| Qhov zoo tshaj plaws siv Case | Tshuaj / marine | Kev pabcuam dav dav | Offshore / dej hiav txwv | Roj & roj tsis yog -corrosive |
Corrosion Note: Thaum 316L zoo heev, nws tsis tiv thaiv kev ntxhov siab corrosion cracking (SCC) ntawm qhov kub thiab txias hauv chloride- thaj chaw nplua nuj. Rau qhov kub siab tshaj 60℃hauv siab - dej qab ntsev, xav txog kev kho dua tshiab rau Duplex 2205.
Alloy 316L Flange Application Areas
- Roj & Gas pipelines (offshore risers, subsea systems)
- Seawater systems (desalination nroj tsuag, dej txias)
- Chemical processing plant (acid thiab chloride media)
- Fais fab tuag systems (FGD systems)
- Khoom noj khoom haus & tshuaj kev lag luam (kev tu cev piping systems)
- Marine engineering (nkoj tsim, ballast systems)
Hauv cov dej num hauv ntug dej tiag tiag, 316L flanges feem ntau ua tau zoo dua cov qauv carbon steel thiab 304 stainless hlau thaum raug rau thaj tsam dej hiav txwv.
Common Field Issues:
- Flange lub ntsej muag corrosion vim tsis raug gasket alignment
- Cov dej xau los ntawm bolt so hauv thermal cycling systems
- Kev siv tsis raug ntawm 304 es tsis yog 316L ua rau ua tsis tiav ntxov hauv cov nroj tsuag ntug dej hiav txwv
1. "316L flange tseem xeb hauv dej hiav txwv"
Keeb kwm:
Crevice corrosion nyob rau hauv gasket
Tsis zoo passivation tom qab fabrication
Cov dej hiav txwv nyob ruaj khov
2. "Vim li cas 316L weld discolor?"
Ua rau:
Oxide scale tsim vim muaj cua kub nkag
Tsis muaj cov roj tiv thaiv zoo (argon purity<99.99%)
3. "Yog 316L overkill rau cov tshuab dej?"
Teb:
Rau cov dej haus: feem ntau yog
Rau chlorinated dej hauv nroog: ncaj ncees
4. "Flange to tom qab bolting"
Feem ntau yog vim li cas:
Tsis zoo torque sequence
Gasket misalignment
Nto tiav mismatch (RF vs FF tsis meej pem)
Weldability thiab Fabrication
316L flanges yog ib qho yooj yim stainless hlau Cheebtsam rau vuam.
Cov txheej txheem vuam pom zoo
- GTAW (TIG)
- SMAW (E316L-16)
- GMAW (MIG)
Yuav ua li cas kom tsis txhob Vuam Failures?
1. Tiv thaiv kom tsis txhob hnov qab
Siv cov khoom siv hluav taws xob tsawg
Khaws qhov kub ntawm qhov sib txawv<150°C
2. Tsis txhob kub kub
Tswj tus lej ferrite (FN 3-10 zoo tagnrho)
Siv cov hlau sib xyaw ua ke (ER316L)
3. Post Weld Cleaning
Pickling (nitric + hydrofluoric acid mix)
Passivation los kho Cr₂O₃ txheej
4. Zam Carbon Steel
Tsis txhob sib kis nrog cov cuab yeej carbon steel (sib tsoo lub log / hlau txhuam) kom tiv thaiv "dawb hlau" qhov chaw paug, uas ua rau xeb.

FAQ:
Q1: Tus nqi ntawm 316L flange nyob rau hauv 2026 yog dab tsi?
A: 316L flange tus nqi yog los ntawm$3.2 txog $8.5 per kg, nyob ntawm qhov loj, chav kawm, thiab hom.
Q2: 316L flange vs 304 flange, uas zoo dua?
A: 316L yog qhov zoo dua rau cov dej hiav txwv thiab tshuaj lom neeg ib puag ncig vim cov ntsiab lus molybdenum, thaum 304 haum rau kev siv dav dav.
Q3: Vim li cas 316L kim dua 304?
A: Vim tias nws muaj molybdenum thiab muaj kev tiv thaiv corrosion ntau dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride.
Q4: 316L flange puas siv tau rau hauv dej hiav txwv?
A: Yog, 316L feem ntau yog siv hauv cov dej hiav txwv, txawm hais tias super duplex nyiam rau cov xwm txheej huab cua.
Q5: Kuv puas tuaj yeem txuas 316L rau 304?
A: Yog lawm, tab sis qhov tshwm sim ntawm qhov sib koom ua ke tsuas yog zoo li corrosion-resistant raws li qib 304. Siv 316L muab tub lim los xyuas kom meej qhov vuam tseem muaj zog.
Q6: Thaum twg kuv yuav tsum xaiv Lap Joint vs Weld Neck 316L flange?
A: Siv Weld Neck rau siab -siab, piping tseem ceeb. Siv Lap Joint nkaus xwb yog tias cov kav dej yuav tsum tau nquag disassembly lossis teeb meem kev sib raug zoo tshwm sim thaum lub sijhawm teeb tsa.
Q7: Kuv yuav ua li cas tiv thaiv crevice corrosion nyob rau hauv 316L flange gasket?
A: Siv siab - zoo, tsis yog - cov khoom siv ntxeem tau (piv txwv li, PTFE lossis Graphite) thiab xyuas kom muaj lub zog bolt kom tshem tawm qhov khoob uas cov chloride ions tuaj yeem mloog zoo.
