Application:
For use on piping systems or equipment when unrestrained thermal movement must be allowed, but which must be restrained during impulsive or cyclic disturbance. The unit is not effective against low amplitude, high frequency movement. Preferred usage, with standard settings, to prevent destructive results due to earthquakes, flow transients, or wind load. Special settings are available to absorb the continuous thrust resulting from safety valve blow-off or pipe rupture. For the most effective operation of the unit, please specify the mounting position, vertical or horizontal.
Size Range:
PTP offers seven sizes with cylinder bores of 1 1/2 to 8 inches. These units have a normal load range of 3,000 lbs. to 130,000 lbs. All are made to include reservoirs in 6, 12, or 18 inch strokes, except the 1 1/2 inch size. The 1 1/2 inch size is offered only in 6 & 12 inch strokes only. Snubbers, as they are sometimes referred to, are available with remote reservoirs.

How to Order:

Please specify figure no., cylinder size, stroke, load, cold and hot piston settings, and piston end option. If clamp is required, please specify nominal pipe size, or special O.D. and clamp material. Please specify or describe any additional optional features or special settings required.
