Method of manufacturing a flexible tubular structure

摘要

The invention relates to a flexible tubular pipe (10) intended for offshore oil production and to its method of manufacture, said pipe comprising an impermeable internal duct and at least one sheet (20) made of a thermoplastic elastomer polymer of defined thickness around said internal duct (18). According to the invention said thermoplastic elastomer polymer comprises a polypropylene-based thermoplastic polymer and an elastomer based on an ethylene-propylene-diene terpolymer and it further includes a compatibilizer for increasing the miscibility between said polypropylene-based thermoplastic polymer and said elastomer based on an ethylene-propylene-diene terpolymer.
