Type UC Casing Slips

Type UC Casing Slips

The UC casing slips are multi-segment slips with light weight, firm structure and large holding range. These casing pipe slips are easy to fit the changing of the external diameter of the casing pipes due to wear and tear. Casing slips type UC-3 are designed with a 3" taper. They should work together with spiders and insert bowls with same taper. The tools are manufactured in the standard of API 7K and SY5049-91 “Slips for Well Drilling".

Because of most casing strings' weight and the relatively thin pipe wall, it's important that the supporting casing slips provide full circumferential grip. They are hinged together to wrap around the casing and exert a more uniform pressure. With each segment carrying the same load, casing pipe slips automatically center the casing string within the bushing or spider. And the casings could also keep a better shape. Then to change the number of segments and liners, casing slips can suit different sizes of casing pipes. Liners are held in place by a liner Retainer Key and Cotter Pin.
