Background material
Lub chaw hloov roj roj tshiab ntawm lub tuam txhab petrochemical xav tau lub tank ammonia vapor buffer, uas nws cov ntaub ntawv suav nrog NH3 thiab dej, nrog rau kab H2S thiab CO2, Vim tiastitanium alloymuaj kev tiv thaiv corrosion zoo heev, siab -kub tsis kam, thiab lub zog siab, nws lub zog tshwj xeeb yog 3 npaug ntawm cov hlau tsis muaj steel. Yog li ntawd, tus tswv xaiv titanium los tsim cov khoom siv, uas yuav tsum tau ua raws li qhov yuav tsum tau uaTSG 21-2016 Supervision Regulation on Safety Technologyntawm cov hlab ntsha ruaj khov thiabJB / T 4745-2002 titanium welded nkoj. Cov khoom siv ntawm lub ntsiab qhov siab ntawm cov cuab yeej yog TA3, qhov tsim siab yog 0.6 MPa, qhov tsim kub yog 140 degree, thiab qhov nruab nrab qhov nruab nrab txhua hli qhov kub ntawm qhov chaw siv yog - 16.1 degree (qhov Kev txwv qis ntawm qhov tso cai kub ntawm titanium yog - 269 degree, qhov txwv sab saud yog 300 degree, uas ua tau raws li qhov xav tau ntawm qhov kub thiab txias).
Requirements for plates and pipes
Lub thawv xav kom cov phiaj thiab cov kav dej yuav tsum tau ua los ntawm TA3 titanium, tus qauv tsim ntawmtitanium thiab titanium alloy phajyogGB / T 3621-2007 titanium thiab titanium alloy phaj; Cov txheej txheem tsim khoom ntawmtitanium cevyogGB / T 3624-2010 titanium thiab titanium alloy seamless yeeb nkab. Cov khoom siv raws li txoj cai yuav tsum tau annealing (Lavxias teb sab titanium yuav tsum tsis txhob siv los hloov) thiab seamless yeeb nkab yuav tsum tau raws li qhov yuav tsum tau ntawm JB / T 4745-2002 tus qauv tsim. Txij li JB / T 4745-2002 tus qauv tau ua tiav ua ntej, tus thawj saib xyuas tuaj yeem hais kom tus tsim qauv ntxiv cov lus piav qhia ntawm kev siv cov qauv tshiab ntawm cov khoom siv.

Ua ntej lubtitanium phajmuab tso rau hauv cia, tshuaj muaj pes tsawg leeg, txhua yam khoom, thiab cov txheej txheem yuav tsum tau soj ntsuam raws li qhov yuav tsum tau ntawm GB / T 3621-2007. Tshawb xyuas qhov zoo li qhov zoo thiab qhov sib txawv ntawm daim hlau ib los ntawm ib qho. Thaum qhov loj thiab cov tsos zoo tsis tsim nyog, lub phaj tsis tsim nyog; Thaum cov tshuaj muaj pes tsawg leeg tsis tsim nyog, batch ntawm cov khoom tsis tsim nyog. Siv 2 daim ntawv los ntawm txhua pawg ntawm daim phiaj, tom qab ntawd coj 2 cov qauv hloov pauv ntawm txhua lub phaj, thiab sim cov khoom siv thiab cov txheej txheem ntawm 4 cov qauv (yog tias tsuas muaj 1 phaj, coj 2 cov qauv) raws li. Yog tias ib qho qauv tsis tsim nyog, ob npaug ntawm cov qauv yuav tsum raug coj mus kuaj dua. Yog tias ib qho qauv tseem tsis tsim nyog, batch ntawm daim hlau yuav tsum tsis tsim nyog. Lub sijhawm no, tus neeg xa khoom raug tso cai rov tshuaj xyuas cov khoom tsis tsim nyog ib zaug los ntawm ib qho, thiab cov khoom tsim nyog tau muab rov ua dua thiab khaws cia hauv cov khoom siv. Cov kav dej yuav tsum raug soj ntsuam zoo sib xws raws li GB / T 3624-2010 tus qauv, thiab lawv tuaj yeem raug suav thiab muab tso rau hauv cia tsuas yog tom qab dhau qhov kev tshuaj xyuas.
