Abstract
The utility model relates to the technical field of pipe fittings, in particular to a novel double-layer pipe fitting. The novel double-layer pipe fitting 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. According to the novel double-layer pipe fitting, the pipe inner layer is arranged on the hollow pipe, the hollow pipe and the pipe inner layer are made of the same materials and are stretched and molded in a one-shot mode, welding is needless, operation is convenient, pipe pressure is improved, and fracture is avoided.
Description
Technical field
The utility model relates to the pipe technology field, especially a kind of novel double-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 double-layer pipe fitting, described a kind of novel double-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 double-layer pipe fitting is provided with inner tube layer 4 at hollow tubular 1, 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 double-layer pipe fitting is provided with inner tube layer 4 at hollow tubular 1, and its hollow tubular 1 and inner tube layer 4 are the moulding of same material one-off drawing, drawing and forming once on drawing die equipment.
