Line Pipe
Inoshandiswa kufambisa gasi, mvura, uye oiri mune ese uye echisikigo maindasitiri nezvimwe.
Casing: Casing ipombi yakakura-dhayamita iyo inoshanda sechigadziriso chemadziro emadziro emafuta negasi matsime, kana kubhowa. Inopinzwa mugomba uye inosimwa panzvimbo yekudzivirira ese ari maviri maumbirwo epasi uye tsime kubva pakudonha uye. kubvumira mvura yekuchera kuti itenderere uye kutorwa kuitike.Simbi Casing Mapaipi ane madziro akatsetseka & mashoma egoho simba re35,000 psi.
Tubing: Tubing ipombi inoshandiswa kutakura mafuta asina kuchena uye gasi rechisikigo kubva paoiri kana gasi layer kusvika pamusoro mushure mekuchera kwapera.Iyo inogadzirwa kuti imirire kumanikidzwa kunogadzirwa kubva pakubvisa maitiro.Tubing inogadzirwa nenzira imwechete secasing, kunze kwekunge imwe nzira inozivikanwa se "kugumburisa" inoiswa mukukora mapaipi.
