SA192 seamless steel yeeb nkab yog cov khoom siv siab- zoo steel yeeb nkab khoom siv dav hauv boilers, superheaters, heat exchangers, thiab lwm yam siab - kub thiab siab - siab ib puag ncig. Nws zoo heev -kub tsis kam, zoo mechanical zog, thiab ruaj khov tshuaj ua rau nws ib tug indispensable tivthaiv nyob rau hauv industries xws li lub hwj chim, petrochemicals, thiab lub zog.
Kev Xav Tau
- Chemical Composition: nruj me ntsis tswj cov ntsiab lus ntawm cov ntsiab lus xws li carbon (0.06%-0.18%), silicon (Less tshaj los yog sib npaug rau 0.25%), thiab manganese (0.27%-0.63%), thaum txwv cov impurity cov ntsiab lus ntawm phosphorus (tsawg tshaj los yog sib npaug rau 0.035%) thiab sib npaug rau 0.035% sulfur.
- 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 li 35%, Brinell hardness Tsawg dua los yog sib npaug rau 137HB, Rockwell hardness Tsawg dua los yog sib npaug rau 77HRB, kom ntseeg tau cov khoom siv zoo heev.
- Dimensional Tolerances: Sab nraud txoj kab uas hla ntawm qhov kam rau ua yog +0.4mm rau -1.2mm (kub-rolled tube) thiab +0.10mm txog +0.38mm (txias-draw tube); phab ntsa thickness kam rau ua ntau yam yog +20% mus rau 0 (txias-kho raj) thiab +28% mus rau 0 (kub-khoov raj), ua tau raws li qhov yuav tsum tau ua ntawm high-precision manufacturing.
Cov yam ntxwv ua haujlwm
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.
