Khoom Parameters
Alloy 20 Tube
Khoom siv
Alloy 20, tseem hu ua Carpenter 20, yog npib tsib xee - hlau-chromium austenitic alloy tsim rau siab tshaj plaws tiv thaiv acid nres, tshwj xeeb sulfuric acid. Nws yog cov khoom siv ntau yam uas muaj kev tiv thaiv zoo heev rau pitting thiab crevice corrosion nyob rau hauv cov tshuaj ib puag ncig uas muaj chlorides thiab sulfuric acid. Alloy 20 feem ntau raug xaiv rau nws lub peev xwm los tiv thaiv kev ntxhov siab corrosion tawg thiab nws cov khoom zoo tshaj plaws.
Specification
Alloy 20 cov kav dej yog tsim raws li ntau yam kev cai thoob ntiaj teb, suav nrog ASTM B729, ASME SB729, thiab DIN 17751. Cov qauv no xyuas kom meej tias cov kav dej tau raws li cov khoom siv kho tshuab thiab tshuaj lom neeg, ua kom lawv haum rau kev thov.
Ntsiab nta
Corrosion Resistance: Alloy 20 nthuav tawm ua haujlwm zoo heev rau sulfuric acid, ua rau nws zoo tagnrho rau kev siv tshuaj lom neeg ua haujlwm.
Pitting thiab Crevice Corrosion: Cov alloy muaj pes tsawg leeg muab kev tiv thaiv zoo rau pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride - nplua nuj ib puag ncig.
Kev nyuaj siab Corrosion Cracking: Alloy 20 yog resistant rau kev ntxhov siab corrosion cracking, ib qho teeb meem tshwm sim nyob rau hauv ib puag ncig aggressive tshuaj.
Weldability: Cov hlau tuaj yeem welded siv cov txheej txheem vuam, ua kom muaj ntau yam rau ntau yam txheej txheem fabrication.
Durability: Nrog nws cov khoom siv kho tshuab muaj zog, Alloy 20 cov kav dej yog qhov ruaj khov thiab txhim khu kev ntseeg tau ntev - siv rau hauv cov xwm txheej hnyav.

Qib Steel
Alloy 20 yog cais raws li UNS N08020 kev xaiv. Nws yog high-kev ua tau zoo alloy uas sib txuas cov khoom ntawm npib tsib xee, chromium, thiab molybdenum los muab kev tiv thaiv tshwj xeeb rau ntau qhov chaw corrosive. Qhov sib ntxiv ntawm tooj liab txhim kho nws txoj kev tiv thaiv rau sulfuric acid, ua rau nws nyiam xaiv rau kev siv tshuaj lom neeg.
Daim ntawv thov
Alloy 20 kav yog siv dav hauv kev lag luam xws li:
Kev ua tshuaj lom neeg: Rau tuav sulfuric acid thiab lwm yam tshuaj lom neeg.
Petrochemical: Nyob rau hauv ib puag ncig uas yuav tsum tau tiv thaiv chlorides thiab sulfuric acid.
Tshuaj: Rau cov khoom siv thiab cov kav dej uas yuav tsum tau muaj kev tiv thaiv corrosion.
Khoom noj khoom haus thiab dej haus: Hauv cov txheej txheem uas muaj cov tshuaj acidic.
Cov qhab nia xaiv tau
Thaum Alloy 20 muaj txiaj ntsig zoo, lwm cov ntaub ntawv yuav raug txiav txim siab nyob ntawm cov kev thov tshwj xeeb:
Hastelloy C276: Muaj kev tiv thaiv zoo tshaj plaws rau ntau qhov chaw corrosive.
Ib 625: Paub txog nws lub zog siab thiab ua haujlwm rau oxidation thiab corrosion.
316L Stainless hlau: Tus nqi ntau dua - kev xaiv zoo nrog corrosion kuj zoo, txawm tias tsis zoo li Alloy 20 nyob rau hauv ib puag ncig sulfuric acid.
