This sway strut is fabricated from carbon steel and measures 240″ from pin to pin. The pipe is 6″ in diameter and has a load capability of 15,000 lbs. The components were completed with a hot-dipped galvanize finish and the pipe was coated with a shop primer. The function of a sway strut is to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction.
This particular sway strut will support a 30″ process line in a refinery. This type of support is necessary, because the current line has only a few I-beams for support. Additionally, the I-beams that support the line are very high off the ground and not capable of handling the large forces acting on the line. Due to the loads acting upon the pipe and length of the required strut, a heavy schedule pipe and heavier duty strut ends were necessary.
