Kushungurudzika kweiyo API 5CTganda remafutamutsime remafuta: kuve nechokwadi chekuti casing inopinda mugomba inoenderera, isina kuputika kana kuremara, iyo casing inodiwa kuti ive neimwe simba, inokwana kuramba simba rekunze rinogamuchira.Naizvozvo, zvinodikanwa kuti uongorore kushushikana kwemukati wemukati casing.

1) Kudhonza simba
2) Extrusion simba
3) Kumanikidzwa kwemukati
4) Kupeta simba

Mukupedzisa, chivharo chiri mutsime chinonyanya kutakura masimba matatu ekutanga.Mamiriro ekumanikidzika ezvikamu zvakasiyana-siyana akasiyana, chikamu chepamusoro chinogamuchira simba rekukwevera, chikamu chepasi chine simba rekumanikidza kunze, uye chikamu chepakati chinogamuchira simba rekunze shoma.Paunenge uchigadzira tambo yekaseti, giredhi resimbi uye madziro emadziro evhavha inosarudzwa zvichienderana nepamusoro pekutarisa kwekuchengetedza chinhu.Kune iyo API yakajairwa casing, iyo general kuchengetedza chinhu che tensile ndeye 1.6-2.0, iyo yekuchengetedza iyo yekukanganisa kuramba ndeye 1.00-1.50, kazhinji 1.125, iyo yekuchengetedza chinhu chekumanikidza kwemukati ndeye 1.0-1.33, uye iyo yekuchengetedza chinhu chekumanikidza kuramba. panzvimbo yejekiseni yesimende ndiyo Inodiwa kukosha ndeye 0.85.Izvo zvinofanirwa kusimbiswa kuti iyo yekuchengetedza chinhu mukugadzirwa kwesimba retambo casing inosarudzwa zvinoenderana nenharaunda, stratum uye yakazotevera kubviswa kwemafuta uye gasi kugadzira gasi.Iye munhu ane ruzivo.Nekuda kwemasimba akasiyana ekunze anoshandiswa kune ekumusoro, epakati uye epasi zvikamu zvecasing tambo, iyo yakagadzirwa casing tambo inowanzo gobvu kana mamwe magiredhi esimbi mumadziro ekumusoro neakadzika, uye akatarisana nepakati, saka zvakakosha kuverenga. the casing.Mutsime iri.Muzviitiko zvakawanda, iyo casing iri kushanda mune corrosive media.Naizvozvo, pamusoro pekuda imwe dhigirii yesimba rekubatana, iyo casing inodikanwa kuti ive yakanaka yekuisa chisimbiso kuita uye kuti isaite ngura.
