Abstract
The utility model discloses a polyurethane high-temperature resistant pipeline, which belongs to the technical field of high-temperature conveying pipelines and particularly relates to pipelines. The polyurethane high-temperature resistant pipeline is characterized in that a polyurethane heat preservation layer is arranged on the inner wall of the pipeline, and a heat insulation layer is arranged on the outer wall of the pipeline. The polyurethane heat preservation layer is arranged on the inner wall of the pipeline, and during conveying of high-temperature fluid or steam, and the polyurethane heat preservation layer can enhance the high-temperature resistance of the pipeline. The pipeline can not be softened, deformed, corroded or react with oxygen in the air during conveying of high-temperature fluid or steam, thereby prolonging service life. The heat insulation layer is arranged on the outer wall of the pipeline so as to avoid fast conduction of heat energy and ensure physical safety of personnel nearby the pipeline.
Description
Technical field
The utility model belongs to high temperature conveyance conduit technical field, is specifically related to a kind of pipeline.
Background technique
Many industrial processes relate to fluid or gas are transported in another equipment in an equipment, and common this conveying realizes through pipeline.At present, when carrying high temperature fluid or steam, producer selects for use plastic tube or Ordinary Steel pipe to carry, and still, in using the plastic tube course of conveying, plastic tube is softening by high temperature fluid or steam easily, distortion, is unfavorable for the long-time conveying of high temperature fluid or steam.In using Ordinary Steel pipe course of conveying, the iron in the Ordinary Steel pipe reacts with airborne oxygen easily, generates iron oxide; Iron oxide is proceeded oxidation, and corrosion is constantly enlarged, and finally forms hole; Make the fracture of Ordinary Steel pipe, cause high temperature fluid or steam splash in the Ordinary Steel to be come out, not only pollute surrounding enviroment; And very easily endanger personal safety, working life is short.
Simultaneously, in carrying high temperature fluid or steam course, in case the people touches the Ordinary Steel pipe because of carelessness, touching the position will be injured, has great potential safety hazard.
Summary of the invention
The utility model technical problem to be solved provides a kind of polyurethane high temperature resistant pipeline, can improve the resistance to high temperature of pipeline, and stops the quick transmission of heat energy.
For solving the problems of the technologies described above, the technological scheme of the utility model is: a kind of polyurethane high temperature resistant pipeline is provided, comprises pipeline, it is characterized in that at inner-walls of duct polyurethane insulation coating being set, at pipeline outer wall thermal-protective coating is set.
Pipeline is processed by stainless steel material.
The beneficial effect of the utility model is:
1, the utility model is provided with polyurethane insulation coating at inner-walls of duct; In the process of carrying high temperature fluid or steam, polyurethane insulation coating can strengthen the resistance to high temperature of pipeline, in carrying high temperature fluid or steam course; Pipeline neither can soften, be out of shape; Can not react with airborne oxygen yet, can corrosion pipeline, can prolong the working life of pipeline.At pipeline outer wall thermal-protective coating is set, can stops the quick transmission of heat energy, guaranteed near the employee's of pipeline personal safety.
2, pipeline is processed by stainless steel material, and itself has decay resistance stainless steel.The chromium element is to make stainless steel obtain the basic element of corrosion resistance, and in the process of carrying high temperature fluid or steam, chromium can react with oxygen, forms the very thin patina of one deck, can stop stainlessly further to be corroded.
3, the utility model simplicity of design is easy to use, suitable penetration and promotion and industrialized production.
Description of drawings
Fig. 1 is the generalized section of the utility model.
Among the figure: 1, thermal-protective coating; 2, stainless steel pipeline; 3, polyurethane insulation coating.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
As shown in Figure 1, in the utility model, pipeline is a stainless steel pipeline 2, and the chromium element in the stainless steel pipeline 2 can react with oxygen, forms the very thin patina of one deck, can stop further being corroded of stainless steel pipeline 2.At stainless steel pipeline 2 inwalls polyurethane insulation coating 3 is set, polyurethane insulation coating 3 can strengthen the resistance to high temperature of stainless steel pipeline 2, plays the effect of double shielding with the patinas in the stainless steel pipeline 2.At stainless steel pipeline 2 outer walls thermal-protective coating 1 is set, can stops the transmission of heat energy, guaranteed near the employee's of pipeline personal safety.
It is to be noted; Above-mentioned mode of execution only is the utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets the utility model working principle, any be equal to or similar replacement all falls in the protection domain of the utility model.
Claims (2)
1. a polyurethane high temperature resistant pipeline comprises pipeline, it is characterized in that at inner-walls of duct polyurethane insulation coating being set, and at pipeline outer wall thermal-protective coating is set.
2. a kind of polyurethane high temperature resistant pipeline according to claim 1 is characterized in that pipeline processed by stainless steel material.
