Maximum available gap between pipe ends. Minimum gap = 0
Max end gap and deflection are for cut grooved standard weight pipe. Values for roll grooved pipe are reduced by 50%.
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 TYCO Representative for details.
