Maximum available gap between pipe ends. Minimum gap = 0.
Maximum End Load are total from all loads based on standard weight steel pipe. End loads may differ for other pipe materials and/or wall thickness. Contact your GRINNELL Representative.
Gold color coded metric bolts and nuts are available upon request.
Max End Gap is for cut grooved standard weight pipe.
For 10 inch and 12 inch sizes where VdS Approval is required, refer to Figure 772, Technical Data Sheet G140.
See Approved Pressure Ratings starting on page 125.
Refer to Technical Data Sheet TFP1854 for more information.
