|
|
| 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
110,000 lbs. All are made to include reservoirs in 6, 10, 15, or 20 inch
strokes, except the 1 1/2 inch size. The 1 1/2 inch size is offered only
in 6 & 10 inch strokes only. Snubbers, as they are sometimes
referred to, are available with remote reservoirs. |
| Ordering: |
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. |
