J55 K55 N80 Oiri Tubing uye Casing Steel Pipe
Oiri casing ipombi yesimbi inoshandiswa kutsigira madziro emafuta uye gasi matsime kuti ave nechokwadi chekushanda kwakajairika kweiyo mafuta mutsime mushure mekuchera uye kupera.Tsime rega rega rinoshandisa akati wandei akaturikidzana zvichienderana nekudzika kwakasiyana kwekuchera uye geological mamiriro.Cement simende inoshandiswa mushure mekunge casing yadzikiswa mutsime.Kusiyana nepombi dzemafuta uye pombi dzekuchera, haigone kushandiswa zvakare uye inguva imwe chete inodyiwa zvinhu.Naizvozvo, kushandiswa kwekasikisi kunodarika 70% yemapombi ese ematsime emafuta.

Kuongorora kunoonekwa kwepombi pamusoro
Dimension check
Mechanical bvunzo pane tensile simba, goho simba uye elongation
Kuongorora kwemakemikari
NDT bvunzo inosanganisira Magnetic particle, Ultrasonic Test, Hydrostatic Test
Charpy impact bvunzo
Flattening miedzo
Muedzo wekuoma
Drift test
Thread inopera tarisa ne thread geji uye coupling cheki
J55 neK55 zvinhu zvakafanana mukugadzirwa kwemakemikari uye mashandiro emuchina, kunyanya J55 ine yakaderera yakaderera tensile inodiwa uye yakaderera elongation, mamwe maratidziro akafanana senge nzira dzekurapa kupisa, NDE bvunzo, Charpy Impact bvunzo, hydrostatic bvunzo.
J55/K55 simba shoma regoho: 379-552 Mpa;
J55 shoma shoma simba: 517 Mpa, elongation ≥ 19%;
K55 zvishoma kusimba simba: 655 Mpa, elongation ≥ 15%.
