Yog li, cov raj xa hluav taws xob yuav tsum tsim qauv thiab tsim nyob rau hauv ib txoj kev uas tuaj yeem ua rau cov kev nyuaj siab rau thaum lub sijhawm ua kua lossis tshuaj lom neeg. Qee lub chaw (cov nroj tsuag hluav taws xob, cov roj av ntxiv, thiab lwm yam) yuav tsum tau siv hluav taws xob ntev thiab nyhav ntxig. Ntxiv mus, cov chaw ntawm cov teeb meem siv teeb meem vim yog qhov chaw ua haujlwm tsawg.

Lwm yam nrov npe npib npe nrov-chromium alloys muaj hnub nyoog tawv los ntawm kev ntxiv ntawm txhuas thiab titanium.

Raug corrosion corrosion nrog rau cov khoom siv titanium dioxide (Chloride txoj kev), perchlorethylene synthes, viscyl chloride monomer (VCM), thiab magnesium chloride.

316L kuj yog tus qauv zoo kawg rau kev kub siab, kev siv ntau xeb, uas yog vim li cas nws thiaj nrov rau kev siv hauv kev tsim kho thiab marine ua haujlwm.

Cov leeg cov kab pheebsuab feem ntau yog siv rau hauv pob zeb ua qauv kom paub tseeb tias cov fittings kom ntseeg tau tias yog qhov chaw ua ntej pouring pob zeb ua ntej.

Tsuas yog raws li lub npe ¡° ua ntej engineered à ° qhia, cov no yog engineered ntawm lub Hoobkas thiab tau sib sau ua ke ntawm qhov chaw.

Lub alloy 800 series (Incoloy 800, 800H thiab 800HT) yog siv tshuaj lom neeg lub zog ntawm Nickidation, carburization thiab lwm hom kev mob siab corrosion. Alloy 800 (tsis yog N08800), Alloy 800h (tsis yog N08810) thiab Alloy 800HT (0.85 rau 1.2%) kom paub meej cov kev ua tau zoo tshaj plaws.

Cov kav dej nyoos raug txiav rau cov uas yuav tsum tau loj thiab cov txav nrog cov yeeb nkab fittings rau lub rooj haum, qhov twg qee qhov sib txuas ua ke (i.e. txuas ib ntus). Lub txiaj ntsig sub-sib dhos (ib feem ntawm qhov kawg cov kab ua ntej cov zaub mov) txuas ntxiv nrog cov chaw sib txuas) ua ntej nws rov qab mus rau lub rooj sib npaug thiab tau ua kom haum nrog lwm cov kab noj mov.

Hastelloy B2 yog npib tsiboly-molybdenum alloy tshwj xeeb tshaj yog haum rau kev tuav cov khoom siv uas txo cov khoom siv tshuaj uas txo ib puag ncig tshuaj. Xws li kev siv hauv kev ua lag luam ua lag luam muaj feem xyuam xws li sulfuric acid, phosphoric acid, hydrochloric acid, hydrothoric acid, acceletic acid thiab acictic acid thiab acetic acid.

Thaum nyob rau hauv lub hnub nyoog-hardened mob, monel k-500 muaj qhov kev ntxhov siab ntau dua li monel 400. Alloy 400. Alloy lub zog thaum piv nrog alloy 400.

Lub teeb tsom iav steel framing yog qhov tseem ceeb ntawm kev tsim kho yog qhov muaj zog, tsis muaj tseeb, pub tau zoo ua pov thawj nyob rau hauv ntau cov ntawv thov.

Tus naj npawb ntawm Welds nyob rau ib qho spool yuav tsum tau khaws cia hauv qhov tsawg kawg nkaus suav. Qhov ntev ntawm cov spacing ntawm Welds muaj kev cai lij choj siv thiab cov kab nruab nrab yuav tsum tsis txhob loj dua plaub zaug ntawm cov yeeb nkab tuab ntawm cov yeeb nkab lossis haum. Tom qab MSDS tseem ceeb, Tacks Welds yuav tsum ua kom meej meej. Txhua yam vels hauv cov spools yuav tsum tau muab siv raws li kev tsim kho vuam cov txheej txheem specification Specification (WPS). Tom qab cov txheej txheem vuam ua tiav, kev tswjhwm zoo ntawm cov cheebtsam yog ua los ntawm cov kws tshaj lij.

Inconel 718 2.4668 Cov yeeb nkab steel hlau "hlau yeeb nkab ua kom tsis taus zoo rau corrosion

Hastelloy B3 Ua kom muaj cov khoom siv yeeb nkab spools nrog kev tiv thaiv zoo heev rau kev cuam tshuam corrosion

Yeeb nkab spool yog cov khoom lag luam ua ntej ntawm cov pas dej piping. Cov kav dej, flanges, thiab fittings yog hu ua cov kab hlais thiab lawv tsim ua ntej lawv siv hauv cov kab ke piping.

Lub alloy muaj peev xwm muaj peev xwm seem thiab tswj nws cov qauv AuTenitic. Incoloy 800 feem ntau siv hauv kev siv nrog kub txog 1100¡u yog ib txwm siv nyob rau hauv qhov chaw txias saum toj no 1100¡u f qhov twg nkag mus rau qhov taub thiab qhov tsis sib xws.

Lub qhov (socket) welded Tees kuj ua ib co hlua ntawm cov kab sib txuas. Lawv siv rau cov ntawv thov siab. Nyob rau hauv kev tawm tsam rau lub taub qab welded tees welded tees yog siv hauv cov ntawv thov uas lub vojvoog ntawm cov kav dej feem ntau me dua. Qhov (socket) welded Tees tsis tas yuav muaj lub beveling txheej txheem ua ntej vuam. Yog li no, cov tees zoo no yog qhov txaus siab nyob rau hauv qee cov ntawv thov uas cov ceg kawg yuav tsum tau khaws cia ua ntej thiab tom qab vuam.
