Abstract
The invention provides a chemical delivery pipeline comprising a glass fiber reinforced plastic delivery pipe. A rock wool insulation support layer is arranged outside the glass fiber reinforced plastic delivery pipe, and a stainless steel wear layer is arranged outside the rock wool insulation support layer; support protrusions are arranged inside the rock wool insulation support layer and can effectively share radial tension during working of the glass fiber reinforced plastic delivery pipe to enable the glass fiber reinforced plastic delivery pipe to be stably disposed in the rock wool insulation support layer, and the glass fiber reinforced plastic delivery pipe is convenient to replace in case of damage; the glass fiber reinforced plastic delivery pipe is provided with a plurality of flow guide grooves in a working surface circumferentially, so that delivery area is increased, and internal fluid can be prevented from vortex, eddy flow and the like. The chemical delivery pipeline has the advantages that requirements of chemical enterprises on pipeline insulation, wear resistance and corrosion resistance can be met, minimal replacement is realized when the enterprises need to replace the pipeline, and enterprise cost is saved.
Description
Technical field
The invention belongs to chemical production field, particularly relate to a kind of chemical industry conveyance conduit.
Background technique
Industrial, various hot and cold medium transport pipeline, especially pressure piping, it is the important component part in the industries such as oil, chemical industry, light industry, weaving, metallurgy and electric power, be directly connected to the long-term, safe, stable of enterprise and economical operation, pipeline support plays bearing load, limits displacement and suppress the effects such as vibration.
In chemical industry, because the material of conveying often has corrosivity, can not long time be supported with general pipeline, and the insulation effect for chemical substance can not be ensured again.Use special pipeline, when enterprise is for certain series products not regenerative ratio, then when producing other products, often original anticorrosive nonreactive pipeline material that will become no longer for new product is anticorrosive, do not react, again change and need very big cost and time.
Summary of the invention
For solving the problem, the invention provides a kind of chemical industry conveyance conduit.
Concrete solution is: a kind of chemical industry conveyance conduit, comprises glass fibre reinforced plastics delivery pipe, and glass fibre reinforced plastics delivery pipe is outside equipped with rock wool heat-preservation supporting layer, and described rock wool heat-preservation supporting layer is outside equipped with stainless steel wearing layer.
Support protrusion is provided with in described rock wool heat-preservation supporting layer, these support protrusion effectively can share the tension force radially during the work of glass fibre reinforced plastics delivery pipe, glass fibre reinforced plastics delivery pipe is firmly placed in rock wool heat-preservation supporting layer, and occurs can being convenient for changing when damaging at glass fibre reinforced plastics delivery pipe.
Described glass fibre reinforced plastics delivery pipe circumferentially offers multiple guiding gutter on working surface, not only adds conveying area, but also can prevent the phenomenons such as internal flow eddy generation, eddy flow.
Beneficial effect of the present invention is: a kind of chemical conveying pipe, can meet chemical enterprise for pipe insulation, wear-resisting, erosion-resisting requirement, can accomplish again the replacing of minimum degree, saved the cost of enterprise when enterprise needs to change pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is front view of the present invention.
Wherein:
1. glass fibre reinforced plastics delivery pipe 2. rock wool heat-preservation supporting layer 3. stainless steel wearing layer 4. support protrusion
5. guiding gutter
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
As Figure 1-Figure 2: a kind of chemical industry conveyance conduit, comprises glass fibre reinforced plastics delivery pipe 1, and glass fibre reinforced plastics delivery pipe 1 is outside equipped with rock wool heat-preservation supporting layer 2, described rock wool heat-preservation supporting layer 2 is outside equipped with stainless steel wearing layer 3.
Support protrusion 4 is provided with in rock wool heat-preservation supporting layer 2, these support protrusion 4 effectively can share the tension force radially when glass fibre reinforced plastics delivery pipe 1 works, glass fibre reinforced plastics delivery pipe 1 is firmly placed in rock wool heat-preservation supporting layer 2, and occurs can being convenient for changing when damaging at glass fibre reinforced plastics delivery pipe 1.
Glass fibre reinforced plastics delivery pipe 1 circumferentially offers multiple guiding gutter 5 on working surface, not only adds conveying area, but also can prevent the phenomenons such as internal flow eddy generation, eddy flow.
Beneficial effect of the present invention is: a kind of chemical conveying pipe, can meet chemical enterprise for pipe insulation, wear-resisting, erosion-resisting requirement, can accomplish again the replacing of minimum degree, saved the cost of enterprise when enterprise needs to change pipeline.
