Abstract

A tube includes a tubular part of composite material with a thermosetting resin matrix. A metallic end coupling member is connected to one end of the tubular part and is engaged at least partially inside the tubular part. A tubular covering member of impermeable material is placed over the inner face of the tubular part and is integrally attached to the tubular part. An impermeable joint is formed between the end coupling member and the covering member. The inner face of the tubular part is covered by the end coupling member and the covering member.
