Methods of producing flexible pipe bodies, and flexible pipe bodies so produced

摘要

Flexible pipe bodies and methods for producing same are disclosed, als comprising a treatment step in order to reduce, inhibit or completely prevent microcrazing: A first method includes providing a tubular length of polymeric material for forming a polymeric layer of flexible pipe body, providing a strength layer radially outwards of the polymeric layer, and treating the polymeric layer with a non-ambient temperature and pressure. A second method includes providing a tubular length of polymeric material for forming a polymeric layer of flexible pipe body, providing a strength layer radially outwards of the polymeric layer, and treating a surface of the polymeric layer with a chemical to thereby change one or more physical property of the layer.
