Dab tsi yog 304 / 304L dual muaj ntawv pov thawj stainless hlau yeeb nkab hlau?

304 / 304L Dual Pov Thawj Hlau Yeeb Nkab hais txog cov kav dej thiab cov khoom siv neeg kho mob ntawm astm A312 thiab TPTP4L. Cov kav dej no muab cov xaim hluav taws xob tiv taus thiab lub zog ntawm 304 stainless hlau cov ntsiab lus ntawm 304L, uas txhim kho kev pheej hmoo ntawm kev cuam tshuam ntawm corrosion.

 

Firstly, cia peb pom 304 thiab 304L ua raws rau ASTM A312 specification rau welded thiab seamless tubing, feem ntau, peb muaj kev sib txawv ntawm 304, "L" txhais tau tias tsawg cov ntsiab lus hauv Carbon keeb.

Kev qhia tshwj xeeb

Dab tsi yog "dual ntawv pov thawj" txhais tau tias hauv cov yeeb nkab steel hlau?

"Dual ntawv lees paub" txhais tau tias cov yeeb nkab ua raws li 304 thiab 304L cov qauv. Nws muaj cov ntsiab lus muaj peev xwm (tsawg dua los yog sib npaug rau 0.03%) haum rau kev tsim kho (304L), thaum ob lub zog thiab corrosion tsis kam.

 

Dab tsi yog qhov zoo ntawm kev siv 304 / 304L Ob Cov Ntawv Pov Thawj Hluav Taws Xob?

Weldability:304L cov pa roj carbon ntau tsawg zaus carbide nag lossis daus.

Corrosion Kuj:Qhov zoo tshaj plaws rau cov zaub mov -}}} Cov tshuaj, thiab huab cua raug.

Cov lus nug ua tau zoo:Cov kws ua choj tuaj yeem ua kom zoo rau cov khoom siv rau cov phiaj xwm nce qib.

Kev cai ua raws cai:Ua tau raws li ob qho tib si asme thiab Astm cov qauv rau cov ntawv thov siab.

 

Yog dual ntawv pov thawj 304 / 304L stainless hlau yeeb nkab haum rau vuam?
Yog lawm. Ib qho ntawm cov laj thawj tseem ceeb rau ob daim ntawv pov thawj dua yog muab kev siv weldability. Cov pa roj carbon tsawg nyob rau hauv 304L minimizes rhiab kawg (carbide nag lossis daus ntawm cov ciaj ciam), uas tuaj yeem qee yam ua rauintergranular corrosionTom qab vuam. Dual daim ntawv pov thawj yog dav siv nyob rau hauv Welded cov ntawv thov yam tsis muaj qhov xav tau rau post- Weld kev kho cua sov.

 

Dab tsi cov qauv npog 304 / 304L steel hlau kav hlau?
Ob daim ntawv pov thawj dual feem ntau ua raws li cov qauv hauv qab no:

ASTM A312- Seamless thiab Welded Austenitic Stainless Hlau Kav rau kub thiab kub corrosive kev pab cuam

ASTM A213 / A269- Rau seamless thiab welded tubing siv nyob rau hauv tshav kub hloov lossis condensers

ASME B36.19M- Npog cov hlau stainless yeeb nkab

Cov ntawv pov thawj kuj tseem tuaj yeem suav nrogPed, AD2000, EN10216-5, thiabISO 9001, nyob ntawm cov neeg yuav tsum tau ua.
