Tiag -Kev Kawm Txuj Ci Ntiaj Teb
Case 1: Yog vim li cas 316L ua tsis tiav hauv Seawater Cooling Systems Thaum 254SMO ciaj sia
"Vim li cas 316L stainless hlau tseem nyob hauv dej hiav txwv txawm tias nws hu ua qib marine?"
Yog vim li cas yog tias 316L tsuas yog nruab nrab ntawm cov tshuaj chloride corrosion.
Ib yam dej hiav txwv txias system muaj:
- Chloride ions: 18,000-20,000 ppm
- Dissolved oxygen
- Biological deposits
- Kub hloov pauv
Raws li cov xwm txheej no, 316L tuaj yeem ntsib:
- Weld tshav kub cuam tshuam cheeb tsam corrosion
- Crevice corrosion nyob rau hauv clamps
- Pitting ncig thaj chaw weld
254SMO ua tau zoo dua vim tias:
- Siab dua Mo txhim kho qhov tsis kam.
- High nitrogen stabilizes lub passive txheej.
- Tus nqi siab dua PREN ncua sijhawm chloride nres.
Case 2: "Yuav tau 254SMO hloov Inconel 625 kom txo tau qhov project?
Rau qhov kub hauv qab li ntawm 300 degree: 254SMO feem ntau tuaj yeem hloov cov nickel alloys kim.
Cov lus teb nyob ntawm qhov kub thiab txias thiab corrosion.
Case 3: Qhov teeb meem ntawm "chemistry-tsuas yog" MTC ntawv pov thawj
Ob peb lub mills muab S31254 welded yeeb nkab nrog zeb xeem daim ntawv pov thawj uas qhia cov tshuaj muaj pes tsawg leeg kom raug tab sis tshem tawm cov tshuaj annealing tsis. Cov khoom uas tsis tau raug kho kom raug-annealed (1150-1200 deg C, dej quench) khaws cov intermetallic precipitates los ntawm cov txheej txheem vuam, txo CPT los ntawm 15-20 deg C. MTC yuav tsum muaj xws li qhov kub thiab txias, tuav lub sij hawm, thiab txias txoj kev. Yog tias cov no tsis tau tshaj tawm, thov daim ntawv pov thawj kho cua sov ntxiv.
Case 4: Southeast Asian FGD tej yaam num
Cov ntaub ntawv tshaj tawm los ntawm Cov Neeg Esxias Qab Teb Hnub Tuaj FGD tej yaam num qhia txog kev txhim kho corrosion nyob rau hauv cov deposits raws li kev ua tsis tau tejyam hom - tsis pitting ntawm dawb paug qhov chaw. Slurry buildup ntawm cov yeeb nkab tsis tshua muaj cov ntsiab lus, hauv qab gaskets, thiab ntawm flange ntsej muag tsim cov tshuaj chloride concentration ntawm cov hlwb uas tsav CCT hauv qab tus qauv tsim. Txoj kev kho kom zoo tsis yog kho kom zoo dua cov hlau, tab sis txhim kho cov dej geometry, txo qis txoj kab rov tav khiav, thiab qhia tag nrho - nkag welds nrog cov hauv paus hniav zoo kom tshem tawm cov crevices sab hauv.
Case 5: Coastal Chemical Plant Failure Case
- Teeb meem: ntxov pitting corrosion thiab localized weld decay tshwm sim nyob rau hauv ib tug ntug dej hiav txwv tshuaj cog siv tus qauv 316L welded kav tuav dej txias nrog 35,000 ppm chlorides ntawm 45 degree.
- Kev Tshawb Fawb Txog Kev Tshawb Fawb: 316L tsis muaj molybdenum txaus los tiv thaiv sov, aerated chloride daws, uas ua rau cov chaw ua haujlwm pitting raws cov cua sov- thaj tsam cuam tshuam (HAZ) ntawm longitudinal ERW welds.
- Kev daws teeb meem engineering: Lub chaw hloov pauv tsis ua haujlwm nrog ASTM A358 254SMO EFW welded kav. Qhov siab dua PREN (Ntau dua lossis sib npaug ntawm 42) ua tiav tiv thaiv cov tshuaj chloride pitting, txuas ntxiv lub neej kev pabcuam ntawm cov kav dej los ntawm 14 lub hlis mus rau ntau dua 12 xyoo yam tsis muaj kev saib xyuas.
"Yuav ua li cas yog lub sij hawm xa khoom thiab cov txheej txheem kev soj ntsuam vuam (RT/UT) rau cov kav loj -inch 254SMO SAW?"
- Thaum muab khoom siab -kev ua tau zoo stainless hlau welded kav los ntawm cov neeg xa khoom thoob ntiaj teb, ib txwm xav tau 100% radiographic kuaj (RT) ntawm longitudinal / kauv welds rau SAW / EFW kav, nrog rau kev ntsuam xyuas kev sib tshuam (ASTM A262 Practice E).
- Xyuas kom koj tus neeg muag khoom muab cov ntaub ntawv ua tiav los ntawm melting (AOD + VOD) mus rau qhov kawg tsis yog -kev kuaj kev puas tsuaj (NDT).
