Abstract
Pipe (1) for conveying a fluid. It comprises a metal tube (2). The inner wall of the metal tube is coated with a layer (3) of a porous material permeable to the fluid conveyed. The fluid circulates in layer (3) in order to limit the pressure drops generated by the flow.
Claims24
A method for decreasing pressure drops generated by a fluid flow in a tube, the method comprising the following stages:
- putting a layer of a porous material onto the inner surface of said tube impermeable to said fluid, characterized in that:
- said material is selected with a permeability such that said fluid circulates in said layer and in an inner space defined by said layer.
A pipe for conveying a fluid while limiting pressure drops, pipe comprising a tube impermeable to the fluid conveyed and a layer of a porous material covering the inner wall of said tube, characterized in that the permeability of said material is such that said fluid circulates in said layer and in an inner space defined by said layer.
A method for decreasing pressure drops generated by a fluid flow in a tube, comprising:
- providing a tube impermeable to the fluid, the tube having a layer of porous material on the inner surface of the tube, the porous material having a permeability allowing the fluid to circulate in the layer of porous material;
- flowing the fluid through an inner space defined by the layer of porous material;
- and
- circulating the fluid in the layer of porous material.
