Abstract
The utility model discloses a corrosion-resistant heat-preserving metal pipe with an expansion joint, relating to transportation course for transporting corrosive medium which needs to be thermally insulated in chemical process. The pipe is characterized in that the pipe structurally comprises a liquid transporting pipe and a heat preserving sleeve, wherein the liquid transporting pipe is a connected pipe which is made of zirconium or titanium and is provided with connecting flanges at both ends; the heat preserving sleeve is a stainless steel tube coaxially spaced at the outside of the liquid transporting pipe, and the ends of the stainless steel tube are fixedly sealed and connected with the side vertical sides of the connecting flanges at the ends of the liquid transporting pipe; a heat preserving medium intake pipe is arranged at one end of the heat preserving sleeve; and the other end of the heat preserving sleeve is provided with a heat preserving medium discharge pipe. The corrosion-resistant heat-preserving metal pipe can satisfy the heating and heat preserving requirements of the transported medium during the long-distance transportation of the corrosive medium. Meanwhile, by adopting the method of using composite material as transition medium to weld the non-ferrous material with steel, the utility model reduces the consumption of the non-ferrous material in the manufacturing process of the pipe and effectively controls the manufacturing cost of the pipe.
Description
Technical field
A kind of corrosion-resistant metal pipe with heat-insulating road with expansion joint relates to a kind of chemical process that is used for and is used to carry aggressive medium, and the medium course of conveying that need be incubated.
Background technique
In chemical process, having has dielectric corrosion need pass through line transportation in a large number.In actual production, a lot of occasions require the flowing medium in conveyance conduit must keep certain temperature.At present, the pipeline of conveying Korrosionsmedium adopts the titanium and the zirconium pipe of corrosion resistance and good usually, requirement for the conveyance conduit insulation, be to realize at pipeline outer wrapping one deck heat-insulating material, its heat insulation effect is bad, particularly can make the flowing medium in the pipeline produce bigger temperature drop under the long situation of medium temperature height, fed distance, the conveying that can't satisfy the bigger medium of some mobile temperature influence will require.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, and a kind of corrosion-resistant metal pipe with heat-insulating road that can effectively guarantee channel flow moving medium temperature, keep the band expansion joint of flowing medium flowability in the pipeline is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of corrosion-resistant metal pipe with heat-insulating road with expansion joint is characterized in that the structure of this pipeline comprises:
Liquid delivery tube-this liquid conducting pipes is zirconium or the titanium adapter that two ends have connecting flange;
Thermal insulation casing-this thermal insulation casing is the Stainless Steel Tube of coaxial spaced outside liquid conducting pipes, this stainless termination and fixing airtight connection of the attached method side elevation of liquid delivery tube termination; Be provided with the thermal insulation medium access tube at thermal insulation casing one end, relative end in addition is provided with the thermal insulation medium discharge tube.
A kind of corrosion-resistant metal pipe with heat-insulating of the present utility model road is characterized in that described thermal insulation casing is provided with the expansion pipe joint of the waveform of the projection that combines as a whole with thermal insulation casing.
A kind of corrosion-resistant metal pipe with heat-insulating of the present utility model road, can guarantee the heat tracing requirement of fed sheet of a media in the length of aggressive medium apart from course of conveying, simultaneously owing to adopted composite material to connect transition method with steel as nonferrous materials, reduce nonferrous materials consumption in the pipeline manufacturing, effectively controlled the manufacture cost of pipeline.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of corrosion-resistant metal pipe with heat-insulating road with expansion joint, the structure of this pipeline comprises: this liquid conducting pipes of liquid delivery tube 1-is zirconium or the titanium pipe joint that two ends have connecting flange 2; This thermal insulation casing of thermal insulation casing 3-is the Stainless Steel Tube of coaxial spaced outside liquid conducting pipes, this stainless termination and fixing airtight connection of the attached method side elevation of liquid delivery tube termination; Be provided with thermal insulation medium access tube 5 at thermal insulation casing one end, relative end in addition is provided with thermal insulation medium discharge tube 6.Its thermal insulation casing is provided with the expansion pipe joint 4 of the waveform of the projection that combines as a whole with thermal insulation casing.
The multiple layer of inboard titanium (or zirconium) the non-ferrous metal pipeline and the non-ferrous metal of adpting flange welds, the steel or stainless steel pipeline in the outside and basic unit's steel (or stainless steel) of adpting flange weld, realize two kinds of titanium (or zirconium) and steel (or stainless steel) connecting between can not the wlding material by flange as transition, to reach the requirement of pressure piping to structural strength.On outer sleeve, be respectively equipped with two interfaces, can feed steam (or hot water) flowing medium in the pipeline is carried out heat tracing.In order to prevent on steel (stainless steel) outer sleeve of pipeline, to be provided with the compensation that corrugated-type expansion joint carries out swell increment because of two kinds of material thermal expansion coefficient differences different structure thermal stress that causes of elongation that at high temperature expands.
