Abstract
The utility model relates to the super thermal insulation pipe of a kind of composite anti-corrosive, comprises steel pipe, polyurethane insulation coating and polyethylene protective layer, it is characterized in that, be provided with epoxy resin anticorrosive coat between steel pipe and polyurethane insulation coating, and the internal surface of steel pipe is provided with epoxy resin anticorrosive coat.The utility model applies epoxy resin anticorrosive coat respectively at steel pipe inner wall and outer wall, and blocked and got rusty because of oxygen and water and direct contact of steel pipe body, the antiseptic power of enhancing pipeline, extends the working life of pipeline greatly.The utility model is at steel pipe inner wall coating epoxy resin anticorrosive coat simultaneously, and make steel pipe non-scaling, non-nodulating, prevent blocking small sized pipeline or valve, inner wall smooth friction factor is little, and fluid resistance is little, ensures that pipeline is unimpeded.
Description
Technical field
The utility model relates to a kind of heat-insulating pipe, particularly relates to the super thermal insulation pipe of a kind of composite anti-corrosive.
Background technique
Polyurethane foamed thermal-insulating pipe is since polyurethane synthetic material is born, and developed rapidly as a kind of excellent heat-insulating material, its application area is more and more extensive always; Due to its easy construction, energy-saving anti-corrosive Be very effective and be applied to the various pipelines such as heat supply, refrigeration, oil transportation, defeated vapour in large quantities.Its structure is divided into three layers from the inside to surface: working steel tube layer, polyurethane insulation coating and polyethylene protective layer, antiseptic power is limited.Inner-walls of duct is steel pipe body, and outer wall is thermal insulation layer, and this structure easily produces moisture absorption and oxygen uptake corrosion at steel pipe inner and outer surface, makes the various corrosion such as pipeline generation chemical corrosion, electrochemical corrosion, and even rust corrosion, shortens the working life of pipeline.If corrosion failure occurs leak, waste ample resources, bring very large impact to the life of people and production, waste a large amount of manpower and materials simultaneously and be used for reprocessing, maintenance cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of antiseptic power is strong, long service life, the super thermal insulation pipe of not susceptible to plugging composite anti-corrosive.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The super thermal insulation pipe of composite anti-corrosive, comprises steel pipe, polyurethane insulation coating and polyethylene protective layer, is provided with epoxy resin anticorrosive coat between described steel pipe and polyurethane insulation coating, and the internal surface of described steel pipe is provided with epoxy resin anticorrosive coat.
The beneficial effects of the utility model: the utility model applies epoxy resin anticorrosive coat respectively at steel pipe inner wall and outer wall, blocked and got rusty because of oxygen and water and direct contact of steel pipe body, the antiseptic power of enhancing pipeline, extends the working life of pipeline greatly.The utility model is at steel pipe inner wall coating epoxy resin anticorrosive coat simultaneously, and make steel pipe non-scaling, non-nodulating, prevent blocking small sized pipeline or valve, inner wall smooth friction factor is little, and fluid resistance is little, ensures that pipeline is unimpeded.
Accompanying drawing explanation
Fig. 1 is the structural representation of the super thermal insulation pipe of the utility model composite anti-corrosive;
In figure: 1. steel pipe, 2. epoxy resin anticorrosive coat, 3. polyurethane insulation coating, 4. polyethylene protective layer, 5. epoxy resin anticorrosive coat.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
embodiment 1
The super thermal insulation pipe of composite anti-corrosive, comprises steel pipe 1, polyurethane insulation coating 3 and polyethylene protective layer 4, is provided with epoxy resin anticorrosive coat 2 between described steel pipe 1 and polyurethane insulation coating 3, and the internal surface of described steel pipe 1 is provided with epoxy resin anticorrosive coat 5.
Technical solutions of the utility model are: steel tube surface eliminates rust, and------outer wall coating epoxy resin anticorrosive coat---is set with polyethylene containment vessel---polyurethane foam---end-o f-pipe-control to inwall coating epoxy resin anticorrosive coat.Wherein, the work flow of inside and outside wall coating is:------levelling---solidification---cools in spraying in heating.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
