Daim ntawv thov

Nws yog tsuas yog siv los ua cov pa roj carbon zoo steel, alloy steel qauv thiab stainless hlau kub-resistant steel seamless steel kav rau kev kub siab thiab siab dua chav boiler kav.

Feem ntau yog siv rau kev kub siab thiab kub kev pab cuam ntawm boiler (Superheater raj, reheater raj, cua qhia raj, lub ntsiab chav tub raj rau siab thiab ultra siab siab boilers). Nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, lub raj yuav oxidize thiab corrode. Nws yuav tsum tau hais tias cov yeeb nkab steel muaj cov kav ntev, siab tiv thaiv oxidation thiab corrosion, thiab cov qauv zoo.

Ntev:

Qhov ntev ntev ntawm cov kav hlau yog 4 000 mm ~ 12 000 mm. Tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom, thiab sau rau hauv daim ntawv cog lus, nws tuaj yeem xa cov kav hlau steel nrog qhov ntev ntau dua 12 000 mm lossis luv dua kuv 000 mm tab sis tsis luv dua 3 000 mm; luv luv Cov kav hlau steel tsawg dua 4,000 hli tab sis tsis pub tsawg dua 3,000 hli yuav tsum tsis pub tshaj 5% ntawm tag nrho cov kav hlau xa khoom.

Delivery luj:
Thaum cov yeeb nkab steel xa tawm raws li qhov nominal txheej kab thiab nominal phab ntsa thickness los yog lub nominal puab txoj kab uas hla thiab nominal phab ntsa thickness, cov yeeb nkab steel yog xa raws li qhov tseeb qhov hnyav. Nws kuj tuaj yeem raug xa tawm raws li qhov hnyav theoretical.
Thaum cov yeeb nkab steel xa tawm raws li qhov nominal txheej kab thiab qhov tsawg kawg nkaus phab ntsa thickness, cov yeeb nkab steel yog xa raws li qhov tseeb qhov hnyav; cov khoom thiab cov neeg thov kev sib tham. Thiab nws yog qhia nyob rau hauv daim ntawv cog lus. Cov yeeb nkab steel kuj tuaj yeem xa tawm raws li qhov ntsuas qhov hnyav.

Qhov hnyav kam rau ua:
Raws li cov kev xav tau ntawm tus neeg yuav khoom, tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom, thiab hauv daim ntawv cog lus, qhov sib txawv ntawm qhov hnyav tiag tiag thiab qhov ntsuas theoretical ntawm tus xa khoom steel yeeb nkab yuav tsum ua raws li cov hauv qab no:
a) Ib leeg steel yeeb nkab: ± 10%;
b) Txhua batch ntawm steel kav nrog qhov tsawg kawg nkaus ntawm 10 t: ± 7.5%.

Kev Xeem Xeem

Hydraustatic Test:

Cov yeeb nkab steel yuav tsum tau sim hydraulically ib los ntawm ib qho. Qhov ntsuas siab tshaj plaws yog 20 MPa. Nyob rau hauv qhov kev sim siab, lub sij hawm stabilization yuav tsum tsis pub tsawg tshaj 10 s, thiab cov yeeb nkab steel yuav tsum tsis txhob xau.

Tom qab tus neeg siv pom zoo, qhov kev ntsuam xyuas hydraulic tuaj yeem hloov tau los ntawm kev ntsuas tam sim no los yog kev ntsuam xyuas qhov sib nqus flux.

Nondestructive Test:

Cov kav dej uas xav tau kev tshuaj xyuas ntau dua yuav tsum tau kuaj xyuas ultrasonically ib los ntawm ib qho. Tom qab kev sib tham yuav tsum tau tso cai los ntawm tog thiab tau teev nyob rau hauv daim ntawv cog lus, lwm yam uas tsis yog-tshuaj ntsuam xyuas yuav muab ntxiv.

Flattening Test:

Cov raj uas muaj ib txoj kab uas hla sab nraud ntau dua 22 hli yuav tsum raug kuaj kom haum. Tsis pom delamination, dawb me ntsis, los yog impurities yuav tsum tshwm sim thaum lub sij hawm tag nrho kev sim.

Flaring Test:

Raws li qhov yuav tsum tau muaj ntawm tus neeg yuav khoom thiab tau teev nyob rau hauv daim ntawv cog lus, cov yeeb nkab steel nrog lub taub sab nraud ≤76mm thiab phab ntsa thickness ≤8mm tuaj yeem ua tiav kev sim ntsuas. Qhov kev sim tau ua nyob rau hauv chav tsev kub nrog ib tug taper ntawm 60 °. Tom qab qhov flaring, qhov flaring tus nqi ntawm lub sab nraud yuav tsum tau raws li qhov yuav tsum tau ntawm cov lus hauv qab no, thiab cov khoom siv kuaj yuav tsum tsis txhob pom cov kab nrib pleb lossis rips.
