[0056] Insulated pipe structure

[0057] An insulating pipe structure according to one embodiment of the present invention is described with reference to FIGS. 1 and FIGS. 2. FIGS. 1 is a simplified illustration of an insulating pipe structure according to one embodiment of the present invention, and FIGS. 2 is a simplified illustration of a cross-section of an insulating pipe structure according to one embodiment of the present invention. Here, FIGS. 1 does not represent a manufacturing method, but is merely a separate representation along the length of the pipe to express each component, and the manufacturing process may be applied differently depending on the manufacturing environment and purpose.

[0058] Referring to FIGS. 1 and 2, the insulating pipe structure according to the present invention comprises: a first insulating member (310) and a second insulating member (320) that surround the outer surface of a pipe (1) and are spaced apart from each other in the longitudinal direction of the pipe (1); a ring-shaped support (100) that is positioned between the first insulating member (310) and the second insulating member (320) and supports the pipe (1); and a ring-shaped clamp (200) that fixes the support (100) on the outer surface of the support (100).

[0059] The first insulating member (310) and the second insulating member (320) may be provided by guiding the outer surface of the pipe, and for example, the first insulating member (310) and the second insulating member (320) may be provided by guiding and contacting the outer surface of the pipe.

[0060] The first insulating member (310) and the second insulating member (320) may be a laminate in which two or more sheet shapes are stacked. Although the laminate is shown as having four sheets stacked in FIG. 1 and five sheets stacked in FIG. 2, it may be a single sheet or a laminate in which two to ten sheets are stacked.

[0061] One or more of the first insulating member (310) and the second insulating member (320) may include a synthetic resin with a porous structure.

[0062] In a specific embodiment, one or more of the first insulating member (310) and the second insulating member (320) may include aerogel. The aerogel may be composed of nanoparticles with a size of 1 nm to 50 nm and has a porous structure, which has the advantage of excellent thermal insulation performance.

[0063] The above support (100) supports the load of the pipe (1) and compensates for the disadvantage that the insulation performance may be reduced due to external forces and deformation caused by the expansion and contraction of the pipe with only the insulation members (310, 320).

[0064] The above support (100) may have a thermal conductivity of 0.01 W / mK to 0.5 W / mK, specifically 0.1 W / mK to 0.4 W / mK, more specifically 0.2 W / mK to 0.3 W / mK.

[0065] The support (100) may have a compressive strength of 1 MPa to 500 MPa, specifically 100 MPa to 450 MPa, more specifically 200 MPa to 400 MPa. Within this range, deformation of the pipe can be minimized and the thermal insulation performance can be prevented from deteriorating.

[0066] The support (100) may include one or more of G-10 / FR-4, bakelite, epoxy glass laminate, CFRP, GRP, and micarta.

[0067] The clamp (200) above serves to maintain the support (100) so that it can fix the pipe, and by combining with the base (500) described later, it can prevent the pipe (1) from being deformed on the fixed object.

[0068] Referring to FIG. 2, the clamp (200) may have a wider width than the support (100). Specifically, the clamp (200) may be formed with a width corresponding to the sum of the widths of the support (100), the first insulating member (310), and the second insulating member (320). More specifically, the clamp (200) may be formed with a width corresponding to the sum of the widths of the support (100), the outermost first insulating member (310), and the second insulating member (320).

[0069] In a specific embodiment, either of the support (100) and the clamp (200) may be provided with a protrusion for connection, and the other of the support (100) and the clamp (200) may be provided with a groove corresponding to the protrusion for connection.

[0070] Referring to FIG. 3, in one embodiment, the support (100) may include: a body portion (110) forming a ring-shaped body that supports the pipe (1) between the first insulating member and the second insulating member; and a protrusion (130) that is coupled to a groove portion (250) of a clamp (200) with a width narrower than that of the body portion (110). At this time, the clamp (200) may be provided with a bed (210) and a pair of walls (230) for forming a groove portion (250) corresponding to the protrusion (130) of the support (100). Thus, the protrusion (130) of the support (100) can be inserted and coupled to the groove portion (250) of the clamp (200).

[0071] Referring to FIG. 4, the insulating pipe structure may further include a base (500) that is coupled with the clamp (200) to fix the insulating pipe structure to a fixing target.

[0072] Hereinafter, with reference to FIG. 5, an insulating pipe structure according to another embodiment of the present invention will be described. FIG. 5 is a simplified cross-section of an insulating pipe structure according to another embodiment of the present invention.

[0073] The above-described insulating pipe structure may further include an insert (400) that is provided between the pipe (1) and the support (100) and has a thermal conductivity lower than that of the support (100).

[0074] Although the support (100) supplements the rigidity that is insufficient with only the insulating members (310, 320) to prevent deformation and fix the pipe (1), the thermal conductivity of the support (100) is higher than that of the insulating members (310, 320), so a problem may arise where the thermal insulation performance is reduced.

[0075] Accordingly, by providing an insert (400) with a lower thermal conductivity than the support (100) between the pipe (1) and the support (100), the thermal insulation performance of the pipe can be further improved.

[0076] The above insert (400) may have a thermal conductivity of 0.01 W / mK to 0.1 W / mK, specifically 0.02 W / mK to 0.03 W / mK.

[0077] The above insert (400) may have a compressive strength of 50 MPa to 150 MPa, specifically 60 MPa to 120 MPa.

[0078] The above insert (400) has a density of 100 kg / m³ 3 up to 900 kg / m² 3 , specifically 200 kg / m² 3 up to 500 kg / m² 3 , more specifically 250 kg / m² 3 up to 400 km / m 3 , even more specifically 290 km / m 3 Up to 350 km / m 3 It could be.

[0079] Hereinafter, with reference to FIGS. 6 and FIGS. 7, an insulating pipe structure according to another embodiment of the present invention will be described. FIGS. 6 is a simplified cross-section of an insulating pipe structure according to another embodiment of the present invention, and FIGS. 7 is a simplified illustration of the coupling relationship between a clamp, a support, and an insert according to another embodiment of the present invention.

[0080] In another embodiment, the body of the support (100) may be formed with an inclined portion (150) that narrows in width toward the pipe direction and a tapered portion (170) that contacts the insert (400) with a narrow width. In this case, the support (100) can minimize the contact cross-section with the pipe (1), thereby improving thermal insulation performance.

[0081] Additionally, the insert (400) may have a notch (410) formed therein for joining in correspondence with the shape of the taper (170) of the support body. Through this structure, stress distribution can be made more efficient, fixing strength can be improved, and thermal insulation performance can be further improved.

[0082] Referring to FIG. 8, in another embodiment, the insulating pipe structure is provided with a spaced-apart pair of supports (100), and two pairs of walls (230) corresponding to each of the supports (100) are formed on the bed of the clamp (200), and a third insulating member (330) may be provided between the pair of supports (100).

[0083] Referring to FIG. 9, as another embodiment, the wall of the clamp (200) as a means of being coupled with the support may include a single wall (240) instead of a pair of walls (230). The support (100) may include a body portion (110) forming a ring-shaped body that supports the pipe (1) between the first insulating member (310) and the second insulating member (320); and a groove portion (160) formed in the body portion (110) and coupled with the single wall (240) of the clamp (200). Thus, the single wall (240) of the clamp (200) can be inserted into and fixed in the groove portion (160) of the support (100).

[0084] In this way, the support (100) and the clamp (200) can be combined and fixed through various types of combined structures.

[0085] Additionally, the above-described insulating pipe structure may further include a pair of inserts (400) provided between the pipe (1) and the pair of supports (100), having a thermal conductivity lower than that of the supports (100).

[0086] Here, the detailed structure of the support (100), clamp (200), and insert (400) may be the same as the detailed structure described in the other embodiment.

[0087] Referring to FIG. 10, the support (100) may include two semicircular members, wherein the semicircular members may include a fastening part (195) on one side that is separable and connectable to each other; and a hinge part (190) on the other side to which the separated semicircular members are hinge-connected.

[0088] Although the structure of the fastening part (195) and the hinge part (190) is illustrated in FIG. 10, in other embodiments, the support (100) may include two semicircular members, wherein the semicircular members may be provided with a fastening part (195) on one side and the other side that can be separated and combined with each other. That is, the combination of the semicircular members can be realized with two fastening parts (195).

[0089] Any specific structure of the hinge part (190) and the fastening part (195) can be applied as long as it is obvious to a person skilled in the art.

[0090] Referring to FIG. 11, the clamp (200) may include two semicircular members, wherein the semicircular members may include a fastening part (295) on one side that is separable and connectable to each other; and a hinge part (290) on the other side to which the separable semicircular member is hinge-connected.

[0091] Although the structure of the fastening part (295) and the hinge part (290) is illustrated in FIG. 11, in other embodiments, the clamp (200) may include two semicircular members, wherein the semicircular members may be provided with a fastening part (290) on one side and the other side that can be separated and joined to each other. That is, the joining of the semicircular members can be realized with two fastening parts (295).

[0092] Any specific structure of the hinge part (290) and the fastening part (295) can be applied as long as it is obvious to a person skilled in the art.

[0094] The present invention has the effect of improving fixing and supporting forces through the detailed structure of the support and clamp.
