American Maplan Corp.'s dual spider heads result in higher production rates and PVC pipe with improved physical properties, in diameters of 16-1,300 millimeters.
One of Maplan's most recent designs, the RD 1-7 head, produces pipe from 15-175 millimeters at a maximum rate of 2,200 pounds an hour. Using a single spider die, it would take three different heads to accomplish that rate. The RD 1-7 has five heating zones, while a typical die set has three zones.
The head design creates less back pressure, allowing for better throughput rates and wall-thickness control, reduction in overweight pipe, improved physical properties of the pipe and lower screw and barrel wear, Maplan said. Each RD head can make a wider range of pipe sizes.
American Maplan is based in McPherson, Kan.
