Boiler Seamless Yeeb Nkab

Boiler seamless cov yeeb nkab yog qhov ua tau zoo seamless yeeb tsim tshwj xeeb rau boiler systemment, feem ntau yog rau kev hloov cua sov hauv qhov kub thiab qhov chaw siab. Nws cov tub ntxhais feature yog cov qauv welded-dawb, uas zam kev ua kom muaj peev xwm ua tau zoo ntawm kev nyab xeeb ntawm kev nyab xeeb, siab tsis kam thiab corrosion tsis kam.

• Boiler System: Nws yog siv rau cov khoom tseem ceeb xws li cov kav dej tseem ceeb, superineaters, reseaters thiab cua sov sib pauv hauv chaw nres tsheb fais fab thiab muaj boilers.

• Kev kub siab thiab qhov chaw siab: Nws tuaj yeem tiv thaiv tau ntev li ntawm 400 kev kawm tiav qib siab txog 600 degree thiab lub siab ntawm dhau 30mpa.

• Tshwj Xeeb Tshaj Tawm: Conveying dej, chav dej, high-kub-kub flue roj lossis corrosive media (xws li sulphurur-muaj roj).

• Khoom Siv:

1. Cov Hlau Hlau:ASTM A106 (Kev pab kub siab), A192 (High-siab me-diam rau choj), A210 (nruab nrab thiab kub-kub boiler hlab).
2. Alloy Steel:ASTM A335 (chromium-molybdenum alloy, tiv taus cov high-kub corrosion).
3. Stainless hlau: Siv rau hauv ib puag ncig corrosive loj (xws li lub zog tsim lossis tshuaj siv roj ntsha).

• Cov Qauv Thoob Ntiaj Teb:

1. Tuam Tshoj: GB 5310 "Seamless Cov Hlau Hlawv Rau Siab-Siab Boilers"
2. Tebchaws Asmeskas: ASTM Series A (xws li A106, A192).
3. European Union: EN 10216 (P195 \/ P235 \/ P235 \/ P265, thiab lwm yam)
4. Nyiv: JIS G3461 \/ G3462.

• Welded-pub dawb qauv:

Tshem tawm qhov kev pheej hmoo ntawm weld cracking thiab yoog kom muaj kev kub siab cyclic.

• Kev kub siab thiab kub siab kuj:

Cov khoom undergoes nruj nruj kev kho cua sov (xws li normaling thiab tempering) kom ntseeg tau lub zog ruaj khov ntawm cov kub.

• Corrosion Kuj:

Txhim khu kev txhim kho corrosion tsis kam los ntawm alloy muaj kev tsim qauv (xws li cr, mo) lossis txoj kev kho sab (xws li txhaj tshuaj blasting).

• Precision Qhov ntev:

Nruj nruj (xws li txheej hla dej ± 1%, phab ntsa tuab ± 10%) kom cov kev lis kev sib khi ua tau zoo.

• Cov txheej txheem kub dov:

Hloov cov hlau billets yog rhuab rau 1200 degree, ces perforated thiab tsim rau hauv cov leeg ntxhib los ntawm cov mills.

Nws yog qhov haum rau cov kab uas loj-tuab-walled kav dej (xws li lub coom chav kav dej ntawm lub tog fais fab).

• Cov txheej txheem kos khaub thuas:

Kub-dov lub hlab yog pickled thiab txias-kos kom tau txais high-precision cov leeg (xws li cov leeg siam-lub taub).

• Kev Kho Cua Sov:

Xyaum txhim kho cov qauv grain, thaum tempering tshem tawm kev ntxhov siab sab hauv.

• Tshuaj xyuas:

• Tsis yog kev sim ua tsis zoo: Ultrasonic (UT) thiab EDDY tam sim no (li) nrhiav kom muaj kev cuam tshuam nrog sab hauv.

• Kev Ntsuas Lub Cev thiab Tshuaj: Tensile Kuaj, Kev Kuaj Hardness, Meballographic Kev Ntsuam Xyuas.

Parameter txuam:

• Qhov Kub \/ Siab: Piv txwv li, A106 yog qhov tsim nyog rau tsawg dua lossis sib npaug rau 450 degree, thiab A335 P11 \/ P22 yog qhov tsim nyog rau tsawg dua lossis sib npaug nrog 600 degree.
• Nruab nrab corrosiveness: Hauv cov sulphur-muaj ib puag ncig, cr-m-m alloy lossis austenitic stainless hlau yuav tsum tau xaiv.
• Kev yuav tsum tau muaj tsawg yam nyob sab: Xws li cov uas hla (Od 10-1200 mm), phab ntsa thickness (2-100 mm).

• Kev soj ntsuam tsis tu ncua:

Kev ntsuas ultrasonic tuab (rau kev saib xyuas phab ntsa thickness thinning) thiab endoscopy rau sab hauv corrosion kev soj ntsuam.
Them sai sai rau thermal flocts tawg (tshwj xeeb yog nyob ze welds lossis nyob rau hauv lauj kaub).

• Hloov qauv qauv:

Lub phab ntsa thickness poob tshaj tus qauv tsim muaj nuj nqis los ntawm 20%, lossis oxidation oxidation thiab kev ua yeeb yam loj heev.

• Lub hwj chim nuclear: Cov leeg hloov cua sov rau chav tsim hluav taws xob hauv cov kob nuclear (siv inconel alloy seamless hlab).
• Petrochemical Kev Lag Luam: Hydrogenation Reactors, Kev Kub-Kub Kev Ua Rauv Pipelines.
• Lub Zog Tshiab: Molten ntsev thaum tshav kub hloov cov leeg hauv hnub ci thermal zog ntau zog tiam.

Boiler seamless steel tubes yog cov "cov hlab ntsha" ntawm lub zog boiler. Lawv cov khoom siv weld-dawb thiab cov khoom ua haujlwm siab ua kom muaj kev nyab xeeb rau kev ua haujlwm hnyav heev. Thaum xaiv cov qauv, cov ua haujlwm tsis zoo yuav tsum tau sib phim. Kev saib xyuas tsis tu ncua ncua sijhawm lub neej.
