Abstract
The utility model relates to the technical field of pipelines, in particular to a novel inner-layer pipe piece. The novel inner-layer pipe piece is characterized by comprising a hollow pipe, an outer pipe wall, an upper pipe layer head, a pipe inner layer and a lower pipe layer head. The novel inner-layer pipe piece has the advantages that the inner side of the hollow pipe is provided with the pipe inner layer, and the hollow pipe and the pipe inner layer are formed by stretching the same material through one step. The novel inner-layer pipe piece has the advantages that the welding is not needed, the operation is convenient, the pressure of the pipeline is improved and the fracture is prevented.
Description
Technical field
The utility model relates to the pipe technology field, especially a kind of novel evacuated internal layer pipe fitting.
Background technique
The transition of the different bore diameters of its large small pipeline of tradition pipe fitting often needs large-caliber pipe fittings and small-bore pipeline are welded, and not only usually wastes time and energy, and often causes easily fracture, makes pipeline failure.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel evacuated internal layer pipe fitting, described a kind of novel evacuated internal layer pipe fitting, it is characterized in that, comprise: hollow tubular 1, outer tube wall 2, upper pipe layer 3, inner tube layer 4, lower pipe layer 5, described a kind of novel evacuated internal layer pipe fitting is provided with inner tube layer 4 in hollow tubular 1 inboard, and its hollow tubular 1 and inner tube layer 4 are the moulding of same material one-off drawing.
The utility model effect: 1. one-off drawing moulding need not welding; 2. easy-to-operat; 3. the raising pipeline pressure prevents fracture.
Description of drawings
Fig. 1 is the utility model schematic representation;
Wherein: hollow tubular 1, outer tube wall 2, upper pipe layer 3, inner tube layer 4, lower pipe layer 5.
Embodiment
As shown in the figure, described a kind of novel evacuated internal layer pipe fitting, it is characterized in that, comprise: hollow tubular 1, outer tube wall 2, upper pipe layer 3, inner tube layer 4, lower pipe layer 5, described a kind of novel evacuated internal layer pipe fitting, be provided with inner tube layer 4 in hollow tubular 1 inboard, its hollow tubular 1 and inner tube layer 4 are same materials, drawing and forming once on drawing die equipment.
Claims (1)
