Dahaarka Epoxy-ku-xidhan ee Fusion iyo Dahaarka ee Dhuumaha Biyaha Birta iyo Qalabyada

Kani waa heerka Ururka Hawlaha Biyaha ee Maraykanka (AWWA).Dahaarka FBE waxaa inta badan loo isticmaalaa tuubooyinka biyaha birta ah iyo qalabyada, tusaale ahaan tuubooyinka SSAW, tuubooyinka ERW, tuubooyinka LSAW tubooyinka aan si fiican u lahayn, xusullada, tees, yareeyayaasha iwm ujeedada ilaalinta daxalka.

Dahaarka Epoxy-ku-xidhan ee Fusion-ku waa qayb ka mid ah dahaarka heerkulbeegga qalalan-budada ah, marka kulaylku shaqeeyo, soo saaro fal-celin kiimikaad dusha tuubada birta iyadoo la ilaalinayo waxqabadka hantideeda.Laga soo bilaabo 1960kii, codsigu wuxuu ku fiday cabbirada tuubooyinka sida dahaarka gudaha iyo dibadda ee gaaska, saliidda, biyaha iyo codsiyada biyaha wasakhda ah.
