High purity gas pipeline kev tsim kho

I. Kev Taw Qhia

Nrog txoj kev loj hlob ntawm kuv lub teb chawssemiconductorthiab core-making industries, daim ntawv thov ntawmhigh-purity gas pipelinesyog ua ntau thiab dav. Kev lag luam xws li semiconductors, electronics, tshuaj, thiab khoom noj khoom haus txhua tus siv high-purity gas pipelines mus rau txawv degrees. Yog li ntawd, kev siv high-purity gas pipelines Kev tsim kho kuj tseem ceeb heev rau peb.

2. Scope ntawm daim ntawv thov

Cov txheej txheem no tsuas yog tsim nyog rau kev teeb tsa thiab kev sim cov kav dej hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab cov vuam ntawm nyias-walled stainless hlau gas pipelines. Nws kuj tseem tsim nyog rau kev tsim cov kav dej huv hauv cov chaw muag tshuaj, khoom noj khoom haus thiab lwm cov chaw tsim khoom.

3. Txheej txheem txheej txheem

Raws li cov yam ntxwv ntawm qhov project, kev tsim kho ntawm qhov project tau muab faib ua peb kauj ruam. Txhua kauj ruam yuav tsum tau soj ntsuam xyuas kom zoo thiab huv si. Thawj kauj ruam yog prefabrication ntawm cov kav dej. Txhawm rau kom muaj kev huv huv, qhov prefabrication ntawm lub raj xa dej feem ntau yog ua nyob rau hauv 1000-theem prefabrication chav. Cov kauj ruam thib ob yog kev teeb tsa ntawm qhov chaw; cov kauj ruam thib peb yog kev kuaj xyuas qhov system. Kev ntsuam xyuas qhov system feem ntau yog kuaj cov hmoov av, cov dej dew point, cov ntsiab lus oxygen, thiab cov ntsiab lus hydrocarbon hauv cov kav dej.

4. Cov ntsiab lus tseem ceeb ntawm kev tsim kho

(1) Kev npaj ua ntej kev tsim kho

1. Npaj kev ua haujlwm thiab npaj cov tshuab thiab cov cuab yeej siv hauv kev tsim kho.

2. Ua ib chav prefabricated nrog kev huv huv ntawm 1000.

3. Txheeb xyuas cov duab kos, npaj cov phiaj xwm kev tsim kho raws li cov yam ntxwv ntawm qhov project thiab cov xwm txheej tiag tiag, thiab ua cov lus qhia luv luv.

(2) Pipeline prefabrication

1. Vim tias qhov kev huv huv siab xav tau rau cov kav dej purity siab, txhawm rau txo cov vuam ua haujlwm ntawm qhov chaw teeb tsa thiab xyuas kom huv, kev tsim cov kav dej yog thawj zaug prefabricated hauv chav 1000-theem prefabricated. Cov neeg ua haujlwm tsim kho yuav tsum hnav cov khaub ncaws huv thiab siv Machinery thiab cov cuab yeej yuav tsum tau ua kom huv si, thiab cov neeg ua haujlwm tsim kho yuav tsum muaj kev nkag siab zoo ntawm kev huv kom tsis txhob muaj kab mob ntawm cov kav dej thaum tsim kho.

2. Kev txiav yeeb nkab. Cov yeeb nkab txiav siv cov yeeb nkab tshwj xeeb txiav. Lub ntsej muag kawg txiav yog kiag li perpendicular mus rau axis center kab ntawm cov yeeb nkab. Thaum txiav cov yeeb nkab, kev ntsuas yuav tsum tau ua kom tsis txhob muaj cov plua plav sab nraud thiab cov pa paug hauv cov yeeb nkab. Cov ntaub ntawv yuav tsum tau muab faib ua pawg thiab suav nrog txhawm rau txhawm rau pab pawg vuam.

3. Cov yeeb nkab vuam. Ua ntej cov yeeb nkab vuam, qhov kev pab cuam vuam yuav tsum tau muab tso ua ke thiab tso rau hauv lub tshuab vuam tsis siv neeg. Kev kuaj vuam cov qauv tuaj yeem tsuas yog welded tom qab cov qauv tsim nyog. Tom qab ib hnub ntawm kev vuam, cov qauv tuaj yeem rov ua dua. Yog tias cov qauv tsim nyog, cov kev ntsuas vuam yuav tsis hloov pauv. Nws tau khaws cia rau hauv lub tshuab vuam, thiab lub tshuab vuam tsis siv neeg yog qhov ruaj khov thaum lub sijhawm vuam, yog li qhov vuam zoo kuj tsim nyog. Lub vuam zoo yog tswj los ntawm microcomputer, uas txo cov kev cuam tshuam ntawm tib neeg cov yam ntxwv ntawm cov vuam zoo, txhim kho kev ua haujlwm zoo, thiab tsim cov vuam zoo.

4. Vuam txheej txheem

(3) Kev teeb tsa hauv tsev

1. Lub installation ntawm high-purity gas pipelines yuav tsum huv si thiab huv si, thiab cov installers yuav tsum hnav hnab looj tes huv si.

2. Qhov kev ncua deb ntawm cov brackets yuav tsum ua raws li cov qauv tsim ntawm cov duab kos, thiab txhua qhov chaw ruaj khov yuav tsum tau them nrog lub tes tsho tshwj xeeb roj hmab rau EP yeeb nkab.

3. Thaum cov kav dej prefabricated raug thauj mus rau qhov chaw, lawv tsis tuaj yeem raug tsoo lossis nce toj, thiab tsis tuaj yeem muab tso ncaj qha rau hauv av. Tom qab muab cov hlua khi, cov kav dej tau daig tam sim ntawd.

4. Cov txheej txheem ntawm cov kav dej ntawm qhov chaw vuam yog tib yam li cov txheej txheem hauv prefabrication.

5. Tom qab vuam ua tiav thiab cov neeg ua haujlwm cuam tshuam tau tshuaj xyuas cov qauv vuam sib koom ua ke thiab cov vuam sib txuas ntawm cov kav dej kom tsim nyog, khij lub vuam sib koom ua ke thiab sau cov ntaub ntawv vuam.

(4) Kev ntsuas qhov system

1. Kev ntsuam xyuas qhov system yog kauj ruam kawg hauv kev tsim cov roj purity siab. Nws yog ua tiav tom qab lub raj xa dej siab kuaj thiab purging tiav.

2. Cov roj siv rau kev kuaj xyuas yog ua ntej ntawm tag nrho cov khoom tsim nyog. Kev huv huv, cov ntsiab lus ntawm cov pa oxygen, cov dej dew point thiab hydrocarbons ntawm cov pa roj yuav tsum ua tau raws li qhov yuav tsum tau ua.

3. Qhov ntsuas tau raug kuaj los ntawm kev sau cov raj xa dej uas tsim nyog thiab ntsuas nws nrog ib qho cuab yeej ntawm qhov hluav taws xob. Yog tias cov roj cua tshuab tawm ntawm lub raj xa dej tau tsim nyog, nws txhais tau hais tias qhov ntsuas lub raj xa dej tsim nyog.

5. Cov khoom siv

High-purity gas pipelines feem ntau siv nyias-walled stainless hlau kav raws li tus txheej txheem yuav tsum tau ntawm lub circulating nruab nrab, feem ntau yog 316L (00Cr17Ni14Mo2). Muaj peb lub ntsiab lus alloy: chromium, nickel, thiab molybdenum. Lub xub ntiag ntawm chromium txhim kho corrosion kuj ntawm stainless hlau hauv oxidizing xov xwm thiab tsim ib txheej ntawm chromium-nplua nuj oxide zaj duab xis; Thaum lub xub ntiag ntawm molybdenum txhim kho corrosion kuj ntawm stainless hlau nyob rau hauv non-oxidizing xov xwm. Corrosion tsis kam; Nickel yog lub hauv paus tsim ntawm austenite, thiab lawv lub xub ntiag tsis tsuas yog txhim kho corrosion ntawm hlau, tab sis kuj txhim kho cov txheej txheem kev ua haujlwm ntawm cov hlau.
