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

Nyob rau hauv xyoo tas los no, nrog rau kev nce qib ntawm kev lag luam, qhov kev thov rau cov kav hlau zoo nkauj tau txuas ntxiv mus ntxiv, tshwj xeeb tshaj yog nyob rau hauv kev lag luam ntawm boilers, pa luam yeeb raj, superheater raj thiab cua preheater raj. Txhawm rau kom muaj kev nyab xeeb, ua haujlwm ntev thiab ua haujlwm ntawm cov khoom no, EU tau tsim cov qauv EN 10216 series los qhia meej txog cov kev cai thiab kev siv cov kav hlau. Kab lus no yuav tsom mus rau ob qho tseem ceeb EU qauv, EN 10216-1 thiab EN 10216-2, tsom rau lawv daim ntawv thov, cov qib steel yeeb nkab tseem ceeb thiab ceev faj thaum siv lawv.

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

EN 10216-1 thiab EN 10216-2 yog EU cov qauv rau kev tsim cov yeeb nkab steel thiab cov kev xav tau zoo, tshwj xeeb tshaj yog rau ntau hom steel kav thiab lawv cov xwm txheej siv. TS EN 10216-1 feem ntau suav nrog kev tsim cov kav dej seamless steel, tshwj xeeb tshaj yog rau cov ntawv thov xws li kev kub siab boilers thiab cov kav dej kub hloov mus rau qhov kub thiab txias. TS EN 10216-2 tsom rau cov yeeb nkab steel tshwj xeeb, xws li cov dav siv hauv kev lag luam tshuaj thiab hluav taws xob. Cov qauv no qhia txog cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev ntev thiab cov khoom siv tshuaj xyuas tsim nyog ntawm cov kav hlau steel kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov kav hlau tsim hauv qhov chaw hnyav xws li qhov kub thiab txias.

Kev siv tseem ceeb

Cov kav hlau ua tau raws li EN 10216 series qauv yog dav siv hauv cov kav dej boiler, cov kav dej haus luam yeeb, cov kav dej superheater, cov kav dej ua cua sov thiab lwm yam. Cov kav hlau no feem ntau yog siv los tiv thaiv qhov kub thiab txias, corrosive gases thiab high-pressure chav ua haujlwm ib puag ncig. Yog li ntawd, lawv yuav tsum muaj lub zog siab, zoo heev corrosion kuj thiab zoo thermal conductivity.

Hauv cov khoom siv boiler, EN 10216 series steel kav yog siv rau cov kav dej boiler thiab cov kav dej haus luam yeeb los ua kom sov thiab tso pa tawm. Superheater kav thiab cua preheating kav kuj tseem ceeb heev daim ntawv thov ntawm no series ntawm steel kav. Lawv lub luag haujlwm yog txhawm rau txhim kho cov thermal efficiency ntawm boilers thiab txo lub zog noj.

Common steel yeeb nkab qib

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

Kev ceev faj rau kev siv

Txawm hais tias EN 10216 series steel kav muaj kev ua tau zoo, qee qhov kev ceev faj tseem yuav tsum tau ua thaum siv lawv. Ua ntej, cov neeg siv yuav tsum xaiv cov qib steel yeeb nkab uas tsim nyog raws li cov ntawv thov ib puag ncig kom ntseeg tau tias kev ua haujlwm nyab xeeb ntawm cov kav dej. Qhov thib ob, cov yeeb nkab steel yuav tsum tau kuaj xyuas tsis tu ncua thaum siv, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias ib puag ncig, thiab yuav tsum tau saib xyuas seb cov yeeb nkab puas muaj corrosion, tawg lossis lwm yam kev puas tsuaj. Thaum kawg, txhawm rau txhawm rau txuas lub neej kev pabcuam ntawm cov yeeb nkab steel, kev tu thiab tu tsis tu ncua yuav tsum tsis txhob raug ignored.

EN 10216-1 thiab EN 10216-2 series ntawm cov qauv muab cov khoom lag luam zoo steel yeeb nkab rau kev tsim khoom, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov cuab yeej tseem ceeb xws li boilers, cov kav dej haus luam yeeb, cov raj superheater, thiab lwm yam.
