With your information of pipe diameter, wall thickness (or DR), and the recommended interfacial pressure you may use the McElroy Slide Rule Pressure Calculator, the McElroy nomogram pressure calculator, or our online pressure calculator. To determine the gauge pressure in each case, follow the instructions on the calculator to determine the gauge pressure setting for use in the fusion mode of the selected McElroy Hydraulic Fusion Machine. Drag pressure should always be added to the calculated gauge pressure. Always consult the pipe manufacturer’s recommended parameters and procedures. For pipe outside the United States, use the temperatures prescribed by the applicable company, local, state, or federal standards.

To determine the gauge pressure in each case, follow the instructions on the calculator to determine the theoretical fusion pressure for use in the fusion mode of the selected McElroy Hydraulic Fusion Machine. Drag pressure should always be added to the theoretical fusion pressure. Always consult the pipe manufacturer’s recommended parameters and procedures.
