Thaum li qub yog nthuav tawmCorrosive MedialossisKev Kub Siab, qhov kev xaiv ntawmCov Ntaub Ntawv Trimdhau los ua qhov tseem ceeb. Trim-referring to internal components like the stem, disc, seat, and plug-must withstand chemical attack, erosion, and thermal stress to ensure performance, longevity, and safety. Kev xaiv tsis raug cai tuaj yeem ua rau muaj cov dej xau, kaw, thiab hloov tus nqi.
Kab lus no qhia txog li cas engineers txiav txim siab cov ntaub ntawv trim uas haum rau cov kev pabcuam kev pabcuam.
1. Cov ntsiab lus uas cuam tshuam kev xaiv cov khoom siv
a) Tshuaj Muaj Tshuaj Ntau
Qhov tseem ceeb tshaj plaws yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov kua. Cov kua qaub, chlorides, alkalis, thiab cov kuab tshuaj muaj peev xwm croode txheem cov ntaub ntawv. Kws ua sab lajSib cav sib xyawlossisNACE MR0175 / ISO 15156Cov qauv kom tsis txhob Galvanic lossis pitting corrosion.
b) Kev ua haujlwm kub thiab siab
Thaum kub siab (feem ntau saum 400℃/ 750 Qib F), ib txwm stainless hlau tsis muaj zog lossis oxidize. Cov kev coj tus cwj pwm nyob rau hauv ob qho tib siThermal nthuav davthiabSiab Cyclingyog kwv yees kom tsis txhob deformation lossis tawg.
c) Cov Khoom Siv Neeg Kho Tshuab
Hnav tsis kam, hardness, thiab tensile lub zog yog txiav txim siab - tsis muaj kev txaus ntshai.Nyuaj - tig rov qabNrog cobalt -} Raws alloys (piv txwv li, stellite) feem ntau siv rau kev pabcuam ntev.
d) Cov Qauv Kev Cai thiab Kev Lag Luam
API, ASME, thiab ASTM cov qauv txhais tau cov qauv kev siv nyiaj txiag siv rau qee chav kev pabcuam. E6 -}}} Cov neeg siv hauv cov roj, roj, thiab petrochemical cov cai feem ntau thovCov khoom siv traceability thiab ntawv pov thawj.
2. Cov ntaub ntawv trim ntau thiab lawv cov ntawv thov
| Khoom | Cov Khoom Siv | Kev Siv Cov Ntaub Ntawv |
|---|---|---|
| 316 SS | Zoo corrosion tsis kam | General - lub hom phiaj, cov kev pab cuam chlubly |
| Tus mlom | Zoo heev rau cov acids thiab seawater | Tubrog Nkoj, Sour Gas |
| Lawg | Muaj zog tiv thaiv oxidizers thiab acids | Chlorine, Cov Nroj Tsuag |
| Tsis zoo | Withstands huab cua sov heev thiab kev ntxhov siab | Lub zog tiam, siab - Temp Chav |
| Stellite (CICL TXHAWB) | Heev nyuaj, kev yaig - tsis kam | Rooj zaum, plugs hauv erosive media |
| Alloy 20 | Acid - tsis kam | Sulfuric Acid Service |
| Titanium | Lub teeb yuag, muaj kev txhim kho corrosion - tsis kam | Txhoj puab heev chlorides, seawater |
3. TRIM NUMALLING
HauvAPI 600thiabAPI 602, "Luas lej luas" txhais cov qauv sib xyaw ntawm kav, lub rooj zaum, thiab cov ntaub ntawv disc. Piv txwv li:
- Trim 5: Monel luas
- Luas 8: 410 ss nyuaj - ntsej muag nrog stellite
- Trim 12: 316 Ss lub rooj / Disc nrog nyuaj -} ntsej muag
Qhov no yooj yim sib txuas lus nruab nrab ntawm cov neeg yuav khoom thiab cov tuam ntxhab thiab ua kom pom tseeb kev ua raws.
4. Kev Tawm Tsam Tawm Hauv Trim Xaiv
- Laser - cladded trim:Ua kom muaj qhov tseeb thiab tsev pheeb suab zog rau lub zog nyuaj - Nrhiav alloys alloys.
- Ceramic Luas:Siv nyob rau hauv huab cua puas thiab slurry cov ntawv thov.
- Lub tsho ntev zog:Self -}} {{-} fouling Txheej ci yog nyob rau hauv kev txhim kho kom tau ua kom ruaj khov.
- Cov Tshoob Ntxhais Quav:Simulates hnav thiab cov khoom coj tus cwj pwm ua ntej tsim khoom.
Xaiv txoj caiVALVE TRIM COV KHOOM SIVyog qhov sib npaug ntawm kev ntsuas pa, kub, siab, thiab hnav txhua yam hnav. Thaum cov alloys nce ntau Alloys thiab cov txheej txheej yuav tsa tus nqi pib, lawv tau txo qis downtime thiab tsis muaj kev pheej hmoo nyob hauv ib puag ncig. Kev Koom Tes Ua Haujlwm Thaum Ntxov Nrog Cov Khoom Siv Khoom Siv lossis Cov Khoom Siv Hluav Taws Xob ua kom muaj kev ua tau zoo thiab kev tswj hwm ua raws.
