EN 10216 series ntawm cov qauv: EU cov qauv rau boilers, cov raj pa luam yeeb thiab cov raj superheater

Nyob rau xyoo tas los no, nrog rau kev nce qib ntawm kev lag luam, qhov kev thov rau cov kav hlau zoo tau txuas ntxiv nce ntxiv, tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm boilers, cov kav dej haus luam yeeb, cov kav dej superheater thiab cov kav dej cua preheater. Txhawm rau kom ntseeg tau tias muaj kev nyab xeeb, ruaj khov thiab kev ua tau zoo ntawm cov khoom no, EU tau tsim cov qauv EN 10216 los qhia meej txog cov kev cai thiab kev siv cov kav hlau. Tsab xov xwm no yuav tsom mus rau ob qho qauv tseem ceeb ntawm EU, EN 10216-1 thiab EN 10216-2, tsom mus rau lawv daim ntawv thov, cov qib kav hlau tseem ceeb thiab kev ceev faj thaum siv lawv.

Txuj kev txhais: EN 10216-1 thiab EN 10216-2

EN 10216-1 thiab EN 10216-2 yog cov qauv EU rau kev tsim cov yeeb nkab hlau thiab cov kev cai zoo, tshwj xeeb rau ntau hom yeeb nkab hlau thiab lawv cov xwm txheej siv. EN 10216-1 feem ntau cuam tshuam txog cov kev cai tsim khoom ntawm cov yeeb nkab hlau tsis muaj seamless, tshwj xeeb tshaj yog rau cov ntawv thov xws li cov boilers siab thiab cov yeeb nkab hloov cua sov uas raug rau qhov kub thiab txias siab. EN 10216-2 tsom mus rau cov yeeb nkab hlau alloy tshwj xeeb, xws li cov uas siv dav hauv kev lag luam tshuaj lom neeg thiab fais fab. Cov qauv no qhia txog cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, kev kam rau siab thiab cov khoom tshuaj xyuas tsim nyog ntawm cov yeeb nkab hlau kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov yeeb nkab hlau tsim tawm hauv cov chaw ib puag ncig hnyav xws li kub thiab siab.

Cov kev siv tseem ceeb

Cov kav hlau uas tsim tawm raws li EN 10216 series cov qauv siv dav hauv cov kav dej boiler, cov kav dej haus luam yeeb, cov kav dej kub superheater, cov kav dej ua ntej cua sov thiab lwm yam teb. Cov kav hlau no feem ntau yog siv los tiv taus qhov kub thiab txias, cov pa roj corrosive thiab cov pa dej siab ua haujlwm. Yog li ntawd, lawv yuav tsum muaj lub zog siab, tiv taus corrosion zoo heev thiab thermal conductivity zoo.

Hauv cov khoom siv boiler, EN 10216 series steel kav dej yog siv rau cov kav dej boiler thiab cov kav dej haus luam yeeb kom coj cua sov thiab tso cov pa tawm. Cov kav dej superheater thiab cov kav dej ua ntej cua sov kuj yog cov chaw siv tseem ceeb ntawm cov kav dej hlau no. Lawv lub luag haujlwm yog los txhim kho kev ua haujlwm thermal ntawm cov boilers thiab txo kev siv hluav taws xob.

Cov qib yeeb nkab hlau feem ntau

Hauv EN 10216 series ntawm cov qauv, cov yeeb nkab hlau feem ntau suav nrog:P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10, thiab lwm yamCov yeeb nkab hlau no muaj cov tshuaj sib txawv thiab cov khoom siv lub cev thiab tsim nyog rau ntau qhov chaw ua haujlwm sib txawv. Piv txwv li, P195GH thiab P235GH cov yeeb nkab hlau feem ntau siv rau hauv cov khoom siv boiler, thaum 13CrMo4-5 thiab 10CrMo9-10 feem ntau yog siv rau hauv cov khoom siv tshuaj lom neeg thiab qhov kub thiab txias thiab qhov chaw siab.

Cov kev ceev faj rau kev siv

Txawm hais tias cov kav hlau EN 10216 series muaj kev ua tau zoo heev, qee qhov kev ceev faj yuav tsum tau ua thaum siv lawv. Ua ntej, cov neeg siv yuav tsum xaiv cov kav hlau qib tsim nyog raws li qhov chaw siv tshwj xeeb kom ntseeg tau tias kev ua haujlwm zoo ntawm lub raj xa dej. Qhov thib ob, cov kav hlau yuav tsum tau kuaj xyuas tsis tu ncua thaum siv, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias thiab qhov siab, thiab yuav tsum tau them sai sai rau seb cov kav hlau puas muaj xeb, tawg lossis lwm yam kev puas tsuaj. Thaum kawg, txhawm rau kom ntev lub neej kev pabcuam ntawm cov kav hlau, kev ntxuav thiab kev saib xyuas tsis tu ncua yuav tsum tsis txhob raug tsis quav ntsej.

Cov qauv EN 10216-1 thiab EN 10216-2 muab cov khoom yeeb nkab hlau zoo rau kev tsim khoom hauv kev lag luam, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov khoom siv tseem ceeb xws li boilers, cov yeeb nkab pa luam yeeb, cov raj superheater, thiab lwm yam. Los ntawm kev ua raws li cov qauv no, kev ua haujlwm zoo ntawm cov khoom siv tuaj yeem ua kom siab tshaj plaws thiab kev ua haujlwm tas mus li thiab ruaj khov ntawm kev tsim khoom hauv kev lag luam tuaj yeem ua kom ntseeg tau.
