Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of limiting pipe clamp, especially to a limiting pipe clamp and limiting insulation pipeline of insulation pipeline. BACKGROUND
[0002] In the shipbuilding industry, low-temperature pipeline systems (such as liquefied natural gas (LNG) transport ships) are usually used to transport low-temperature media such as liquefied natural gas (-163℃). When the low-temperature medium (such as LNG, -163℃) enters the pipeline system, it will cause the pipeline to rapidly cool, forming a temperature difference of about 180℃ with the ambient temperature, and the pipeline will produce a cold shrinkage displacement. We usually analyze the stress of these pipelines to determine the displacement of each pipe clamp position and the type of pipe clamp. In order to ensure the safety and stability of the system in an extremely low-temperature environment, various limiting pipe clamps are used to limit the axial or radial displacement (stress) of the pipeline to prevent excessive stress from causing pipeline failure or excessive stress from damaging some equipment nozzles.
[0003] In a low-temperature environment, the original pipe clamp (sleeve plus U-shaped bolt) can refer to Figure 5 , which has the following problems: 1) The original pipe clamp uses the pre-tightening force of the U-shaped bolt to clamp and fix the pipeline, achieving axial limitation of the pipeline. If the bolt is loose, this type of pipe clamp cannot limit the axial displacement of the pipe at that point; 2) The ship will be affected by waves, engine vibration, etc. during navigation, and the bolt columns on both sides of the U-shaped bolt of the original pipe clamp will be pushed and pulled by the pipeline, causing slight deformation and resulting in loose fixation and constraint failure; 3) The original pipe clamp must be fixed from the bottom of the insulation pipeline, and sometimes the space at the bottom of the insulation pipeline is too small to be fixed.
[0004] In summary, there is an urgent need for a limiting pipe clamp that can solve the above problems. INVENTION CONTENTS

[0041] Embodiment one
[0042] The utility model provides a kind of limiting pipe clamp of insulating pipeline, in combination with referring to Figure 1 And Figure 2 , including web plate 1, the inner wall of web plate 1 is used to be fixedly connected with the outer wall of insulating pipeline 7, web plate 1 is usually welded in the abdominal position of insulating pipeline 7, and is integrated with insulating pipeline 7, for the stress of the outer wall of insulating pipeline 7 is conducted to web plate 1, to disperse the stress of the outer wall of insulating pipeline 7, reduce the displacement risk of insulating pipeline 7 in the region.Combined with referring to Figure 1 And Figure 2The system also includes a gusset plate 2, a baffle plate 3, a first angle steel 4, and a second angle steel 5 connected in sequence. The gusset plate 2 and the baffle plate 3 are both connected to the outer wall of the web plate 1. The gusset plate 2 and the baffle plate 3 are typically welded and fixed to the outer wall of the web plate 1. One end of the second angle steel 5 is used to fix it to the hull structure or load-bearing wall, thereby limiting the movement of the insulating pipe 7. Specifically, it limits the large axial or radial displacement or stress generated by the insulating pipe 7 under low temperature or vibration conditions, reducing the risk of displacement of the insulating pipe 7 in that area. This invention is commonly used in ship hull piping; therefore, the second angle steel 5 is usually fixed to the hull structure. However, this does not preclude its application in piping systems in other fields. As a special note, in order to enhance the limiting ability of the limiting clamp on the insulating pipeline 7, the materials of the web plate 1, the elbow plate 2 and the baffle 3 are all independently selected from one type of austenitic stainless steel, such as any one of 316 stainless steel, 304 stainless steel, 316L stainless steel or 304L stainless steel, preferably 316L stainless steel. The materials of the first angle steel 4 and the second angle steel 5 are both steel, preferably Q235-B, so as to improve the deformation resistance of the web plate 1, the elbow plate 2, the baffle 3, the first angle steel 4 and the second angle steel 5, thereby further reducing the risk of displacement of the insulating pipeline 7 in this area.
[0043] Furthermore, in conjunction with reference Figure 1 and Figure 2 The shape of the inner wall of the web 1 matches the shape of the outer wall of the insulating conduit 7. The insulating conduit 7 is typically a hollow cylinder with a certain wall thickness. Therefore, the inner wall of the web 1 is arc-shaped, and its radius should be the same as the radius of the outer wall of the insulating conduit 7 to maximize the contact area between the inner wall of the web 1 and the insulating conduit 7, further reducing the risk of displacement of the insulating conduit 7 in this area. In the cross-section of the insulating conduit 7, the inner wall of the web 1 covers 1 / 3 to 1 / 2 of the circumference of the outer wall of the insulating conduit 7, that is, the arc of the web 1 is 120° to 180°. Compared with the limitation of the clamping position of traditional limiting clamps, the limiting clamp provided by this utility model can clamp at any position of the insulating conduit 7. Usually, 2 to 3 limiting clamps can be set on the insulating conduit 7, and the positions of these limiting clamps relative to the insulating conduit 7 are all different.

Figure 1 and Figure 2 The elbow plate 2 extends in the same direction as the radial direction of the insulating conduit 7, and the elbow plate 2 is perpendicular to the cross-section of the insulating conduit 7.

Figure 1 and Figure 2 The baffle 3 extends in the same direction as the radial direction of the insulating conduit 7, and the cross-section of the baffle 3 and the insulating conduit 7 are parallel. The baffle 3 and the elbow plate 2 are perpendicularly arranged. This T-shaped arrangement between the baffle 3 and the elbow plate 2 can further enhance the deformation resistance of the baffle 3 and the elbow plate 2, thereby further reducing the risk of displacement of the insulating conduit 7 in this area. Typically, the dimensions of the baffle 3 should meet the relevant dimensions in Embodiment 3 to ensure the deformation resistance of the baffle 3 itself.
[0047] The limiting clamp for the insulating conduit provided by this utility model, see reference. Figure 2 The first angle steel 4 includes a first adapter plate 41 and a first extension plate 42 connected sequentially and perpendicular to each other. The first adapter plate 41 is connected to the baffle 3. The extension direction of the first adapter plate 41 is the same as the radial direction of the insulating conduit 7, and the first adapter plate 41 is perpendicular to the cross-section of the insulating conduit 7. The extension direction of the first extension plate 42 is the same as the axial direction of the insulating conduit 7, and the first extension plate 42 is perpendicular to the cross-section of the insulating conduit 7. Generally, the dimensions of the first adapter plate 41 should meet the relevant dimensions in Embodiment 3 to ensure the deformation resistance of the first adapter plate 41, and the dimensions of the first extension plate 42 should meet the relevant dimensions in Embodiment 3 to ensure the deformation resistance of the first extension plate 42.
[0048] The limiting clamp for the insulating conduit provided by this utility model, in conjunction with reference to... Figure 3 and Figure 4 The second angle steel 5 includes a longitudinal support plate 51 and a transverse support plate 52 connected in sequence and perpendicular to each other. Both the longitudinal support plate 51 and the transverse support plate 52 are connected to the first extension plate 42. The extension direction of the longitudinal support plate 51 is the same as the radial direction of the insulating pipe 7, and the longitudinal support plate 51 is perpendicular to the cross-section of the insulating pipe 7. The extension direction of the transverse support plate 52 is the same as the axial direction of the insulating pipe 7, and the transverse support plate 52 is perpendicular to the cross-section of the insulating pipe 7.
[0049] The limiting clamp for the insulating conduit provided by this utility model, in conjunction with reference to... Figure 1 and Figure 2The first angle steel 4 and the baffle 3 are connected by fixing bolts. Further, the fixing bolts pass sequentially through the first angle steel 4, the insulating plate 6, and the baffle 3, fixing these three together. Optionally, refer to... Figure 1 The number of fixing bolts is 4, which improves the connection strength between the first angle steel 4, the insulating plate 6 and the baffle 3, thereby further strengthening the deformation resistance of the limit clamp.
[0050] This utility model also provides a method for using a limiting clamp for insulated pipelines, including the following steps:
[0051] 1) The inner wall of the web 1 is connected to the outer wall of the insulating pipe 7, usually by welding;
[0052] 2) One end of the second angle steel 5 is used to fix it to the hull structure or load-bearing wall, usually by welding.
[0053] As can be seen, when installing the limiting pipe clamp described in this utility model, the area of the insulating pipe 7 that is more prone to displacement can be selected for installation, and it can be installed from multiple directions of the insulating pipe 7. This is more flexible than the prior art, so as to reduce the risk of displacement in a specific area of the insulating pipe 7.

Figure 1 and Figure 2 The system also includes an insulating conduit 7, which comprises a conduit 71 and an insulating layer 72 surrounding the outer wall of the conduit 71. Each insulating conduit has a limiting clamp sequentially arranged along the axial direction of the conduit 71, and the relative positional relationship between the limiting clamp and the conduit 71 differs for each conduit. Compared to existing technologies, the limiting insulating conduit provided in this embodiment has limiting clamps installed in multiple directions on the conduit 71, not limited to installation below the conduit. This makes the limiting clamps more flexible during installation. Furthermore, compared to the repeated installation of multiple limiting clamps in the same position in existing technologies, installation in multiple directions can strengthen the limiting of areas of the conduit 71 prone to displacement, comprehensively reducing the risk of displacement of the conduit 71.
