Kev lag luam tshuaj lom neeg thoob ntiaj teb tab tom hloov kho mus rau qhov loj - nplai, ntsuab, thiab ntev - kev loj hlob. Chlor alkali PTA, Hauv thaj chaw ntub dej metallurgy, zoo tshuaj engineering, thiab lwm yam lag luam, feem ntau muaj zog corrosive tej yam kev mob xws li muaj zog acids, muaj zog alkalis, thiab siab chloride ions. Cov khoom siv carbon steel thiab stainless hlau ib txwm muaj lub neej luv luv, cov nqi kho mob siab, thiab muaj kev nyab xeeb siab. Titanium tubes tau dhau los ua cov khoom tseem ceeb tshaj plaws rau cov khoom siv tshuaj lom neeg loj vim lawv cov plaub yam tseem ceeb ntawm qhov kawg corrosion tsis kam, siab zog, hnav, thiab kev pab lub neej ntev. BThe tshuaj siv ntawm titanium yeeb nkab hauv Tianjin kev ua lag luam yog 15,000 tons hauv 2014, suav txog 30% ntawm tag nrho cov khoom siv titanium; Nws yog qhov kev cia siab kwv yees tias lub ntiaj teb cov tshuaj titanium yeeb nkab yuav loj hlob los ntawm 6.2% ib xyoos ib xyoos los ntawm 2026 txog 2030, thiab ib pawg titanium yeeb nkab yuav ntim ntawm qhov project loj yuav ntau dua 1000 tons.
Rau daim ntawv thov ntawm American tus qauv GR1 / GR2 ntshiab titanium, GR7 (Ti-0.2Pd), thiab GR12 (Ti-0.3Mo-0.8Ni) nyob rau hauv loj chemical engineering tej yaam num, thiab yuav khiav mus rau huab ua hauj lwm ib puag ncig, cov hlab tau ntsib nrog ASTM B338 (heat exchanger raj) thiab ASTM B{0.less tubes (se specifications)
1, Chlor alkali engineering: "kev xaiv lub neej ntev" rau siab - kub thiab muaj zog alkali ua haujlwm
Lub ntiaj teb-chav kawm chlor alkali kev sib koom ua ke project (nrog rau kev tso tawm txhua xyoo ntawm 1.2 lab tons ntawm caustic soda) siv GR2 titanium welded kav (Φ 25 × 1.2mm, ntev 6m) ua cov cua txias rau cov txheej txheem electrolysis, uas tuaj yeem tiv taus corrosion los ntawm cov alkaline muaj zog ntawm 3% 90 degree. Thawj 316L stainless hlau raj muaj lub neej ntev ntawm 2-3 xyoos nkaus xwb, thaum lub titanium raj tau ua haujlwm tsis tu ncua rau 12 xyoo yam tsis muaj qhov xau, txo tus nqi txij nkawm los ntawm 85% thiab txo qis cov khoom lag luam poob los ntawm ntau dua 20 lab yuan ib xyoos twg; Qhov project ib txhij siv GR7 titanium raj los kho cov tshuaj chloride uas muaj cov dej ntsev, uas txhim kho pitting corrosion kuj los ntawm 40%.
2, PTA Engineering: Qhov "Txhim Kho Thaum tshav kub kub Exchange Core" ntawm High Temperature Acetic Acid Medium
Lub oxidation chav tsev kub exchanger ntawm lub loj -scale PTA nroj tsuag (nrog rau ib xyoos twg ntawm 2.5 lab tons) siv GR2 titanium seamless hlab (Φ 19 × 1.0mm, U-zoo li tus raj pob), uas muaj peev xwm tiv taus corrosive media ntawm 220℃thiab 95% acetic acid. Piv nrog rau cov hlau tsis muaj steel, titanium raj muaj 12% nce hauv kev hloov pauv hluav taws xob thiab 15% txo qis hauv kev siv zog; Cov cuab yeej siv tau ua haujlwm tsis tu ncua rau 8 xyoo yam tsis muaj kev ntsuas los yog corrosion, thiab cov khoom purity yog ruaj khov ntawm 99.9%, zam qhov kev pheej hmoo ntawm cov hlau ion muaj kuab paug.
3, Wet metallurgical engineering: ib qho "ruaj khov barrier" rau siab acid thiab chlorine uas muaj ib puag ncig
Ib qho loj - nplai ntub tooj liab smelting project nyob rau hauv teb chaws Africa (nrog rau txhua xyoo tso zis ntawm 300000 tons ntawm cathode tooj liab) siv GR12 titanium hlab (Φ 50 × 2.0mm, seamless) rau leachate tshav kub pauv thiab tsheb thauj mus los, uas muaj peev xwm tiv taus acidic daws uas muaj ⁻ 2 ⁺℃thiab pH=1.5. Titanium cov kav dej muaj kev tiv thaiv zoo rau kev ntxhov siab corrosion cracking (SCC), ua tiav cov teeb meem ntawm perforation thiab to ntawm stainless hlau kav hauv 3 lub hlis. Cov cuab yeej siv lub neej txuas ntxiv mus rau 15 xyoo, thiab cov tooj liab rov qab tau nce 1.2%.
4, Soda tshauv engineering: lub zog-txuag kev hloov kho tshiab rau cov xov xwm ntsev siab
Lub chav ammonia ntauwd cua kub exchanger nyob rau hauv ib tug soda tshauv nroj tsuag nyob rau hauv lub tebchaws United States hloov cam khwb cia hlau kav nrog GR2 titanium kav (Φ 38 × 1.5mm) los kho sodium chloride / ammonium chloride tov media. Lub titanium raj tau nyob twj ywm rau 5 xyoos, nrog rau 25% nce nyob rau hauv lub tshav kub hloov mus rau lub peev xwm thiab 40% txo cov khoom hnyav, txo qis lub hauv paus load thiab lub zog noj.
Core parameters thiab manufacturers zoo
