Description

{Insulated pipe of Vessel}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulation piping for marine use.

In general, insulation refers to an electrical insulating material that blocks the transmission of electricity, or an insulation material that blocks the transmission of heat. In the work area requiring fire protection from the ship's residence area, engine room, etc., And insulation may be referred to as an insulation structure.

Such an insulation structure may be particularly important for a liquefied natural gas carrier that stores or transports liquefied natural gas liquefied at cryogenic temperatures.

These liquefied natural gas carriers have mostly cargo holds that can store liquefied natural gas. These cargo holds a cryogenic material to store liquefied natural gas with medium pressure above atmospheric pressure and a boiling temperature of minus 160 ° C For example, it is required to be made of aluminum alloy, stainless steel, 35% nickel steel, etc., and it is required to design a structure capable of coping with thermal stress and heat shrinkage and to install an insulation structure to prevent heat penetration.

In addition, noise problems frequently occur in piping connected to various equipments such as pumps and valves of ships and special types of vessels. In order to solve such a noise problem, an insulation structure may be adopted.

However, the ability of the insulation structure to block noise is closely related to the insulation material, thickness, and weight of the piping. To achieve a high level of noise isolation, the thickness of the insulation must be either too thick or excessively thick.

However, in the case of special types of vessels, it is difficult to apply thick insulation because of the insufficient distance between the piping and piping, or the narrow space between the piping and other members such as electric trays, HVAC ducts, ship members, etc., Problems also frequently occur, and there is a problem that heavy insulation is difficult to install.

An object of the present invention is to provide an insulation piping for a ship capable of shielding noise.

In particular, it is an object of the present invention to provide an insulation piping for marine vessels that is light in weight and has an improved soundproofing ability while minimizing the thickness of insulation.

The present invention provides an insulation piping for ships.

First, an insulation piping for a ship according to a preferred embodiment of the present invention includes a piping body; And an insulation member surrounding the pipe body at an outer periphery of the pipe body to insulate the pipe body, wherein an air gap may be formed between an outer periphery of the pipe body and an inner periphery of the insulation member .

The vibration insulating member may further include a vibration insulating member disposed between the outer circumference of the pipe body and the inner circumference of the insulating member to block a solid sound transmitted from the pipe body to the insulating member.

More preferably, the vibration insulating member is provided with a rubber ring wound around the outer periphery of the pipe body, and the rubber ring may be provided in contact with the inner circumference of the insulating member.

More preferably, the insulating member may be formed of E glass fiber.

More preferably, the E glass fiber may have a thickness of 15 mm or more and 40 mm or less.

According to the present invention, it is possible to improve the noise shielding ability of the insulation pipe for marine use.

Further, it is possible to improve the noise shielding ability while reducing the weight of the piping having the same thickness.

That is, the thickness of the pipe is minimized, and the weight reduction and the noise shielding ability can be improved.

In addition, there is an effect that corrosion due to condensation can be prevented by the air gap inserted into the piping.

In order to facilitate an understanding of the description of the embodiments of the present invention, elements denoted by the same reference numerals in the accompanying drawings are the same element, and among the elements having the same function in each embodiment, Respectively.

Further, in order to clarify the gist of the present invention, a description of elements and techniques well known in the prior art will be omitted, and the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood, however, that the spirit and scope of the present invention are not limited to the embodiments shown, but may be suggested by those skilled in the art in other forms, additions, or alternatives, .

1, the insulated pipeline for a ship according to the preferred embodiment of the present invention includes a piping body 110 and a pipe body 110 surrounding the piping body 110, And an air gap may be formed between the outer circumference of the pipe body 110 and the inner circumference of the insulating member 120. [

Specifically, the piping body 110 may be provided with a hollow tube having an inner space. For example, the fluid may flow through the hollow interior space 111.

At this time, the kind of fluid flowing through the internal space 111 of the piping body 110 is not limited by the present invention.

The insulation member 120 is spaced a predetermined distance from the outer circumference of the pipe body 110 and the insulation member 120 is disposed to surround the pipe body 110 from the outer circumference of the pipe body 110 .

At this time, the piping body 110 and the insulation member 120 are separated from each other, so that a space 130 is formed between the outer surface of the piping body 110 and the inner surface of the insulation member 120. The spacing space 130 is provided with an air gap.

The air gap performs an insulation function as well as an insulation function. The air gap formed between the piping body 110 and the insulating member 120 reduces the thickness and weight of the entire piping for the ship and creates an effect of preventing corrosion due to condensation.

The insulating member 120 is disposed outside the air gap, and may preferably be made of E Glass fiber. E Glass fiber is one of the composition of glass fiber which is used as base material of copper clad laminate. It is low alkaline for electric insulation and easy to manufacture and handle, so it is used as glass fiber of copper clad laminate.

The composition had 54.3% of SiO2, 15.0% of Al2O3, 17.3% of CaO, 4.7% of MgO, 8.0% of B2O3, 0.2% of R2O, 0.2% of Fe2O3 and 0.4% of other components and had a softening temperature of 840 캜, specific gravity of 2.54, dielectric constant of 7.23, , And a thermal expansion coefficient of 4.52 10 -6 mm / mm ° C.

Such E Glass fiber has high density and is easy to maintain its shape without attaching a separate metal plate, and has an effect of performing a sound insulation function.

However, this is a preferred embodiment of the present invention, and the type of the insulating member 120 is not limited to the present invention, but may be suitably modified and applied by those skilled in the art.

Fig. 2 shows I-I 'of Fig. The vibration insulating member 140 is provided in the space 130 between the outer surface of the pipe body 110 and the inner surface of the insulating member 120.

The vibration insulating member 140 is disposed in the spacing space 130 and serves to support a sound insulation function of the air gap. That is, the vibration insulating member 140 provided to contact the outer surface of the piping body 110 and the inner surface of the insulating member 120 maximizes the sound insulation performance in addition to the air gap.

When the vibration insulating member 140 is provided as a rubber ring, the solid sound transmitted from the piping body 110 to the insulating member 120 can be minimized.

Referring to FIGS. 2 and 3, it can be seen that the height of the spacing space 130 is formed by the vibration insulating member 140. Therefore, in order to maximize the sound insulation function, the thickness of the vibration insulation member 140 is set to a value within a range of 10 mm to 30 mm, and the insulation member 120 disposed on the outer circumference of the vibration insulation member 140 , The thickness of the E Glass fiber is set to a value within a range of 15 mm or more and 40 mm or less.

However, such a numerical range is a matter according to one embodiment of the present invention, and can be appropriately changed by those skilled in the art in consideration of the diameter of the piping body 110, the external environment, and the like.

3 and 4, the vibration insulating member 140 may be provided in a ring shape continuous in a circumferential direction of the pipe body 110, or may be formed in a ring shape that is discontinuous in the circumferential direction of the pipe body 110 As shown in FIG.

In addition, the vibration insulating member 140 may be a vibration damper such as a sponge material as well as a rubber material. A vibration damping material refers to a material having a capability of absorbing vibration energy.

However, such a form is not limited to the present invention, but can be appropriately modified and applied by those skilled in the art.

According to the ship pipe according to the preferred embodiment of the present invention configured as described above, the noise shielding ability can be improved as compared with the pipe having the same thickness, and the pipe can be easily installed even in a narrow space of the ship due to the reduced pipe thickness It is effective.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be apparent to those of ordinary skill in the art.
