I. Product Overview
GB/T9948-2013seamless simbi pombi imhando yepamusoro-soro isina musono pombi inonyanyo shandiswa petroleum kupwanya process, uye inoshandiswa zvakanyanya mumidziyo yakakosha senge machubhu echoto, zvinopisa kupisa uye pombi dzekumanikidza mumafuta ekunatsa. Iyi chiyero inonyatso gadzirisa zvinhu, maitiro ekugadzira uye kuita zvinodiwa zvemapombi esimbi kuti ive nechokwadi chekushanda kwavo kwakadzikama munzvimbo dzepamusoro-soro, tembiricha yepamusoro uye yakanyanya-kumanikidza nharaunda.
2. Zvinhu uye kushanda
1. Zvinhu zvikuru
GB/T9948-2013mapaipi esimbi asina musono anogadzirwa nemhando dzakasiyana-siyana dzemhando yepamusoro alloy, kusanganisira:
Carbon structural simbi:20G, 20MnG, 25MnG
Alloy structural simbi:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Simbi isina simbi uye inodzivirira kupisa: 1Cr18Ni9, 1Cr18Ni11Nb
2. Core performance
Kudzivirira kwekushisa kwepamusoro: Inokodzera maitiro ekupisa kwepamusoro senge petroleum cracking (kusvika ku600 ° C kana kupfuura).
High pressure resistance: High-simba zvinhu zvinovimbisa kushanda kwakachengeteka kwemapaipi pasi penzvimbo dzakasimba.
Corrosion resistance: Special alloy components zvinonyatso ramba corrosion media senge hydrogen sulfide uye carbon dioxide.
Kuvimbika kwepamusoro: Kuomarara kwemhando yekudzora kunovimbisa kuti iyo mechaniki zvivakwa uye makemikari kuumbwa kwepombi dzesimbi zvinosangana neiyo GB/T9948 yakajairwa.
3. Manufacturing process
GB/T9948-2013 mapaipi esimbi asina musono anogadzirwa nekupisa kutenderedza uye kutonhora kudhirowa (kukunguruka):
Kupisa kutenderedza maitiro: kutenderera chubhu billet → kudziyisa → perforation → kukunguruka → saizi → kutonhora → kutwasanuka → kuongororwa kwemhando → kuchengetedza.
Kudhirowa kunotonhora (kukunguruka) maitiro: perforation → pickling → kutonhora kudhirowa → kupisa kupisa → kutwasanudza → kuona kukanganisa → kumaka → kuchengetedza.
Maitiro ese ari maviri anovimbisa yakakwirira dimensional kurongeka, yakatsetseka yepasi uye yakanakisa michina zvimiro zvemapombi esimbi.
4. Minda yekushandisa
GB/T9948 petroleum cracking pombi dzinoshandiswa zvakanyanya mu:
Petrochemical indasitiri: kupwanya unit, hydrogenation reactor, catalytic reforming michina
Indasitiri yekuchenesa oiri: yakakwira tembiricha yevira machubhu, kupisa exchanger, yakakwirira-kudzvanywa mapaipi
Kutakurwa kwegasi rechisikigo: corrosion-resistant, high-pressure gasi kutapurirana mapaipi
Boiler kugadzira: magetsi chiteshi boilers, maindasitiri boiler pombi masisitimu
5. Musika tarisiro
Nekukurumidza kusimudzira kweindasitiri yepetrochemical indasitiri uye kukura kwemusika wepasirese kudiwa, huwandu hwekutengesa hweGB/T9948 mapaipi esimbi isina musono huri kuramba huchikwira. Yayo yakanyanya kunaka tembiricha yekudzivirira uye kusadzivirirwa nekuora kunoita kuti ive iyo inofarirwa pombi zvinhu muminda yepetroleum kupaza uye kunatsa.
6. Chengetedzo yekutenga nekushandisa
Kusarudzwa kwezvinhu zvakasimba: Sarudza zvakakodzera GB/T9948 zvinhu (zvakadai se12CrMoG, 15CrMoG, nezvimwewo) maererano nemamiriro ekushanda (tembiricha, kumanikidza, corrosiveness).
Chitupa chehuhu: Ita shuwa kuti pombi yesimbi inosangana neiyo GB/T9948-2013 yakajairwa uye inopa yechitatu-bato rekuongorora rondedzero.
Kuisa uye kugadzirisa: Dzivisa kukuvadzwa kwemuchina panguva yekufambisa uye kuisirwa, uye gara uchitarisa kukora kwepombi uye mamiriro ekumanikidza.
GB/T9948-2013 petroleum cracking pombi yava sarudzo yakanaka yepetrochemical, kunatsa, gasi rechisikigo uye mamwe maindasitiri nekuda kwekunakirwa kwayo kwekupisa kwekushisa kwepamusoro, kupikisa kwepamusoro uye kusagadzikana kwekuora. Kusarudza zvinhu zvakakodzera (zvakadai se12CrMoG, 15CrMoG, nezvimwewo) uye kunyatsotevera zviyero zvinogona kuvimbisa kushanda kwakachengeteka kwenguva refu uye kugadzikana kwepombi.
