The present invention relates to an improvement in the joint structure of a heat insulating cover that has a split structure, and more specifically relates to a joint structure of a heat insulating cover that allows the joint to be connected extremely easily and reliably without impairing heat insulation properties.

Conventionally, cylindrical insulation covers with a split structure, which has an extremely simple overall structure, have been used as insulation covers for pipes that transport ultra-low temperature liquefied gases such as LNG because it is necessary to easily install the covering after piping. It is used by joining together the joint parts, which are end faces, and further connecting the joint parts with the side end faces of other adjacent heat insulation covers. This type of heat insulating cover uses a synthetic resin foam such as hard polyurethane foam, which has excellent heat insulating properties, and a porous material such as glass wool or balsa wood, and exhibits a good heat insulating effect.

However, since ordinary adhesives are used alone to connect such joints, and in addition, there are many joints due to the structure, the heat insulation of the joints is poor, and improvements are desired. Furthermore, the larger the diameter of the tubular body, the more variation in the outer diameter of the tubular body and the inner diameter of the pre-formed heat insulating cover, which is a unique requirement for this type of cover that the tubular body must be covered after piping. Therefore, the dimensions cannot be ignored from the viewpoint of reliability and simplicity of construction.
Not only is it virtually impossible to join this type of cover to a tubular body, but even if the cover is covered with a certain gap, great care must be taken to maintain the dimensional accuracy of the heat insulating cover. In addition, there was a drawback in that consideration had to be given to the difference in expansion and contraction of the tube body and the heat insulating material depending on the operating temperature.

根本的な問題解決には至つていない。 On the other hand, the required thickness of the heat insulating cover, which has been designed and calculated for the purpose of improving the heat insulation of the joint part of the heat insulating cover, is divided into two or more layers as appropriate, and the position of the joint part of the first layer and the joint part of the second layer is Measures have been taken to lengthen the path for heat energy to dissipate from the joints by staggering the joints, but this method takes time to install and has the disadvantage of requiring insulation covers of various diameters to be prepared. It was hot. In addition, it is necessary to manage the dimensional accuracy of each heat insulating cover with different diameters, etc., and the fundamental problem has not been solved yet.

In order to achieve the above object, this invention provides a heat insulating cover with a split structure made of a heat insulating material that covers the outer peripheral surface of a tubular body made of a rigid material. Adopts a joint structure of the heat insulating cover in which a flexible porous material with a thickness greater than the gap is interposed, and the joint between the flexible porous material and the heat insulating cover is filled with adhesive and joined. This is what I did.

Therefore, even when covering a tubular body on which piping is laid with this type of heat insulation cover related to a split structure in which the joints on the split end faces and side end faces pose a particular problem, it is necessary to keep the dimensions of the pipes and the heat insulation cover. Even if there is an error, it can be adjusted using the intervening flexible porous material, so there is no need to pay extra attention to the accuracy of each dimension. Even though the heat insulating cover and the tubular body are integrated with adhesive,
It is possible to follow the expansion and contraction of the tubular body and heat insulating cover due to environmental temperature. There is no need to create a complicated structure in which the insulation cover is divided into two or more layers to lengthen the path for heat leakage, as in the past, and construction is extremely simple and can be completed in a short time. Excellent heat insulation effects can also be exhibited at the joints.
以下図面に従つて説明する。 This will be explained below with reference to the drawings.

着剤５が充填され接合されている。 In FIGS. 1 and 2, 1 is a piped tubular body, and 2 and 2' are heat insulating covers having a desired thickness and having a split structure that covers the outer peripheral surface of the tubular body 1. In FIG.
The insulation cover 2 at the joint part 3 of each insulation cover 2, 2',
As shown in the figure, a flexible porous material 4 thicker than the gap is interposed in the gap between the tubular body 2' and the tubular body 1, and the pores of the flexible porous material 4 and the heat insulating cover material are An adhesive 5 is filled in the gap between the joints 3 and the joints are joined.

おいても断熱性をもたせることができる。 Therefore, due to this joint structure, the variation in dimensions between the outer diameter of the tubular body 1 and the inner diameter of the heat insulating covers 2 and 2' is reduced.
It is possible to adjust using the flexible porous material 4,
In addition, by interposing the flexible porous material 4, the joint portion 3 can also be provided with heat insulation properties.

ある。 When the heat insulating covers 2 and 2' are used for heat insulation on the low-temperature side, and when a synthetic resin or rubber foam is used as the flexible porous material 4, a flexible porous material is used as in this embodiment. It is preferable to form a laminate in which the material 4 is laminated with the reinforcing material 6. As the reinforcing material used in this case, organic or inorganic fibrous materials with low elongation are suitable, and mesh-like fabrics of glass fibers are particularly suitable because of their low low-temperature elongation.

揮するからである。 The adhesive used for the joint 3 of the heat insulation cover may be a thermosetting resin adhesive such as polyurethane resin, epoxy resin, or unsaturated polyester, or rubber-based adhesive depending on the operating temperature and other environmental conditions. , a thermoplastic resin adhesive can also be used. It is also possible to use other adhesives such as asphalt or cement. However, the most preferable adhesive is a foaming polyurethane resin adhesive, which allows the adhesive to penetrate into the air bubbles and pores of the flexible porous material due to the foaming pressure, and also to penetrate into the slightest gaps, creating a rigid insulation cover. 2, 2' and tubular body 1
And in addition to adhering the insulation covers 2 and 2′,
This is because it foams and hardens, so it exhibits excellent performance in terms of heat insulation.

に対して追随可能とするからである。 Note that the adhesive may penetrate into the flexible porous material 4 only partially, but in this case, it is desirable to appropriately select the thickness of the flexible porous material 4. That is, the heat insulating cover 2,
The inner diameter of the tubular body 1 is designed to be larger in advance, and the thickness of the flexible porous material 4 is selected to be slightly thicker than 1/2 of this difference in diameter. The maximum value of the variation in the inner diameter of the heat insulating covers 2 and 2' is used as a reference value, and it is desirable to set the thickness to be about 5 to 50% thicker than 1/2 of this reference value. If the setting is within this range, the expansion/contraction rate due to temperature changes in the materials of the tubular body 1 and the heat insulating covers 2, 2' will normally be less than 2%, so even if there are changes in the environmental temperature or operating temperature, the expansion/contraction rate will be sufficient. This is because the flexible porous material can follow compression and expansion.

きる。 In this embodiment, hard polyurethane foam is used as the material for the heat insulating covers 2 and 2', and soft polyurethane foam is used as the flexible porous material 4.
Furthermore, the soft polyurethane foam is laminated with mesh-like glass fiber material on one side for reinforcement purposes, but this is made using ultra-low-temperature liquefied gas at -162°C.
This is an example of heat insulation construction for LNG transport pipes, and is intended to increase the safety of the heat insulation cover and the adhesive itself at such extremely low temperatures.
In the case of pipes for transporting LNG, steam, or hot water at a temperature of 60 to -100°C, there is no need to use reinforcing materials. However, in the case of a steam pipe, if necessary, a thin film layer such as a synthetic resin film or metal foil that does not allow steam to pass through may be provided on the inner surface of the heat insulating covers 2, 2'. Further, if necessary, a similar air permeable thin film may be provided on the surface layer of the heat insulating cover, or if the heat insulating cover 2, 2' is made of foam, it may be reinforced with a known reinforcing material such as fiber or inorganic material.

A flexible porous material 4 may be interposed over the entire area between the tubular body 1 and the heat insulating covers 2, 2'. Further, a flexible porous material may be interposed at the joints with the heat insulating covers 2, 2'.
