Kwisakhiwo kunye nokwakhiwa, ukusetyenziswa kwentsimbi yentsimbi (ehlala ibizwa ngokuba yintsimbi ye-C-section) ixhaphake kakhulu. Ezi tshaneli zenziwe ngentsimbi kwaye zenziwe njenge-C, ngoko ke igama. Ngokuqhelekileyo zisetyenziswa kwishishini lokwakha kwaye zineendlela ezininzi zokusetyenziswa. Ukuqinisekisa ukuba umgangatho kunye neenkcukacha zentsimbi ye-C zigcinwa, i-American Society for Testing and Materials (ASTM) iphuhlisa imigangatho yale mveliso.
Umgangatho weASTM weIntsimbi emile okwe-Cibizwa ngokuba yi-ASTM A36. Lo mgangatho ugubungela ubume bobume bekhabhoni yentsimbi esemgangathweni ukuze isetyenziswe kwi-riveted, ibhoti okanye ulwakhiwo oludityanisiweyo lweebhulorho kunye nezakhiwo kunye neenjongo zolwakhiwo jikelele. Lo mgangatho uchaza iimfuno zokubunjwa, iimpawu zomatshini kunye nezinye iimpawu ezibalulekileyo ze-carbon steel C-sections.
Enye yeemfuno eziphambili zomgangatho we-ASTM A36 weIntsimbi ye-C-channelkukubunjwa kweekhemikhali zentsimbi esetyenziswa kwimveliso yayo. Umgangatho ufuna insimbi esetyenziselwa i-C-sections ukuba iqulethe amanqanaba athile ekhabhoni, i-manganese, i-phosphorus, isulfure kunye nobhedu. Ezi mfuno ziqinisekisa ukuba insimbi esetyenziswe kwi-C-channel ineempawu eziyimfuneko zokubonelela amandla kunye nokuqina okufunekayo kwizicelo zesakhiwo.
Ukongeza kwimichiza yeekhemikhali, umgangatho we-ASTM A36 uphinde uchaze iimpawu zemishini yentsimbi esetyenziswe kwi-C-section steel. Oku kubandakanya iimfuno zamandla esivuno, amandla okuqina kunye nokwandiswa kwentsimbi. Ezi zakhiwo zibalulekile ukuqinisekisa ukuba i-C-channel yensimbi inamandla ayimfuneko kunye ne-ductility yokumelana nemithwalo kunye noxinzelelo olufunyenwe kwizicelo zokwakha.
Umgangatho we-ASTM A36 uquka ukunyamezela komlinganiselo kunye nokuthe tye kunye neemfuno zokugoba kwintsimbi yecandelo le-C. Ezi nkcukacha ziqinisekisa ukuba amacandelo e-C avelisiweyo kulo mgangatho ahlangabezana neemfuneko zobungakanani kunye neemilo ezifunekayo ekusetyenzisweni kwazo kwiiprojekthi zokwakha.
Ngokubanzi, umgangatho we-ASTM A36 wensimbi ene-C unika isethi ebanzi yeemfuno zomgangatho kunye nokusebenza kwezi zintsimbi. Ngokuthobela lo mgangatho, abavelisi banokuqinisekisa ukuba amacandelo e-C abawavelisayo ahlangabezana neenkcukacha ezifunekayo kwizicelo zokwakha.
Isishwankathelo, umgangatho we-ASTM weIntsimbi ye-C-channel, eyaziwa ngokuba yi-ASTM A36, ichaza iimfuno zokwakheka kweekhemikhali, iipropathi zoomatshini, kunye nokunyamezelwa komda kwezi ntsimbi. Ngokuhlangabezana nezi mfuno, abavelisi banokuvelisa amacandelo e-C aphezulu ahlangabezana nemigangatho efunekayo kwizicelo ezahlukeneyo zokwakha. Ingaba iibhulorho, oomatshini boshishino okanye izakhiwo, ukubambelela kwimigangatho yentsimbi ye-ASTM C-candelo iqinisekisa ukhuseleko kunye nokuthembeka kwentsimbi esetyenzisiweyo.
