API 5CT casing pipe

Casing ndi chitoliro cham'mimba mwake chachikulu chomwe chimasonkhanitsidwa ndikulowetsedwa mugawo lomwe labowoleredwa posachedwa la borehole ndipo nthawi zambiri.
kugwiridwa ndi simenti. Ndipo timapereka Makasitole Osasinthika osiyanasiyana kuchokera ku 4-1/2''-20'' m'kalasi H40, J55, K55,
N80, L80, C95, P110 etc. Kutalika kwa Casing ndi R1, R2, R3, ndi ulusi wa BTC, LTC, STC. Malinga ndi mphamvu
wa casing zitsulo akhoza kugawidwa m'magulu osiyanasiyana zitsulo, bwino bwino, ntchito kalasi zitsulo zosiyanasiyana. M'malo owononga
imafunikanso kuti casing yokhayo ikhale ndi kukana kwa dzimbiri. Mu zovuta geologic chikhalidwe malo anafunsanso casing
kukhala ndi anti-collapse performance.
