ASTM A790 / A790M yog cov txheej txheem thoob ntiaj teb kev qhia tshwj xeeb rauseamless thiab welded ferritic / austenitic stainless hlau yeeb nkabnpaj rau kev pabcuam corrosive. Feem ntau hu uaDuplex Stainless hlau, cov kav dej no tau tsim kho kom xa cov kev ua tau zoo tshaj plaws hauv kev xav tau kev lag luam ib puag ncig.
Tus qauv muab qhov tshwj xeeb rautiv thaiv kev nyuaj siab corrosion cracking, ua rau nws yog qhov kev xaiv zoo rau cov ntawv thov uas tus qauv austenitic steels (xws li 304 lossis 316) yuav ua tsis tiav.
Cov yam ntxwv tseem ceeb ntawm ASTM A790
Khoom siv:Ferritic / Austenitic (Duplex) Stainless hlau.
Yam khoom:Seamless thiab Welded Yeeb Nkab (feem ntau loj diameters dua tubing).
Core Advantage:Ua ke lub zog siab (kwv yees . 2x tawm lub zog ntawm 304/316) nrog kev ua haujlwm zoo heev rau chloride kev ntxhov siab corrosion tawg.
Hom Qib:Xws li UNS S31803, S32205, S32750 (2507), S32760 (Zeron 100), thiab lwm yam.
Tej kev siv
ASTM A790 piping yog qhov tseem ceeb rau kev lag luam uas yuav tsum tau muaj zog, ruaj khov infrastructure:
Roj & Roj:Offshore platforms, ntws kab, thiab risers.
Kev ua tshuaj lom neeg:Thauj aggressive acids thiab cov kuab tshuaj.
Tubrog nkoj:Seawater cooling systems thiab desalination nroj tsuag.
Pollution Control:Flue gas desulfurization systems.
Vim li cas thiaj xaiv ASTM A790?
Cov txheej txheem no tswj hwm nruj cov tshuaj muaj pes tsawg leeg txwv thiab cov cuab yeej cuab tam kom ntseeg tau tias muaj kev nyab xeeb thiab siv tau ntev. Tag nrho cov kav dej yuav tsum tau ua kom sov-kho (kev daws teeb meem) thiab dhau qhov ntsuas hluav taws xob hydrostatic lossis tsis muaj kev puas tsuaj.
