Ekwakheni nasekwakheni, ukusetshenziswa kwensimbi yesiteshi (evame ukubizwa ngensimbi ye-C-Section) kuvame kakhulu. Lezi ziteshi zenziwa ngensimbi futhi zibunjiwe njenge-C, yingakho igama. Zivame ukusetshenziswa embonini yezokwakha futhi zinokusetshenziswa okuhlukahlukene. Ukuqinisekisa ukuthi ikhwalithi kanye nokucaciswa kwensimbi ye-C-Section ye-C-SECT, umphakathi waseMelika wokuhlola nezinto zokwakha (i-ASTM) uthuthukisa amazinga wale mikhiqizo.
Isilinganiso se-ASTM yeInsimbi eyenziwe nge-Cibizwa nge-ASTM A36. Leli jwayelekile lihlanganisa ukwakheka kwekhwalithi ye-carbon yensimbi ye-carbon ukuze isetshenziswe ekwakhiweni kwamabhuloho kanye noma kwe-welded yamabhuloho nezakhiwo kanye nezinhloso ezijwayelekile zezakhiwo. Leli Zinga licacisa izidingo zokwakheka, izakhiwo zemishini nezinye izici ezibalulekile ze-C-Steel COMET C-SCES.
Enye yezidingo ezibalulekile ze-ASTM A36 ejwayelekile yeInsimbi ye-C-Channelukwakheka kwamakhemikhali kwensimbi esetshenziselwa ukukhiqizwa kwayo. I-Standard idinga insimbi esetshenziselwa izigaba ze-C ukuze iqukethe amazinga athile ekhabhoni, i-manganese, phosphorus, isibabule nethusi. Lezi zidingo ziqinisekisa ukuthi insimbi esetshenziswe ku-C-Channel inezakhiwo ezidingekayo zokuhlinzeka ngamandla nokuqina okudingekayo kwizicelo zesakhiwo.
Ngaphezu kokwakheka kwamakhemikhali, i-ASTM A36 ejwayelekile ibuye icacisa izakhiwo zemishini zensimbi esetshenziswa kwinsimbi ye-C-Section. Lokhu kufaka izidingo zamandla okuvutha, amandla ashubile kanye nokugcwala kwensimbi. Lezi zakhiwo zibalulekile ukuqinisekisa ukuthi i-C-Channel Steel inamandla adingekayo kanye nekhompiyutha ekumelaneni nemithwalo nezingcindezi ezinolwazi ezisetshenzisweni zokwakha.
I-ASTM A36 Standard ibuye ihlanganise ukubekezelelana okubucayi kanye nokuqonda kanye nezidingo ze-curvature zensimbi ye-C-Section. Lokhu kucaciswa kuqinisekisa ukuthi izingxenye ze-C ezikhiqizwa kuleli Zinga zihlangabezana nezidingo zosayizi kanye nezidingo zokwakheka ezidingekayo ekusetshenzisweni kwazo okuhlosiwe.
Sekukonke, i-ASTM A36 ejwayelekile ye-C-Shape Ensimbi inikezela ngesethi ephelele yezidingo zekhwalithi nokusebenza kwalezi zinsimbi. Ngokunamathela kuleli Zinga, abakhiqizi bangaqinisekisa ukuthi izingxenye ze-C zikhiqiza zihlangabezana nokucaciswa okudingekayo kwezicelo zokwakha.
Ngokufingqa, okujwayelekile kwe-ASTM yeInsimbi ye-C-Channel, eyaziwa ngokuthi i-ASTM A36, icacisa izidingo zokwakheka kwamakhemikhali, izakhiwo zemishini, nokubekezelelwa okubucayi kwalezi zinsimbi. Ngokuhlangabezana nalezi zidingo, abakhiqizi bangakhiqiza izingxenye zekhwalithi ephezulu ye-C ezihlangabezana nezindinganiso ezidingekayo ezinhlobonhlobo zokwakha. Noma ngabe kumabhuloho, imishini yezimboni noma izakhiwo, ukunamathela kumazinga ensimbi we-ASTM C-Sec Secture kuqinisekisa ukuphepha nokwethenjwa kwensimbi esetshenzisiwe.
