Ekwakheni nasekwakheni, ukusetyenziswa kwentsimbi yentsimbi (ebizwa rhoqo i-C Ezi ndlela zenziwa ngentsimbi kwaye zibunjwe njenge-A e-C, ngenxa yoko igama. Ziqhelekile kwishishini lokwakha kwaye zinoluhlu olubanzi lokusebenzisa. Ukuqinisekisa ukuba umgangatho kunye neenkcazo zecandelo le-C-ilondolozwe, uluntu lwaseMelika luvavanyo kunye nezixhobo (i-ASTM) ziphuhlisa imigangatho yezi mveliso.
Umgangatho we-ASTMIntsimbi ebiweyoIbizwa ngokuba yi-ASTM A36. Lo mgangatho uphawula izinto ezisemgangathweni ze-carbon ye-carbon ye-carbon ukuze usetyenziswe kwi-riveted, eyakhiweyo okanye isakhiwo se-bided okanye izakhiwo kunye neenjongo zesakhiwo ngokubanzi. Lo mgangatho ucacisa iimfuno zokwenziwa, iipropathi zoomatshini kunye nezinye iimpawu ezibalulekileyo ze-C-C-C.
Enye yeemfuno eziphambili ze-ASTM A36I-C-Channel yentsimbikukwenziwa kweekhemikhali zentsimbi esetyenziswa kwimveliso yayo. Umgangatho ufuna intsimbi esetyenziselwa i-C-C-pro ukuba iqulethe amanqanaba achaziweyo ekhabhoni, Manganese, Pulfur kunye nobhedu. Ezi mfuno ziqinisekisa ukuba intsimbi esetyenziswe kwi-C-Channel ineepropathi eziyimfuneko ukubonelela ngamandla kunye nokuqhekeka okufunekayo kwizicelo zesakhiwo.
Ukongeza kubume bekhemikhali, i-ASTM A36 ichaza inkcazo yoomatshini bensimbi esetyenziswe kwi-C Oku kubandakanya iimfuno zokunqongophala, amandla e-phangend kunye ne-Elongile yentsimbi. Ezi ndawo zibalulekile ukuqinisekisa ukuba intsimbi ye-C-Channel inamandla ayimfuneko kunye nexesha lokumelana nemithwalo kunye noxinzelelo olufumaneka kwizicelo zokwakha.
Umgangatho we-A36 ophakamayo ujamelene noqingqo-mali kunye nokuchasana ngqo kunye neemfuno ze-curvature zecandelo le-C-COP. Oku kucaciswa kuqinisekisa ukuba amacandelo e-CDE oveliswe kulo mgangatho uhlangabezana nobungakanani kunye neemfuno zokuma ezifunekayo ukusetyenziswa kwabo kwiiprojekthi zokwakha.
Ngokubanzi, i-ASTM A36 yensimbi yensimbi ye-C ibonelela ngeseti lemfuno yomgangatho kunye nokusebenza kwezi ntaka. Ngokuthobela lo mgangatho, abavelisi banokuqinisekisa ukuba amacandelo e-C avelisa ihlangabezana neenkcazo ezifunekayo kwizicelo zokwakha.
Ngesishwankathelo, umgangatho we-ASTMI-C-Channel yentsimbi, eyaziwa ngokuba yi-ASTM A36, icacisa iimfuno zokwenziwa kweekhemikhali, iipropathi zoomatshini, kunye nokudakumba kwezinto zale migangatho. Ngokudibana nale mfuno, abavelisi banokuvelisa amacandelo aphezulu e-C-ekumgangatho ophezulu ohlangabezana nemigangatho eyimfuneko kwizicelo ezahlukeneyo zokwakha. Nokuba ziibhulorho, oomatshini bomzi-mveliso okanye izakhiwo, ukubambelela kwimigangatho ye-ASTM C-Icandelo liqinisekisa ukhuseleko kunye nokuthembeka kwentsimbi esetyenzisiweyo.
