Sezvatinoziva tese, mafuta emafuta anonatswa kubva mupetroleum. Mutengo wepetroleum uri kukwira makore ano, uye mutengo wekutyaira uri kuramba uchikwira. Mukuita kuburitsa oiri, mapaipi akawanda anoda kuiswa.

Heino kutarisa kune pipeline:

Tubing (GB9948-88) ichubhu yesimbi isina musono inokodzera muchoto chubhu, inopisa yekupisa uye pombi mune petroleum refinery.

Simbi pombi ye geological drilling (YB235-70) inoshandiswa pakuchera kwepakati nedhipatimendi re geological, iyo inogona kukamurwa kuita pombi yekuchera, dhiraivha collar, core pombi, casing pombi uye kunaya kwemvura zvinoenderana nekushandiswa kwayo.

Oiri pombi imhando yesimbi refu ine mhango chikamu uye isina akabatana akatenderedza, nepo petroleum inoputika pombi imhando yehupfumi chikamu simbi.

Tubing inoshandiswa zvakanyanya mukugadzirwa kwezvimiro uye zvemuchina semapombi ekudhira oiri, mashefu emotokari, mafuremu emabhasikoro uye simbi yekugezesa mifananidzo inofamba mukuvaka. Kushandisa petroleum cracking chubhu kugadzira zvindori zvinogona kuvandudza chiyero chekushandiswa kwezvinhu, kurerutsa maitiro ekugadzira, kuchengetedza zvinhu uye nguva yekugadzira, senge rolling bearing ring, jack sleeve, nezvimwewo, yakashandiswa zvakanyanya kugadzira simbi pombi. Petroleum inoputika chubhu kana akasiyana ezvakajairwa zvombo zvakakosha zvinhu, dhiramu, dhiramu uye zvichingodaro kune peturu inoputika chubhu kugadzira. Petroleum inoputika pombi inogona kupatsanurwa kuita denderedzwa pombi uye yakakosha-yakaita pombi zvinoenderana nechimiro chemuchinjiko-chikamu nzvimbo. Sezvo nzvimbo yepetroleum inoputika pombi ndiyo yakakura ine perimeter imwe chete, mvura yakawanda inogona kutakurwa nepombi yedenderedzwa.

API5CToiri casing inonyanya kushandiswa kutakura oiri, gasi rechisikigo, gasi, mvura uye zvimwe zvinwiwa nemagasi.

Inogona kukamurwa kuita seamless simbi pombi uye welded simbi pombi. Welded simbi pombi inonyanya kureva yakatwasuka seam simbi pombi, uye hombe-caliber petroleum casing kazhinji yakatwasuka seam yakanyudzwa arc welding simbi pombi. Nyika huru dzekushandisa dzechigadzirwa ichi dzinonyanya kugoverwa muMiddle East, Europe neAmerica.Api5ctcasing inogona kukamurwa kuita R-1, R-2 uye R-3 zvakatemwa zvichienderana nehurefu. Zvinhu zvikuru ndezviB, X42, X46, X56, X65, X70 zvichingodaro. Mukupisa kwakanyanya kwakanyanya uye yakanyanya kudzvanywa nharaunda, petroleum casing zvinhu pombi ine yayo yakasarudzika yakasarudzika mabhenefiti. Api5ct oiri casing kubva kune zvigadzirwa kusvika kune zvigadzirwa isati yaunzwa ye flattening bvunzo, tensile bvunzo, kukanganisa bvunzo, tensile bvunzo uye kumwe kuyedzwa kwakabatana.
