I-ring bit Tunnel Forepoling Casing Advance
I-Forepoling, ekwabizwa ngokuba yi-tube umbrella, sisicelo esisetyenziselwa ukomeleza uphahla lwetonela kwiimeko zamatye ezaphukileyo.Inkqubo yokomba ibandakanyaibhokisiiityhubhu ezigrunjwa ngomthwalo ogqithisileyo njengeambrela kwaye zizaliswe yigrouting.I-KAT Casing System ivumela ukuqhuba lula kweetyhubhu ze-casing emhlabeni kunye nemfuno ephantsi ye-torque.Kwi-forepoling yanamhlanje kwakhona ii-fiberglass casings zinokusetyenziselwa ii-facebolts ezide kakhulu.
I-KAT Casing Systems esetyenziswa kakhulu kwi-forepoling yi-RoX+ 88,9/8, RoX 114,3/10 kunye ne-RoX 139,7/10.
