Duplex Steel Kos Valve: Qhov kawg qhia rau siab - kev ua yeeb yam, corrosion {1} {Resistant li qub

Cov lus piav qhia meta:Tshawb nrhiav cov txiaj ntsig ntawm lub duplex steel kos valve. Cov kws tshaj lij cov kws tshaj lij kev tawm tsam nws corrosion tsis kam, siab lub zog, kev siv hauv roj & roj av, thiab vim li cas nws zoo dua rau cov qauv stainless hlau. Kawm txog hom hom nyiam dual phaj wafer.

Lub hauv paus rau phau ntawv

A DUPLEX Steel Kos ValveYog ib qho tseem ceeb ntws tswj cov tshuaj tivthaiv tswj tsim rau cov ntawv thov xav tau tshaj plaws. Nws muab cov kev zam tshwj xeebCorrosion Kujntawm stainless hlau nrogMuab ob npaug rau cov txiaj ntsig lub zog, Ua rau nws xaiv qhov zoo tshaj plaws rau kev tiv thaiv cov neeg khiav rov qab hauv cov tshuab tuav cov corrosive kev tshaj tawm, siab siab, thiab chlorides. Tsis zoo li cov qauv 316 stainless hlau li qub, ib qho kos valve ua los ntawm ob tus qauv steel (xws li unsplex steel (xws li unparalleled daievity thiab kev cia siab, txo cov nqi kho, txo cov nqi kho mob thiab downtime.

Vim li cas thiaj xaiv lub Duplex Steel Kos Valve? Tus yuam sij

Cov khoom zoo tshaj ntawm cov yas steplex stainless ncaj qha txhais rau hauv cov txiaj ntsig tseem ceeb rau kev kuaj xyuas:

Tshwj kev txiav txim siab corrosion:Thawj qhov laj thawj rau xaiv cov hlau duplex. Nws muaj kev tiv thaiv zoo heev rau:

Pitting thiab crevice corrosion:Ua tsaug rau cov chromium siab (CR), Molybdenum (MO), thiab nitrogen (n) cov ntsiab lus. Nws siabPitting tiv thaiv tus naj npawb (Pren> 34)deb tshaj li ntawm 316L stainless hlau.

Kev ntxhov siab corrosion cracking (SCC):Ib hom tseem ceeb tsis ua hauj lwm rau cov qauv stainless hlau hauv chloride - kev nplua nuj ib puag ncig. Duplex steel yog cov tiv taus zoo, ua rau nws zoo meej rau ntug dej hiav txwv thiab marine.

Yaig - corrosion:Lub zog siab thiab lub microstructure muab cov kev tiv thaiv zoo heev rau cov kua txiv ntoo thiab ua kom haum.

Siab zog thiab lub teeb tsim heev:Nrog apaib lub zog kwv yees li ob zaug ntawm tus qauv ustenitic steels(piv txwv li, 304/316), cov hlau dua tso cai rau lub cev thate thiab disc. Qhov kev tshwm sim no ua rau lub teeb ntais nrawm dua {5} Qhov hnyav hnyav, ua rau cov nqi thauj khoom, qis dua cov kev pab tsiaj ntawv.

Tus nqi zoo heev - ua tau zoo:Thaum lub sijhawm thawj cov khoom siv thawj zaug yog siab dua 316L, tag nrho lub neej lub neej feem ntau yog qis dua. Nws lub zog zoo tshaj tawm rau kev tsim qauv ntau dua, thiab nws cov yeeb yam zoo tshaj plaws tiv thaiv kev ua haujlwm lub neej, kev hloov kho kom tsawg dua thiab kev them nyiaj kho tshiab. Nws feem ntau ua tus nqi -}}}} Xaiv lwm txoj kev xaiv kom kim dua nickel {}} beed alloys.

Zoo weldability:Duplex Steel Xyuas Li qub tuaj yeem tau yooj yim ua ke siv cov txheej txheem vuam, kom muaj zog, corrosion {{}} tiv taus cov pob qij txha.
