Setting Torque
Once the system is fully connected and proper power supply available, it is time to adjust the pump
pressure to the level needed on your job.
When tightening, use the manufacturer’s specications to determine the torque value which you will
ultimately require.
Torque sequence may vary from plant to plant and even within individual plants, depending upon the
gasket material, etc. Always abide by local procedures.
Next, use the pressure-torque conversion chart that is provided for the individual tool, similar to the one
below.
An example of nding the torque required is as follows:
Assume you are going to use a HTL-W2 tool to torque a 1 ¼ bolt to 835 ft.lbs.
1. First check the serial no. on the tool corresponds to the torque chart. On the left hand side of the
chart is the torque values. Find 835 ft.lbs on column
2. Then move across the chart until you come to a diagonal line.
3. At this point, move down to the bottom of the chart. The corresponding pressure value can be
found
4. For example the pressure is 5,300 psi on a tool to produce 835 ft.lbs.
5. Now set pressure on pump as follows in next section.
10,000 PSI = 1633 FT. LBS
