Titanium flanges,nrog rau lawv cov corrosion kuj, muaj zog tshwj xeeb, thiab dav -kub- thaj tsam ruaj khov, tau dhau los ua cov ntaub ntawv nyiam rau ob qhov tseem ceeb hauv kev kho kom zoo nkauj thiab tshuaj nroj tsuag: thaj chaw tshuaj tiv thaiv thiab cov dej qaub stripping unit. Kev xaiv meej ntawm titanium flanges yog lub hauv paus rau kev ua kom lub sijhawm ntev -, kev ua haujlwm nyab xeeb ntawm chav tsev. Raws li kev ua haujlwm tiag tiag, kab lus no qhia txog cov laj thawj tom qab titanium flange xaiv.
PART.01 Kev soj ntsuam ntawm Cov Txheej Txheem Ua Haujlwm Tseem Ceeb
1. Teb Chaws (xws li, Catalytic Cracking, Hydrocracking, Reforming Reactors)
- Muaj cov hydrogen sulfide (H₂S), chlorides, naphthenic acid, hydrogen, thiab lwm yam, nrog rau qhov muaj zog corrosivity nyob rau hauv qhov kub thiab txias.
- Kub: 300-600 degree; Siab: Ob peb MPa rau kaum MPa.
- Kev pheej hmoo suav nrog hydrogen embrittlement, sulfide stress corrosion cracking (SSC), thiab siab -kub sulfur corrosion.
- Cov ntaub ntawv yuav tsum muaj kev sib xyaw ua ke ntawm siab - kub lub zog, nkag siab, thiab tsis kam mus rau txoj kev corrosion.
2. Cov dej qab zib Stripping Unit
- Kho cov dej khib nyiab uas muaj hydrogen sulfide, ammonia, cyanides, thiab phenols. pH tsawg, thiab cov ntsiab lus chloride ion tuaj yeem siab heev.
- Kub: 100-150 degree; Siab: Nruab nrab.
- Qhov nruab nrab yog rhiab rau pitting thiab crevice corrosion.
- Flange kev sib txuas yog qhov ua rau corrosion perforation vim nruab nrab stagnation nyob rau hauv crevices, yuav tsum tau cov ntaub ntawv uas zoo heev kuj rau pitting thiab crevice corrosion.
PART.02 Tsib Core Dimensions rau Titanium Flange Xaiv
1. Khoom Qib
- TA2 (Gr2):Economical thiab tswv yim ntshiab titanium. Haum rau oxidizing ib puag ncig (xws li dej hiav txwv, nitric acid, ntub chlorine gas) nrog zoo corrosion kuj. Dav siv nyob rau hauv cov dej qaub stripping thiab chloride ion ib puag ncig.
- TA9 (Gr7) / TA10 (Gr12):Los ntawm kev ntxiv palladium los yog molybdenum thiab npib tsib xee rau lub hauv paus TA2, cov qib no ua kom muaj zog tiv thaiv kom tsis txhob muaj cov kua qaub (xws li, dilute sulfuric acid, hydrochloric acid) thiab siab - kub, tsis muaj zog ntawm cov xov xwm. Haum rau cov complex corrosive ib puag ncig nyob rau hauv cov tshuaj tiv thaiv zones.
- TC4 (Gr5) Titanium Alloy:Lub zog siab thiab zoo heev creep kuj, nrog lub zog tawm los tshaj 900 MPa. Haum rau qhov chaw hauv cheeb tsam cov tshuaj tiv thaiv uas xav tau cov neeg kho tshuab siab zog nyob rau hauv qhov kub thiab txias.
2. Hom qauv thiab sealing ntsej muag
- Weld Neck Flange (WN):Haum rau siab -siab, siab- kub, thiab hnyav cyclic. Lub integrated tapered hub muab ib tug du kev hloov, txo cov kev ntxhov siab concentration, thiab muaj zoo heev qaug zog thiab kev co kuj. Nws yog tus qauv kev teeb tsa rau siab - kub thiab siab - cov kav dej siab hauv thaj chaw tshuaj tiv thaiv.
- Lap Joint Flange (SO/LJ):Tsim nyog rau daim ntawv thov uas yuav tsum tau nquag disassembly rau kev saib xyuas lossis siv nrog cov khoom siv tshwj xeeb, cov yeeb nkab kim kom txuag tau tus nqi, tab sis muaj lub siab qis dua - cov kabmob muaj peev xwm.
- Sealing ntsej muag hom:
- Tsa ntsej muag (RF):Feem ntau, tab sis ceev faj yog xav tau rau cov khoom siv hluav taws xob, hluav taws xob tawg, lossis cov xov xwm muaj kev phom sij heev.
- Txiv neej & Poj Niam ntsej muag (MFM) / Tus nplaig & Groove ntsej muag (TG):Pom zoo rau kev xau- cov xov xwm tsis zoo, muaj kev phom sij. Tus kheej- sealing kev txiav txim tiv thaiv gasket tshuab- tawm, kom ntseeg tau tias sealing txhim khu kev qha.
- Ring Type Joint (RJ):Tshwj xeeb yog tsim los rau siab - kev siv siab, siv lub nplhaib hlau gasket. Siv nyob rau hauv ultra- siab- qhov chaw siab ntawm thaj chaw tshuaj tiv thaiv.
3. Qib Siab thiab Forging Level
- Txiav txim siab Nominal Pressure (PN) lossis Chav Kawm raws li kev tsim siab thiab kub.
- Forging Level yog qhov ntsuas qhov tseem ceeb:Raws li cov qauv (xws li, JB4726), rau titanium flanges nrog PN Ntau dua lossis sib npaug ntawm 10.0MPa lossis kev ua haujlwm kub tsawg dua lossis sib npaug rau -20 degree, cov forgings yuav tsum ua tau raws li Qib Ⅲ lossis siab dua, ua kom cov qauv ntom ntom tsis muaj qhov tsis xws luag.
4. Cov qauv thiab ntawv pov thawj
- Xyuas kom cov khoom flange ua raws li cov qauv thoob ntiaj teb lossis lub teb chaws xav tau los ntawm qhov project, xws li ASME B16.5, GB / T 9112, thiab lwm yam.
- Muaj daim ntawv pov thawj cov ntaub ntawv tiav, cov ntaub ntawv kho cua sov, thiab tsis yog -cov ntawv ceeb toom kev puas tsuaj (UT/PT).
5. Kev tsim khoom thiab kev kho deg
- Forging yog superior rau casting:Forging ua rau cov qauv denser thiab cov khoom siv kho tshuab zoo dua, ua rau nws nyiam cov txheej txheem rau siab -siab flanges.
- Nto tiav:Lub ntsej muag roughness ntawm lub ntsej muag sealing yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias muaj kev sib khi zoo.
PART.03 Cov ntaub ntawv ceev ceev rau ntu-Cov lus pom zoo xaiv tshwj xeeb
Raws li tus kws tshaj lij nrog ob xyoo caum ntawm kev koom tes sib sib zog nqus hauv kev lag luam titanium, Lihua Titanium tsis yog tsuas yog muab siab -cov khoom zoo titanium flange uas ua tau raws li cov qauv thoob ntiaj teb tab sis kuj xav ua koj "Cov Khoom Pab Tswv Yim." Txuas lub ntiaj teb, thiab tseem ceeb tshaj, txuas kev nyab xeeb. Cia txhua qhov kev xaiv uas koj ua dhau los ua qhov lav zoo rau qhov ruaj khov, ntev - lub sijhawm, thiab ua haujlwm tau zoo ntawm koj lub tsev.
Raws li ib tug"Specialized thiab Sophisticated" enterprisethiab atsim kev lag luam saum toj qhov loj me hauv Shaanxi Xeev, Lihua Titanium tau tsom mus rau titanium flanges rau 20 xyoo, pab ntau tshaj 56,000 lub lag luam hauv kev daws teeb meem kev lag luam corrosion. Yog xav paub ntxiv, thov ua raws li peb tus lej WeChat pej xeem "Lihua Titanium," tso koj lub tuam txhab npe thiab cov ntaub ntawv tiv tauj, thiab peb yuav muab koj cov kws tshaj lij los tiv thaiv- kev daws teeb meem corrosion.
