SILI LE TETEE A'E MA LE UMA
Titanium tubular heat exchangers e ta'uta'ua ona o lo latou malosi fa'afefeteina, ma fa'alelei ai mo si'osi'omaga faigata tau pisinisi. O luga ole titanium alloy e fausia ai se vaega mafiafia ole oxide (TiO₂) e fa'amavae lelei ai acids, alkalis, salts, ma ions chloride. O lenei tete'e a'a e sili ona talafeagai mo siosiomaga e pei ole hydrochloric acid (concentration<3%) and other aggressive media. Additionally, titanium alloys maintain over 90% strength at 250°C and can withstand short-term temperatures up to 500°C, ensuring reliability under high-temperature conditions. With a service life exceeding 20 years, titanium heat exchangers outperform stainless steel (5-8 years) and nickel-based alloys (10-15 years), significantly reducing long-term maintenance and replacement costs.
LELEI MA LE FA'ASAOINA O LE MALO
O le mamanu fou o titanium tubular heat exchangers o lo'o tu'ufa'atasia ai pa'u li'o ma fesuia'i -fa'amau fa'apa'au, fa'asili ai le lelei o le fa'aliliuina o le vevela i le 25% ae fa'aitiitia ai le mamafa i le 18%. O le fa'aogaina o -lua fa'afeagai fa'afeagai ma le fa'ata'ita'iga umi fa'au'au fa'alelei (e mafai ona fa'atulagaina mai le 0.5 i le 12 mita) e fa'amalie atili ai le fa'atinoga o le vevela. Faʻamatalaga faʻataʻitaʻiga o loʻo faʻaalia ai faʻatasi ai ma tekinolosi faʻaleleia le vevesi, o le faʻafefe o le vevela o le titanium exchangers vevela e mafai ona oʻo atu i le 14,000 W / (m² · tikeri), e sili atu nai lo le 2,000-3,000 W / (m · tikeri) masani o fefaʻatauaʻiga vevela i totonu o aiga. I le fa'aogaina o vai vevela, o lenei mamanu e mafai ai ona fa'a'ele'ele atoatoa le ausa i totonu o le paipa fa'apa'au, fa'aitiitia ai le mana'oga mo le fa'aliliuina o le vevela lona lua ma fa'asaoina le malosi tele.
FUAFUAGA FA'AMATOTO, TETEE MILI MAUA, MA LE TAUSIGA FA'AVAE
Titanium tubular heat exchangers o lo'o iai se fausaga fa'apitoa, ma lona voluma e na'o le 1/5 le tele o atigi fa'atusa -ma-tube heat exchanger, fa'asaoina le avanoa ma fa'aitiitia ai tupe fa'afaigaluega. O latou mamanu mama e faafaigofieina ai le faʻapipiʻiina, talepe, ma le faʻamamaina. O le faʻaogaina o ulu faʻapipiʻi ma le faʻalauteleina o tekinolosi faʻalauteleina e mafai ai ona latou tatalia le mamafa e oʻo atu i le 6.4 MPa, faʻaleleia le vaivai. Fa'atopetope-fa'aulu ulu ma masini mata'i masaga fa'atekinolosi fa'aitiitia tau fa'aleleia i tausaga ta'itasi i le 30%. E le gata i lea, o meafaigaluega e mafai ona fesoʻotaʻi saʻo i paipa, faʻaitiitia le faʻapipiʻiina ma faʻaauau tupe faʻaalu.

PISINISI KEMIMI
I le gaosiga o vaila'au, e taua tele le fa'atumauina o va'aiga o le vevela ma'oti. Titanium tubular heat exchangers e ausia nei manaʻoga ma le pulea lelei o le vevela ma le faʻaogaina o le vevela sili atu. Mo se faʻataʻitaʻiga, i totonu o se fale gaosi PTA, o loʻo faʻaaogaina le vevela o le titanium mo le faʻamafanafanaina o le reactor, toe faʻaleleia o le vevela, ma le toe faʻaleleia o koluma, faʻaleleia le faʻaogaina o le malosi e 12%. I totonu o se vaega toe fuata'i faifaipea, o le suiina o se fa'a'avevela masani -ulu fa'a'avevela i se fa'a'avevela titanium tubular na fo'ia ai fa'afitauli o le le lava le malosi o le mālūlū ma fa'aitiitia ai le eseesega o le vevela -i'uga mai le 54 tikeri i le 43 tikeri. E le gata na aveesea ai le saogalemu o tane e teu ai suauu ae na siitia ai foi le vevela o le ulu o le mea'ai fa'ameamea a'o le'i-hydrogenation, fa'aitiitia le uta i luga o le ogaumu fa'avevela ma fa'aititia ai le aofa'i o le malosi. O le taimi e toe totogi ai tupe fa'afaigaluega mo ia fa'afouga e masani lava e tolu masina, e maua ai le tele o fa'amanuiaga tau tamaoaiga.
PETROLEUM MA MALOSI
I le suau'u suau'u, titanium tubular exchangers vevela o loʻo faʻaaogaina mo le faʻamafanafanaina o le suauʻu mama, faʻamafanafanaga o oloa, ma le faʻafefe o kesi. I totonu o iunite faʻafouina catalytic, e mafai ona oʻo atu i le 95%. I le fa'aogaina o le malosi, e pei o pamu vevela vevela ma fa'aogaina o le la, fa'aliliu vevela titanium e mafai ai ona fa'aliliu lelei le malosi. O lo latou tetee ma le tumau e talafeagai ai mo faiga fa'amama vai i totonu o va'a ma fale faaniukilia. I se tasi tulaga, o se fale kemikolo 200,000-ton / tausaga na ausia le 8% -12% faʻasaoina o le malosi e ala i le fesuiaʻi i titanium tubular heat exchangers, toe faʻaleleia le tau muamua o tupe faʻafaigaluega i totonu o le tolu tausaga.
PUIPUIA O LE SI'OSIOMAGA MA ISI FA'AGA
O le fa'a'avevela o le titanium e iai sona sao taua i le puipuiga o le si'osi'omaga, o lo'o avea ma fa'avevela po'o fa'alili i faiga fa'a'asu e fa'aleleia ai le fa'aogaina o le malosi. O lo'o fa'aaogaina fo'i i vaila'au, gaosiga o mea'ai, ma isi fa'alapotopotoga e taua tele ai le fa'ama'i ma le tumama. Mo se faʻataʻitaʻiga, i le gaosiga o vailaʻau, e faʻamautinoa e le faʻaogaina o le vevela o le titanium e leai se faʻamaʻi uʻamea, faʻamalieina tulaga tumama.
