Ipayipi lomugqa we-API 5L lepayipi lomugqa kawoyela negesi

Amapayipi egesi angahlukaniswa ngezinhlobo ezintathu: amapayipi okuqoqa igesi, amapayipi egesi, kanye namapayipi okusabalalisa igesi ngokwendlela asetshenziswa ngayo.

①Ipayipi lokuqoqa igesi: ipayipi elisuka enhlokweni yomthombo wensimu yegesi lidlula esiteshini sokuqoqa liye esitshalweni sokwelapha igesi noma esiteshini sokuqala se-compressor yegesi, esisetshenziswa kakhulu ukuqoqa igesi yemvelo engalashwanga ekhishwe ku-stratum. Ngenxa yokucindezela okuphezulu komthombo wegesi, ingcindezi yepayipi lokuqoqa igesi ngokuvamile ingaphezu kuka-100 kgf/cm2, kanti ububanzi bepayipi bungu-50 kuya ku-150 mm.

②Amapayipi egesi: amapayipi avela ezitshalweni zokucubungula igesi noma eziteshini zokuqala ze-gas compressor zemithombo yegesi kuya ezikhungweni zokusabalalisa igesi, abasebenzisi abakhulu noma izindawo zokugcina igesi emadolobheni amakhulu, kanye namapayipi axhumana phakathi kwemithombo yegesi. Ngemva kokucubungula, ipayipi lihambisana nokuthuthwa kwepayipi. Igesi yemvelo ejwayelekile esezingeni eliphezulu (bheka ubuchwepheshe bokudlulisa igesi yepayipi) yingxenye eyinhloko yesistimu yonke yokudlulisa igesi. Ububanzi bepayipi legesi bukhulu kunobepayipi lokuqoqa igesi kanye nepayipi lokusabalalisa igesi. Ipayipi legesi elikhulu kunawo wonke linobubanzi obungu-1420 mm. Igesi yemvelo ithuthwa ngaphansi kwengcindezi isuka esiteshini sokuqala se-compressor kanye neziteshi ze-compressor eceleni komugqa. Ingcindezi yokudlulisa igesi ingu-70-80 kgf/cm2, futhi ubude obuphelele bepayipi bungafinyelela izinkulungwane zamakhilomitha.

③Ipayipi lokusabalalisa igesi: ipayipi elisuka esiteshini sokulawula ingcindezi yasemadolobheni kanye nesilinganiso liye emgqeni wegatsha lomsebenzisi linomfutho ophansi, amagatsha amaningi, inethiwekhi yamapayipi aminyene, kanye nobubanzi obuncane bamapayipi. Ngaphezu kwenani elikhulu lamapayipi ensimbi, amapayipi okusabalalisa igesi anomfutho ophansi angenziwa ngamapayipi epulasitiki noma ezinye izinto.

Insimbi ye-X-60 ene-alloy ephansi (umkhawulo wamandla angu-42 kgf/cm2) isetshenziswa kabanzi kumapayipi, futhi izinto ezinamandla aphezulu njenge-X-65 kanye ne-X-70 seziqalile ukusetshenziswa. Ukuze kuncishiswe ukumelana kokungqubuzana epayipini, amapayipi amasha ensimbi angaphezu kuka-426 mm ngokuvamile ambozwe ngezingubo zangaphakathi.

Amagesi anezakhiwo ezahlukene zomzimba athuthwa ngokulandelana ngepayipi elifanayo, kanye nokuhlolwa kokuthuthwa kwepayipi legesi yemvelo elinoketshezi kanye nelinoketshezi ku--70°C kanye no-77 kgf/cm2 high pressure. Uhlelo lokuthuthwa kwepayipi legesi yemvelo luqukethe izingxenye ezimbili: isiteshi sokudlulisa igesi yepayipi kanye nohlelo lomugqa. Uhlelo lomugqa luhlanganisa amapayipi, amakamelo e-valve eceleni komzila, izakhiwo zokuwela (bheka iphrojekthi yokuwela ipayipi kanye nephrojekthi yokuwela ipayipi), isiteshi sokuvikela i-cathodic (bheka i-anticorrosion yepayipi), uhlelo lokuxhumana kwepayipi, uhlelo lokuthumela kanye nokuqapha okuzenzakalelayo (bheka ukuqapha ipayipi), njll.

Ipayipi lensimbi liyizinto eziyinhloko zepayipi. Ipayipi lensimbi yokudlulisa igesi yemvelo liwumkhiqizo okhethekile wensimbi owakhiwe ngokucubungula okujulile kwepuleti (ibhande). Ngenxa yokwehluka kobuchwepheshe benqubo, ukuhlelwa kwensimbi yepayipi kunokwehluka okuthile ensimbini yepayipi ekhiqizwa abakhiqizi abahlukahlukene. Ngokuthuthuka okuqhubekayo kocwaningo lwensimbi yepayipi, iCanada namanye amazwe abeke izingxenye zokuhlola zensimbi yepayipi ye-X100 ne-X120. Kuphrojekthi yepayipi ye-Jining tie-line eShayina, insimbi yepayipi yebanga le-X80 yasetshenziswa esigabeni sokuhlola esingu-7.71km okokuqala. Ipayipi Legesi laseNtshonalanga-Mpumalanga elingu-4,843km ubude lomugqa wesiqu somugqa wesibili isebenzisa insimbi yepayipi yensimbi yebanga le-X80 enobubanzi obungu-1219mm, okwandisa ingcindezi yokudlulisa igesi ibe yi-12Mpa. Ngokuvamile, insimbi ye-X80 iyisakhiwo sezigaba ezimbili se-ferrite ne-bainite, insimbi yepayipi ye-X100 iyisakhiwo se-bainite, kanti insimbi yepayipi ye-X120 iyi-bainite ne-martensite ye-carbon ephansi kakhulu.

Kumapayipi egesi yemvelo, amandla, ukuqina kanye nokushiselwa yizinkomba ezintathu eziyisisekelo zokulawula ikhwalithi [6].
