ASTM A790 UNSIVE S32750 Seamless Sup Hmoo Stainless Hlau Rau Dej Kho
ASTM A790 unam s32750 Seamless yeeb nkab muaj cov yeeb nkab zoo heev, muaj zog nyob rau hauv chloride thiab detable ib puag ncig, ua rau txoj kev xaiv zoo tshaj plaws rau kev kho dej. Nws ua tau zoo heev rau pitting thiab kev nyuaj siab corrosion tawg ua nws haum rau kev siv xws li kev tiv thaiv hluav taws xob, thiab kev tswj hluav taws kub.
Dab tsi yog ASTM A790 S32750 cov khoom siv?
ASTM A790 UNSIVE S32750 PIG RAU LUB SUPER -} ruplex stainless hlau qeb. Vim tias nws cov txiaj ntsig lub zog yog ob zaug ntawm Austenitic Stainless hlau, nws tuaj yeem siv los tsim thawjLee cov yeeb nkab. Nws microstructure yog 50% ferrite thiab 50% austenite.
ASTM A790 S32750 yog qhov tshwj xeeb rau seamless super - cov yeeb nkab steel. Super - cov hlau yog ib hom stainless hlau yog ib hom khoom stainless muaj zog thiab corrosion tsis kam dua li cov khub duplex steels. Super - teb seamless yeeb nkab xws li roj thiab roj ua rau nws cov khoom siv corrosion thiab corrosion tsis kam nyob rau hauv ib puag ncig hnyav. Qhov kev tsim kho ntawm cov kav dej no ua kom muaj qhov du, cov ris tsho tsis zoo, nrog rau kev ua kom muaj zog thiab lub zog siab. Lawv feem ntau muaj nyob rau ntau qhov ntau thiab tsawg thiab thicknesses kom tau raws li cov kev cai tshwj xeeb ntawm cov ntawv thov sib txawv.

Khoom Siv Dej
Desalination Nroj Tsuag: nws cov chloride tsis muaj nqi yog qhov tseem ceeb rau cov khoom siv desalination.
Wastewater kev kho mob: nws lub peev xwm los lis cov tshuaj corrosive thiab dej khib nyiab ua rau nws haum rau kev tswj kom tsis muaj pov haum.
Kev Tiv Thaiv Hluav Taws Kub: Siv hauv cov khoom siv hluav taws kub thiab cov roj hmab.
Cov dej tso dej ruaj ruaj: siv cov tshuab tso dej: siv cov tshuab uas yuav tsum muaj siab - lub zog, corrosion {1} {reassant piping.
Cov tshuab hluav taws xob kub thiab cov hnab looj: cov tshuaj no feem ntau siv rau cov chaw ua pa hluav taws xob hauv cov chaw lim dej.
