Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE pipe technology, and in particular to a PE pipe that can disperse vertical stress. Background Technology
[0002] PE (polyethylene) pipes are used to transport liquids or gases and are commonly found in some energy processing equipment, such as the transport of anaerobic gases. PE pipes are produced in different sizes and lengths according to requirements. During installation, PE pipes require support brackets and fixing brackets to prevent them from sinking and to avoid horizontal displacement. Especially in some large equipment, PE pipes usually need to be installed vertically. Because PE pipes are prone to scaling and become very heavy when clogged, and are also affected by their length or external pressure, support and fixing are particularly important. Traditionally, support structures such as brackets or concrete platforms are set at the bottom of the PE pipe to prevent sinking, and fixing clamps are installed at specific locations on the PE pipe to prevent horizontal displacement. However, due to the thermal expansion and contraction of the pipe, the fixing clamps are usually movable, so they cannot provide support. The stress in the pipe is concentrated at the connection between adjacent pipes or at the bottom of the pipe, which can easily lead to pipe deformation and detachment or bending at the top of the pipe, posing a high risk.
[0003] Therefore, there is an urgent need to design a PE pipe that can disperse vertical stress to solve one or more technical problems that are lacking in the existing technology. Utility Model Content
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a PE pipe that can disperse vertical stress, characterized in that it includes: a pipe body, wherein at least one flange extending away from the pipe body is integrally provided on the outer side of the pipe body, and the extension distance of each flange is 2cm-5cm.
[0005] In a preferred embodiment, the height of the flange is 3cm-5cm.
[0006] In a preferred embodiment, the flange extends horizontally or at a predetermined angle.
[0007] The beneficial effects of this utility model are: by setting a flange on the outside of the pipe body, the geometric shape of the pipe body cross section, and the added flange, the cross section moment of inertia of the pipe in the vertical direction is increased, the strength of the pipe body is improved, stress concentration is effectively dispersed, local stiffness is improved, bending stress is reduced, and the pipe body 10 can be supported in sections to avoid stress concentration, thereby reducing the risk of pipe falling off.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0013] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.
[0014] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0015] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0016] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] like Figures 1-2 As shown, this utility model provides a PE pipe that can disperse vertical stress, characterized in that it includes: a pipe body 10, wherein at least one flange 11 extending away from the pipe body 10 is integrally provided on the outer side of the pipe body 10, and the extension distance of each flange 11 is 2cm-5cm.
[0018] Furthermore, the height of the flange 11 is 3cm-5cm.
[0019] Furthermore, the flange 11 extends in a horizontal direction or at a predetermined angle.
[0020] Specifically, vertical stress refers to the force perpendicular to the ground. During production, a flange 11 is integrally extruded onto the outer side of the pipe body 10. This flange 11 alters the geometry of the pipe body 10's cross-section. The added flange 11 increases the pipe's moment of inertia in the vertical direction. Under gravity, the bending moment is greatest in the middle of the pipe body 10. The flange 11 increases the strength of the pipe body 10, effectively disperses stress concentration, improves local stiffness, and reduces bending stress. Furthermore, the flange 11 allows the fixing clamps to support the pipe body 10 during installation, enabling segmented support of the pipe body 10 and preventing stress concentration. This design reduces the risk of pipe detachment and prevents rupture caused by the pipe body 10. It also avoids conflict with the thermal expansion and contraction of the pipe body 10. The flange 11 has an extension thickness of 2cm-5cm and a height of 3cm-5cm. In this embodiment, a thickness of 2cm and a height of 3cm are preferred. The 2cm thickness helps the fixing clamp support the pipe body 10 via the flange 11 without affecting the thermal expansion and contraction of the pipe body 10, while also reducing cost increases. The 3cm height ensures the strength of the flange 11 and prevents breakage. The extension direction of the flange 11 can be selected as horizontal or at a predetermined angle according to usage requirements, and the cross-sectional shape of the flange 11 is preferably rectangular.
[0021] In summary, by providing a flange 11 on the outside of the pipe body 10, the geometry of the pipe body 10 cross-section is improved. The added flange 11 increases the moment of inertia of the pipe section in the vertical direction, improves the strength of the pipe body 10, effectively disperses stress concentration, improves local stiffness, reduces bending stress, and also allows the pipe body 10 to be supported in sections to avoid stress concentration, thereby reducing the risk of pipe falling off.
[0022] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
