Setting/Measuring The Groove Diameter

NOTICE

Due to differing pipe characteristics, a test

groove should always be performed before the first

groove of the day or when changing pipe size, schedule

or material. Groove diameter setting gauges are approx-

imate only and the groove diameter must be measured to

confirm proper size.
