Abstract
The utility model provides a pair of novel compound steel pipes is moulded to lining, including parent tube and inside lining plastic tubing. The parent tube be the steel pipe, the steel pipe outer wall be provided with the anticorrosive coating, inside lining plastic tubing from interior to exterior be antibiotic layer, based bulk layer and heat preservation in proper order. The steel pipe is as the outer wall of plastics tubular product, can not only prevent that plastics from too early by the oxidation, but also can prevent that plastics are by external world's effect damage, the steel pipe outer wall scribbles the anticorrosive coating, can prevent the steel pipe and corroded owing to expose for a long time, the heat preservation is the polyurethane foam plastic layer, can completely cut off by wrap -around based bulk layer thermal distribute with the external erosion that freezes, antibiotic layer have to microorganisms such as the bacterium in the rivers, mould can be effectively the antibacterial or function of disinfecting. The technical scheme of the utility model simple structure, it is convenient to make, have anticorrosive, keep warm, hinder oxygen, antiseptic function, but the water feeding pipe system that the wide application was construct in industry and residential houses.
Description
Technical field
This utility model relates to waterworks structure tubing technical field, particularly relates to a kind of novel plastic lining composite steel pipe.
Background technology
People's daily life water both is from public water supply pipe, feedwater piping is the primary supply channel of our daily water consumption, nowadays feedwater piping is plastic lining composite steel pipe mostly, this steel pipe is with zinc-plated seamless steel pipe, welded still pipe for base tube, after inwall removes weldering muscle, it is lining into the plastic pipe isometrical with in galvanized pipe, such as polyvinyl piping materials (PE pipe) or three type random copolymerization polypropylene pipes (PP-R pipe), last pressurized, heated certain time aftershaping.
After existing lining plastic compound steel pipe range uses a period of time, plastic tube wall inwall can adhere to or cooperating microorganisms, and when water flow in pipeline is slow or water is temporarily retained, antibacterial is attached to tube wall, breeding through a period of time can form one layer of Mycoderma, has a strong impact on the safe drinking water of people.Meanwhile, plastic pipe all has and oozes oxygen, and along with the oxygen infiltration amount raising plastic pipe of temperature increases, causes plastics accelerated ageing, reduce the service life of plastic pipe.PP-R is managed, under subzero ten degree of temperature below environment, there is serious cold brittleness, it is easy to occur that tubing ftractures.
Utility model content
The purpose of this utility model is in that to provide the novel plastic lining composite steel pipe of a kind of anticorrosion, antibacterial, resistance oxygen, insulation, to solve problems of the prior art.
The novel plastic lining composite steel pipe of one that this utility model provides, including: base tube and inner lining plastic tube.
Described base tube is steel pipe；
Described outer wall of steel pipe is provided with anticorrosive coat；
Described inner lining plastic tube is followed successively by antibiotic layer, body layer and heat-insulation layer from the inside to the outside.
Further, described anticorrosive coat material is titanium nano modification anticorrosive paint or polyethylene coating；
Further, described body layer is PP-R pipe or PE pipe；
Further, the mode that described antibiotic layer, body layer and heat-insulation layer are pressurizeed by hot melt is combined；
Further, described heat-insulation layer is the polyurethane foam plastics layer being coated on outside described body layer；
Further, described antibiotic layer adds plastic antimicrobial agent in the course of processing and is prepared from；Described antibacterial is inorganic antiseptic or organic antibacterial agent or natural antibacterial agent；
Further, described inorganic antiseptic is AgNO3Or Ag, Cu, Zn；Described organic antibacterial agent is vanillin, ethyl vanillin aldehyde compound；Described natural antibacterial agent is chitin, mustard or Wasabia japonic (Euterma Wasabi)；
Further, the thickness of described steel pipe is 8-12mm；Described anticorrosive coat thickness is 1-3mm；Described plastic lining tube thickness is 2-5mm.
The beneficial effects of the utility model are:
This utility model provide the novel plastic lining composite steel pipe of one, have anticorrosion, antibacterial, resistance oxygen, insulation effect, effectively increase the service life of pipeline, it is ensured that the safety of people's daily water consumption.Specifically, this utility model is the coalition of steel pipe and plastic pipe, and steel pipe is as the outer wall of plastic pipe, there is significantly high mechanical strength and hardness, gas, liquid etc. can not only play blocking effect to external world, it is prevented that plastics are oxidized too early, and can also prevent plastics from being damaged by external influence；Outer wall of steel pipe scribbles anticorrosive coat, and described anticorrosive coat material is titanium nano modification anticorrosive paint or polyethylene coating, and steel pipe can be prevented to be corroded owing to exposing for a long time；Heat-insulation layer is polyurethane foam plastics layer, owing to foamed plastic layer has a foaming pore that is intensive and that be immediately adjacent to each other, thus can completely cut off distributing and the erosion of extraneous frost of the body layer heat that is wrapped by；Antibiotic layer is inorganic antiseptic or organic antibacterial agent or natural antibacterial agent adds in plastic matrix and is prepared from, and due to antibiotic layer directly and water stream contacts, having can effectively antibacterial or sterilizing function to microorganisms such as the antibacterial in current, mycetes.
