Hauv kev lag luam petrochemical, SA204 Qib B yog qhov kev xaiv tseem ceeb rau kev tsim cov khoom hnyav-cov haujlwm ua haujlwm xws li hydro-reactors, distillation kab, thiab siab -siab sib cais. Cov Cheebtsam no yuav tsum ua haujlwm nyob rau hauv kev ntxhov siab heev thaum muaj cov tshuaj volatile; 0.5% molybdenum cov ntsiab lus xyuas kom meej tias cov phab ntsa ntawm cov hlab ntsha tiv thaiv deformation (creep) ntau xyoo dhau los ntawm kev pabcuam tas mus li, tswj xyuas kev ncaj ncees ntawm cov txheej txheem refinery.

2. Kev tsim hluav taws xob (Thermal & Hydro)

Hauv cov nroj tsuag fossil roj fais fab, cov hlau no ua haujlwm ua lub hauv paus rau chav - lub voj voog cov khoom, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho ntawm boiler chav nruas, superheater headers, thiab siab - siab chav piping. Vim tias cov khoom no yuav tsum tiv taus qhov kub siab txog li 540℃(1000℃F), cov khoom siv lub zog muaj zog tiv thaiv tsis ua haujlwm nyob rau hauv siab - nrawm nrawm. Tsis tas li ntawd, nws yog siv nyob rau hauv loj -scale hydropower tej yaam num rau siab - siab penstocks thiab turbine kauv rooj.

3. Roj & Roj (Sour Service Applications)

Rau kev tshem tawm cov roj thiab roj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj hydrogen sulfide, SA204 Qib B feem ntau siv rau hauv cov hlab ntsha siab.Tom qab tau txais kev kuaj tshwj xeeb HIC (Hydrogen-Induced Cracking) kuaj. Nws qhov zoo tshaj plaws torque toughness thiab tsis kam rau nkig tawg ua rau nws zoo tagnrho rau kev sib sau cov kab, roj - roj separators, thiab sib sib zog nqus -cov khoom siv siab ua haujlwm hauv cov huab cua hnyav, corrosive qhov chaw muaj kev nyab xeeb thiab kev tiv thaiv tsis zoo.

4. Cov Cuab Yeej Hloov & Thermal Systems

Hauv kev lag luam thermal tswj, qib no yog cov khoom siv rau lub plhaub - thiab - raj kub exchangers, condensers, thiab deaerators. Cov khoom siv hluav taws xob hloov hluav taws xob tau dhau los ua cov thermal cycling (cua sov thiab txias), uas tuaj yeem ua rau qaug zog hauv cov qauv carbon steels; SA204 Qib B's alloyed muaj pes tsawg leeg tiv taus qhov thermal qaug zog. Nws yog dav siv nyob rau hauv pov tseg cov cua sov rov qab systems thiab chav tsev - tuav units, ho ncua kev ua hauj lwm lifespan thiab efficiency ntawm lub zog hloov dua siab tshiab systems.
