Abstract
The utility model discloses a compound pipe keeps warm, including steel pipe and nonrust steel pipe layer, it is used for heat retaining polyurethane insulation layer to be equipped with between steel pipe and the nonrust steel pipe layer, the inboard on stainless steel layer is for being used for anticorrosive modified epoxide resin anticorrosive coating, the inboard of modified epoxide resin anticorrosive coating is high temperature resistant layer, the outside of steel pipe is for being used for antiseptic and rustproof polyethylene powder coating anticorrosive coating, the antibiotic layer of the outside for adding antiseptic of polyethylene powder coating anticorrosive coating. This product not only can insulate against heat in high -efficient heat preservation, improves heat utilization efficiency, can effectively prevent multiplying of bacterium simultaneously, improves the resistance to corrosion of steel pipe and nonrust steel pipe, prolongs long pipeline's life, reduces the use and the cost of overhaul, has wide application prospect.
Description
Technical field
The utility model relates to a kind of pipeline material, is specifically related to a kind of composite insulating pipe.
Background technique
The supply line of attemperater as hot water can be used in a large number in domestic water and housing heating.In order to ensure the efficiency of supply of hot water and reduce energy consumption, attemperater needs to have preferably thermal and insulating performance, to reduce the heat loss of hot water in heat supply water pipe, improves heating efficiency, reduces the cost of heat supply.
Because heat supply water pipe is mostly in comparatively moist environment, easily there is the problem of water pipe corrosion, the working life of heat supply water pipe is restricted, makes the maintenance cost of heat supply water pipe increase simultaneously, be unfavorable for the cost reducing heat supply.And after supplying hot water pipe Long-Time Service, pipeline external and the medium contact such as air, soil, get rusty easily and breed bacteria, not only cause environmental pollution, and causing piping failure to leak, waste great lot of water resources, affects pipeline whole service life, reprocess frequent, amount of maintenance is large, and maintenance cost is high.
Summary of the invention
The utility model, for the deficiency of existing thermal insulation pipe, provides a kind of long service life, is not easily corroded, high insulating effect composite insulating pipe.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of composite insulating pipe, comprise steel pipe and stainless steel tube layer, the polyurethane insulation coating for being incubated is provided with between described steel pipe and stainless steel tube layer, the inner side of described stainless steel lining is for corrosion-resistant modified epoxy anticorrosive coat, the inner side of described modified epoxy anticorrosive coat is high-temperature-resistant layer, the outside of described steel pipe is for antiseptic and rustproof polyethylene powder coating anticorrosive coat, and the outside of described polyethylene powder coating anticorrosive coat is the antibiotic layer adding antimicrobial agent.
Described, the thickness of polyurethane insulation coating is 2-6mm.
Described, the thickness of modified epoxy anticorrosive coat is 0.2-0.3mm.
Described, high-temperature-resistant layer is modified, high temperature resistant epoxy resin, and thickness is 0.1-0.25mm.
Described, the thickness of polyethylene powder coating anticorrosive coat is 0.15-0.3mm.
Described, the thickness adding the antibiotic layer of antimicrobial agent is 0.2-0.3mm.
Described, the seamless steel pipe of steel pipe to be thickness be 3-5mm.
The beneficial effects of the utility model: the utility model sets up different coatings in the outside of composite pipe and inner side, can not only be high-efficiency insulated heat insulation, improve heat utilization ratio, can effectively prevent growing of bacterium simultaneously, improve the anti-corrosion capacity of steel pipe and Stainless Steel Tube, extend the working life of pipeline, reduce and use and the cost of overhaul, have broad application prospects.
