Abstract
A steel-plastic composite hot water pipe comprises a base pipe and an inner lining. The inner lining is placed in the base pipe and close to the inner wall of the base pipe. The base pipe is a steel pipe, the surface roughness of the base pipe is 100-150 Mum and the surface of the base pipe is galvanized. The inner lining is a composite resin layer or a heat-resisting enhanced polyethylene layer; and the thickness of the inner lining is 1.5-2.5mm. The steel-plastic composite hot water pipe is a substitute for a galvanized pipe. A plastic lining method is conducted in a common galvanized pipe and a double-machine coextrusion is adopted for one-time forming and producing an inner lining pipe which is then composite-molded by high temperature and high pressure. The has excellent anticorrosion property and good heat resistant property and avoids scaling; during supply process, the resistance of the fluid is small; the service life of the pipeline is effectively prolonged; the long-time hot water supply of the pipeline is ensured; and the steel-plastic composite hot water pipe can be broadly used for urban construction, oil and coal chemical industry and thermal power generation industry.
Description
Technical field
The utility model relates to a kind of tubing, and especially a kind of steel is moulded compound hot-water line.
Technical background
Hot-water line plays important effect in industrial production or perhaps daily life, hot-water line of today all is to adopt common galvanized pipe steel pipe to connect, zinc-plated malleable cast iron pipe fitting commonly used, the water capacity that this type of pipe fitting flowed out easily is being mingled with the bacterium that rough inwall grows, corrosion causes in the water content of beary metal too high, cause water pollution easily, the healthy while of serious harm human body, pipe interior is anticorrosion poor, easily get rusty, long-term corrosion causes line clogging, uses thereby influence is normal, also there is the bad problem of heat resistance in this class pipeline simultaneously, in use occurs safety problem easily.
The model utility content
The purpose of this utility model is to provide that a kind of effectively to solve pipe interior anticorrosion heat-resisting, and can better optimize the Drinking Water pipe line steel and mould compound hot water pipe special.。
For achieving the above object, the utility model adopts following technological scheme:
A kind of steel is moulded compound hot-water line, comprises parent tube and liner.Described liner places the inside of parent tube and is close to the inwall of parent tube.
Described parent tube is a steel pipe, and its surface roughness is 100-150 μ m; The surface plating of described parent tube is zinc-plated.
Described liner is compound resin layer or heat-resisting enhancement mode polyethylene layer; Described thickness of inner lining is 1.5～2.5mm.
It is a kind of galvanized pipe substitute products that this steel is moulded compound hot-water line, at common galvanized pipe pipe liner molding process, adopts the two-shipper coextruding method, and internal lining pipe is produced in once-through, through the High Temperature High Pressure compound molding.
It is superior that this steel is moulded compound hot-water line antiseptic property, and resistance to heat is good, non-scaling, the course of conveying fluid resistance is little, can effectively increase pipeline working life, guarantee the long-term delivery of pipeline, can be widely used in urban construction, oil coal chemical industry and thermal power generation industry.
Description of drawings
Accompanying drawing 1 is a transverse cross-sectional view of the present utility model;
Accompanying drawing 2 is a longitudinal sectional drawing of the present utility model.
Embodiment
Referring now to accompanying drawing, further describe the utility model.
As shown in Figures 1 and 2, a kind of steel is moulded compound hot-water line, comprises parent tube 1 and liner 2, and parent tube 1 is a steel pipe, and the outer surface of parent tube 1 is covered with one deck zinc, and liner 2 places the inside of parent tube 1 and is close to the inwall of parent tube 1.
The sandblast turbidity test of parent tube 1 are 2.5 grades of Sa, and roughness is 100-150 μ m
The heat resisting temperature of liner 2 is 110 ℃, peeling strength 〉=1.0MPa (100N/cm
2)
Above-described the utility model mode of execution does not constitute the qualification to the utility model protection domain.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
