Abstract
The utility model discloses a liquefied natural gas pipeline support, it is in including supporting, the setting that is located the bottom stainless steel bottom plate, setting on the supporting are in the supporting with tetrafluoro friction pad, the setting that just keeps apart both between the stainless steel bottom plate are in PIR cold insulation layer on the stainless steel bottom plate, cover PIR cold insulation layer top and with PIR cold insulation layer is around forming the flexible closed bubble cold insulation cover of low temperature liquid phase pipe of a confined space. The utility model discloses safety, durable and long service life, difficult corruption have solved thereby the low temperature pipeline support holds the volatile cold and makes the low temperature pipeline quench, and the liquefied natural gas that causes meets the safety problem of the sharp gasification of heat.
Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of the gas equipment installation, especially, relate to a liquefied natural gas pipeline support.
[ background of the invention ]
Liquefied natural gas pipeline is the essential technological facility of transmission LNG in the gas source station, from LNG tank wagon to LNG storage tank, again from LNG storage tank to LNG gasification equipment, all need liquefied natural gas pipeline's transport, prior art transmits through stainless steel support bearing low temperature LNG pipeline, carry out heat preservation to the LNG pipeline simultaneously and handle, because support position keeps warm and can't accomplish, thereby make the pipeline that contacts with the support and quench, cause certain freezing and the intraductal gasification of LNG, increase the intraductal gasification volume of LNG.
Therefore, there is a need to provide a new lng pipeline bracket to solve the above problems.
[ Utility model ] content
A primary object of the present invention is to provide a support for a liquefied natural gas pipeline, which solves the problem of the low temperature pipeline support being cold in a volatile manner, and further the liquefied natural gas caused by the low temperature pipeline being cold is gasified rapidly in heat.
The utility model discloses a following technical scheme realizes above-mentioned purpose: a liquefied natural gas pipeline support comprises a support located at the bottom, a stainless steel bottom plate arranged on the support, a tetrafluoro friction pad arranged between the support and the stainless steel bottom plate and used for isolating the support and the stainless steel bottom plate, a PIR cold insulation layer arranged on the stainless steel bottom plate, and a low-temperature liquid phase pipe flexible closed-bubble cold insulation cover covering the PIR cold insulation layer and surrounding the PIR cold insulation layer to form a sealed space.
Further, the lower half part of the gas pipeline is embedded in the PIR cold insulation layer.
Further, the support is of a stainless steel structure.
Compared with the prior art, the utility model relates to a liquefied natural gas pipeline support's beneficial effect lies in: the low-temperature pipeline support is safe, durable, long in service life and not prone to corrosion, and the safety problem that the liquid natural gas is rapidly gasified when heated due to the fact that the low-temperature pipeline is cooled easily by the low-temperature pipeline support is solved.
[ description of the drawings ]
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
the figures in the drawings represent:
100 liquefied natural gas pipeline racks; 101 a natural gas pipeline;
1, supporting; 2, a stainless steel bottom plate; 3, a tetrafluoro friction pad; 4PIR cold insulation layer; 5, a low-temperature liquid phase pipe flexible closed-bubble cold insulation cover.
[ detailed description ] embodiments
Example (b):
referring to fig. 1, the present embodiment is an lng pipeline support 100, which includes a support 1 at the bottom, a stainless steel bottom plate 2 disposed on the support 1, a tetrafluoro friction pad 3 disposed between the support 1 and the stainless steel bottom plate 2 and separating the two, a PIR cold insulation layer 4 disposed on the stainless steel bottom plate 2, and a low-temperature liquid-phase tube flexible closed-bubble cold insulation cover 5 covering the PIR cold insulation layer 4 and enclosing the PIR cold insulation layer 4 to form a sealed space.
The lower half part of the gas pipeline is embedded in the PIR cold insulation layer 4.
The PIR cold insulation layer 4 is a low-temperature heat insulation layer structure made of polyisocyanurate.
The support 1 is of stainless steel construction.
The embodiment is that liquefied natural gas pipeline support 100 is safe, durable and long service life, and is difficult for corroding, thereby has solved low temperature pipeline support and has held the volatile cold so that the low temperature pipeline loses cold, the liquid natural gas that causes meets heat and gasifies rapidly the safety problem. Specifically, a stainless steel bottom plate 2, a tetrafluoro friction pad 3 and a PIR thermal insulation material layer 4 are added between a stainless steel support 1 and a pipeline to separate the low-temperature LNG pipeline from the support 1, so that the direct contact between the pipeline and the stainless steel support 1 is avoided, and the phenomenon that the temperature in the pipeline rises due to the conduction of the temperature of the low-temperature pipeline to cause redundant gasification and generate larger gasification is prevented; on the other hand, the PIR heat insulation material is added in the middle of the LNG pipeline, so that the heat insulation effect of the pipeline is well achieved, the PIR heat insulation material is closely combined with the flexible closed-bubble heat insulation layer on the periphery of the pipeline, the heat insulation effect of the pipeline is enhanced, and the heat insulation efficiency of LNG pipeline transmission is greatly improved; meanwhile, all the supports are made of stainless steel materials, so that the anti-corrosion effect is good, and the appearance is clean and bright.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
