The first non-destructive test device to indicate the level of crosslinking in PEX-A (peroxide-cured) HMW-HDPE pipe for hot water and in-floor heating was recently sold by Inoex GmbH in Germany (U.S. office in Lancaster, Pa.). The vision-based device is mounted in the extrusion line after the crosslinking oven and cooling-water bath. (Crosslinking makes normally opaque PE more translucent.) Optical testing isn’t designed to replace chemical tests of crosslinking, but to give early warning of a change in the process to permit prompt correction, since off-line chemical tests on cut samples may take days to yield results. The non-destructive system currently tests crosslinking at up to 24 meters/min but could handle higher line speeds, Inoex says. Inoex has a system available for customer testing.

Apart from the triennial K Show, extrusion system suppliers don’t operate lines at trade fairs that much anymore.
