Abstract
A process for producing a thermoplastic composite pipe is provided. The thermoplastic composite pipe thus produced contains a liner, two or more composite layers composed of tape laminas, and a single- or multilayer intermediate lamina arranged between different composite layers. Composite formation between identical polymers in the process achieves improved adhesion. The thermoplastic composite pipe is especially suitable for offshore applications in oil or gas production.
