Casing Slips

Main Technical Features

● Types: Casing Slips Type CMS, 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 of 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 same

taper.

● All casing slips are designed and manufactured according to API Spec 7K Specification for

drilling and well servicing equipment.
