Abstract
The utility model discloses a corrosion resistance heat insulation pipeline, which comprises a carbon steel pipeline (1), wherein a modified graphite lining layer (2) is arranged on the inner wall of the carbon steel pipeline (1), and an outer jacket pipeline (3) is arranged on the outer surface of the carbon steel pipeline. The jacket pipeline is adopted by the corrosion resistance heat insulation pipeline, the corrosion resistance heat insulation pipeline is particularly suitable for being used for conveying high-melting-point materials, and the crystallization blockage of the materials is prevented.
Description
Technical field
The utility model relates to a kind of chemical industry changes pipe material, relates in particular to a kind of corrosion-resistant insulation pipe.
Background technique
Material need use the commentaries on classics pipe material when a container is transferred to another container.In the material transfer process; Because the particularity of material is high to material requirements, for example 3, generation 4-chloro-3 after 5-xylenol and the chlorosulfuric acid chlorination; Behind the 5-xylenol, need the liquid material after the chlorination be transferred to the another reaction kettle through pipeline and carry out decrease temperature crystalline; Because the fusing point of material is 116 ℃, material is the crystallization blocking pipe very easily, and contains a certain amount of hydrochloric acid in the material to the metallic conduit very corrosive.Therefore need the pipeline needs not only corrosion-resistant but also heat insulation effect is preferably arranged, making material be difficult for crystallization, to guarantee to change the material process normal.Existing pipeline is carbon steel or stainless steel insulation pipe, because hydrochloric acid is extremely strong to corrosion of metal property, thereby existing commentaries on classics pipe material is of short duration working life, needs often to change pipeline, has both influenced normally carrying out of producing, and has also increased the production input cost.
The model utility content
The model utility purpose: the purpose of the utility model is to change the problem that pipe material is subject to hcl corrosion to existing, provides that a kind of cost is low, the long service life corrosion-resistant insulation pipe of high insulating effect simultaneously.
Technological scheme: the described corrosion-resistant insulation pipe of the utility model, comprise carbon steel piping, the inwall of said carbon steel piping is provided with the modified graphite lining; The outer surface of said carbon steel piping is provided with the external jacket pipeline.The utility model is provided with the modified graphite lining at the inwall of carbon steel piping, and solvent-proof corrosion of acid of modified graphite salt tolerant and heat-transfer effect are better, have both solved etching problem and have also improved heat-transfer effect.
The utility model compared with prior art, its beneficial effect is: 1, the utility model adopts jacketed piping, and is suitable especially for the conveying of high-melting-point material, prevented that the crystallization of material from stopping up; 2, the utility model adopts modified graphite, owing to the acidproof anti-solvent corrosion of graphite, has avoided the etching problem of metallic conduit, has prolonged the working life of changeing the material pipeline greatly; General liner pipe employing enamel or Glassed Steel thermal conductivity brief biography thermal effect are poor, and the thermal conductivity that the utility model adopts modified graphite, graphite itself to have excellence can guarantee heat-transfer effect; Modified graphite is bigger than the flexibility of graphite, and is more not fragile than enamel or Glassed Steel pipeline vibration resistance, is useful for the occasion that some pipelines can shake; 3, the utility model course of working is simple, and convenient transportation is difficult for taking place broken, and environmentally safe in the use, usage range are extremely wide.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Be elaborated in the face of the utility model technological scheme down, but the protection domain of the utility model is not limited to said embodiment.
Embodiment:The said corrosion-resistant insulation pipe of the utility model comprises carbon steel piping 1, and the inwall of said carbon steel piping 1 is provided with modified graphite lining 2; The outer surface of said carbon steel piping is provided with external jacket pipeline 3.
Can use after the machine shaping, use this pipeline to solve the problem such as obstruction, corrosion of production process, practical effect is splendid.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
Claims (1)
1. a corrosion-resistant insulation pipe comprises carbon steel piping (1), it is characterized in that: the inwall of said carbon steel piping (1) is provided with modified graphite lining (2); The outer surface of said carbon steel piping is provided with external jacket pipeline (3).
