1 Tool hoist rating is based on API Specication 8C; however, casing load limit is further constrained by local interaction of slip dies with casing, which must not exceed the

efciency indicated for individual slip die sizes to avoid excess deformation. The slip to casing interaction hoist limit is calculated by multiplying the slip to pipe body load

efciency number by the casing hoist limit found in API Bulletin 5C2. From 5C2 the pipe body yield for 9.63” x 40.0 ppf L-80 Casing is 916,000 lbs. The slip efciency for

die 81793 used to run this casing is 80%. Therefore, the casing hoist limit is 80% x 916,000 lbs = 732,800 lbs or 366.4 tons.

2 CRTi hoist capacity must be reduced by the pressure end load during circulation.

3 Torque capacity may be limited by slip die/casing interaction. Where torque factors are provided, multiply this factor by the desired casing weight in ppf then multiply the

result by the casing yield strength to determine the slip die/casing interaction torque limit. If no value is provided, tool rating will be limiting for all standard casing grades.

4 Maximum allowable compressive load applied to the tool. Some compressive load may be reacted through the coupling. This rating does not take into account bearing

load limitations of the coupling.

5 CRTi circulation pressure capacity is generally governed by packer cup pressure capacity. Pressure capacity may be less than indicated if alternative seal arrangements

are used.

6 Overall tool length depends on seal arrangement.

7 Maximum ow rate is based on minimizing erosion rates when using typical uids. Erosion rates may vary based on uid contents. Please inspect tool bore regularly.

8 Common die sizes shown. All API casing sizes and weights with drift diameter above 5.87” are available.

9 Maximum pipe weight is dened by the API Specication 5CT drift diameter of the heaviest weight casing into which the CRTi assembled with the specied die

set will t.

10 Indicated minimum pipe weight is based on the assumption that control of average pipe inside diameter over die grip interval does not allow pipe body

area reduction less than 3.5% from nominal and additionally takes into account tool wear allowances, die penetration, casing deformation and tool stroke.

11 Non-standard radial stroke limit for this casing weight only.
