Description
Casing Slips are specially developed to handle casing pipes during well drilling.
There are Casing Slips Type CMS, and Casing Slips Type UC-3.
Casing Slips Type CMS can handle casing pipes from 4-1/2 in (114.3 mm) to 30 in (762 mm) O.D..
Casing Slips Type UC-3 are multi-segments slips with 3 in/ft on the diameter taper slips (except size 8-5/8 in). Every segment of one slip is forced equally while working. Thus the casings could keep a better shape. They should work together with spiders and insert bowls with the same taper.
All casing slips are designed and manufactured according to API Spec 7K Specification for drilling and well servicing equipment.
