WHITE PAPER
WHY THESE 5 COMMON PIPE SUPPORT DESIGNS FAIL
Various common pipe support designs forget a very simple fact: crevice corrosion can quickly cause dangerous leaks.
1. BARE STEEL BEAM OR ANGLED SUPPORT
When a pipe is supported by a bare beam or angle, a crevice is formed where the pipe comes into contact with the support (see diagram). Condensation, rain, wash down or similar conditions where moisture is in contact with the pipe cause moisture to be drawn by gravity into the crevice where it becomes trapped. Once the water is trapped in the crevice it begins the process of softening the coating on the pipe until the coating separates from the bare steel. As soon as the bare steel is in contact with water the corrosion cell is formed and inevitable pipe failure is only a matter of time.
