B729 Uns N08020 Duplex 2205 Tube

Peb cov khoom muaj nyob rau hauv ASTM B729 UNS N08020 thiab ASTM A790 2205 qib. UNS N08020, tseem hu ua Alloy 20, yog npib tsib xee - hlau-chromium austenitic stainless hlau alloy tsim rau siab tshaj plaws tiv thaiv sulfuric acid nres. Nws muaj kev tiv thaiv zoo heev rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion cracking nyob rau hauv cov tshuaj lom neeg nruj heev. Duplex 2205 yog ib qho ferritic{11}}austenitic stainless hlau uas ua ke nrog lub zog siab nrog kev ua haujlwm zoo heev rau chloride kev nyuaj siab corrosion tawg thiab pitting. Nws lub zog tawm los yog kwv yees li ob npaug ntawm cov pa austenitic stainless hlau thiab yog siv dav hauv marine thiab offshore daim ntaub ntawv.

Khoom Description

B729 Uns N08020 A790 Duplex 2205 Tube

Qhov zoo ntawm B729 Uns N08020 A790 Duplex 2205 Tube

ASTM B729 UNS N08020 Cov Lus Qhia Tshwj Xeeb(Alloy 20): Tsim los rau acidic ib puag ncig (tshwj xeeb tshaj yog sulfuric acid), nws yog qhov kev xaiv thaum qaub corrosion kuj tseem ceeb tshaj qhov muaj zog txhua yam. Nws yog dav siv nyob rau hauv tshuaj thiab petrochemical cov nroj tsuag, reactors, tshav kub exchangers, cia tank, thiab piping systems raug rau cov acids muaj zog.
ASTM A790 Duplex 2205(S32205/S31803): Tsim los rau chloride- thaj chaw nplua nuj (xws li dej hiav txwv, brine, thiab cov kua dej ua haujlwm), nws yog qhov kev xaiv thaum muaj zog thiab tsis kam rau cov tshuaj chloride-yuav tsum tau muaj kev ntxhov siab corrosion cracking. Nws yog siv nyob rau hauv offshore roj thiab roj, desalination, marine engineering, pulp thiab ntawv, thiab structural piping.

Daim ntawv thov ntawm B729 Uns N08020 A790 Duplex 2205 Tube
