20G Seamless Steel Boiler Pipe ya dace da bututu marasa ƙarfi don yin tukunyar tukunyar tururi wanda matsin lamba ya yi girma ko sama da bututun da ba su da kyau da ake amfani da su azaman bututun mai.
20G sumul karfe bututu ne high quality-carbon tsarin karfe, tukunyar jirgi abu, da carbon abun ciki na 0.17-0.24%, tensile ƙarfi na 410Mpa, yawan amfanin ƙasa batu 230-250Mpa. Shin babban aikin mu na karfe ne, zamu iya samar da bututu mara nauyi na 20G tare da inganci mai inganci da farashin gasa. Anan don gabatar muku da mahimman abubuwan sinadarai na 20G maras sumul da kaddarorin inji.
