2. Zog & Cryogenic kua
Liquefied Natural Gas (LNG) / Liquefied Ethylene:
Khoom siv: 304L / 316L Austenitic Stainless Hlau (tiv taus rau qhov kub thiab txias mus rau -196 degree; tsis muaj qhov txias txias)
Muaj nuj nqi: Cryogenic kua-theem loading/unloading, vapor xa rov qab, nitrogen purging rau anti-icing
Liquefied Petroleum Gas (LPG): Siab-siab, qis-kub dej xws li propane, butane, thiab lwm yam.
3. Tshuaj zoo & Tshuaj
High -cov tshuaj purity, reagents, cov kuab tshuaj (tiv thaiv cov hlau ion paug)
Pharmaceuticals / Biologics:
Qhov yuav tsum tau muaj: 316L cov khoom siv nrog sab hauv thiab sab nrauv daim iav polishing (Ra Tsawg dua lossis sib npaug ntawm 0.8 μm); yooj yim los ntxuav thiab sterilize (CIP / SIP)
Daim ntaub ntawv: Chaw thau khoom / tshem tawm ntawm APIs (Cov Khoom Siv Tshuaj Ua Haujlwm), Dej rau Txhaj Tshuaj (WFI), syrups, thiab cov kua dej tsis muaj menyuam
4. Khoom noj khoom haus & dej haus (Sanitary Grade)
Siv tau Media:
Cov roj uas siv tau, syrups, soy sauce, vinegar, dej cawv, mis nyuj, kua txiv hmab txiv ntoo, thiab lwm yam.
Yam yuav tsum tau muaj: 304/316 zaub mov- qib polishing; tsis muaj cov ces kaum tuag/crevices; ua raws li FDA / GB qauv; tiv thaiv kab mob loj hlob
5. Chaw nres nkoj / Terminals / Offshore Platforms
Marine Loading Arms:
Khoom siv: 316L (tiv taus chloride ion corrosion los ntawm seawater; ntsev - tshuaj tiv thaiv)
Daim ntawv thov: Nkoj - mus rau - ntug hiav txwv thauj khoom / tshem tawm cov roj av, roj av, tshuaj, thiab dej hiav txwv
6. Lwm yam kev lag luam
Kev kho dej: dej ntshiab, dej khib nyiab, acidic / alkaline effluent
Pulp & Ntawv / Printing & Dyeing: Corrosive slurries, tshuaj auxiliaries
Asphalt / Cov Roj Tshwj Xeeb: Siab- viscosity xov xwm xav tau cov cua sov tracing thiab rwb thaiv tsev (High-kub resistant stainless hlau)
III. Stainless hlau Loading caj npab vs
Superior to Carbon Steel: Xeb- pov thawj, yuav tsum tsis muaj kev tiv thaiv- kev kho corrosion, lub neej ua haujlwm ntev (15+ xyoo), huv si thiab tsis muaj - paug.
Superior rau Aluminium Alloy: Kev tiv thaiv corrosion ntau dua, tiv taus qhov kub thiab txias, haum rau acidic, alkaline, thiab seawater ib puag ncig.
Superior rau Fluoropolymer-Lined Arms: Cov txheej txheem nruj dua, tiv taus qhov kub thiab txias dua, tshem tawm qhov kev pheej hmoo ntawm cov kab detachment (tab sis tsis tiv taus cov oxidizing acids, xws li concentrated nitric acid).
IV. Cov Txheej Txheem Xaiv Qhov Tseem Ceeb (Quick Reference)
General Chemicals / Khoom noj khoom haus → 304 Stainless hlau
Media Muaj Chloride Ions / Seawater / Acids & Bases → 316L Stainless Hlau
Cryogenic LNG → 304L / 316L (Cryogenic Qib)
Muaj zog Oxidizing Acids (piv txwv li, Concentrated H₂SO₄, Fuming Nitric Acid) → Tsis txhob xaiv stainless hlau; xaiv hloov rau fluoropolymer- cov caj npab los yog cov alloys tshwj xeeb.
