Nokuba ufuna iqela elincinci lokugcinwa kwezityalo okanye imithwalo epheleleyo yeekhonteyina kwiiprojekthi ze-EPC, sinikezela ngokuthunyelwa okudibeneyo ukunciphisa iindleko zothutho kunye nokunyuka kwekhabhoni.
Imibuzo ebuzwa qho
Umbuzo 1: Yintoni umahluko phakathi kwe-ASTM A106 kunye ne-ASME SA-106?I-ASTM A106 ngumgangatho wokuqala wezinto ezisetyenzisiweyo okhutshwe yi-ASTM International. I-ASME SA-106 yinkcazelo efanayo eyamkelweyo nepapashwe yi-ASME ukuze isetyenziswe phantsi kweKhowudi yeBoiler kunye nePressure Vessel. Kwiinjongo ezininzi ezisebenzisekayo ziyatshintshwa, kodwa i-SA-106 iyafuneka kwizixhobo zoxinzelelo ezakhiwe ngekhowudi ye-ASME.
Umbuzo 2: Ndingayisebenzisa nini iBanga C endaweni yeBanga B?Khetha i-SA-106 Grade C xa uxinzelelo kunye namaqondo obushushu okusebenza ekwicala eliphezulu lobuchule bentsimbi yekhabhoni, ngesiqhelo ingaphezulu kwe-450°C kunye noxinzelelo oluphezulu lwenkqubo. I-Grade C inika isivuno esiphezulu kunye namandla okutsalwa kubushushu obuphezulu, okwenza ukuba ifaneleke kwii-boiler headers kunye neendawo zokukhupha ii-superheater apho i-Grade B ingalinganiswanga ngokwaneleyo.
Umbuzo 3: Ngaba umbhobho we-SA-106 ungasetyenziselwa inkonzo yokucima ubushushu obuphantsi?Intsimbi yekhabhoni ye-SA-106 yenzelwe inkonzo yobushushu obuphezulu kwaye ayinasiqinisekiso sokuba inamandla okuqina kobushushu obuphantsi. Kumaqondo obushushu angaphantsi kwe--29°C, kufuneka kusetyenziswe intsimbi yekhabhoni enobushushu obuphantsi okanye i-alloy steel endaweni yoko.
Umbuzo 4: Ngaba imibhobho ye-SA-106 ifanelekile ukugalelwa nge-galvanizing?Ewe, i-SA-106 Grade B idla ngokuba yi-hot-dip galvanized yokukhusela ukugqwala kwangaphandle kwimibhobho yomphunga wangaphandle kunye namanzi. Singalungiselela i-galvanized SA-106 pipe xa siyicelile.
Isiphelo
Umbhobho wentsimbi yekhabhoni ongenamthungo we-ASME SA-106/SA-106M-2019 uhlala ungowona sisombululo sithembekileyo nesingabizi kakhulu kwiinkqubo zebhoyila ezinobushushu obuphezulu, umphunga kunye neenkqubo zepayipi. Ukusuka kwiindlela zombane zeBakala A ukuya kwiisekethe zebhoyila ezinoxinzelelo oluphezulu zeBakala C, inika ukusebenza okuqinisekisiweyo okuxhaswa ngamashumi eminyaka yokuqinisekiswa kwekhowudi ye-ASME.
