ASTM A335 P22 Yeeb Nkab Hauv Pob
ASTM A193 Qib B7 yog cov khoom siv cov khoom siv chromium rau lub zog hlau-molybdenum rau siab, siab siv tau, thiab cov ntaub ntawv tshwj xeeb. Qib B7 yog ib qho cua sov kho chromium molybdenum yuav tsum tau ntawm 100 ksi, muaj zog tsawg kawg ntawm 75 ksi thiab lub siab kawg ntawm 35 hrc. Lub ATTM A193 Cov Kev Siv Tshwj Xeeb Tshwj Xeeb rau Tshuaj Muaj Tshuaj, Cov Khoom Siv Txhua Yam, Hardness, Kev Kho Mob Cua Sov, thiab Pom zoo Cov Txiv Ntseej rau Chav B7 Rasteners. ASTM A193 Qib B7 yog qhov nthuav dav rau kev tawm tswv yim rau cov fasteners, feem ntau pom nyob hauv bolts lossis kav dej, li qub, flanges thiab fittings.

Cov txhuas alloy muaj cov yam ntxwv hauv qab no: 1. Nws muaj cov tshuaj zoo corrosion tsis kam rau feem ntau cov tshuaj corrosive hauv qab ob qho kev mob ntawm cov pa oxidation thiab kho. Úit muaj kev tsis kam zoo rau pitting corrosion, void corrosion thiab intergranular corrosion. Cov ntsiab lus ntau dua ntawm MO thiab CR ua rau aluminium alloy resistant rau corrosion los ntawm corrosion los ntawm corroside ion cov ntsiab lus, thiab cov w sij hawm ntxiv txhim kho cov corrosion tsis kam. Nyob rau tib lub sijhawm, haastelloy c-276 aluminium alloy yog ib qho ntawm cov khoom raw ntub uas tiv thaiv cov chlorine ntub, hypochlorite thiab chlorine dioxide solutions. Ester daws tau pom meej corrosion tsis kam. Nws yog ib qho ntawm ob peb cov khoom siv raw uas tuaj yeem siv ua qhov kub sulfuric acid noo noo.
Peb tus TI Qib 2 Flange, Carbon Steel A694 F60 F65 (TTM ARB, ASTM A182 S32750 Stad Bolt yog qhov tshiab hauv thev naus laus zis thiab tsim nyog hauv cov qauv. Lawv muag tau zoo nyob hauv tsev thiab txawv tebchaws thiab tau txais tos los ntawm cov neeg siv feem ntau. Los ntawm kev ua haujlwm zoo, peb vam tias yuav ua rau muaj kev loj hlob ua kom muaj kev loj hlob ntawm kev tswj hwm ib puag ncig thiab qhov tseem ceeb ntawm cov muaj zog tib neeg cov peev txheej. Tam sim no, peb tab tom siv zog ntxiv rau hauv qhov tshiab ib txwm, cia siab tsim kho tus qauv tshiab ntawm lub tuam txhab kev txhim kho hauv kev coj tshiab. Thaum nkag siab cov ntsiab lus tseem ceeb ntawm kev siv tshuab, lub tuam txhab them ntau dua los muab cov khoom lag luam thiab cov kev pabcuam zoo dua. Cov cuab yeej siv tau zoo heev, cov txuj ci kws tshaj lij, cov kev pab ntau lawm, kev lees paub zoo thiab raws sijhawm tau peb cov neeg siv khoom.
Kev tsim cov kev tsim ua kom ASME SA182 F9 flanges yuav ua tiav siv cov alloys nrog cov ntsiab lus muaj roj carbon ntau. Txo cov ntsiab lus carbon hauv cov alloys txo qhov tsim ntawm carbide precipitates. Qhov no txhais tau tias Alloy Steel F9 Flanges yuav tsis muaj kev cuam tshuam rau kev txhim kho kev txhim kho hauv cov cua sov cuam tshuam weld cheeb tsam.
International Stainless Hlau Txawv Txawv Txoj Cai Lub Tebchaws Asmeskas Hlau thiab Hlau Lub Koom Haum Siv Peb Tus lej los cim ntau cov qauv ntawm cov kab mob stainless. Ntawm lawv: ¢ atausustenitic stainless hlau yog cim nrog 200 thiab 300 series cov lej. For example, some of the more common austenitic stainless steels are marked with 302, 304, 316 and 310, ¢ÚFerritic and martensitic stainless steels are used The number of the 400 series is represented. ¢ferritic stainless hlau yog cim nrog 430 thiab 446, cov xim tawv tawv me me), muaj nag lossis 4%
Fasteners ua los ntawm no antenenitic steel hlau yuav tsum tau kho cov kev kho mob carbide ntawm cov bar kom kho kev kho mob tom qab lub taub hau kev ua haujlwm ntawm bolts nrog forged taub hau.
Peb Alloy Hlau ASTM ATTM AN182 F5 Weld-caj dab flanges tau muab los pab, thiab lwm yam tshuaj tua hluav taws, phaj flanges, tso tawm flanges, txo cov flanges thiab ntau ntxiv. Cov flanges no tau siv dav hauv kev lag luam hluav taws xob, kev lag luam roj av, kev lag luam tshav kub kub, roj av drilling cov tuam txhab thiab ntau ntxiv.
Tsau-nthuav dav iav-encapsulated girapsulated alloys, muaj ib qho kev nthuav dav thermal, muaj ib lub khob hluav taws xob nthuav dav zoo ib yam li qhov ntsuas kub
