MANUFACTURE OF FLEXIBLE PIPE CAPABLE OF RECEIVING SMALL CURVATURE RADIUS

摘要

Hose capable of assuming small bending radii, wherein its wall consists of at least one internal tube (2) made from a solid elastomeric composition of formulation adapted to the fluid to be conveyed and - over all or part of its length - of a layer (3) produced from a foamable elastomeric composition, the ratio of the thickness (e) of the solid elastomeric layer of the internal tube (2) to the total thickness (E) of the wall being between 0.08 and 0.95 and wherein the said hose may comprise integrated reference marks or hose clips. Process for making such a hose. Applications in the field of handling liquid, gaseous or pulverulent products and to circuits for fluids and/or air-conditioning of motor vehicles.
