Abstract
The utility model provides a large-caliber framework pipe and a pipe adopting large-caliber framework pipes and a polythene winding structure wall. The large-caliber framework pipe comprises a framework pipe body and a polythene layer totally coating the circumferential wall surface of the framework pipe body; and the diameter of the framework pipe body ranges between DN 90 mm and DN 150 mm. The pipe provided with the large-caliber framework pipes and the polythene winding structure wall comprises a polyethylene pipe wall of the inner layer and the large-caliber framework pipes wound outside the polyethylene pipe wall of the inner layer, wherein each large-caliber framework pipe comprises a framework pipe body and a polythene layer totally coating the circumferential wall surface of the framework pipe body, and the diameter of each framework pipe body ranges between DN 90 mm and DN 150 mm. According to the large-caliber framework pipe and the pipe provided with the large-caliber framework pipes and the polythene winding structure wall, raw materials can be saved, so that the cost is saved. Moreover, a product is light in weight and higher in production efficiency.
Description
Technical field
The utility model relates to a kind of polyethylene spirally enwound structure-wall tubular product, specifically a kind of tube of large aperture framework and wall tube of large aperture framework-tube polyethylene winding structure.
Background technique
In high density polyethylene (HDPE) winding structure wall pipe production process, at first be wound around inner layer polyethylene (HDPE) to form Flat belt on mould, be wound around subsequently the skeleton pipe outside Flat belt, described skeleton pipe is coated polypropylene (PP) skeleton pipe and formed by outer layer polyethylene.Adopt existing equipment when forming structure-wall pipe material, the maximum caliber of skeleton pipe can reach DN90mm, the outer layer polyethylene that the described skeleton pipe outside coats is generally that the polyethylene of radian between 180 ° ~ 230 ° coats band, after being wrapped in the skeleton pipe outside Flat belt, described inner layer polyethylene and described outer layer polyethylene can seal described skeleton pipe fully, thereby provide corresponding ring stiffness for structure-wall pipe material.
Along with the increase of structure-wall pipe material bore, its desired ring stiffness requires also to improve gradually.In order to satisfy the ring stiffness requirement of heavy caliber structure-wall pipe material, generally take to increase the method in skeleton mouth of pipe footpath, but in prior art, the width of the outer layer polyethylene of skeleton pipe outer cladding can not be along with the increase in skeleton mouth of pipe footpath and is increased, thereby affect the welding between skeleton pipe and Flat belt, also make the external dew of polypropylene tube of the tube of large aperture framework that is wound in Flat belt.If do not increase the bore of skeleton pipe, needing increases the winding number of plies of inner layer polyethylene so that the ring stiffness of structure-wall pipe material reaches requirement, and the winding number of plies of increase inner layer polyethylene not only causes raw materials consumption many, and product is heavy, and manufacturing efficiency is low.
The model utility content
One of the purpose of this utility model is to provide a kind of tube of large aperture framework, and is many to solve the raw materials consumption that exists in wall tube of large aperture framework-tube polyethylene winding structure production, the technical problem that product is heavy.
Two of the purpose of this utility model is to provide the wall tube of large aperture framework-tube polyethylene winding structure that a kind of cost of production is low, product weight is light, manufacturing efficiency is high and ring stiffness is high.
The utility model is achieved in that
Tube of large aperture framework forms by the skeleton body and with the full polyethylene layer that coats of described skeleton body periphery wall, and described skeleton pipe diameter is DN90mm ~ DN150mm.
Wall tube of large aperture framework-tube polyethylene winding structure, by the inner layer polyethylene tube wall and be wrapped in the outer tube of large aperture framework of described inner layer polyethylene tube wall and consist of, described tube of large aperture framework forms by the skeleton body and with the full polyethylene layer that coats of described skeleton body periphery wall, and described skeleton pipe diameter is DN90mm ~ DN150mm.
The bore of the skeleton body in the utility model is DN90mm ~ DN150mm, and outer layer polyethylene coats described skeleton pipe fully, therefore, the skeleton pipe that is coated with outer layer polyethylene is wrapped in rear formed heavy caliber structure-wall pipe material on Flat belt, its ring stiffness can reach designing requirement.Because the tubing of this structure is not to satisfy ring stiffness by the winding number of plies that increases inner layer polyethylene to require, therefore, the utility model not only can be saved raw material, thereby saves cost, and the weight of product is lighter, and the manufacturing efficiency of product is higher.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, polyethylene layer, 2, the inner layer polyethylene tube wall, 3, the skeleton body, 4, socket, 5, bellmouth, 6, electric heating element.
Embodiment
As shown in Figure 1, the utility model comprises inner layer polyethylene tube wall 2 and is wrapped in the outer tube of large aperture framework of inner layer polyethylene tube wall 2, described tube of large aperture framework comprises skeleton body 3 and the full polyethylene layer that coats 1 of described skeleton body 3 periphery walls is formed, polyethylene layer 1 coats skeleton body 3 fully, make skeleton body 3 be wrapped in inner layer polyethylene tube wall 2(or claim Flat belt) upper after, skeleton body 3 can not expose, the welding quality is good, thereby can guarantee the ring stiffness requirement of high density polyethylene (HDPE) winding structure wall pipe.
The pipe diameter of skeleton described in the present embodiment is DN90mm ~ DN150mm, and bigbore skeleton pipe like this be used for to be made the high density polyethylene (HDPE) winding structure wall pipe of heavy caliber (for example DN1500mm and more than).
One end of above-mentioned wall tube of large aperture framework-tube polyethylene winding structure is provided with bellmouth 5, one end is provided with socket 4, imbed a circle electric heating element 6 on the inwall of bellmouth 5, particularly, electric heating element 6 can form by crooked the structure that is snakelike shape by the H65 zinc-copper silk that diameter is 2mm, and the two ends of electric heating element 6 is stretched out bellmouth 5 inwalls.When two sections tubing connect, make two sections on tubing bellmouth and the end face of socket closely cooperate, the electric heating element of heating in bellmouth makes the polyethylene interdiffusion mutually on bellmouth and socket, the cooling connection that can complete two sections tubing afterwards.
Claims (2)
1. a tube of large aperture framework, is characterized in that, forms by the skeleton body and with the full polyethylene layer that coats of described skeleton body periphery wall, and described skeleton pipe diameter is DN90mm ~ DN150mm.
2. wall tube of large aperture framework-tube polyethylene winding structure, by the inner layer polyethylene tube wall and be wrapped in the outer tube of large aperture framework of described inner layer polyethylene tube wall and consist of, it is characterized in that, described tube of large aperture framework forms by the skeleton body and with the full polyethylene layer that coats of described skeleton body periphery wall, and described skeleton pipe diameter is DN90mm ~ DN150mm.
