Abstract
A multi-layer heat insulated pipeline, for conveying a first gas, includes an inner pipeline and an external pipeline. The inner pipeline is disposed within the external pipeline, and has a plurality of orifices. The first gas is conveyed within the inner pipeline along a pumping direction. The external pipeline includes an intake tube. A second gas is firstly heated or cooled and then injected into an interlayer between the external pipeline and the inner pipeline from the intake tube. The second gas is inactive with respect to the first gas. A first pressure of the first gas is less than a second pressure of the second gas.
Claims10
A multi-layer heat insulated pipeline for conveying a first gas, comprising:
- an inner pipeline within which the first gas is conveyed along a pumping direction, the inner pipeline having a plurality of orifices;
- and
- an external pipeline, wherein the inner pipeline is disposed within the external pipeline, the external pipeline includes an intake tube, wherein a second gas is selectively injected from the intake tube into a first interlayer between the external pipeline and the inner pipeline, the
- second gas being non-reactive with respect to the first gas, wherein the second gas is firstly heated or cooled and then injected from the intake tube into the first interlayer between the external pipeline and the inner pipeline, and wherein a first pressure of the first gas is less than a second pressure of the second gas.
A multi-layer heat insulated pipeline for conveying a first gas, comprising:
- a flexible metal hose within which the first gas is conveyed along a pumping direction, the flexible metal hose having a plurality of slits;
- and
- an external pipeline, wherein the flexible metal hose is disposed within the external pipeline, the external pipeline includes an intake tube, wherein a second gas is selectively injected from the intake tube into a first interlayer between the external pipeline and the flexible metal hose, the second gas being non-reactive with respect to the first gas, wherein the second gas is firstly heated or cooled and then injected from the intake tube into the first interlayer between the external pipeline and the flexible metal hose, and wherein a first pressure of the first gas is less than a second pressure of the second gas.
