Peeling Force / Adhesion TestPeel s

Peeling Force / Adhesion Test
Peel strength shall be measured on the field joint coating for the PP and PE coated pipes.
Adhesion test shall be carried out on the field joint of FBE coated pipe.
The minimal waiting period between application of the coating and the peel force test is 48
hr for heat-shrinkable materials. The peel strength on the steel of the coated joint shall be
greater than the values given in Table 3 for ambient temperature and maximum operating
temperature
