METHOD OF PRODUCING A FLEXIBLE PIPE BODY, AND FLEXIBLE PIPE BODY SO PRODUCED

摘要

Method of producing a flexible pipe body (100) to reduce, inhibit or completely prevent microcrazing, comprising: 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 radially inner surface of the polymeric layer with a chemical to thereby cause a change in the modulus of elasticity of the polymeric layer wherein the chemical has the effect of softening the polymer without dissolving the polymer.
