API 5L nthawi zambiri imatanthawuza chitoliro cha mzere-API 5L, chitoliro cha mzere ndi kunyamula mafuta, nthunzi ndi madzi ochotsedwa pansi kupita kumakampani amafuta ndi gasi kudzera papaipi ya mzere.Chitoliro cha mzere chimaphatikizapo chitoliro chopanda msoko ndi chitoliro chachitsulo chowotcherera.Mapeto ake ali ndi malekezero athyathyathya, a ulusi ndi malekezero;njira zolumikizira ndi kuwotcherera, kulumikizana kolumikizana, kulumikizana kwa socket, ndi zina.

1. Njira yayikulu yopangira chitoliro chachitsulo chosasunthika chotentha (choyendera chachikulu):
Kukonzekera ndi kuyang'anitsitsa chubu → kutenthetsa kulibe kanthu → kuboola → kugudubuza chubu → kutenthetsa zitsulo → kukhazikika (kuchepetsedwa) m'mimba mwake → chithandizo cha kutentha △ → kuwongola machubu omaliza → kutsiriza → kuyang'anira (zosawononga, thupi ndi mankhwala, kuyendera ku Taiwan) → malo osungira
2. Njira yayikulu yopanga mapaipi achitsulo oziziritsa (wokokedwa) opanda msoko:
Kukonzekera billet→kukometsera zotola→kugudubuza kozizira(kujambula)→mankhwala otentha→kuwongola→kumaliza→kuwunika
