Tests were carried out by an independent laboratory
using the following method:
- A single slip-on pipe tee clamp with
one case hardened set screw.
- Two pieces of Schedule 40 standard
black pipe at 24" long.
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:
- Divide Ultimate Load Capacity
by the appropriate safety factor.
- Check pipe Load Capacity Chart.
- Use the lower of the two results.
