Zhengzhou Huitong Pipeline Equipment Co., Ltd.

Cov kab phuav cov quav yog ua ntej pov tseg kom txo cov nqi teb constalls thiab muab cov khoom lag luam zoo dua hauv cov khoom. Lawv feem ntau flanged kom tau txais kev sib txuas rau lwm cov kab. Lub spool fabrication ib txwm ua los ntawm cov tuam txhab tshwj xeeb muaj cov cuab yeej siv tau.

Inconel 600 Cov Kab Yeeb Nkab nrog cov neeg tuaj yeem ua rau cov neeg Sulphur cov tebchaw thiab ntau cov oxidizing ib puag ncig

Qhov no cov hlau stainless yeeb nkab feem ntau flanged los pab txhawb kev sib txuas nrog lwm cov kev lag luam xws li cov khoom siv hluav taws xob zoo li yuav tsum muaj cov piping nthuav dav.

Nws muaj qhov ua tau zoo heev rau intergranular corrosion tom qab kis tau kub hauv cov chromium carbide nag los nag (400 ¨c 816¡Ãc).?

Cov qib no tau nce nws cov qauv qub thiab sib tshooj ua pov thawj pab tau lwm cov ntawv thov, uas tso cai rau cov khoom siv uas muaj kev zam rau hauv ntau yam li cov khoom siv

Rau qee daim ntawv thov, qib 254 smo tau tshaj tawm tias yuav raug nqi them tus nqi rau cov npib tsib xee thiab titanium alloys.

304 Stainless hlau yog daim ntawv feem ntau ntawm cov hlau stainless hauv ntiaj teb vim nws zoo heev corrosion thiab tus nqi. Nws muaj 16% rau 24% chromium chromium thiab txog 35% npib tsib xee, ntxiv rau cov pa roj carbon thiab manganese.

Chromium yog tus thawj coj tus neeg sawv cev rau kev sib tham corrosion tsis kam nyob hauv nruab nrab nruab nrab lossis oxidizing ib puag ncig.

Chromium, molybdenum thiab nitrogen nce kev tawm tsam rau pitting corrosion. Npib tsib xee ua cov qauv Austenic.

Qhov no npib tsib xee xwb tshwj xeeb yog tiv thaiv hydrochloric thiab hydrofluoric acids thaum lawv de-aerated. Raws li tau xav tau los ntawm nws cov ntsiab lus tooj liab, alloy 400 yog tau tawm tsam sai heev los ntawm nitric acid thiab ammonia systems.

Hastelloy B-2 yog npib tsib xee tau wrought alloy nrog zoo heev tiv taus rau hydrochloric acid ntawm txhua qhov siab thiab kub.

Nyob rau hauv kev hloov oxidizing thiab txo cov mob uas muaj kev txom nyem los ntawm cov xidationo.

Rau cov khoom ntawm cov dej thiab cov roj av nrog, cov kav hlau steel yog qhov tseem ceeb kav kav. Lawv siv nyob rau hauv ntau lub tsev thiab kev lag luam los hloov cov roj nkev lossis roj roj. Lawv kuj tau siv rau hluav taws sprinkler cov tshuab tawm ntawm lawv qhov kev tiv thaiv kub.

Alloy 347 Stainless Hlau phaj ua yeeb yam zoo corrosion tsis kam uas yog piv rau 304.

Flanges welded nrog fittings

Carbon Steel Bars & Rods

Qhov no cov hlau stainless yeeb nkab feem ntau flanged los pab txhawb kev sib txuas nrog lwm cov kev lag luam xws li cov khoom siv hluav taws xob zoo li yuav tsum muaj cov piping nthuav dav.

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.

Alloy B2 kuj muaj qhov ua tau zoo heev rau pitting thiab kev nyuaj siab corrosion tawg.

Hastelloy B2 tiv thaiv kev tsim ntawm cov qoob loo ciam teb carbide precipitates nyob rau hauv lub weld cua sov cuam tshuam rau thaj chaw kev siv tshuaj nyob rau hauv cov txheej txheem kev siv tshuaj lom neeg. Cov cua sov cuam tshuam weld cheeb tsam txo cov nag lossis daus ntawm carbides thiab lwm yam theem kom ntseeg tau corrosion tsis kam.

304 Piping spools yog tsim los ntawm 304 stainless hlau, ib qho khoom siv nrov thiab nrov tshaj plaws hauv ntau cov ntawv thov uas xav tau kev tiv thaiv kom xeb thiab oxidation. Cov kev tshaj lij no yog preooss siv cov machinery thiab cov txheej txheem tshwj xeeb, uas paub meej tias lawv muaj tseeb thiab ntseeg tau.

Monel 400 2.4360 Nickel Alloy Yeeb Khoom ReBreedant rau ntsev thiab caustic daws teeb meem

Peb tsim cov khoom siv rau cov khoom siv thiab. Thaum cov neeg yuav khoom xav tau cov khoom sib txawv ua ntej kev teeb tsa, daim ntawv thov ntawm cov khoom siv ua ke ua ke ua ke yog hu ua piping spool thov. Muaj cov hlau stainless hlau spools cov khoom zoo li lwm cov khoom siv tau cov kab ua haujlwm hauv kev siv.

Lawv qhov chaw tsis txaus ntseeg dhau los ua kev tiv thaiv corrosion vim yog tsim ntawm Patina. Cov khoom siv incoloy muaj cov ntsiab lus hlau siab dua thiab tsis tshua kim dua li cov khoom lag luam tsis sib thooj. Lawv kuj tseem tiv taus corrosion los ntawm ntau cov ntaub ntawv, suav nrog cov chav thiab acids. Cov ntaub ntawv no tiv taus dej hiav txwv, acid roj thiab dej qab teb.

Txawm li cas los xij, lawv txoj kev nkees nkees yog siab dua li cov flanges. Qhov teeb meem loj ntawm lub qhov (socket) weld flanges yog kev pheej hmoo corrosion. Ib qho sib txawv ntawm flange thiab haum lossis cov yeeb nkab yuav tsum tau tswj ua ntej vuam. Corrosive kua los yog av noo tuaj yeem nrhiav hauv cov chaw no. Yog li, cov kua-khov kho no yuav ua rau lub cev xeb ntawm lub cev.

347 yeeb nkab thiab cov kua qaub rau cov kev ntsuas thiab kev txhim kho corrosion yog kev txhawj xeeb

Qeb 304 Stainless hlau yog feem ntau suav hais tias yog feem ntau cov roj av tsis tshua muaj.

Qhov tshwj xeeb ntawm Flange hom yog ua tiav ntawm ASME B16.5 cov qauv. Yog li flanges tau raug cais raws li; Weld caj dab, swb-rau, Socket Weld, tshiav, threaded dig muag. Weld Necked Flanges yog qhov yooj yim kom paub txog. Ib thooj cylindrical su nrog kev nce voj voog maj tau txuas nrog lub ntsiab hollow.

Kev ua kom zoo yog kev xyaum ua ke ntawm cov qauv hauv ib lub Rhiav lossis lwm qhov chaw sib dhos ua ntej thauj mus rau qhov chaw rau erection.

Inconel 625 Alloy tau siv dav hauv kev ua tshuaj, tswj kev ua qias tuaj, evapators, nuclear reactors, kev lag luam marine thiab ntxiv.
