Peb Qhov Zoo
1. High Corrosion Resistance
- Nrog tus nqi PREN ntawm kwv yees li 35, 2205 cov kav dej muaj qhov ua tau zoo heev rau chloride ion pitting thiab crevice corrosion. Lawv tuaj yeem tiv taus dej hiav txwv, tshuaj tsuag ntsev, thiab cov kua qaub los yog alkaline daws, ua rau lawv zoo tagnrho rau cov kav dej hauv cov cheeb tsam uas muaj corrosive, xws li marine engineering, tshuaj nroj tsuag, thiab kev kho dej khib nyiab.
- Peb cov kav dej Duplex 2205 tau dhau los ua cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ntsuas kev tiv thaiv corrosion kom ntseeg tau tias lawv cov corrosion kuj ua tau raws li ASTM A790 cov qauv.
2. Siab Dimensional raug
- Peb cov yeeb nkab raug xaiv tau raug tshuaj xyuas nruj, tshem tawm cov khoom siv raw nrog qhov sib txawv ntawm qhov sib txawv lossis qhov tsis sib xws. Thaum lub sijhawm tsim khoom, lawv tau tsim los siv cov txheej txheem kub extrusion thiab txias txheej txheem, ua raws li kev kho cua sov tom qab kos duab txias kom tsis txhob deformation.
- Peb cov kav dej tau txais kev ncaj ncees tom qab kev kho cua sov kom ntseeg tau tias qhov ncaj, thiab lawv tau soj ntsuam nruj me ntsis, nrog rau sab nraud txoj kab uas hla ntawm ± 0.05mm thiab phab ntsa thickness kam rau ua tsawg dua lossis sib npaug li 0.1mm.
3. Weldability thiab Machinability
- Peb Duplex 2205 Pipes undergo pickling thiab passivation los xyuas kom meej qhov chaw tsis muaj hlau paug thiab hnyav oxides, yooj yim vuam.
- Peb cov kav dej yog kev daws teeb meem- kho, ua rau muaj qhov sib xws ntawm microstructure thiab tsis muaj kev ntxhov siab seem. Tsis tas li ntawd, 2205 nthuav tawm ductility zoo heev, tso cai rau txias khoov, flaring, thiab lwm yam kev ua.
4. Kev Tswj Xyuas Zoo
- Txhua cov yeeb nkab uas tsim los ntawm TORICH raug kuaj xyuas cov cuab yeej cuab tam nruj, kev tshuaj xyuas qhov ntev, thiab tsis yog -kev sim ua kom puas tsuaj kom ua tau raws li cov qauv ASTM A790.
- Cov kav dej tau ntawv pov thawj los ntawm ISO 9001, PED, thiab TÜV, thiab txhua lub yeeb nkab muaj qhov sib txawv ntawm cov khoom siv hluav taws xob, batch tooj, thiab tube tooj, kom ntseeg tau tias tag nrho traceability los ntawm cov khoom tiav mus rau thawj steel billet.

FAQ
Q: Puas yog 2205 duplex steel yeeb nkab xav tau tom qab-weld kev kho cua sov?
A: Peb cov kav dej tau tswj xyuas nruj dua lawv cov tshuaj muaj pes tsawg leeg thiab raug xa mus rau hauv kev daws teeb meem -kho lub xeev. Feem ntau, tom qab- kev kho vuam tsis tas yuav tsum tau ua, txo qis lub sijhawm thiab cov nqi.
Q: Qhov siab tshaj plaws kev khiav hauj lwm kub yog dab tsi?
A: Duplex 2205 yog tsim rau cov ntawv thov hauv qab 300℃(570℃F). Kev siv tsis tu ncua nyob rau hauv ib puag ncig tshaj ~ 300℃yuav ua rau embrittlement.
Q: Cov xov xwm thiab kev ua haujlwm dab tsi yog 2205 cov kav dej haum rau?
A: Haum rau dej hiav txwv, ntsev tsuag, kua qaub thiab alkali daws, acidic gases uas muaj CO₂ / H₂S, pulp bleaching cawv, thiab lwm yam, dav siv hauv roj thiab roj, marine engineering, tshuaj, thiab kev tiv thaiv ib puag ncig; tsis haum rau muaj zog txo cov kua qaub xws li concentrated sulfuric acid thiab hydrochloric acid, kom tsis txhob muaj cov yeeb nkab corrosion.
