Alloy A320 L7 L7M lub tshuab ntxhua khaub ncaws kheev siv rau li cas nrog cov flanges fittings thiab cov hlab ntsha siab
SA 182 lub qhov soitter weld flanges tau koom nrog cov yeeb nkab rau hauv lub qhov (socket) mus rau lub qhov ntev thiab thov kom puv Weld ncig sab saum toj. Qhov no tso cai rau cov dej zoo dua lossis roj sab hauv cov yeeb nkab thiab cov qhov du.
Lub ASTM A320 gr l7 yog cov khoom siv tshwj xeeb rau cov fasteners, bolts, thiab txiv ntoo. Lawv tau npaj rau kev siv hauv cov ntawv thov kub siab ntau. Alloys uas tau muab rau kom muaj qhov kub tsawg yuav tsum tau tiv thaiv kev nthuav dav lossis kev sib txuas nrog kev hloov pauv ntawm qhov kub ntawm lub ambiance. Yuav tsum muaj chav rau lub alloy kom tso cai rau ob qho kev nthuav dav lossis kev sib txuam nyob ntawm cov cua sov nyob hauv ib puag ncig. ASTM A320 WASTER tau npaj rau qhov kev pab tsawg-down -150¡Ã f thiab muaj qhov tsawg kawg nkaus tsub nqi ntawm 20-ft-lbf ntawm qhov kub no. Lub AVTM A320 qib l7 bolts muaj nyob rau hauv cov kev kawm sib txawv thiab txhua tus muaj ntau yam kev ntxhov siab tawg lossis lub zog tensile.
