Abstract
The utility model discloses a welded galvanization spiral insulating pipe comprising a pipe body. One side and an opposite side of a cold-rolled steel coil are spirally engaged and enclosed to form the pipe body; a spiral engaging seam is respectively arranged the inner wall and the external wall of the pipe body; the cold-rolled steel coil on two sides of each engaging seam are welded along the engaging seam; a galvanization layer is arranged on the inner wall of the pipe body; a polystyrene insulating layer is mounted on the external wall of the pipe body; and a waterproof layer is arranged on the exterior of the polystyrene insulating layer. A seamless steel pipe is changed into a welded spiral pipe to reduce thickness of the pipe body with the same strength, so cost is reduced; and an original polyurethane foaming insulating layer is changed into the polystyrene insulating layer, so that cost can also be greatly reduced.
Description
Technical field
The utility model relates to a kind of welding zinc-coated spiral thermal insulation pipe.
Background technique
Heating or produce aqueduct used, all will take Insulation.For hot water pipeline, insulation can prevent heat loss.For cold water pipe, insulation can prevent freezing.At present, conventional attemperater structure mostly is seamless straight steel pipe and the polyurethane foamed thermal-insulating layer that is wrapped in seamless straight outer surface of steel tube.For the intensity that improves steel pipe need to strengthen pipe thickness and cause body heavier, be not easy to install, and cost is higher; Although better still price is higher for the polyurethane foamed thermal-insulating layer heat insulation effect outside body.
Model utility content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of lower-cost welding zinc-coated spiral thermal insulation pipe rational in infrastructure is provided.
For achieving the above object, the technical solution of the utility model provides a kind of welding zinc-coated spiral thermal insulation pipe, described welding zinc-coated spiral thermal insulation pipe comprises body, described body is formed to enclose to connect with its opposite side screw occlusion on one side by cold-rolled steel coils, on the inner and outer wall of described body, form two spiral helicine interlock seams, the cold-rolled steel coils of described interlock seam both sides is along interlock seam welding; Described inboard wall of tube body is provided with zinc coat, and described tube wall is provided with polystyrene heat-preservation layer, and described polystyrene heat-preservation layer is provided with watertightness barrier outward.Can under the prerequisite that reaches same intensity, reduce the thickness of body by seamless steel pipe being replaced with to welding volute, and then reduce costs, original polyurethane foamed thermal-insulating layer be replaced with to polystyrene heat-preservation layer and also can greatly reduce costs.
As preferably, cold-rolled steel coils screw occlusion encloses and connects produced convex tendon and all protrude to outer surface of tube body.Such design is the further optimization to scheme.
As preferably, described zinc layer is zinc coat, and described galvanized layer thickness is greater than or equal to 0.06mm.Such design is the further optimization to scheme.
As preferably, described polystyrene heat-preservation layer is bonding with tube wall and watertightness barrier respectively by tackiness agent.Such design is the further optimization to scheme.
Advantage of the present utility model and beneficial effect are: the thickness that can reduce body by seamless steel pipe being replaced with to welding volute under the prerequisite that reaches same intensity, and then reduce costs, original polyurethane foamed thermal-insulating layer is replaced with to polystyrene heat-preservation layer and also can greatly reduce costs.
Accompanying drawing explanation

Fig. 2 is A place enlarged diagram in Fig. 1.
In figure: 1, body; 2, zinc layer; 3, polystyrene heat-preservation layer; 4, watertightness barrier; 5, convex tendon; 6, tackiness agent.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of welding zinc-coated spiral thermal insulation pipe, described welding zinc-coated spiral thermal insulation pipe comprises body 1, described body 1 is formed to enclose to connect with its opposite side screw occlusion on one side by cold-rolled steel coils, on the inner and outer wall of described body 1, form two spiral helicine interlock seams, the cold-rolled steel coils of described interlock seam both sides is along interlock seam welding; Described body 1 inwall is provided with zinc layer 2, and described body 1 outer wall is provided with polystyrene heat-preservation layer 3, the outer watertightness barrier 4 that is provided with of described polystyrene heat-preservation layer 3.
Cold-rolled steel coils screw occlusion encloses and connects produced convex tendon 5 all to body 1 outer surface protrusion.
Described zinc layer 2 is zinc coat, and described galvanized layer thickness is greater than or equal to 0.06mm.
Described polystyrene heat-preservation layer 3 is bonding with body 1 outer wall and watertightness barrier 4 respectively by tackiness agent 6.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
