U-Bolt for Ship Piping

Abstract

The present invention relates to a U-bolt for ship piping, and more specifically, to a U-bolt used to fix ship piping in which the inner surface of the U-bolt is formed flat and a rubber coating material is applied to the outer surface of the U-bolt, thereby increasing the bonding strength between the ship piping and the U-bolt, and also preventing vibration of the piping by having the rubber coating material act as a cushion between the ship piping and the U-bolt. According to the present invention, a U-bolt for ship piping is provided, characterized in that the inner surface of the U-bolt (10) in contact with the ship piping (20) is formed flat.

Description

Technology Field

[0001] The present invention relates to a U-bolt for ship piping, and more specifically, to a U-bolt in which the inner surface of the U-bolt, which is coated with a rubber coating material on its outer circumference, is formed flat, thereby not only increasing the bonding strength between the ship piping and the U-bolt but also minimizing vibration of the piping by having the rubber coating material act as a cushion between the ship piping and the U-bolt. Background Technology

[0002] In general, U-bolts used to secure ship piping have a circular surface as shown in Fig. 1, and a rubber coating is applied to the outer circumference. Conventional U-bolts like the above have a circular surface, so the contact surface between the pipe and the U-bolt is close to line contact. In such cases of line contact, the bonding strength between the pipe and the U-bolt is reduced, and when fluid flows through the pipe, vibration occurs, which weakens the bonding strength between the pipe and the U-bolt. The problem to be solved

[0003] The purpose of this invention is to resolve the aforementioned problems of the prior art. By forming the inner surface of the U-bolt that contacts the pipe as a flat plane and covering its outer periphery with a rubber coating material, the contact surface between the pipe and the U-bolt is enlarged, thereby increasing the bonding strength between the pipe and the U-bolt. Furthermore, the rubber coating material acts as a cushion to minimize vibrations occurring between the pipe and the U-bolt, and consequently, the invention aims to provide a U-bolt for marine piping that can extend the lifespan of the pipe. Effects of the invention

[0005] As such, the present invention forms the inner surface of the U-bolt flat and coats the outer surface with a rubber coating material, thereby maximizing the contact area between the pipe and the U-bolt to increase the bonding strength between the pipe and the U-bolt. Furthermore, the rubber coating material minimizes vibrations generated in the pipe, and if a Teflon coating layer is formed, it provides a cushioning effect and a low coefficient of friction, allowing it to respond to minute vibrations in the pipe.

[0007] In a conventional U-bolt (10) for ship piping, which has a rubber coating material (30) covering its outer circumference, the inner surface of the U-bolt (10) that contacts the ship piping (20) is formed as a flat surface. In the above, a Teflon coating layer (40) is formed on the flat portion of the inner surface of the U-bolt (10). The following is a detailed description with reference to the attached drawings so that a person skilled in the art to which the present invention belongs can easily implement the technical concept of the present invention. FIG. 1 is a perspective view illustrating a conventional U-bolt, FIG. 2 is a perspective view illustrating the entire invention, FIG. 3 is a cross-sectional view illustrating the entire invention, FIG. 4a or 4b is a state diagram illustrating the usage state of the invention, FIG. 5a or 5b is a state diagram and cross-sectional view illustrating the Teflon coating state in the invention. First, the inner surface of the U-bolt (10) that contacts the pipe (20) is formed as a flat surface to maximize the contact area between the pipe (20) and the U-bolt (10). Then, a rubber coating material (30) is applied to the entire outer circumference of the U-bolt (10). The reason for applying the rubber coating material (30) in this manner is to ensure that the rubber coating material (30) acts as a cushion between the U-bolt (10) and the pipe (20) while simultaneously minimizing vibration of the pipe (20). A Teflon coating layer (40) may be formed on the rubber coating material (30) coated as described above. When forming, the Teflon coating layer (40) is formed only on the flat portion of the inner surface of the U-bolt (10). The reason for forming the Teflon coating layer (40) is that while the rubber coating material (30) has only elasticity and thus has a high coefficient of friction, forming the Teflon coating layer (40) on top of the rubber coating material (30) allows for elasticity to be maintained while simultaneously reducing the coefficient of friction. In other words, when the pipe (20) vibrates, the vibration is minimized by the rubber coating material (30), and at the same time, the U-bolt (10) slides on the pipe (20) by the Teflon coating layer (40), allowing it to respond to the minute vibrations of the pipe (20), thereby preventing damage to the pipe (20).
