Pipe For Your Structure |
Kee Klamp safety components are produced in a range of standard sizes to suit schedule 40 steel pipe, sizes 1/4" nominal to 2” nominal bore; also equivalent sizes of tubing in other materials. Tubing of other specifications can be used, providing the outside diameter is compatible with schedule 40 pipe. Pipe with a wall thickness of less than 1/8” can only be used in lightly loaded structure. A Kee Klamp component (size 5 – 9) can support an axial load of 2,000 lbs per set screw with the set screw tightened to a torque of 29 lbs/ft. (Rating includes a safety factor of 2:1.) This is normally obtained when the set screw is fully tightened using a ratchet wrench. |
