Abstract
A kind of high-performance mechanical steel pipe of the present utility model; comprise high-performance mechanical steel pipe matrix; the outer wall of described high-performance mechanical steel pipe matrix is enclosed with metallic zinc coating; metallic zinc coating scribbles modified asphalt layer outward; modified asphalt layer is wound with glass fabric layer outward; glass fabric layer is outside equipped with filling polyurethane layer, is enclosed with polyethylene protective layer outside filling polyurethane layer.As optimization, described metallic zinc coating thickness is 40-100 μ m, and described modified asphalt layer coating thickness is 100-200 μ m, and the thickness of polyethylene protective layer is 300-350 μ m.High-performance mechanical steel pipe of the present utility model includes five layers of coating; the high-performance mechanical steel pipe of this coating structure has good corrosion resistance and heat insulating ability under wet environment; waterproof protecting layer outward appearance is clean and tidy, it is even, closely knit to cover, and its protection period is long, antiseptic property good.
Description
Technical field
The utility model belongs to machinery with metal tube manufacture field, is specifically related to a kind of high-performance mechanical steel pipe.
Background technique
High-performance mechanical steel pipe has the essence of iron, the performance of steel, and antiseptic property excellence, ductility are good, good sealing effect, install simple and easy, be mainly used in municipal administration, industrial and mining enterprise's feedwater, gas transmission, oil transportation etc.General high-performance mechanical steel pipe is to add sealing corrosion protective covering as composite protective system using zinc protective layer, and this is the protective system that a kind of sacrificial anode adds cathodic protection, has advantages of anticorrosion year limit for length, is used widely all over the world.But, in pipe installation process, being subject to sometimes river and stopping, riverbed is established and crossed over to the high-performance mechanical steel pipe that in the past conventionally adopts above-mentioned protection system along the river bed, and this high-performance mechanical steel pipe is subject to the impact of current and sandstone for a long time, and corrosion is very fast.
Summary of the invention
The purpose of this utility model is to overcome above shortcoming, and a kind of high-performance mechanical steel pipe can with stronger waterproof anti-corrosion performance is provided.
High-performance mechanical steel pipe of the present utility model; comprise high-performance mechanical steel pipe matrix; the outer wall of described high-performance mechanical steel pipe matrix is enclosed with metallic zinc coating; metallic zinc coating scribbles modified asphalt layer outward; modified asphalt layer is wound with glass fabric layer outward; glass fabric layer is outside equipped with filling polyurethane layer, is enclosed with polyethylene protective layer outside filling polyurethane layer.
As optimization, described metallic zinc coating thickness is 40-100 μ m, and described modified asphalt layer coating thickness is 100-200 μ m, and the thickness of polyethylene protective layer is 300-350 μ m.
High-performance mechanical steel pipe of the present utility model includes five layers of coating; the high-performance mechanical steel pipe of this coating structure has good corrosion resistance and heat insulating ability under wet environment; waterproof protecting layer outward appearance is clean and tidy, it is even, closely knit to cover, and its protection period is long, antiseptic property good.
