51x55 Bread Tube, 40x60 Bread Tube, 40x65 Bread Tube

1. **Definition and Features of Bread Pipe** - **Definition**: Bread pipe is an irregular tube with a shape resembling a loaf of bread, typically with a bulge in the center and narrower sides. The design of this material is primarily aimed at ensuring a certain level of strength while providing enhanced decorative and functional qualities. - **Features**: - **Aesthetics**: The unique shape of the bread pipe gives it a strong three-dimensional visual appeal, making it more eye-catching than standard square or round tubes, adding a distinctive style to the product. - **Structural Performance**: Due to its special shape, the bulge in the center can effectively dissipate stress when subjected to pressure in certain directions, demonstrating good compressive resistance.

Simultaneously, this shape offers a wider installation surface in applications that require the installation of other components. 2. **51*55 Bread Tube** - **Specs & Structural Details** - **Dimensional Specifications**: The "51*55" typically refers to the approximate cross-sectional dimensions of the bread tube, where 51 could be the smaller dimension (such as the width direction), and 55 could be the larger dimension (such as the height direction).

But which one is the width depends on the actual placement method and usage habit of the pipe. - **Shape Details**: The bulge degree of the bread pipe varies depending on design and usage.

Generally, the middle bulging section may be 5-15mm thicker than the narrow sides, forming a rounded bulging shape. - **Production Process Key Points** - **Forming Process**: Typically, cold bending forming technology is used. The steel strip is first bent through rolling to form a preliminary shaped piece resembling a loaf of bread.

In this process, the shape and arrangement of the rolls must be designed to ensure the pipes gradually assume a centrally bulged form. The steel strip thickness typically ranges from 1.5 to 3mm, with materials such as Q235 carbon structural steel being options. - **Welding and Shaping**: After forming, the edges of the pipes are joined using high-frequency welding. To maintain the shape of the bread tube, shaping is required post-welding, which involves calibration of the pipes through specialized molds or equipment.

Ensure the shape and dimensions of the middle bulge meet the requirements. - **Application Fields** - **Architectural Decoration**: In exterior facade decoration, the 51*55 pipe can be used to create decorative lines such as waistlines and cornice decorations.

Its unique shape enhances the sense of hierarchy and three-dimensionality of buildings. In interior decoration, it can be used to make balusters, decorative partitions, etc., adding an artistic atmosphere to indoor spaces. - **Furniture Manufacturing Industry**: As decorative components for furniture, such as bed headboard frames, leg decorations for tables and chairs, etc.

In furniture with a retro or European style, this bread tube design highlights the elegance and delicacy of the piece more effectively.
