Cia peb pib nrog qhov tseeb:
Austenitic stainless hlau kav yog ib txwm siv nyob rau hauv ntau yam ntawm kev xeb ib puag ncig. Txawm li cas los xij, yog tias koj xyuam xim, koj yuav pom tias hauv cov qauv tsim ntawm qee cov chav nyob, tsuav ntawm DN≤400, txhua yam ntawm cov ntaub ntawv yog cia li tau txais. Hauv cov qauv tsim ntawm lwm cov chav nyob, tsis muaj teeb meem li cas cov caliber ntau me me yog li cas, lawv kuj siv pob tw-welded yeeb nkab fittings es tsis txhob tub raj.
Raws li cov lus hais mus: txhawm rau kom ntseeg tau qhov zoo ntawm cov vuam me me thiab tsis txhob siv vuam txuas ntxiv,, cov kev sib txuas yog feem ntau siv es tsis txhob sib txuas. Yog li, yog vim li cas lwm yam units ntawm stainless hlau me me caliber pipes tsis bear intubation? Qhov no cuam tshuam nrog teeb meem: kev ua kom xeb.
Cia peb tham txog dab tsi yog crevice corrosion?
Thaum muaj qhov sib txawv (feem ntau 0.025-0.1mm) nyob rau saum npoo ntawm cov hlau uas muaj kev sib cav sib ceg, uas ua rau cov hlau corrosion, hu ua gap corrosion. Crevice corrosion feem ntau ua qhov tsis zoo ntawm lwm txoj kev xeb (xws li pitting corrosion, yog li txoj haujlwm kev ntxhov siab kom tsis txhob muaj tshwm sim ntawm kev ua xeb corrosion. Lub hav zoov ntawm cov kab nrib pleb yuav tsum zam rau kev tsim qauv ntawm cov raj xa hluav taws xob rau qhov nruab nrab uas yog nquag los tsoo xeb corrosion.
Stainless hlau 304 Flange
Nws yog vim muaj qhov sib txawv hauv lub qhov kev sib txuas, yog li cov khoom siv hauv corrosion, rau lub hav zoov ntawm kev sib txuas hlau, rau cov txheej txheem vuam tswj kom paub tseeb, zam kev ua tau zoo, zam kev siv cov interubation.
304 yog lub hlau stainless hlau, nws yog dav siv nyob rau hauv kev tsim cov cuab yeej siv thiab qhov uas yuav tsum tau ua zoo ua haujlwm (corrosion tsis kam thiab muaj peev xwm).
304 Stainless hlau yog ib hom ntawm stainless hlau tsim raws li Astm cov qauv hauv Tebchaws Meskas. 304 yog sib npaug rau Tuam Tshoj tus 0cr19NI9 (0cr18ni9) stainless hlau. 304 muaj 194 muaj 19% chromium thiab 9% npib tsib xee.
304 yog cov hlau dav dav hlau hlau, kub tiv taus cov hlau. Siv hauv cov khoom noj ntau lawm, xitong tshuaj chetter, lub zog nuclear, thiab lwm yam.
304 Stainless Hlau Taub Qab Vuam FlangeYog cov chromium siv dav siv chromium - Npib Stainless hlau, nrog zoo corrosion tsis kam, tshav kub ua kom tau, tsawg kub zog thiab cov khoom siv tshuab. Corrosion tsis kam nyob rau hauv cov huab cua, yog tias nws yog thaj chaw muaj cua lossis huab cua tsis zoo, nws yuav tsum tau ntxuav kom tsis txhob xeb. Haum rau kev ua zaub mov noj, khaws thiab tsheb thauj mus los. Nws muaj zoo machinability thiab weldability. Phaj Kub Exchange, rab phom, khoom siv hauv tsev, cov khoom siv tsev, tshuaj, kev lag luam tshuaj, thiab lwm yam.
