API 5L mutsetse pombi yemafuta uye gasi mutsetse pombi

Mapaipi egasi anogona kukamurwa kuita marudzi matatu: mapaipi ekuunganidza gasi, mapaipi egasi, uye mapaipi ekugovera gasi zvinoenderana nemashandisirwo azvo.

①Gasi rekuunganidza pombi: pombi kubva kutsime remunda wegasi kuburikidza nechiteshi chekuunganidzira kune gasi rekurapa gasi kana yekutanga gasi compressor chiteshi, iyo inonyanya kushandiswa kuunganidza isina kucheneswa gasi rechisikigo rinobviswa kubva mustratum. Nekuda kwekudzvanywa kwegomba regesi, kudzvanywa kwepombi yekuunganidza gasi kunowanzo pamusoro pe100 kgf/cm2, uye dhayamita yepombi i50 kusvika 150 mm.

②Mapombi egasi: mapaipi kubva kuzvigadziriso zvegasi kana kutanga gasi compressor zviteshi zvegasi kunzvimbo dzekuparadzira gasi, vashandisi vakakura kana magasi ekuchengetera mumaguta makuru, pamwe nemapaipi anotaurirana pakati pezvinobva gasi. Mushure mekugadzirisa, pombi inopindirana nekufambisa kwepombi. Hunhu hwakajairwa gasi rechisikigo (ona pombi yekufambisa gasi tekinoroji) ndiyo chikamu chikuru cheiyo yese gasi rekufambisa system. Iyo dhayamita yepombi yegesi yakakura kupfuura iyo yepombi inounganidza gasi uye pombi yekuparadzira gasi. Iyo yakakura gasi pombi ine dhayamita ye1420 mm. Iyo gasi yechisikigo inotakurwa pasi pekumanikidzwa kubva kunzvimbo yekutanga compressor station uye compressor zviteshi pamutsara. Iyo gasi yekufambisa kumanikidza ndeye 70-80 kgf/cm2, uye hurefu hwese hwepombi hunogona kusvika zviuru zvemakiromita.

③ Pombi yekuparadzira gasi: pombi kubva kudhorobha rekudzora uye metering chiteshi kune mushandisi mutsara webazi rine yakaderera kumanikidzwa, matavi akawanda, gobvu pombi network, uye diki pombi dhayamita. Mukuwedzera kune nhamba huru yepombi dzesimbi, pasi-kudzvinyirira gasi kugovera pombi inogonawo kugadzirwa nemapombi epurasitiki kana zvimwe zvinhu. .

X-60 yakaderera-alloy simbi (yakasimba muganhu we42 kgf / cm2) inoshandiswa zvakanyanya kune mapaipi, uye yakakwirira-simba zvinhu zvakadai se X-65 uye X-70 zvakatanga kushandiswa. Kuti uderedze kupokana mupombi, mapaipi matsva esimbi anopfuura 426 mm anowanzo kuve akaputirwa nemukati mejasi.

Magasi ezvimiro zvakasiyana zvemuviri anotakurwa zvakatevedzana mupombi imwe chete, uye gasi uye yemvura yakasikwa gasi pombi yekufambisa bvunzo pa -70°C uye 77 kgf/cm2 high pressure. Iyo yakasikwa gasi pombi yekufambisa sisitimu ine zvikamu zviviri: pombi yekufambisa gasi chiteshi uye mutsara system. Iyo line system inosanganisira mapaipi, makamuri evharuvhu munzira, kuyambuka zvivakwa (ona pombi yekuyambuka purojekiti uye pombi yekuyambuka purojekiti), cathodic chiteshi chekudzivirira (ona pombi inodzivirira kupisa), pombi yekutaurirana system, kutumira uye otomatiki yekutarisa system (ona pombi yekutarisa), nezvimwe.

Simbi pombi ndicho chinhu chikuru chepombi. Natural gasi transmission simbi pombi chinhu chakakosha metallurgical chigadzirwa chinoumbwa nekudzika kwakadzika kweplate (bhandi). Nekuda kwekusiyana kwehunyanzvi hwekuita, kurongeka kwesimbi yepombi kune mimwe misiyano musimbi yepombi inogadzirwa nevagadziri vakasiyana. Nekuenderera mberi kwekuvandudzwa kwepombi simbi yekutsvagisa, Canada nedzimwe nyika dzakaisa bvunzo zvikamu zveX100 uye X120 pombi simbi. Muchirongwa cheJining tie-line pombi muChina, X80-giredhi pombi simbi yakashandiswa kwechikamu chekuyedza 7.71km kekutanga. Iyo 4,843km-yakareba West-East Gasi Pipeline yechipiri-mutsara hunde mutsara inoshandisa X80 simbi yegiredhi pombi simbi ine dhayamita ye1219mm, iyo inowedzera gasi kutapurirana kumanikidza kusvika 12Mpa. Kazhinji kutaura, X80 simbi ndeye mbiri-chikamu chimiro cheferrite uye bainite, X100 pombi simbi chimiro che bainite, uye X120 pombi simbi ndeye Ultra-yakaderera kabhoni bainite uye martensite.

Pamapaipi egasi echisikigo, kusimba, kusimba uye weldability ndiwo matatu akanyanya kukosha ekudzora mhando zviratidzo [6].
