3.
Torque the studbolts and nuts of the clamping sections uniformly, as indicated by the Torque Values
in the PLIDCO Torque Chart for Clamp/Strongback located on page 4. The best results are obtained
by alternating the tightening of each nut maintaining an equal gap between the side bars.
4.
To complete assembly, ALL studbolts should be rechecked at the recommended torque.
If the pipeline has been shut down, re-pressuring should be done with extreme caution. Re-pressuring
should be accomplished slowly and steadily without surges that could vibrate the pipeline or produce a
sudden impact load. Industry codes and standards are a good source of information on this subject.
PLIDCO Clamp/Strongbacks should be stored in a dry environment to prevent the unpainted surfaces
from rusting. Storage temperatures should not exceed 120°F (49°C). It is best to exclude contamination,
light, ozones and radiation
PLIDCO Clamp/Strongbacks, as most PLIDCO products, have a unique serial number by which the fitting
is fully traceable
1.
After the pipeline is re-pressurized and field tested (see Re-pressuring and Field Testing for
precautions) the torque values should be checked again 4 hours after installation. Then, the torque
values should be checked again 24 hours after that.
2.
It is recommended that if the product is not being welded, that torque striping be applied from the
nuts to the sidebar of the PLIDCO Clamp/Strongback so any loosening of the bolts can be visually
seen during an inspection.
3.
6 months after installation it is recommended that a visual inspection occurs that checks for visible
signs of bolt/nut loosening, and general wear or corrosion.
4.
After the 6-month inspection occurs, a yearly visual inspection is recommended that checks for
visible signs of bolt/nut loosening, and general wear or corrosion.
