Pipe yemutsara yeAPI 5L yepombi yemafuta negesi

Mapaipi egasi anogona kukamurwa kuita mhando nhatu: mapaipi ekuunganidza gasi, mapaipi egasi, uye mapaipi ekuparadzira gasi zvichienderana nemashandisirwo azvo.

①Mapaipi ekuunganidza gasi: mapaipi anobva pamusoro petsime remunda wegasi achipfuura nepachiteshi chekuunganira gasi kuenda kufekitari yekurapa gasi kana pachiteshi chekutanga chekukwenenzvera gasi, icho chinonyanya kushandiswa kuunganidza gasi rechisikigo risina kugadziriswa rakatorwa kubva muchikamu. Nekuda kwekumanikidzwa kwakanyanya kwetsime regasi, kumanikidzwa kwepaipi yekuunganidza gasi kunowanzova pamusoro pe100 kgf/cm2, uye dhayamita yepombi ndeye 50 kusvika 150 mm.

②Mapaipi egasi: mapaipi anobva kumafekitori ekugadzira gasi kana nzvimbo dzekutanga dzemacompressor egasi kubva kunzvimbo dzinopa gasi, vashandisi vakuru kana nzvimbo dzinochengeterwa gasi mumaguta makuru, pamwe nemapaipi anotaurirana pakati penzvimbo dzinopa gasi. Mushure mekugadzirisa, pombi inoenderana nekutakurwa kwepaipi. Gasi rechisikigo remhando yepamusoro (ona tekinoroji yekutumira gasi repaipi) ndiro chikamu chikuru chehurongwa hwese hwekutumira gasi. Dhayamita yepombi yegasi yakakura kupfuura yepombi inounganidza gasi nepombi inogovera gasi. Pombi yegasi hombe ine dhayamita ye1420 mm. Gasi rechisikigo rinotakurwa pasi pekumanikidzwa kubva kunzvimbo yekutanga yecompressor uye nzvimbo dzecompressor dziri pamutsetse. Kumanikidzwa kwekutumira gasi i70-80 kgf/cm2, uye hurefu hwese hwepombi hunogona kusvika zviuru zvemakiromita.

③Mapaipi ekugovera gasi: mapaipi anobva kunzvimbo yekudzora kumanikidzwa kweguta kuenda kumutsara webazi remushandisi ane kumanikidzwa kwakaderera, matavi akawanda, network yemapombi akakora, uye dhayamita diki yemapombi. Kuwedzera kune huwandu hwakawanda hwemapaipi esimbi, mapaipi ekugovera gasi ane kumanikidzwa kwakaderera anogonawo kugadzirwa nemapaipi epurasitiki kana zvimwe zvinhu.

Simbi ine simba shoma yeX-60 (muganho wesimba re42 kgf/cm2) inoshandiswa zvakanyanya pamapaipi, uye zvinhu zvine simba rakakwirira zvakaita seX-65 neX-70 zvatanga kushandiswa. Kuti kuderedze kusimba kwekukweshana mupaipi, mapaipi matsva esimbi anopfuura 426 mm anowanzo putirwa nependi yemukati.

Magasi ane hunhu hwakasiyana anotakurwa zvakatevedzana mupaipi imwe chete, uye bvunzo dzekutakura mapaipi egasi negasi remvura pa -70°C uye 77 kgf/cm2 high pressure. Sisitimu yekufambisa mapaipi egasi remvura ine zvikamu zviviri: nzvimbo yekutumira gasi repaipi uye sisitimu yemutsetse. Sisitimu yemutsetse inosanganisira mapaipi, makamuri evharuvhu ari munzira, zvivakwa zvinoyambuka (ona purojekiti yekuyambuka mapaipi uye purojekiti yekuyambuka mapaipi), chiteshi chekudzivirira cathodic (ona anticorrosion yemapaipi), sisitimu yekutaurirana mapaipi, sisitimu yekuendesa uye yekutarisa otomatiki (ona ongororo yemapaipi), nezvimwewo.

Pombi yesimbi ndiyo chinhu chikuru chinogadzirwa papombi. Pombi yesimbi inotumira gasi rechisikigo chigadzirwa chakakosha chesimbi chinoumbwa nekugadzirwa kwakadzika kweplate (bhandi). Nekuda kwekusiyana kwetekinoroji yemaitiro, kurongeka kwesimbi yepombi kune musiyano wakati musimbi yepombi inogadzirwa nevagadziri vakasiyana-siyana. Nekuvandudzwa kuri kuramba kuchiitwa kwekutsvaga kwesimbi yepombi, Canada nedzimwe nyika dzakaisa zvikamu zvekuyedza zvesimbi yepombi yeX100 neX120. Muchirongwa chepipeline yeJining tie-line muChina, simbi yepombi yeX80-grade yakashandiswa pachikamu chekuyedza che7.71km kekutanga. Pipeline yeGasi yeWest-East yakareba 4,843km yemutsetse wechipiri wetrunk inoshandisa simbi yepombi yeX80 grade ine dhayamita ye1219mm, izvo zvinowedzera kumanikidzwa kwekutumira gasi kusvika 12Mpa. Kazhinji, simbi yeX80 chimiro chedual-phase cheferrite nebainite, simbi yepombi yeX100 chimiro chebainite, uye simbi yepombi yeX120 i ultra-low carbon bainite nemartensite.

Kune mapaipi egasi rechisikigo, simba, kusimba uye kuchinjika kwemvura ndizvo zviratidzo zvitatu zvinonyanya kukosha zvekudzora hunhu [6].
