SA192 boiler raj feem ntau yog siv nyob rau hauv siab - siab boilers, nrog rau cov khoom xws li cua sov saum npoo, headers, economizers, superheaters, thiab reheaters. Lawv cov kev ua haujlwm siab feem ntau tsis tshaj 9.8 MPa, thiab lawv qhov kev ua haujlwm kub yog nyob nruab nrab ntawm 450℃thiab 650 degree.
Cov yam ntxwv tseem ceeb
Khoom siv
Cov ntsiab lus carbon 0.06%-0.18%, Manganese 0.27%-0.63%, Phosphorus / Sulfur Tsawg dua lossis sib npaug li 0.035%, txwv tsis pub ntxiv cov ntsiab lus alloying uas tsis tau teev tseg.
Mechanical Properties
Tensile zog Ntau dua los yog sib npaug rau 325MPa, Yield zog Ntau dua los yog sib npaug rau 180MPa, Elongation Ntau dua los yog sib npaug rau 35%, Hardness sab sauv txwv 137HB lossis 77HRB.
Qhov ntev
Sab nraud txoj kab uas hla 12.7-177.8mm, Phab ntsa thickness 2.2-25.4mm, Cold-drawn hlab xav tau ntau dua lossis sib npaug rau 650℃kev kho cua sov.
Nta:
1. Qhov Zoo Tshaj Plaws Siab-Kev Ua Haujlwm Kub: Ua kom ruaj khov tensile lub zog (Ntau dua lossis sib npaug ntawm 325MPa) thiab lub zog tawm los (Ntau dua lossis sib npaug rau 180MPa) txawm tias lub sijhawm ua haujlwm ntev -lub sijhawm ua haujlwm qis dua 540 degree, ua rau nws tshwj xeeb tshaj yog haum rau cov dej- cov phab ntsa txias rau cov nroj tsuag.
2. Cov Txheej Txheem Ua Haujlwm Zoo: Cov khoom tiav ntawm cov raj hlau tau los ntawm kev kos duab txias tuaj yeem ncav cuag Ra Tsawg dua lossis sib npaug ntawm 0.8μm, thiab qhov tseeb qhov tseeb yog tswj tsis pub dhau ± 0.1mm, tso cai siv ncaj qha rau hauv kev sib dhos ntawm cov khoom siv hluav taws xob sib hloov.
3. Kev nyab xeeb thiab kev ntseeg tau: nruj me ntsis ua raws li ASME SA192 cov qauv, yuav tsum tau kuaj hydrostatic (Ntau dua lossis sib npaug ntawm 6.9MPa), eddy tam sim no kuaj, lossis kuaj ultrasonic kom tsis muaj qhov tsis xws luag xws li tawg thiab folds.
