Primer, Putty and

Tape, continued

For below ground installation adequate provision should be taken to protect the

coating from physical damage during pipe handling, lowering or backfilling operations.

The pipeline ditch should be free of rock or other sharp objects so the coated pipe

rests on a smooth bed of soil. Backfill materials should also be free of rock or other

sharp objects to avoid damage of the coating. After layer of debris-free soil has

covered the pipe, general backfill may be used.
