Before we built our first manifold we conducted research on existing designs and their related flow characteristics, in an effort to try and reduce issues related to sanding off. Sanding off was most commonly found in “log style” and to a lesser extent on “step down” or “zoomie style” manifolds. Following the path of this logic, we felt that if we could eliminate or improve the step down sections of the zoomie style manifold and create a consistent reduction in cone diameter from one end to the other, the result would be a superior constant flow and reduced turbulence inside the primary manifold chamber as well as the individual manifold ports. As it turns out, following the launch of our “new” manifold design (which was quickly adopted by a number of well service companies), we discovered that one of our customers, a large US based well service company has been using a tapered cone design since 1997 “because we came to the same conclusions – and while there are no guarantees, we feel strongly that our 11 year track record of reduced incidences of sanding off supports the benefits of this design”.
