Meaning and Use 3.1 Since the pipe coating is subject to concentrated pressure exerted by the weight of the pipe and the backfill, this test is mainly used to determine the resistance of the coating to penetration or deformation under controlled conditions. 3.1.1 If the coating is not penetrated, the deformation of...
Maksud dan Tujuan 4.1 The test will provide information about the ability of the coating applied to the pipe to resist cracking, peeling or other mechanical damage caused by bending. Since the test is applicable to commercially produced coated pipes, the results can be directly used to select similar service materials....
