I have had the pleasure of working with your new pipe supports and have found them to be very useful. We use them on setup for staging pipe at various heights to allow for proper welding angles. They have proved to be very useful in rolling joints of pipe without scarring when adjusting angles and seam roll for fit ups. The ability to orientate during stacking to get a desired height has been very useful. We are currently attaching the supports to the pipe with rope at predetermined spacing to decrease in the need to adjust when the section is lowered in the ditch. This also cuts down on time shifting and moving them when you are lowering in pipe. We have stayed within the installation guidelines and had zero issues as far as structural integrity even when placing them under sags or overbends that may require a little more stability. All in all I really have to say it is a great product with versatile uses and the structural integrity is well worth it.
