Cov yam ntxwv ntawm cov kav dej rau roj av tawg, chiv, thiab tshuaj lom neeg kev lag luam

Cov kav hlau rau cov roj av, petrochemical, thiab tshuaj lom neeg kev lag luam (xws li kev lag luam thee chemical), feem ntau hu ua cov kav hlau rau kev lag luam tshuaj, feem ntau xa mus rau cov kav hlau siv hauv kev lag luam petrochemical, suav nrog roj av refining, tshuaj fiber ntau, thee chemical kev lag luam, tshuaj. kev lag luam, thiab chiv ntau lawm. Raws li kev tsim cov yeeb nkab steel, lawv tau muab faib ua seamless steel kav thiab welded kav. Raws li hom hlau, nws tuaj yeem muab faib ua carbon steel kav, alloy steel kav, stainless hlau kav, nrog rau cov kav hlau sib xyaw siv dav hauv xyoo tas los no. Vim lub fact tias lub ntsiab lub cev thiab cov tshuaj tiv thaiv nyob rau hauv peb chemical ntau lawm txheej txheem yog nqa tawm nyob rau hauv tshwj xeeb pressures thiab kub. Cov khoom siv raw, cov txheej txheem tshuaj tiv thaiv, thiab cov khoom lag luam txhua tus muaj qhov xav tau ntawm qhov kub thiab txias, thiab cov khoom siv raw, cov txheej txheem tshuaj tiv thaiv, thiab cov khoom txhua tus muaj qee qhov kev corrosiveness. Yog li ntawd, muaj qee yam kev cai rau cov kav hlau siv hauv kev tsim tshuaj lom neeg.

Tus yam ntxwv ntawm Tuam Tshoj lub zog kev pab cuam yog nplua nuj nyob rau hauv roj thiab tsawg thee. Siv Tuam Tshoj cov peev txheej thee ntau thiab siv thee liquefaction thev naus laus zis los hloov cov thee rau hauv cov roj ua kua zoo yog ib txoj hauv kev zoo rau Tuam Tshoj los siv cov thee thermal, tshwj xeeb tshaj yog cov hlau sulfur.

Direct thee liquefaction yog cov txheej txheem hydrogenation nyob rau hauv kev kub siab thiab kub, yog li cov txheej txheem cov cuab yeej thiab cov ntaub ntawv yuav tsum muaj siab tsis kam thiab hydrogen corrosion kuj nyob rau hauv hydrogen tseem ceeb heev. Tsis tas li ntawd, cov ntaub ntawv ncaj qha liquefied muaj cov khoom sib xws xws li thee thiab catalysts, yog li nws yog ib qho tsim nyog los daws cov teeb meem xws li sedimentation, hnav, thiab sealing los ntawm cov khoom ua tiav. Siv cov kav dej loj loj seamless steel kav rau inclined conveying tuaj yeem cuam tshuam cov theem sib cais ntawm slurry thiab residue nyob rau hauv cov yeeb nkab conveying thaum tus txheej txheem. Phab ntsa thickness ntawm seamless steel kav yuav ncav cuag li 105 hli
