I-API 5CT casing pipe

I-Casing ipayipi elikhulu elingudayamitha elihlanganiswa futhi lifakwe engxenyeni esanda kubhojwa ye-borehole futhi ngokuvamile ligcinwa endaweni yalo ngosimende. Futhi sihlinzeka nge-Seamless Casing ehlukahlukene kusukela ku-4-1/2’’-20’’ ebangeni H40, J55, K55, N80, L80, C95, P110 njll.
