Start and End Time
These parameters record the exact time when the job starts and ends. Monitoring the duration of operations helps in assessing efficiency and planning future tasks.
Shoulder and Slope Detection
Shoulder and slope detection features are essential for ensuring that the connections are made correctly. They help in detecting any anomalies in the threading process.
Connection Parameters
Target Type
The target type specifies the goal of the operation, such as achieving optimum torque. It guides the operator in setting the parameters correctly.
Thread Direction
The thread direction indicates whether the threading is right-hand or left-hand. This is crucial for ensuring compatibility and proper assembly.
Maximum, Optimum, and Minimum Torque
These parameters define the torque limits for the operation. The maximum torque is the highest allowable value, the optimum torque is the desired target, and the minimum torque is the lowest acceptable value.
Dump Percent
Dump percent indicates the allowable deviation from the target torque. It helps in maintaining precision in the operation.
Tailstock and Headstock Clamp Pressure
These parameters specify the pressure applied by the tailstock and headstock clamps. Proper clamping pressure ensures that the connections are held securely during the operation.
Achieved Torque and Turns
These values indicate the actual torque applied and the number of turns made during the operation. They help in verifying that the operation was completed as planned.
Connection Information
Pipe Size
The pipe size parameter specifies the diameter of the pipe being worked on. It is essential for setting up the bucking unit correctly.
Weight and Grade
These parameters indicate the weight and grade of the pipe or connection. They help in assessing the compatibility and strength of the materials.
Thread Type
The thread type parameter specifies the threading standard used. It ensures that the connections are compatible and meet industry standards.
Lubricant Information
This includes the brand, expiry, and type of lubricant used. Proper lubrication is crucial for preventing wear and ensuring smooth operation.
Slope / Shoulder Data Points
Slope Factor
The slope factor indicates the rate of change in torque with respect to turns. It helps in assessing the quality of the threading process.
Delta Turns
Delta turns measure the difference between the expected and actual number of turns. It helps in identifying any discrepancies in the operation.
Shoulder Torque and Turns
These parameters specify the torque and turns at the shoulder point. They are critical for ensuring a tight and secure connection.
Accept/Reject
This parameter indicates whether the operation was successful or if the connection needs to be redone. It helps in maintaining quality control.
Comments and Approval
Comments
Comments provide additional information or observations about the operation. They can include notes about any issues encountered or special instructions for future tasks.
Approval Status
The approval status indicates whether the operation has been accepted or rejected. It is crucial for maintaining quality assurance and ensuring that only properly completed connections are used.
Importance of Accurate Torque Reports
Accurate torque reports are essential for ensuring the safety and reliability of threaded connections. They provide a detailed record of the parameters and data points for each operation, helping in identifying any issues and maintaining high standards of quality control.
