Kwiminyaka yakutshanje, kuye kwakho utshintsho olukhulu kwindawo yokuqonda i-barbon yentsimbi ye-barbon steel kunye nokuxhathisa kwabo ekubambeni uxinzelelo. Olu tshintsho luye lwalunyanzela ugxininiso oluhlaziyiweyo kumgangatho kunye nemigangatho yemibhobho yentsimbi, ngakumbi ezo zenziwa kwi-ASTM (uMbutho waseMelika uVavanya kunye nezixhobo). Umbhobho wentsimbi ye-carbon kudala wamkelwe okwethutyana kunye nokuthembeka, kunye nokuqinisekiswa komgangatho wamazwe aphesheya kumazwe aphesheya kuyakhanya isikhundla sayo njengabalingane bemveliso.
Ngokwesiko, izabelo ezithile ze-carbon ze-carbon ziye zaqwalaselwa ngokunganyangekiyo kuxinzelelo lokungakhathali, zibangele ukuba zifundwe kwizicelo ezahlukeneyo zophuhliso. Nangona kunjalo, ukuphuculwa kwakutsha nje kubonisa ukuba ezinye zezi zalo zinokubangelwa kuko olu hlobo losulelo. Ukufunyanwa kwabangela inkxalabo kwishishini kwaye kugxininise ukubaluleka kwamanyathelo olawulo esemgangathweni kwimveliso yombhobho wentsimbi.
Ukuphendula kwezi zinto zixhalabisayo,I-ASTM Carbon yentsimbiAbavelisi bathathe amanyathelo asebenzayo okuqinisekisa ukuba lolona nqanaba luphezulu kunye nenqanaba lokusebenza. Oku kuzinikela kubugqwetha ekupheliseni ukuqinisekiswa komgangatho wamazwe aphesheya, ukubonisa ukuba ityhubhu yensimbi ihlangana neemfuno ezingqongqo ezenziwe ngemigangatho yomgangatho wehlabathi. Le mpumelelo ayibonisi kuphela imibhobho yabavelisi beentsimbi kuphela ekugcineni amanqanaba aphezulu asemgangathweni, kodwa ikwaseka imibhobho yentsimbi ye-ASTM njengophawu lweshishini lokuthembeka kunye nokuqina.
Ukuqinisekiswa komgangatho wamazwe aphesheya kwemibhobho ye-MS yensimbi kubaluleke kakhulu kumashishini ahlukeneyo axhomekeke kwimibhobho esemgangathweni esemgangathweni, kubandakanya nolwakhiwo, uphuhliso lweziseko zophuhliso kunye nemveliso yemveliso. Ngokudibana kunye nokudlula kwimigangatho esemgangathweni yamanye amazwe, umbhobho wentsimbi ye-ASTM ubonelela ngeenjineli, iikontraki kunye nabaphathi beeprojekthi kunye nesiqinisekiso sokuba izibonelelo zabo zixhaswe zizixhobo zazo eziqinisekileyo nezinokuthenjwa.
Ukongeza, ukufunyanwa kwesiqinisekiso semgangatho sehlabathi siphakamile imeko yemibhobho ye-ASTM kwi-benchmarks. Njengobubi, umbhobho we-ASTM ibeka imigangatho yokugqwesa kwabanye abavelisi ukuba balandele, ukuqhuba luphuculo olusemgangathweni wentsimbi kunye nokusebenza kuwo wonke umzi mveliso. Oku akuvumelani kuphela abasebenzisi bokuphela ukuze bakhethe ngokuzithembaImibhobho yentsimbi ye-weldiedKwiiprojekthi zabo, kodwa kukhusela ukhuphiswano olusempilweni kunye nezinto ezintsha kwishishini lokwenza intsimbi.
I-ASTM yentsimbi yombhobho yokufumana isiqinisekiso semgangathweni sehlabathi yiTestamente yokuzibophelela kweshishini ekuphuculeni okuqhubekayo kunye nokubambelela kwimigangatho ephezulu kakhulu. Ibalaselisa ukubaluleka kokuhambela phambili kwinkqubela phambili yetekhnoloji kunye nokuhlakulela ukuqonda kweepropathi ezibonakalayo ukuqinisekisa ukuba imibhobho yentsimbi ihlala iphambili ekunyanisekeni nasekusebenzeni.
Isishwankathelo,umbhobho ojikelezileyo wensimbi'sUkufezekiswa kokuqinisekiswa komgangatho wamazwe aphesheya kuphawula ishishini elibalulekileyo kwishishini lentsimbi. Ayisisombululeli kuphela imiceli mngeni ebonakalayo enxulumene noxinzelelo lwe-corrosion kodwa ikwasenza umbhobho wentsimbi
Umgangatho wecandelo lomgangatho womgangatho kunye nokuthembeka. Njengoko umbhobho wentsimbi oqingqiweyo kunye nokuSebenza okuphezulu uyaqhubeka nokukhula, i-ASTM ye-Astm yentsimbi iqinile iqinisa isikhundla sayo njengokhetho oluxinzelelweyo kunye nolokuqala kuluhlu olubanzi lwezicelo
