Kugwiritsa ntchito
API 5L Grade A Application
API 5L Gulu Andi giredi yoyambira muyeso ya API 5L, ndipo imagwiritsidwa ntchito makamaka pamiyeso yotsika kwambiri.Chifukwa cha mphamvu zake zochepa, chitoliro chachitsulo cha Gulu A chimagwiritsidwa ntchito m'madera otsatirawa:
Mapaipi amadzi akumidzi ndi akumidzi: mapaipi omwe amagwiritsidwa ntchito kutengera madzi amchere.
Njira zothirira: Mipope yothirira m'gawo laulimi potengera madzi.
Ma Network Distribution Networks: Amagwiritsidwa ntchito m'njira zina zogawira gasi zotsika kwambiri kuti zinyamule gasi wachilengedwe kupita kwa makasitomala okhalamo komanso ogulitsa.
Kutulutsa kwa mafakitale: Kumagwiritsidwa ntchito potulutsa madzi otayidwa oyeretsedwa kuchokera kumadera akumafakitale m'malo opanda mphamvu.
Mapaipi Othandizira: Mapaipi omwe amagwiritsidwa ntchito ngati mapaipi othandizira kapena okonza pamalo opangira mafuta ndi gasi.
Ntchito ya API 5L Gulu B
API 5L Gulu Bchitoliro chachitsulo chimapereka mphamvu yapamwamba muyeso ya API 5L, ndikupangitsa kuti ikhale yoyenera pakugwiritsa ntchito mphamvu zapakatikati.Izi zimapangitsa chitoliro chachitsulo cha Gulu B kukhala njira yosunthika komanso yogwiritsidwa ntchito kwambiri, kuphatikiza:
Mapaipi akuluakulu otumizira mafuta ndi gasi: amagwiritsidwa ntchito kunyamula mafuta osakhwima ndi gasi wachilengedwe kuchokera pomwe amapangidwira kupita kumalo oyeretsera kapena kusungirako.
Mapaipi a Subsea: Amagwiritsidwa ntchito popanga minda yamafuta apansi pa nyanja ndi gasi komanso potengera zinthu.
Mapaipi a Mpweya Wothamanga Kwambiri: Amagwiritsidwa ntchito kunyamula kutentha kwambiri komanso kuthamanga kwambiri pamafakitale angapo.
Chitoliro cha Structural: Chifukwa cha makina ake abwino, amagwiritsidwanso ntchito pamapangidwe angapo ndi zomangamanga komwe kumafunika kupirira zovuta zambiri.
Njira Yopangira Mapaipi: Amagwiritsidwa ntchito kunyamula mankhwala osiyanasiyana ndi zamadzimadzi m'mafakitale monga kukonza mafuta ndi mankhwala.
