Embodiment 1

[0015] see figure 1 , an energy-saving double-layer thermal pipeline according to Embodiment 1 of the present invention, comprising a pipe body. Composite formation, middle layer 2 is superfiber, superfiber contains 61% (weight) SiO 2 , 27% CaO and 2% MgO.

[0016] The outer layer 1 of the pipe wall and the inner layer 3 of the pipe wall are made of stainless steel, wherein the material of the outer layer 1 of the pipe wall is SS304, the material of the inner layer 3 of the pipe wall is SS316L, and the average fiber diameter of the super fiber is 3 microns. The fiber index is 55%.

Embodiment 2

[0018] Unlike Example 1, the superfiber contains 65% by weight of SiO 2 , 30% CaO and 5% MgO. The average fiber diameter of the superfiber is 4 microns, and the fiber index of the superfiber is 58%.

[0019] Both the outer layer 1 of the pipe wall and the inner layer 3 of the pipe wall are made of stainless steel, the material of the outer layer 1 of the pipe wall is SS316L, and the material of the inner layer 3 of the pipe wall is SS304.

Embodiment 3

[0021] Unlike Example 1, the superfiber contains 67% by weight of SiO 2 , 33% CaO and 7% MgO. The average fiber diameter of the superfiber is 5 microns, and the fiber index of the superfiber is 60%.

[0022] Both the outer layer 1 of the pipe wall and the inner layer 3 of the pipe wall are made of stainless steel, the material of the outer layer 1 of the pipe wall is SS316T, and the material of the inner layer 3 of the pipe wall is SS316Ti.

Abstract

The invention relates to a thermal pipeline, in particular to an energy-saving double-layer thermal pipeline. The energy-saving double-layer thermal pipeline comprises a pipe body; a screw thread opening is formed on the port of the pipe body; the pipe body is formed by compounding a pipe wall outer layer, a middle layer and a pipe wall inner layer; the middle layer is made from a thermal insulation material which is a super fiber; and the super fiber contains 61 to 67 weight percent of SiO2, 27 to 33 weight percent of CaO and 2 to 7 weight percent of MgO. The invention has the advantages that: the energy-saving double-layer thermal pipeline is anti-corrosive, heat-resistant and particularly applicable to seaside and seaborne damp environment because the metal part of the energy-saving double-layer thermal pipeline is made of qualified stainless steel, is environment-friendly because the thermal insulation material is the super fiber which can resist the high temperature of 1,400 DEG C and is nontoxic and harmless to human bodies, is energy-saving because the heat taken away by smoke can be reduced effectively, saves the energy by 50 percent, is waterproof because the screw thread opening can prevent water effectively to keep a furnace body and the inner wall of the pipeline dry, is fireproof because the super fiber is a fireproof material applicable to inflammable environment such as woods and the like, has high safety performance, is convenient to install due to screw thread opening connection, and is attractive in appearance because the outer layer can be made into a mirror and coated in various colors.

Description

technical field [0001] The invention relates to a thermal pipeline, in particular to an energy-saving double-layer thermal pipeline. Background technique [0002] Thermal pipelines are pipelines that transport thermal energy media such as steam or superheated water. The characteristic of thermal pipeline is that the medium it conveys has high temperature, high pressure, and fast flow rate, which will bring large expansion force and impact force to the pipeline during operation. Therefore, in the pipeline installation, problems such as pipeline material, pipeline expansion and contraction compensation, pipeline support and hanger, pipeline slope, drainage and air release device should be solved to ensure the safe operation of the pipeline. The existing thermal pipelines have poor corrosion resistance, are not suitable for use in seaside and offshore humid environments, and have poor heat insulation. Contents of the invention [0003] In order to solve the above problems, ...
