Victaulic grooved mechanical piping systems were used in all areas of DOKE including HVAC, fire protection and desalination, with pipe sizes ranging from 2" up to 60" (50.
Using Victaulic systems enabled prefabrication, whilst flame-free assembly using grooved products not only sped up installation times but kept welding to a minimum as local ambient temperatures rose over 50 degrees C.
If we are dealing with a drilled and grooved cover, it becomes almost impossible to get reproducible results because of the difficulties in accurately positioning the ball.
A drilled and/or grooved cover will "act" softer than a plain cover.
The insertion force is much less for the helical grooved pin than for the other pins tested.
In the comparison pictures, the knurled and standard grooved pins clearly show signs of damage from installation as the bottom halves of the expanded diameter have been skived off.
Since the end of the 1950s, extensive research on grooved feed extruders has been carried out [3-7].
Geometrical elements of the grooved feed section are changed by modifying the grooved sleeve.

Essentially, in a grooved feed extruder, the conveying and pressure build-up tasks are assigned to the feed section.
During the years that followed, several advances were made in grooved feed extruder technology.
But decades of European experience offer lessons on how to use grooved
feeds to run even resins like TPU, nylon, and PET.
But other equipment makers vigorously dispute Exxon's contention that grooved
feed throats are less preferable for processing metallocene resins.
Unlike smooth-bore machines, the force-fed grooved
section reportedly achieves 85-95% melting of pellets after 7-9 in.
Today, there are five basic families of rollers: bowed rolls, expander stretcher rolls, grooved
metal rollers, rubber idler rollers, and angle-grooved
, soft-rubber idler rolls.
