UNS K11597 - ASME SA-335 / ASTM A335 P11 yog ib qho hlau tsis muaj qhov txuas (seamless) 1.25% Chromium - 0.5% Molybdenum (1.25Cr-0.5Mo) ferritic alloy steel pipe, tsim rau kev siv tas li hauv boilers, superheaters, pressure vessels, thiab high-temperature steam piping. Lub npe hu ua chrome-moly lossis Cr-Mo pipe, P11 muab kev tiv thaiv creep thiab oxidation zoo tshaj 400°C, ua rau nws yog cov khoom xaiv tus qauv thoob plaws hauv kev tsim hluav taws xob, cov chaw petrochemical, cov chaw ua roj, thiab cov tshuab cua sov hauv ntiaj teb.
Chromium nyob rau hauv 1–1.5% ntau tsim ib txheej chromium oxide ruaj khov uas tiv thaiv cov raj tiv thaiv oxidation thiab scaling ntawm qhov kub siab. Molybdenum ntawm 0.44–0.65% ntxiv dag zog rau ferrite matrix thiab ua kom qeeb dislocation creep nyob rau hauv kev thauj khoom ntev ntawm qhov kub siab. Ua ke, ob lub alloying elements no muab P11 nws qhov kev sib txuas ntawm kev tiv thaiv cua sov thiab kev ruaj khov mus ntev.
Cov lus hauv qab no qhia cov khoom sib ze tshaj plaws rau ASTM A335 P11 thoob plaws cov qauv thoob ntiaj teb. Cov qauv no zoo ib yam thiab feem ntau raug lees txais ua cov khoom hloov hauv cov haujlwm thoob ntiaj teb uas ib qho qauv raug teev tseg thiab lwm qhov tau txais.
ASTM A335 hais kom P11 pipe xa tuaj rau hauv normalized thiab tempered condition (full lossis isothermal annealing kuj tso cai).
Cov ferrite-carbide microstructure ua rau muaj creep strength, ductility, thiab toughness uas xav tau rau kev ua haujlwm kub siab ntev.
Cov lus hauv qab no qhia ib feem ntawm peb cov khoom tam sim no. Hu rau peb rau kev hloov tshiab, ntau qhov ntau thiab tsawg, lossis cov qauv tsis yog tus qauv.
Qhov Ntev: 5800mm / 6000mm / 6096mm / 7315mm / 11800mm / 12000mm (custom muaj)
Qhov ntev siab tshaj: 16000mm; U-bending kuj muaj.
Cim: Cov lus saum toj no qhia ib feem ntawm peb cov khoom tam sim no. Rau ntau qhov ntau thiab tsawg, ntau npaum li cas, lossis cov qauv tsis muaj, thov hu rau peb.
