Torque Turn Systems

WinCatt™ is a software tool which interacts with external control hardware to provide real time monitoring and control of tubular connection power tong make-up. The graphical user interface and logical software structure combined with powerful control, data acquisition and presentation capabilities enable the user to easily specify make-up parameters, control the make-up process and evaluate quality.

WinCatt™ was developed with an emphasis on the user's needs for reliability, accuracy, and ease of use. Key features are:
Function:

• monitors torque, turns, and rotational speed during make-up
• controls speed during make-up (optional)
• controls based on either final torque or final turns
• includes calibration management system
• includes automatic "Start Recording" & "Dump Valve Release"
• includes automatic descriptive comments with optional over-ride
• available with optional pressure test system

Analysis:

• analyzes make-up to determine: conformance to manufacturer's specification shouldering point for premium connections shouldering time, delta torque, delta turns
• reviews results from previous make-ups

Safety:

• limit torque to user specifies maximum during idle time

Reporting:

• job description
• summary reports of make-up results
• statistical analysis
• real time or post job make-up plots

Technical Specifications
Sampling Frequency:	User defined from 1 - 8000 Hz 500 Hz recommended
Recording Frequency:	Based on combination of delta torque and user defined delta time
Calibration Management:	Choice of calculated calibration based on load cell manufacturer specifications or local calibration based on user force standard. Shunt calibration with automatic "drift" tracking.
Response time:	Electronics < .5 ms Hydraulics - dependent on dump valve - typically 10 - 30 ms
Final torque:	Average = optimum torque +/- 1% Standard deviation < 2% under normal operating conditions
Operating temperature:	Computer, 5 - 50oC (40 - 122oF) Junction box, minus 30 - 80oC (minus 22 -180oF)
Torque accuracy:	max error (% of full scale) = sqrt[Local force standard error2 + arm length error2 + 0.152] -- Typically less than 1%.
Turns accuracy:	max error = +/-one pulse of turns counter
Pressure accuracy:	max error (% of F.S.) = sqrt[pressure standard error2 + 0.152] Typically less than 1%.
