Casing Slips Type UC-3 are multi-segment slips with 1:4 taper (except size 8-5/8”). Every segment of one slip is forced equally while working. Thus the casings can keep a better shape. They should work together with spiders and insert bowls with same taper. The slips are designed and manufactured according to API SPEC 7K Specification for drilling and well servicing equipment.
