Daim ntawv thov
Siab Vessels & Boilers: Zoo tagnrho rau tsim cov hlab ntsha thiab boilers hauv roj av, tshuaj, thiab hluav taws xob sectors.
Tsawg- Kev Pabcuam Kub: Nws cov ntsiab lus nickel siab (ib puag ncig 2.25% rau Qib B) muab kev cuam tshuam zoo heev hauv qhov chaw txias, ua rau nws tsim nyog rau cov ntawv thov cryogenic xws li cov roj liquefied cia.
Roj & Roj: Siv nyob rau hauv cov khoom siv roj thiab roj ua thiab thauj.
Kev Lag Luam Tshuaj: Siv rau cov tso tsheb hlau luam thiab cov khoom siv hauv cov nroj tsuag tshuaj.
Huab cua sib cais & Cryogenic ua: dav siv nyob rau hauv huab cua sib cais units (ASUs) thiab cov khoom siv rau kev sib cais cryogenic.
Thov kom muaj kev tshaj lij rau SA 203 Qib B los ntawm GNEE Steel.
1.Dab tsi yog SA 203 khoom?
SA203/SA203M steel yog ib qho zoo heev steel siv nyob rau hauv fabrication ntawm tsawg-kub vuam siab hlab ntsha. Peb txhawb hom hlau no ntawm nws tus nqi sib tw tshaj plaws. Peb SA203E siv lead ua hauv nws qhov qis -kub ductility khoom nyob rau hauv thoob ntiaj teb zoo, nrog ib tug max thickness ntawm 100mm.
2.Dab tsi yog qib B steel?
Qib B steel, lossis 9260 steel, yog qib siab - silicon alloy nrog kwv yees li 0.60% carbon, ua rau nws lub caij nplooj ntoos hlav hlau.
3. Stainless hlau B txhais li cas?
Cov yam ntxwv B stainless hlau yog qhov hloov pauv ntawm 304 thiab kuj tau muab tshem tawm. Qhov sib txawv heev, txawm li cas los xij, hom 304 mob B yog qhov muaj zog dua thiab tsawg dua. Qhov no yog ua tiav los ntawm kev ua haujlwm txias.
