Description

Technical Field

[0001] The utility model belongs to the technical field of composite pipe welding, and in particular relates to a bimetallic composite pipe support welding anti-deformation device. Background Art

[0002] Bimetallic composite pipe is a new type of pipe made from a composite of two metals. Its base layer is ordinary carbon steel, which offers high strength and can withstand the operating pressures of the piping system. The cladding layer is a corrosion-resistant alloy material, typically at least 3mm thick, offering excellent corrosion resistance. Bimetallic composite pipe overcomes the singularity and limitations of traditional metal materials. The carbon steel base ensures the overall strength and mechanical performance of the pipe, while the corrosion-resistant alloy cladding offers excellent corrosion resistance, significantly extending the pipe's service life and reducing operating costs. As a result, it is widely used in the offshore oil and gas industry.

[0003] When bimetallic composite pipe is used as the main pipeline, since branch pipes need to be led out through pipe seats, it is necessary to drill holes in the composite pipe and weld the pipe seats to the hole positions.

[0004] However, during the welding process, the cylindrical pipe structure is disrupted by the holes, making it very susceptible to deformation. Specifically, the holes disrupt the stability of the cylindrical pipe, and the stress generated by welding causes the pipe to deform. This deformation can lead to poor sealing during subsequent use. Utility Model Content

[0005] Based on the above background, the purpose of the present invention is to provide a bimetallic composite pipe support welding anti-deformation device.

[0006] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0013] During the process of pushing and tightening the push seat, the curved head slides in the slope groove. Under the push of the slope groove, the arc-shaped guard plate is continuously tightened and pressed against the inner wall of the composite pipe.

[0014] Preferably, a spring is sleeved on the slide rod, and two ends of the spring are respectively fixedly connected to the arc-shaped guard plate and the side wall of the push ring seat.

[0039] Example 1

[0040] like Figure 1-5 The device, shown in Figure 1, includes a bimetallic composite pipe support welding anti-deformation device that supports the composite pipe during welding. The anti-deformation mechanism supports the inner wall of the pipe on both sides of the welding position during pipe welding, thereby preventing pipe deformation during welding.

[0041] Specifically, the support and deformation prevention mechanism includes two support components symmetrically arranged on the front and rear sides (the two support components support both sides of the welding position on the pipeline). The specific structure of the support component is:

[0042] The supporting assembly comprises a pushing ring seat 1 , the outer side wall of which is assembled and connected with a plurality of arc-shaped guard plates 2 ; the arc-shaped guard plates 2 are slidably mounted on the pushing ring seat 1 through a spring telescopic structure.

[0043] Specifically, the spring expansion and contraction structure includes a slide rod 61 fixedly connected to the inner sidewall of the curved guard plate 2. The inner end of the slide rod 61 extends through the push ring seat 1. A spring 62 is sleeved on the slide rod 61, with both ends of the spring 62 fixedly connected to the sidewalls of the curved guard plate 2 and the push ring seat 1. During operation, the push ring seat 1 and the curved guard plate 2 are pushed into the pipe by squeezing the curved guard plate 2 inward, inserting it into the pipe, and then pushing it to the supporting position for support.

[0044] At the same time, a curved head 611 is integrally formed at the inner end of the slide rod 61 .

[0045] Correspondingly, the above-mentioned support assembly also includes a tensioning component for tensioning the arc-shaped guard plate 2, and the tensioning component includes a tightening push seat 4, and the tightening push seat 4 is provided with a plurality of slope grooves corresponding to the curved head 611 (that is, the slot position at one end is low, and the slot position at the other end is high), and the curved head 611 is limitedly slid in the slope groove (the shape of the slope groove is arc-shaped); in the process of pushing the tightening push seat 4, the curved head 611 slides in the slope groove (uphill process), and under the push of the slope groove, the arc-shaped guard plate 2 is continuously tightened and pressed against the inner wall of the composite pipe.

[0046] Specifically, as the curved head 611 slides uphill in the slope groove, the slope groove supports the sliding rod 61 and the arc-shaped guard plate 2 toward the outside, so that the arc-shaped guard plate 2 is fully pressed against the inner wall of the pipe.

[0047] The above-mentioned pressing push seat 4 is threadedly connected to a length adjustment rod 5, and the length adjustment rod 5 includes a first rod portion threadedly connected to the pressing push seat 4, and the first rod portion is threadedly connected to the adjustment rod portion (a threaded cavity adapted to the adjustment rod portion is provided on the first rod portion, and the threaded structure on the adjustment rod portion is threaded in the threaded cavity), and the outer end of the adjustment rod portion is fixedly connected to a handle rod.

[0048] By turning the handle bar, the curved head 611 is limited and slides in the slope groove, and the arc-shaped guard plate 2 can be rotated to adjust the support position.

[0049] At the same time, several drawstrings are fixedly assembled and connected to the push ring base 1. Specifically, two drawstrings 3 are hung on the rear side wall of the rear push ring base 1, and two drawstrings 3 are hung on the front side wall of the front push ring base 1 (specifically, a draw ring base 311 is fixedly connected to the push ring base 1, and a draw ring 311 is rotatably connected to the draw ring base 311).

[0050] During the working process, the pull rope 3 is pre-inserted into the pipe (can be matched with a wire, for example) and passed through the other side of the pipe. At this time, the operator pulls the support assembly to the vicinity of the support position, and then pushes the push seat 4-length adjustment rod 5 deep into the pipe until the slope groove contacts the curved head 611 and is tensioned as described above.

[0051] After welding is completed, the entire device is pulled out again using the pull rope 3 (while using the push seat 4 and the length adjustment rod 5 to push the support assembly out, the push seat 4 is firmly pressed and it is not easy to push out the support assembly). With the pull rope 3 method, the curved guard plate 2 is only pulled tightly by the spring 62, making it easy to pull out.

[0052] Example 2

[0053] like Figure 1-5As shown, the aforementioned support assemblies are connected via a plug-in structure. During operation, the support assemblies are inserted from both sides of the pipe and plugged together, ensuring that the two support assemblies are located on both sides of the welding position. Subsequently, the slope groove is pressed against the curved head 611 in the above-mentioned manner, thereby tightening the curved guard plate 2.

[0054] Specifically, the plug-in structure includes a plug-in rod 43 fixedly connected to the push seat 4 on one side; a plug-in slot 42 is provided on the push seat 4 on the other side to cooperate with the plug-in rod 43. A plurality of elastic protrusions 431 are installed on the plug-in rod 43 (the outer end of the elastic protrusion 431 is a curved end).

[0055] The wall of the plug slot 42 is provided with an elastic buckle slot 421 that cooperates with the elastic protrusion 431. The plug rod 43 is provided with a slot body that is slidably connected to the elastic protrusion 431. The slot body is fixedly connected to the inner spring 62, and the inner spring 4311 is fixedly connected to the elastic protrusion 431.

[0056] After the support components on both sides are pulled in by the above-mentioned pull rope 3, the length adjustment rods 5 on both sides are used to push the push seat 4 tightly until the plug rod 43 is inserted into the plug slot 42 on the other side (at this time, the support components are further approached to each other until they are in contact with each other and support at the corresponding position), and the elastic protrusion 431 is elastically squeezed into the slot body to complete the locking. The operator can then rotate and twist the length adjustment rod 5 on one side to achieve synchronous rotation of the support components on both sides and adjust the support position of the support plate, further increasing the support convenience. Ensure that the pipes at the welding position are fully supported on all sides without blind spots.

[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
