The grooved pipe joining method -- which dramatically reduces the amount of installation time as compared to welding, threading or flanging -- is now used extensively in a variety of piping applications.
Victaulic grooved products comprise a complete system: rigid and flexible grooved couplings, grooved accessories (such as grooved strainers and grooved suction diffusers), grooved valves, grooved fittings and grooved adapters, gaskets and grooving tools and accessories.
A drilled and grooved cover surface also becomes discontinuous to the extent that the little pillars that support the load are free to move in the nip; this also increases the wear rate.
When the drilled roll is also grooved, it further increases the surface to volume ratio and can tilt the balance so that chemical resistance can become a very real problem.
Three styles of grooved pins include GP200 full-length groove, GP210 half-length centered groove, and GP220 half-length offset groove.
There is extensive literature available on passively grooved feed sections, both theoretical and experimental.

Today, the grooved feed single screw extruder is widely accepted in Europe for high molecular weight polyolefin applications such as the extrusion of films, pipes and blow molded articles.
This paper introduces the reader to a modern grooved feed extrusion system using experimental results performed on a well instrumented 45 mm extruder with and without the grooved feed section.
A grooved feed section improves solids conveying and increases extruder pumping action, thereby raising output at a given extruder rpm, reducing energy put into the polymer, and lowering melt temperature.
As was reported in June, Exxon's Erderly found that the company's plastomer gave as much as 50% lower output/revolution than did standard LLDPE with a grooved feed.
