Abstract
The utility model relates to an austenitic stainless steel pipe. The austenitic stainless steel pipe is characterized by comprising a first steel pipe (1), a glass steel pipe (3), a heat preservation interlayer (4), a second steel pipe (6) and a high-density polyethylene outer pipe (8) which are sequentially arranged from inside to outside. A first fiber layer (2) is arranged between the first steel pipe (1) and the glass steel pipe (3), a second fiber layer (5) is filled between the heat preservation interlayer (4) and the second steel pipe (6), an inner layer of the first steel pipe (1) is provided with an anticorrosive coating (7), and the first steel pipe (1) and the second steel pipe (6) are identical in material and made of austenitic stainless steel. The austenitic stainless steel pipe has the advantages of being abrasion-resisting, heat-resisting, corrosion-resisting and the like, is simple in structure and reasonable in design and has good practicability.
Description
Technical field
The utility model patent relates to a kind of Austenitic stainless steel pipe.
Background technique
Steel pipe is a kind of metallic conduit generally using both at home and abroad at present, mainly contain seamless steel pipe, steel pipes with straight, with helically welded tube etc., this class pipeline have working strength high, easy to use, but the insulation of this steel pipe, the anticorrosion poor-performing that waits, and especially easily corrosion, therefore be just easy to be subject in use external influence, thereby the practical life-span reducing, but in current improvement, conventionally adopt the mode of loading to fill between base tube and coating, the parcel poor-performing of entirety like this, install easily loosening, easily produce gap, be unfavorable for the use of pipeline.
Summary of the invention
The object of the utility model patent is to provide a kind of pipeline, thereby solves the defect in above-mentioned background technology.
This patent adopts following technical characteristics:
A kind of Austenitic stainless steel pipe, is characterized in that comprising the first steel pipe (1) setting gradually from inside to outside, Glass Steel Tube (3), heat preservation sandwich layer (4), the second steel pipe (6) and high density polyethylene (HDPE) outer tube (8);
Described the first steel pipe (1), between Glass Steel Tube (3), there is the first layer of fibers (2), between heat preservation sandwich layer (4) and the second steel pipe (6), be filled with the second layer of fibers (5), the internal layer of described the first steel pipe (1) has corrosion-inhibiting coating (7), described the first steel pipe (1) is identical with the material of the second steel pipe (6), is as Austenitic Stainless Steel;
The thickness of described the first steel pipe (1) is 4mm, and the thickness of heat preservation sandwich layer (4) is 5mm, and the thickness of Glass Steel Tube (3) is 3.5mm, and the thickness of the second steel pipe (6) is 4.5mm, and the thickness of high density polyethylene (HDPE) outer tube (8) is 2.7mm.
The material of described heat preservation sandwich layer (4) is urethane foam.
Described the first layer of fibers (2) and the second layer of fibers (5) are selected from carbon fiber or glass fibre.
Beneficial effect:
The utlity model has wear-resisting, heat-resisting, corrosion-resistant wait many merits, and simple in structure, reasonable in design, there is high practicability, can effectively improve the working life of whole pipeline, and the thickness of this pipeline is rationally can be effectively cost-saving and improve intensity.
Brief description of the drawings
Fig. 1 is the sectional view of this patent.
