Tests were carried out by an independent laboratory
using the following method:
One pipe was inserted into the vertical barrel of the clamp with the set screw tightened to 20 ft lbs torque, as shown in the above diagram. A Baldwin State Universal Testing Machine was used to pull the connections apart to determine the Ultimate Load Capacity. The above test results represent the Ultimate Load Capacity for each of the test conditions shown (no safety factors are included). At this point, for each of the listed tests conditions, failure occurred when the set screw would score the pipe, resulting in the pipe being pulled out of the clamp. To determine pipe and clamp sizes to support a required load, please use the following method:
