The drinking water delivery pipe with an epoxy polyurethane coating is characterized in innocuity, excellent adsorption, flexibility, wearability, chlorine penetration resistance, and convenient construction.
Description
Technical field
The utility model relates to a kind of potable water transfer line, and particularly a kind of potable water delivery pipe that has the epoxy polyurethane coating is a kind of underground potable water transfer line that is embedded in.
Background technique
At present, for prolonging the service life of the buried steel pipe line of carrying potable water, need carry out anticorrosion to steel pipe.Anticorrosion main employing slush or non-toxic coatings in the buried steel pipe, the epoxide coal bituminous anticorrosive paint of outer anticorrosion employing.Existing slush and non-toxic coatings hardness height, poor toughness in lifting, transportation process, very easily cause the damage of coating, lose antiseptic effect.Outer anticorrosion epoxide coal bituminous anticorrosive paint just needs to twine glass cloth in order to strengthen intensity, to increase toughness, has increased the cost cost, and has very easily influenced the anti-corrosive properties of epoxide coal bituminous anticorrosive paint.
The model utility content
The purpose of this utility model is: a kind of potable water delivery pipe that has the epoxy polyurethane coating is provided, and it is not contaminated to make the potable water conveying steel pipe have nontoxic, good adhesion, pliability, wear resistance, resistance of chloride ion penetration, water quality; The protection steel pipe can not be damaged in construction and installation, guarantees that its pipeline is long-term, safe operation; Prevent that chlorion etc. in the underground water is to the corrosion penetration of coating.
The technical solution adopted in the utility model is:
A kind of potable water delivery pipe that has the epoxy polyurethane coating mainly comprises steel pipe, and there is welding section at the steel pipe two ends, it is characterized in that the internal surface of welding section has inorganic zinc silicate can weld internal layer, and the outer surface of welding section has inorganic zinc silicate can weld skin.At the internal surface of steel pipe drinking water pipeline protection epoxy polyurethane internal layer is arranged, epoxy zinc rich primer skin and epoxy polyurethane skin are arranged successively at the outer surface of steel pipe.The internal diameter of the long 9～12m of steel pipe, steel pipe is the wall thickness 16～25mm of 1000～2000mm, steel pipe.Each long 100～150mm of the every end of described welding section.The thickness that inorganic zinc silicate can weld internal layer is 0.04～0.08mm, and it is 0.04～0.08mm that inorganic zinc silicate can weld outer field thickness.The thickness of epoxy polyurethane internal layer is 0.5～1.0mm, and the outer field thickness of epoxy zinc rich primer is 0.06～0.10mm, and the outer field thickness of epoxy polyurethane is 0.5～1.0mm.
The potable water delivery pipe that has the epoxy polyurethane coating, the internal diameter that it is characterized in that the long 12m of steel pipe, pipe is 1500mm, wall thickness 20mm, welding segment length 120mm, the thickness that inorganic zinc silicate can weld internal layer is 0.06mm, it is 0.07mm that inorganic zinc silicate can weld outer field thickness, the drinking water pipeline protection is 0.6mm with layer thickness in the epoxy polyurethane, the epoxy zinc rich primer skin
Thickness be 0.07mm, the outer field thickness of epoxy micaceous iron intermediate coat is 0.07mm, the outer field thickness of epoxy polyurethane is 0.8.
The potable water delivery pipe manufacture process that has the epoxy polyurethane coating is as follows: consult accompanying drawing.
With steel pipe 1 inner and outer surface derusting by sandblasting, internal surface spraying drinking water pipeline protection epoxy polyurethane 5 at steel pipe 1, can weld internal layer 3 at reservation welding section 2 internal surfaces spraying inorganic zinc silicate, outer surface at steel pipe 1 sprays epoxy zinc rich primer skin 6, epoxy polyurethane skin 7 successively, can weld internal layer 4 at reservation welding section 2 outer surfaces spraying inorganic zinc silicate.Should manage at the scene to connect and make pipeline.
The utility model beneficial effect compared with prior art:
1, the potable water delivery pipe that has the epoxy polyurethane coating; interior barrier coating uses the good nontoxic coating of drinking water pipeline epoxy polyurethane of pliability; both protected steel pipe not to be subjected to burn into water quality not contaminated; can protect steel pipe again and in construction and installation, not be damaged, thereby guarantee that its pipeline is long-term, safe operation.
2, outer anticorrosion barrier coating can guarantee that pipeline uses for a long time under the environment of underground corrosion, prevent that effectively chlorion etc. in the underground water is to the corrosion penetration of coating.
3, reserve the inner and outer surface coating inorganic zinc silicate weldable coating layer of welding section, can prevent to reserve welding section before pipeline welds repaired mouth further corrodes, the welding slag that produces during the pipeline welding is easy to be cleaned out, thereby improves the quality of pipeline repaired mouth, makes pipeline keep good antiseptic effect.
