Product Description
ASTM A335 P22 alloy yeeb nkab yog dab tsi?
ASTM A335 P22 yog seamless ferritic alloy steel yeeb nkab, tshwj xeeb uas tsim los rau siab - kub thiab siab - kev siv siab. Cov khoom no belongs rau chromium-molybdenum alloy steel series. Los ntawm kev ntxiv chromium thiab molybdenum cov ntsiab lus, nws muaj kev nkag siab zoo heev thiab oxidation kuj nyob rau hauv siab - kub.
P22 Cov yeeb nkab cov ntaub ntawv feem ntau yog xa mus rau hauv lub xeev zoo li qub thiab tempered, nrog cov qauv microstructure thiab ruaj khov txhua yam khoom siv. Cov ntsiab lus chromium ua rau nws tsim cov yeeb yaj kiab tiv thaiv oxide nyob rau hauv qhov siab -kub oxidative cua, yog li ncua lub neej kev pab cuam; lub molybdenum caij pab txhim kho lub creep rupture lub zog ntawm cov khoom ntawm kub kub.
Cov khoom no muaj feem xyuam rau cov kav dej loj, lub taub hau boiler, cov raj superheater ntawm thermal fais fab nroj tsuag, nrog rau lub siab - cov kav dej kub txheej txheem thiab hydrogenation units hauv kev lag luam petrochemical, thiab lwm yam, qhov chaw ua haujlwm yog qhov xav tau heev. P22 muaj kev ua haujlwm zoo heev thiab weldability, thiab yog ib qho kev paub tab thiab siv dav hauv kev kub siab - kub thiab siab - cov kav xa dej.

Cov yam ntxwv ntawm kev tsim khoom
1.Excellent siab -kub creep fracture zog
Ntawm qhov kub siab tshaj 400 degree, P22 pipeline, ua tsaug rau nws cov chromium-molybdenum muaj pes tsawg leeg, tuaj yeem tiv taus creep deformation rau lub sijhawm ntev. Peb tau muab cov raj xa dej rau ntau qhov kev tsim hluav taws xob, thiab cov lus qhia txog kev ua haujlwm tiag tiag qhia tau hais tias lub neej kev pabcuam ntawm P22 pipeline nyob rau hauv siab - qhov kub thiab txias yog qhov ntev dua li cov pa roj carbon zoo tib yam.
2.Excellent antioxidant thiab corrosion-resistant zog
Cov ntsiab lus chromium hauv P22 yog li ntawm 1.90% mus rau 2.60%, ua kom nws tsim cov txheej txheem oxide tuab ntawm qhov kub thiab txias. Nyob rau hauv siab -cov txheej txheem kub ntawm cov roj refineries, tus yam ntxwv no ua rau txo qhov corrosion ntawm cov phab ntsa sab hauv ntawm cov kav dej.
3.Mature welding thiab kev ua tau zoo
Piv nrog rau qee qhov siab -cov ntaub ntawv alloy, ASTM A335 P22 muaj cov txheej txheem vuam paub tab:
- Tsis muaj kev ua kom sov ua ntej thiab tom qab- kev kho cua sov yuav tsum tau ua (tab sis nws raug pom zoo kom ua raws li cov qauv)
- Haum rau ntau txoj kev vuam
- Qhov xav tau sib npaug ntawm hardness thiab toughness tuaj yeem ua tiav los ntawm normalizing ua raws li tempering (N + T).
Los ntawm kev xav ntau lawm, qhov no txo cov kev tsim khoom nyuaj ntawm cov khoom siv kav dej.
4.Stable mechanical zog thoob plaws qhov kub thiab txias
P22 Lub raj xa dej tuaj yeem tswj hwm nws cov khoom siv kho tshuab thoob plaws qhov kub thiab txias ntawm chav tsev kub mus rau qhov kub thiab txias, thiab haum rau:
- Main chav pipeline ntawm lub fais fab nroj tsuag
- Boiler superheater thiab reheater
- Hydrogenation chav tsev ntawm cov roj refinery
- High -kub tshuaj reactor pipeline
