High kuchena gasi pombi kuvakwa

I. Nhanganyaya

Nebudiriro yenyika yangusemiconductoruye core-making maindasitiri, kushandiswa kwehigh-purity gasi mapaipiiri kuramba ichipararira. Maindasitiri akadai semiconductors, zvemagetsi, mushonga, uye chikafu zvese zvinoshandisa yakakwirira-kuchena gasi mapaipi kune akasiyana madhigirii. Naizvozvo, kushandiswa kwepamusoro-kuchena gasi mapaipi Kuvaka kunowedzera kukosha kwatiri.

2. Chikamu chekushandiswa

Iyi nzira inonyanya kukodzera kuisirwa uye kuyedzwa kwepombi dzegasi mumagetsi uye semiconductor mafekitori, uye kukwenenzverwa kwepaipi yakatetepa-yakavakirwa simbi isina gasi. Inokodzerawo kuvakwa kwemapaipi akachena mumishonga, chikafu uye mamwe mafekitori.

3. Process musimboti

Zvinoenderana nehunhu hwepurojekiti, kuvakwa kwechirongwa kunokamurwa kuita matanho matatu. Nhanho imwe neimwe inofanira kuongororwa zvakasimba kunaka uye kuchena. Nhanho yekutanga ndeye prefabrication yepombi. Kuti ive nechokwadi chehutsanana zvinodiwa, prefabrication yepombi inowanzoitwa mu1000-level prefabrication room. Nhanho yechipiri ndeyekuisa panzvimbo; danho rechitatu ndeyekuongorora system. Yekuongorora sisitimu inonyanya kuyedza guruva, dova remukati, oksijeni yemukati, uye hydrocarbon zvirimo mupombi.

4. Nzvimbo huru dzekuvaka

(1) Kugadzirira kusati kwavakwa

1. Ronga basa uye gadzira michina nemidziyo inoshandiswa mukuvaka.

2. Vaka kamuri rakagara rakagadzirwa rine hutsanana chiyero che1000.

3. Ongorora mifananidzo yekuvaka, gadzirira zvirongwa zvekuvaka zvichienderana nemaitiro eprojekiti uye mamiriro chaiwo, uye ita mapfupi ehunyanzvi.

(2) Pipeline prefabrication

1. Nekuda kwehutsanana hwepamusoro hunodiwa pamapombi egasi akachena, kuitira kuti kuderedze basa rekuisa welding panzvimbo yekuisa uye kuve nechokwadi chehutsanana, kuvakwa kwepombi kunotanga kugadzirwa mune 1000-level prefabricated room. Vashandi vekuvaka vanofanira kupfeka mbatya dzakachena uye kushandisa Machina nematurusi anofanirwa kuchengetwa akachena, uye vashandi vekuvaka vanofanirwa kuve nehutsanana hwakasimba kuti vaderedze kusvibiswa kwepombi panguva yekuvaka.

2. Kucheka kwepombi. Kucheka kwepombi kunoshandisa chigadziro chakakosha chekucheka pombi. Iyo yakachekwa yekupedzisira kumeso yakanyatso perpendicular kune axis yepakati mutsara wepombi. Paunenge uchicheka pombi, matanho anofanirwa kutorwa kudzivirira kunze kweguruva uye mhepo inosvibisa mukati mepombi. Zvishandiso zvinofanirwa kuiswa mumapoka uye kuverengerwa kuti zvifambise welding yeboka.

3. Welding yepombi. Pamberi pepombi welding, chirongwa chewelding chinofanirwa kuunganidzwa uye kupinza muotomatiki welding muchina. Test welding samples inogona chete kuiswa welded mushure mekunge sampuli dzave dzakakodzera. Mushure mezuva rimwechete re welding, sampuli dzinogona kusungirirwa zvakare. Kana sampuli dzichikodzera, iyo welding paramita icharamba isina kuchinjika. Iyo inochengetwa mumushini we welding, uye otomatiki welding muchina wakagadzikana zvakanyanya panguva yewelding, saka iyo weld mhando inokwanisawo. Hunhu hwewelding hunodzorwa nemicrocomputer, iyo inoderedza kukanganiswa kwezvinhu zvevanhu pamhando yewelding, inovandudza kushanda zvakanaka, uye inoburitsa emhando yepamusoro welds.

4. Welding process

High kuchena gasi pombi kuvakwa

(3) Kuiswa panzvimbo

1. Kuiswa panzvimbo-yepamusoro-kuchena gasi mapaipi kunofanirwa kuve kwakachena uye kwakachena, uye vanoisa vanofanira kupfeka magirovhosi akachena.

2. Nzvimbo yekugadzika yebhakiti inofanira kuenderana nezvinodiwa zvekugadzira zvemifananidzo, uye imwe neimwe yakagadziriswa inofanira kuvharwa nerubber rubber sleeve ye EP pipe.

3. Apo mapaipi akagadzirwa akaendeswa kunzvimbo, haagoni kurohwa kana kutsika, uye haagoni kuiswa zvakananga pasi. Mushure mekunge mabhuraketi aiswa, mapaipi anonamirwa pakarepo.

4. Iyo pa-saiti pombi welding maitiro akafanana neaya ari mudanho rekutanga.

5. Mushure mekunge kusungirirwa kwapera uye vashandi vakakodzera vakaongorora mashizha ekubatanidza welding uye majoini emagetsi pamapombi kuti ave akakodzera, shandisai welding joint label uye uzadze rekodhi rekodhi.

(4) Kuongorora kwehurongwa

1. Kuongorora kwehurongwa ndiyo danho rekupedzisira mukugadzirwa kwegasi yakakwirira. Inoitwa mushure mekuyedzwa kwepombi yekumanikidza uye kuchenesa kwapera.

2. Iyo gasi inoshandiswa pakuongorora system ndiyo yekutanga yegasi inokwanisa. Hutsanana, okisijeni yemukati, dova uye mahydrocarbon egasi zvinofanirwa kuzadzisa zvinodiwa.

3. Chiratidzo chinoedzwa nekuzadza pombi negasi rakakodzera uye kuchiyera nechiridzwa chiri pakubuda. Kana iyo gasi inoputika kunze kwepombi inokodzera, zvinoreva kuti chiratidzo chepombi chinokodzera.

5. Zvishandiso

Mapaipi egasi akanyanya-kuchena anowanzo shandisa mapaipi akatetepa-akakomberedzwa nesimbi inoenderana nezvinodiwa zvemaitiro epakati inotenderera, kazhinji 316L (00Cr17Ni14Mo2). Iko kune kunyanya matatu alloy element: chromium, nickel, uye molybdenum. Kuvepo kwechromium kunonatsiridza kushorwa kwesimbi isina tsvina mune oxidizing media uye inoumba layer yechromium-rich oxide film; nepo kuvapo kwe molybdenum kunonatsiridza kushorwa kwesimbi isina tsvina mune isiri-oxidizing media. Corrosion resistance; Nickel inhengo yekugadzira ye austenite, uye kuvapo kwavo hakungonatsiridze kushora kwesimbi, asiwo kunovandudza mashandiro esimbi.
