Umbhobho we-API 5CT

Isingxobo ngumbhobho omkhulu odityanisiweyo kwaye ufakwe kwicandelo elisanda kumbiwa lomngxuma wequla kwaye ngokwesiqhelo.
igcinwe kwindawo enesamente. Kwaye sibonelela ngeeCasi ezahlukeneyo ezingenamthungo ukusuka ku-4-1/2’’-20’’ kwibakala H40, J55, K55,
I-N80, L80, C95, P110 njl Uluhlu lobude beCasing yi-R1, R2, R3, kunye nemisonto ye-BTC, LTC, STC. Ngokomandla
yentsimbi casing inokohlulwa ibe ibakala ezahlukeneyo zentsimbi, nzulu kakuhle, usebenzisa ibakala intsimbi ezahlukeneyo. Kwimekobume eyonakalisayo
kwakhona ifuna i-casing ngokwayo inokumelana nomhlwa. Kwimeko entsonkothileyo yokwakheka komhlaba indawo nayo yabuza i-casing
ukuba nomsebenzi wokuchasana nokuwa.
