Abstract
The tubing, in particular for the transport of petroleum fluids and their derivatives comprises a flexible inner tubular shell 10 for retaining the fluid and a flexible outer tubular shell 12 located coaxially around inner shell 10. Between the two shells 10, 12 there is an annular space 14 which can contain any fluid which might escape from inner shell 10. The tubing comprises an insert 30 of expanded polymer material within the space bounded externally by the inner surface of outer shell 12. <IMAGE>
