Marking the direction of flow is a requirement of ASME/ANSI A13.1. Flow arrows are available in banding tape rolls or individual self-adhesive labels. Arrow banding tapes are designed to wrap around the ends of pipe marker to indicate direction of flow. 360 degree visibility shows you at a glance which way pipe contents are flowing. Arrow banding tapes also aid to help secure pipe markers to slightly dirty pipes. Arrows may also be use to indicate rotation or flow on production equipment. Click on images for more information.
