Cov qhab nia xaiv tau
- TP310H muaj cov qib siab ntawm chromium thiab npib tsib xee dua li TP309H, ua rau nws haum rau qhov kub siab heev - qhov kub thiab txias - xws li hydrocarbon refining furnace tubes thiab chav superheaters - txawm tias nws los ntawm tus nqi siab dua.
- Rau siab - siab, siab - chloride daim ntawv thov uas yuav tsum tau superior zog thiab zoo pitting corrosion kuj, 2205 duplex stainless hlau yog ib qho kev xaiv tsim nyog.
- TP347/TP347H yog tus nqi ntau dua- zoo dua TP348 thiab nquag siv hauv kev lag luam petrochemical rau siab -kub, hydrogen- nplua nuj kev pabcuam thiab cov ntawv thov uas yuav tsum tau ua haujlwm rau polythionic acid kev nyuaj siab corrosion cracking.
thaj chaw thov
- Crude Distillation Unit (CDU/VDU): Atmospheric and vacuum tower overhead kab, sab -kos piping, thiab furnace radiant tubes.
- Kua Catalytic Cracking (FCC) & Hydrocracking: Siab -kub catalyst hloov kab, lub ntsiab fractionator kub exchanger raj bundles, thiab reactor hydrocarbon vapor kab.

FAQ
Q: Dhau li ntawm tus qauv 6-meter ntev, koj puas tuaj yeem muab cov kav dej ntev dua kom txo tau cov pob qij txha?
A: A: Yog. Peb muaj peev xwm muab ib leeg, seamless kav ntawm 9 meters, 12 meters, thiab txawm 18 meters, tshwj xeeb tshaj yog haum rau tshav kub exchanger raj bundles thiab txheej txheem piping ntawm cov yeeb nkab racks.
Q: ASTM A312 seamless stainless hlau raj puas tuaj yeem siv rau hauv cov roj acidic thiab roj ib puag ncig uas muaj hydrogen sulfide (H₂S)?
A: Yog. TP316L stainless hlau yog tsim rau me me mus rau nruab nrab qaub kev pab cuam. Rau qhov hnyav H₂S ib puag ncig, xaiv cov khoom siv yuav tsum ua raws NACE MR0175 / ISO 15156 cov cai, nrog Duplex 2205 lossis npib tsib xee alloys pom zoo kom muaj kev tiv thaiv corrosion ntau dua.
