Taw qhia rau ASTM A789 Txuj
ASTM A789 yog dab tsi?
ASTM A789 / A789M yog cov txheej txheem thoob ntiaj teb kev qhia npogseamless thiab welded ferritic / austenitic stainless hlau tubingrau kev pabcuam dav dav. Cov khoom no yog dav hu uaDuplex Stainless Hlau.
Cov txheej txheem tshwj xeeb yog tsim los rau cov ntawv thov uas xav tau kev tiv thaiv corrosion zoo dua, nrog rau qhov tshwj xeeb rau kev ua haujlwmkev nyuaj siab corrosion cracking, ua rau nws zoo tagnrho rau hnyav industrial ib puag ncig.
Cov yam ntxwv tseem ceeb ntawm ASTM A789
Hom khoom: Ferritic / Austenitic (Duplex) Stainless hlau.
Daim ntawv khoom: Seamless thiab Welded Tubing.
Core Advantage: Muab lub zog ntau dua thiab ua haujlwm zoo dua rau chloride kev nyuaj siab corrosion piv rau cov qauv austenitic steels (xws li, 304/316).
Cov Qib Siab: suav nrog UNS S31803, S32205, S32304, S32750, thiab lwm yam.
Tej kev siv
ASTM A789 tubing yog qhov tseem ceeb hauv kev lag luam uas xav tau kev ua haujlwm siab thiab corrosion kuj:
Tshuaj & Petrochemical: Thawv corrosive media.
Marine & Offshore: Seawater txias tshuab thiab platforms.
Fais fab & Ib puag ncig: Kub exchangers thiab flue gas desulfurization.
Roj & Roj: Siab -siab thiab corrosion- cov kav dej tiv taus.
Vim li cas thiaj xaiv ASTM A789?
Tus txheej txheem tswj hwm nruj tshuaj muaj pes tsawg leeg (Cr, Ni, Mo, N) thiab cov khoom siv cuab yeej cuab tam. Tag nrho cov raj yog cua sov-kho thiab yuav tsum xeem dhau hydrostatic los yog tsis muaj hluav taws xob kuaj kom muaj kev nyab xeeb thiab kev ntseeg siab nyob rau hauv siab thiab kub.
