Slip Crushing Solutions
Workstrings International® can help you determine maximum slip capacity and slip crushing calculations for your tubulars.
Avoid Pipe and Slip Damage Associated With High Tensile Loads
Workstrings was the first company to test drill pipe slips on actual drill pipe with a series of internal strain gauges. For more than two decades, our calculations have helped operators protect tubulars from high tensile loads.
Thousands of Designs With Zero Failures
Our Slip Crushing Analysis factors in actual slip design, length of die contact to pipe, drill pipe dimensions, and yield strength—with calculations verified by a series of load tests, and thousands of designs with no failure.
- Slip capacity: static load rating designating when slips may become damaged
- Slip crushing capacity: calculated static load designating when slips may damage pipe
Landing String Design
Maintaining the largest global fleet of landing strings, we will evaluate slip crushing for all casing and liner runs on the well.
Drill String Design
We will evaluate the slip-crushing capacity for each hole section and calculate slip crushing at each segment of the drill string.
Completion String Design
Workstrings will also evaluate the slip-crushing capacities for the various string configurations encountered in completion operations.
Slip Crushing Theory and Calculations
To determine slip crushing capacity, critical for avoiding pipe and slip damage, the Spiri-Reinhold Equation takes into account the following factors:
- Length of contact
- Radial contact
- Angle of contact
- Friction coefficient between bowl and slips
- Pipe grade and dimensions
Our Slip Crushing Calculations Equate to Operational Confidence
Over 25 years and a presence in 90 countries add up to a reliable track record. For a comprehensive analysis of your deepwater tubulars, let’s talk.
