Spiral Grooved Elbows

Spiral grooved elbows and straight piping creates the turbulence needed to keep plastic pellets away from the inner wall when being pneumatically conveyed.



The inside diameter is grooved spirally in a highly specialized process. Thereby reducing fines, angel hair, snakeskin and streamers that can clog convey lines. Both elbows and straight lengths can be spiral grooved.
