Abstract

The invention relates to a composite transfusion pipe lined with fluorine resin or organic resin, which comprises an external-layer transfusion pipe, a transfusion pipe, glue, a fluorine resin pipe or an organic resin pipe, a heat-insulation material or a phase-change energy-storage material, wherein the heat-insulation material or the phase-change energy-storage material is in the external-layer transfusion pipe, the transfusion pipe is in the heat-insulation material or the phase-change energy-saving material, and the hot-pressing expanding deforming fluorine resin pipe or the organic resin pipe is adhered to the internal surface of the transfusion pipe.

Description

Field of invention: [0001] The invention relates to a transfusion tube or an oil tube. Background technique: [0002] Chinese Patent 95102848.0 "A Porous Ceramic Liner and Its Manufacturing Method" has an outer layer of metal, an inner layer of porous ceramic material distributed in a cylindrical shape, and a layer between the inner and outer layers that is mainly composed of iron and contains a small amount of chromium, A transition layer for elements such as nickel. During manufacture, the powdered Fe 2 o 3 , Al, Zr, ZrO 2 、Al 2 o 3 and Y 2 o 3 Put it in the metal tube according to the molar ratio, and block the two ends with graphite plugs with flammable materials in the inner hole. Burn the flammable materials and ignite the internal powder under the condition that the metal tube rotates along the axis. The porous ceramic liner is obtained, which is better than the existing dense Al in heat insulation, sound insulation, toughness and bonding strength. 2 o 3 Cer...
