Casing Slips are specially developed to handle casing pipes during well drilling. There are Casing Slips Type CMS, Casing Slips Type UC-3. 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 same taper.
Casing slips type UC-3 are multi-segments slips with 3 in/ft on the diameter taper slips (except size 8 5/8’’). Every segment of one slip is forced equally while working, thus the casings could keep a better shaped. They should work together with spiders and insert bowls with same taper.
