API 5CT tuubada daasadaha

Daboolku waa tuubo dhexroor weyn ah oo la geliyo oo la geliyo qayb dhawaan la qoday oo ka mid ah ceel-biyoodka oo sida caadiga ah lagu hayo sibidh. Oo waxaan bixinaa Casing kala duwan oo aan Xumaan lahayn laga bilaabo 4-1 / 2 ''-20'' ee fasalka H40, J55, K55, N80, L80, C95, P110 iwm.
