaatooyin sida biyaha tuubada oo jaale ah iyo qulqulka biyaha yar.Waxa kale oo jira waxyaabo ay xooggoodu si degdeg ah hoos ugu dhacayaan heerkulka sare, kuwaas oo keeni kara khataro aan ammaan ahayn marka loo isticmaalo tuubooyinka biyaha kulul.Meesha dhalaalaysa ee naxaasta ayaa ah mid aad u saraysa ilaa 1083 darajo Celsius, heerkulka nidaamka biyaha kululna waa mid aan dayacnayn tuubooyinka naxaasta ah.Khubarada cilmiga qadiimiga ah ayaa 4,500 oo sano ka hor ka helay dhuumaha biyaha naxaasta ah ee Ahraamta Masar, taas oo ilaa hadda la isticmaalo.
1) Isticmaalka tignoolajiyada wax-soo-saarka shubista joogtada ah iyo duubista, nadiifinta sare, qaab dhismeedka wanaagsan, oksijiinta hoose ee hooseeya.
2) Ma jiraan daloolo, trachoma, porosity, oo leh kulayl wanaagsan oo kuleyl ah, habaysan, ductility, caabbinta daxalka iyo caabbinta cimilada.
3) Fudud in alxanka iyo naxaasta.
4) Alaabtu waxay leedahay tayada xasilloon, caabbinta cadaadiska sare, dhererka sare, iyo nadaafadda sare, buuxinta baahiyaha nadaafadda sare ee qalabka qaboojiyaha-free fluorine.
