Notes:
a. Maximum available gap between pipe ends. Minimum Gap = 0
b. Gold color-coded metric bolt sizes for DN50 - DN300 couplings are available upon request.
c. Maximum Pressure and End Load are total from all loads based on standard weight steel pipe.
Pressure ratings and end loads may differ for other pipe materials and/or wall thickness. Contact
GRINNELL Mechanical Products for details.
d. Maximum End Gap and Deflection is for cut grooved standard weight pipe. Values for roll
grooved pipe will be 1⁄2 that of cut grooved pipe.
