The utility model relates to an austenitic stainless steel conveying pipeline. The austenitic stainless steel conveying pipeline is characterized by comprising a steel pipeline body (10), a left flange (11) and a right flange (12); the left flange (11) and the right flange (12) are arranged at two lateral ends of the steel pipeline body (10), and connecting holes (13) are respectively formed in the upper portions and the lower portions of the left flange (11) and the right flange (12); the steel pipeline body (10) comprises a first steel pipe (1), a glass steel pipe (3), an insulation interlayer (4), a second steel pipe (6) and a high-density polythene 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 arranged between the insulation interlayer (4) and the second steel pipe (6), an anti-corrosion coating (7) is arranged on the inner layer of the first steel pipe (1), and both the first steel pipe (1) and the second steel pipe (6) are made of the austenitic stainless steel material. The austenitic stainless steel conveying pipeline has the advantages such as abrasion resistance, heat resistance, corrosion resistance, simple structure, reasonable design and high practicability.
Description
Technical field
The utility model patent relates to a kind of Austenitic Stainless Steel conveyance conduit.
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 conveyance conduit, it is characterized in that comprising steel pipe body (10) and be positioned at left flange (11) and the right flange (12) at steel pipe body (10) two ends, left and right, this left flange (11) and right flange (12) all there is up and down attachment hole (13);
Described steel pipe body (10) comprises 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:
