I-ASTM A213 T9, ekwaziwa ngokuba yi-ASME SA213 T9, ayisebenzi kakhuluityhubhu yentsimbi engenamthungoisetyenziselwa iibhoyila, ii-superheater, kunye nee-heat exchangers.
I-T9 yi-alloy ye-chromium-molybdenum equlethe i-8.00–10.00% ye-chromium kunye ne-0.90–1.10% ye-molybdenum. Inamandla okutsalwa aphantsi angama-415 MPa kunye namandla okuvelisa aphantsi angama-205 MPa. Ngamandla ayo aphezulu obushushu, ukumelana nokuxinana, kunye nokumelana nokuqhekeka, i-T9 isebenza ngokuthembekileyo phantsi kweemeko zokusebenza zobushushu obuphezulu kunye noxinzelelo oluphezulu.
Njengomthengisi weepayipi zentsimbi ye-alloy yobungcali kunye nomthengisi ngobuninzi eTshayina,Intsimbi yeBotopinokubonelela ngokukhawuleza ngoluhlu olubanzi lweepayipi zentsimbi ze-T9 kwiiprojekthi zakho, ngomgangatho othembekileyo kunye namaxabiso akhuphisanayo.
Imveliso enikezelwe kwi-ASTM A213 kufuneka ihambelane neemfuno zeNkcazelo ye-ASTM A1016, kuquka naziphi na iimfuno ezongezelelweyo eziboniswe kwi-odolo yokuthenga.
I-ASTM A1016: Ingcaciso esemgangathweni yeemfuno ezibanzi zeFerritic Alloy Steel, iAustenitic Alloy Steel, kunye neeTubes zeStainless Steel
Umenzi kunye neMeko
Imibhobho yentsimbi ye-ASTM A213 T9 mayiyenziwe ngenkqubo engenamthungo kwaye mayigqitywe ngokushisa okanye ngokubandayo, njengoko kuchaziwe.
Unyango lobushushu
Imibhobho yentsimbi ye-T9 kufuneka ifudunyezwe ukuze ifudunyezwe ngokweendlela ezilandelayo, kwaye unyango lobushushu kufuneka lwenziwe ngokwahlukeneyo kwaye ukongeza ekufudunyezweni ukuze kwenziwe ubushushu.
