Nplhaib me ntsis Qhov Forepoling Casing Ua Ntej
Forepoling, tseem hu ua tube kaus, yog ib daim ntawv thov siv los ntxiv dag zog lub ru tsev hauv cov pob zeb tawg.Drilling system muajcasingcov raj uas tau drilled los ntawm overburden li ib lub kaus thiab puv nrog grouting.KAT Casing System tso cai rau kev tsav tsheb yooj yim ntawm cov kav hlau mus rau hauv av nrog qhov xav tau torque tsawg.Nyob rau hauv niaj hnub forepoling kuj fiberglass casings yuav siv tau rau ultra-ntev facebolts.
KAT Casing Systems feem ntau siv hauv forepoling yog RoX + 88,9/8, RoX 114,3/10 thiab RoX 139,7/10.
Cov hlab ntsha
Feem ntau ib pawg muaj ob peb steel casings ntawm 1.5 - 3 meters
Kev sib txuas los ntawm xov
Txhaj li qub rau grouting
Standard casing diameters: 88,9 - 114,3 - 139,7 - 168,3 hli
