Abstract
The utility model relates to a steel plastic composite pipe with internal external anticorrosive coating, which is formed by an internal steel tube and an external poly hydrocarbon alkene material tube. The internal and external layers of the steel tube are respectively provided with an epoxy resin powder coating layer by coating gluing. The external epoxy resin powder coating layer and the external poly hydrocarbon alkene material tube are connected by the macromolecule bond, which makes the composite pipe having corrosion proof, long service life and high intensity without poison and falling layer. The friction resistance of the internal wall is small. The utility model is tough, wearable and shockproof with strong ability to resist the mechanical damaging.
Description
The utility model relates to a kind of steel-plastic composite pipe with internal and external anti-corrosive coating.
The anti-corrosive steel tube of domestic production at present is general only at steel pipe external form plastic-blasting (epoxy resin), during production fished pipe carried out surface treatment after, single again screwfeed plastic-blasting, manufacturing efficiency is lower, cost is high, and is general corrosion-resistant, heatproof, anti-delamination equivalence fruit.
The purpose of this utility model be to provide a kind of have corrosion-resistant, the life-span long, nontoxic, intensity is high, not delamination, heatproof, little, tough and tensile, wear-resisting, the durable impact of interior type frictional resistance, the strong steel-plastic composite pipe of anti-mechanical deterioration ability.
For achieving the above object, a kind of steel-plastic composite pipe of the present utility model with internal and external anti-corrosive coating, form by inner layer steel pipe and outer polyolefin plastic tube, on steel pipe inner and outer walls, be provided with by spraying bonding epoxy powder coating layer, be connected by polymer binder between epoxy powder coating layer and the outer field polyolefin plastic tube outside.
After adopting such structure, it is anticorrosion to adopt the thermosetting epoxy resin powder coating to carry out at the steel pipe inside and outside wall, and the bonding of itself and steel pipe tube wall is solid and reliable, does not absorb water, oxygen flow not; Outermost surface adopts the polyolefin plastics; by polymer binder and outer wall of steel pipe epoxy resin powder coating tight bond, both can significantly reduce the consumption of epoxy powder coating, reduce cost; make outer wall have excellent toughness again, and make the dual anti-corrosion protection of the outer acquisition of steel pipe.
Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model.
Be of the present utility model a kind of steel-plastic composite pipe that has after internal and external anti-corrosive is coated with shown in Figure 1, form by inner layer steel pipe 1 and outer polyolefin plastic tube 2, inside and outside wall at steel pipe 1 is provided with by spraying bonding epoxy powder coating layer 3,4, is connected by polymer binder between epoxy powder coating layer 4 and the outer field polyolefin plastic tube 2 outside.Make such structure band the utility model can adopt steel tape moulding welding (containing steel strip surface handles), carry out induction heating synchronously, carry out (internal layer rotary spray gun) synchronously inside and outside the epoxy powder coating spraying, outer then polyolefin plastics again, manufacturing efficiency and automaticity height, thereby make and the utlity model has corrosion resistant and lose erosion, life-span is long, nontoxic, the intensity height, not delamination, heatproof, inwall surface friction drag is little, tough and tensile, wear-resisting, shock-resistant, characteristics such as anti-mechanical deterioration ability is strong, both can bright dress also can be geographical, and cost is low, is a kind of NEW TYPE OF COMPOSITE tubing easy to utilize.
