The UC casing slips
Introduction:
The UC casing slips
The UC casing slips are designed and manufactured in API 7K and SY5049-91 slips for welling drilling. It is manufactured in a structure of multi-segment pieces with firm structure, light weight and large holding range, which is easy to fit the changing of the external diameter of the casing pipes due to wear and tear.

Most casing strings' weight and the relatively thin pipe wall make it important that the supporting slips provide full
circumferential grip. The BAASH-ROSS Type UC-3 slips achieves this with many narrow segments. They are hinged together to wrap around the casing and exert a more uniform pressure. With each segment carrying the same load, they automatically center the casing string within the bushing or spider. The UC-3 has a 3" taper.
With changes in the number of segments and liners, it will handle strings from 16" OD to 42" OD. Liners are held in place by a liner Retainer Key and Cotter Pin.Casing Slips Type UC-3 are multi-segment slips with of 3in/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 shape. They should work together with spiders and insert bowls with same taper. The slips are designed and manufactured according to API Spec 7K.
