Peb Qhov Zoo
1. Corrosion Resistance
- Peb cov ASTM A928 UNS S32750 steel yeeb nkab muaj kev tiv thaiv corrosion zoo heev, nrog rau PREN ntsuam xyuas ntawm ntau dua lossis sib npaug li 40. Nws raug siv tshuaj tsuag ntsev thiab tshuaj tiv thaiv intergranular, kom ntseeg tau tias nws tsim nyog rau kev siv dej hiav txwv, brine, thiab cov txheej txheem tshuaj lom neeg.
- Cov kav dej tau raug txheeb xyuas los ntawm kev xeem passivation kom paub meej tias cov yeeb yaj kiab ua tiav ntawm cov yeeb nkab saum npoo, txhim kho lawv cov kev tiv thaiv corrosion.
2. Siab zog
- UNS S32750 boasts lub zog tawm los ze li ob npaug ntawm austenitic stainless hlau xws li 316L, tso cai rau txo phab ntsa thickness thaum tuav lub zog. Qhov no ua rau nws zoo tagnrho rau siab -siab thiab cov qauv siv uas muaj phab ntsa tuab heev yog ib qho kev txhawj xeeb.
- Cov khoom peb siv yog kuaj los ntawm spectrometer los xyuas kom meej raws li ASTM A928 tus qauv specifications; flattening thiab flaring xeem yog ua los xyuas kom meej lub siab tsis kam ntawm welded kav hauv boiler systems.
3. Siab Dimensional raug
- Peb cov ASTM A928 UNS S32750 steel yeeb nkab yog tsim los siv lub computer -tswj yob- cov cuab yeej tsim los ua kom zoo ib yam ntawm txoj kab uas hla thiab roundness ua ntej vuam. Tom qab vuam, cov yeeb nkab yog qhov loj thiab calibrated nrog chais kom ua tiav qhov xav tau sab nraud thiab phab ntsa tuab nrog qhov sib txawv me me.
- Cov kav dej tau txais kev soj ntsuam nruj me ntsis, txo qhov kev xav tau ntawm kev ua haujlwm thib ob thiab ua kom muaj kev sib raug zoo nrog cov kav dej, flanges, thiab cov kav dej hauv qab dej hiav txwv.
4. Kev kho deg
- Peb cov yeeb nkab tau siv tshuaj annealing thiab pickling los txhim kho corrosion kuj. Cov yeeb nkab yog polished rau qhov chaw du, thiab sandblasting thiab kev cai tiav yog muaj.
- Rau siab -purity applications, electropolishing yog muaj, xws li rau siab - purity tshuaj, desalination, los yog offshore daim ntaub ntawv.
thaj chaw thov
- Kev lag luam roj thiab roj: Offshore platforms thiab subsea pipelines, kis kab.
- Kev ua tshuaj lom neeg: Kub exchangers thiab evaporators, piping rau acid rov qab, urea nroj tsuag, thiab refineries.
- Lub zog tiam: Flue gas purification systems, condensers exposed to seawater, and water feed systems.
- Desalination: Seawater inlet and outlet pipelines, heat exchanger and evaporator tubes, brine concentrate thiab permeate piping.
- Kev lag luam marine: Nkoj tso pa system, hull thiab lawj fittings.

FAQ
Q: ASTM A928 UNS S32750 yeeb nkab siv rau dab tsi?
A: UNS S32750 muaj lub zog siab thiab corrosion kuj thiab feem ntau yog siv rau hauv cov corrosive siab thiab siab - ib puag ncig siab, xws li offshore roj thiab roj, desalination nroj tsuag, tshuaj ua, tshav kub exchangers, thiab seawater systems.
Q: UNS S32750 piv rau UNS S32205 (2205) li cas?
A: UNS S32750 (2507) muaj lub zog siab dua thiab muaj zog corrosion kuj zoo dua UNS S32205 (2205), tshwj xeeb tshaj yog nyob rau hauv siab -chloride thiab seawater ib puag ncig. Nws yog qhov tsim nyog rau kev xav tau kev ua haujlwm.
Q: S32750 puas tuaj yeem tiv taus qhov kub siab thiab kub kub hauv kev ua haujlwm sab nrauv?
A: Yog. Nws lub zog tawm los yog yuav luag ob npaug ntawm tus qauv austenitic stainless hlau, thiab nws tswj tau zoo heev corrosion kuj nyob rau hauv chloride - muaj cov xov xwm, txawm nyob rau ntawm qhov kub txog li 300℃(572℃F).
