Abstract
The invention discloses a novel corrosion resistant pipeline-composite pipeline with steel jacket-to overcome the disadvantages of the existing corrosion resistant pipeline. The pipeline made from corrosion resistant material is sheathed into a steel shell, the outer wall of the corrosion resistant pipeline has certain distance with the inner wall of the steel shell, and proper vent holes are designed at proper positions on the steel shell. The steel shell increases mechanical strength, and the internal sleeve takes corrosion and abrasion resistant effect. The invention is a substitute product of the existing corrosion resistant pipeline.
Description
Technical field:
The present invention relates to a kind of making method of anti-corrosion pipeline, be applied to carry have Korrosionsmedium liquid, ore pulp, be widely used in industries such as metallurgy, electric power, mining.
Technical background:
The corrosion resistance pipeline of extensive use have glass-lined steel, steel lining composite pipe etc., but all there is fatal shortcoming in above conduit types, working life is short, fabricating cost is high.
Summary of the invention:
The objective of the invention is to design a kind of novel anti-corrosion pipeline, the problem that this pipeline avoids other pipelines in use to occur, and also easy to make, cost is low, and the steel body portion can be used repeatedly.
This kind pipeline adopts anti-corrosion material to make corresponding tubing, packs in the Steel Sheel, and anticorrosion outer pipe wall and Steel Sheel inwall have certain interval, design suitable vent in appropriate location on the Steel Sheel.According to different usage requirements, the anti-corrosion material kind of cover, making wall thickness and the thickness of steel body pipeline, the rank of flange in selecting.
According to pipeline of the present invention, overlapped anticorrosive, wear-resisting effect in anticorrosion, the steel body case plays pressure-bearing, supporting effect, gas in the vent of steel body is got rid of between cover and the housing, the inner tube of a tyre and the cover tire of interior cover and the similar tire of housing avoid the steel lining composite pipe easily to play drum, the frangible shortcoming of glass-lined steel pipe.
Description of drawings:
Accompanying drawing is the structural representation of straight tube of the present invention, elbow, reducing, and Fig. 1 is straight tube figure, and Fig. 2 is bend pipe figure, and Fig. 3 is reducing figure.
Embodiment:
The suitable vent of design on the Steel Sheel appropriate location, anti-corrosion material is made corresponding tubing, packs in the Steel Sheel, and anticorrosion outer pipe wall and rigid body inner walls have certain interval, and flange facing place hot melt flange extrudes the sealing waterline.
Embodiment 1
Making length with the weldering of φ 98 * 3 steel pipes and DN80PN1.6 flange is 3 meters steel pipe, and the tubing cover that high-molecular polythene is squeezed into φ 89 * 4.5 is entered, two rollovers all over, extrude the sealing waterline.
Embodiment 2
Make elbow with the weldering of 90 ° of elbow steel pipes of φ 98 * 3 punching presses and DN80PN1.6 flange, 90 ° of tubing covers that high-molecular polythene are squeezed into φ 89 * 4.5 are entered, two rollovers all over, extrude the sealing waterline.
Claims (3)
1. pipeline characteristics of the present invention adopt Steel Sheel to strengthen the mechanical strength of corrosion resistant, wearing layer, overcome the shortcoming of conventional composite pipeline lining rapid wear simultaneously, design feature:
