Ekwakhiweni nasekwakhiweni, ukusetyenziswa kwentsimbi yesiteshi (edla ngokubizwa ngokuba yintsimbi ye-C-section) kuqhelekile kakhulu. Ezi ziteshi zenziwe ngentsimbi kwaye zimile njengo-C, yiyo loo nto zibizwa njalo. Zisetyenziswa kakhulu kushishino lokwakha kwaye zineendlela ezahlukeneyo zokusetyenziswa. Ukuqinisekisa ukuba umgangatho kunye neenkcukacha zentsimbi ye-C-section ziyagcinwa, i-American Society for Testing and Materials (ASTM) iphuhlisa imigangatho yezi mveliso.
Umgangatho we-ASTM weIntsimbi emile okwe-Cibizwa ngokuba yi-ASTM A36. Lo mgangatho ugubungela iimilo zentsimbi yekhabhoni ezisemgangathweni wolwakhiwo ezisetyenziselwa ukwakhiwa kweebhulorho nezakhiwo ezinameva, ezibotshelelweyo okanye ezitshixiweyo kunye neenjongo zesakhiwo ngokubanzi. Lo mgangatho uchaza iimfuno zokwakheka, iimpawu zoomatshini kunye nezinye iimpawu ezibalulekileyo zentsimbi yekhabhoni C-sections.
Enye yeemfuno eziphambili zomgangatho we-ASTM A36Intsimbi ye-C-channelyikhemikhali equlunqwe yintsimbi esetyenziswa kwimveliso yayo. Umgangatho ufuna intsimbi esetyenziselwa ii-C-sections ukuba iqulathe amanqanaba athile ekhabhoni, i-manganese, i-phosphorus, i-sulfur kunye ne-copper. Ezi mfuneko ziqinisekisa ukuba intsimbi esetyenziswa kwi-C-channel ineempawu ezifunekayo zokubonelela ngamandla kunye nokuqina okufunekayo kwizicelo zesakhiwo.
Ukongeza kwimilo yeekhemikhali, umgangatho we-ASTM A36 ukwachaza iipropati zoomatshini zentsimbi esetyenziswa kwintsimbi ye-C-section. Oku kuquka iimfuno zamandla okuvelisa, amandla okutsalwa kunye nokwandiswa kwentsimbi. Ezi mpawu zibalulekile ukuqinisekisa ukuba intsimbi ye-C-channel inamandla kunye nokuguquguquka okufunekayo ukumelana nemithwalo kunye noxinzelelo olufumanekayo kwizicelo zokwakha.
Umgangatho we-ASTM A36 ukwagubungela ukunyamezelana okulinganayo kunye neemfuno zokuthe tye kunye nokugoba kwentsimbi ye-C-section. Ezi nkcukacha ziqinisekisa ukuba ii-C-sections ezenziwe kulo mgangatho ziyahlangabezana neemfuno zobungakanani kunye nemilo ezifunekayo ekusetyenzisweni kwazo kwiiprojekthi zokwakha.
Lilonke, umgangatho we-ASTM A36 wentsimbi enomfanekiso ka-C ubonelela ngeseti epheleleyo yeemfuno zomgangatho kunye nokusebenza kwezi ntsimbi. Ngokulandela lo mgangatho, abavelisi banokuqinisekisa ukuba ii-C-sections abazivelisayo ziyahlangabezana neemfuno ezifunekayo kwizicelo zokwakha.
Ngamafutshane, umgangatho we-ASTM weIntsimbi ye-C-channel, eyaziwa ngokuba yi-ASTM A36, ichaza iimfuno zokwakheka kweekhemikhali, iimpawu zoomatshini, kunye nokunyamezelana kwezi ntsimbi. Ngokuhlangabezana nezi mfuno, abavelisi banokuvelisa ii-C-sections ezikumgangatho ophezulu ezihlangabezana nemigangatho efunekayo kwiintlobo ngeentlobo zezicelo zokwakha. Nokuba ziibhulorho, oomatshini bemizi-mveliso okanye izakhiwo, ukunamathela kwimigangatho yentsimbi ye-ASTM C-section kuqinisekisa ukhuseleko kunye nokuthembeka kwentsimbi esetyenzisiweyo.
