As shown in fig. 1 to fig. 3, the present embodiment provides a pipeline assembly 100 for a compressor pipeline, the pipeline assembly 100 includes a first pipeline 110 and a sleeve 120, the first pipeline 110 includes a first pipe section 111 and a second pipe section 112 connected to each other, the sleeve 120 may be sleeved on the first pipe section 111, an inner wall of the sleeve 120 is connected to an outer wall of the first pipe section 111, and outer walls of the sleeve 120 corresponding to the first pipe section 111 may be sleeved to other pipelines, so as to achieve connection and fixation between the first pipeline 110 and other pipelines.

It is understood that the sleeve 120 may include a connection section 121 and a protection section 122, the connection section 121 is sleeved on the outer side of the first pipe section 111, and the protection section 122 is connected with the connection section 121 and extends to the outer side of the second pipe section 112, wherein a protection groove 101 may be formed between the inner wall of the protection section 122 and the outer wall of the second pipe section 112, that is, the inner wall of the protection section 122 and the outer wall of the second pipe section 112 are not in direct contact, but a gap is formed between the inner wall of the protection section 122 and the outer wall of the second pipe section 112.

When the first pipeline 110 needs to be welded with other pipelines, the sleeve 120 is used as an intermediate transition part, and when heat is received outside the sleeve 120, the protective groove 101 can block heat transfer, and the heat cannot be directly transferred to the second pipe section 112 through the sleeve 120 in a heat conduction manner.

In some embodiments, the groove width of the protection groove 101 may be greater than or equal to 0.1mm, including but not limited to 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or larger, and the size of the protection groove 101 may be regarded as the size of the gap between the inner wall of the protection section 122 of the casing 120 and the outer wall of the second pipe section 112, so the groove width of the protection groove 101 may be designed according to the size and material heat conduction performance of the first pipe 110 and the external heating condition, and the embodiment of the present application does not specifically limit the groove width of the protection groove 101.

It should be noted that, in the embodiment of the present application, the protective groove 101 formed between the sleeve 120 and the steel pipe is used to block welding flame when the first pipeline 110 is connected to another pipeline, so as to avoid forming a heat affected zone on the outer wall of the steel pipe, and thus when the first pipeline 110 is cooled after welding is completed, tensile stress generated at the connection position between the first pipe section 111 and the second pipe section 112 can be reduced, and the risk of cracks at the connection position between the first pipe section 111 and the second pipe section 112 after welding is effectively reduced.

The specific shape of the protection groove 101 will be described in detail below.

In a possible implementation manner, the protection groove 101 may be annular around the circumference of the second pipe segment 112, so that all positions of the circumference of the second pipe segment 112 are protected by the protection groove 101, thereby effectively avoiding the connection position of the second pipe segment 112 and the first pipe segment 111 from directly contacting with the welding flame, and reducing the risk of cracks at the position of the second pipe segment 112 close to the first pipe segment 111.

It can be understood that the first pipe section 111 and the second pipe section 112 may be coaxially disposed, and both the first pipe section 111 and the second pipe section 112 may be circular pipes, that is, both the first pipe section 111 and the second pipe section 112 are cylindrical, the connection section 121 of the casing 120 and the first pipe section 111 have matching shape structures, the protection section 122 of the casing 120 and the second pipe section 112 have matching shape structures, and the connection section 121 and the protection section 122 may also be coaxially disposed, so that the protection groove 101 may be an annular gap between the protection section 122 and the second pipe section 112.

Illustratively, the protection groove 101 may have an equal groove width along the circumferential direction of the second pipe segment 112, that is, the inner wall of the protection segment 122 and the outer wall of the second pipe segment 112 have an equal-sized gap in the circumferential direction of the second pipe segment 112, so that the protection groove 101 may have the same or similar thermal insulation effect at different positions of the second pipe segment 112 in the circumferential direction, and avoid heating differences at different positions of the second pipe segment 112 in the circumferential direction.

It should be noted that the shape of the protection groove 101 is mainly determined by the shapes of the second pipe segment 112 and the protection segment 122, and the shape of the protection segment 122 may match the shape of the second pipe segment 112, and the protection groove 101 may have different structures according to different cross-sectional shapes of the second pipe segment 112, including but not limited to a circular ring shape, an elliptical ring shape, a square ring shape, or other regular-shaped ring shapes, and the embodiment of the present invention is not limited thereto.

It will be understood by those skilled in the art that the above description of the shape of the protection groove 101 mainly refers to the sectional shape of the protection groove 101, the sectional shape of the protection groove 101 affects the protection range of the second pipe segment 112 in the circumferential direction, and furthermore, the extension length of the protection groove 101 along the axis of the second pipe segment 112 determines the protection range of the second pipe segment 112 in the length direction thereof by the protection groove 101.

Since the first pipe section 111 is a position where the first pipeline 110 is connected to other pipelines, as the second pipe section 112 extends away from the first pipeline 110, the farther the second pipe section 112 is from the first pipe section 111, the smaller the external heat influence on the second pipe section 112 is, and the protective section 122 only needs to cover the position of the second pipe section 112 connected to or close to the first pipe section 111, so as to prevent the second pipe section 112 from forming a heat-affected zone where cracks may occur.

In some embodiments, the length of the protection groove 101 along the axial direction of the second pipe segment 112 may be approximately the length of the protection segment 122 along the axial direction of the second pipe segment 112, and the length of the protection segment 122 along the axial direction of the second pipe segment 112 may be 3mm to 20mm, that is, the length of the protection groove 101 along the axial direction of the second pipe segment 112 may be 3mm to 20mm, so that a sufficient coverage length and area of the protection groove 101 for protecting the second pipe segment 112 can be ensured, and the risk of cracks can be further reduced.

Illustratively, specific dimensions of the protection groove 101 along the axial direction of the second pipe segment 112 include, but are not limited to, 3mm, 4mm, 5mm, 8mm, 10mm, 12mm, 15mm, 17mm, 19mm, 20mm, etc., and it is understood that setting a lower limit to the dimension of the protection groove 101 along the axial direction of the second pipe segment 112 can ensure that the protection section 122 can sufficiently protect the second pipe segment 112, and setting an upper limit to the dimension of the protection groove 101 along the axial direction of the second pipe segment 112, mainly considering that the second pipe segment 112 can have a need to be turned or be butted with other pipelines, so that the protection section 122 of the surface casing 120 can interfere with the second pipe segment 112 or other pipelines, and also can facilitate the installation and connection of the casing 120.

It should be noted that the groove width of the protection groove 101 along the axial direction of the second pipe segment 112 may be kept consistent, that is, the gap between the inner wall of the protection section 122 and the outer wall of the second pipe segment 112 along the axial direction may be kept constant, or the groove width of the protection groove 101 may also be gradually increased along the axial direction of the second pipe segment 112, that is, the protection section 122 may be in a horn shape relative to the second pipe segment 112, which is not specifically limited in this embodiment of the present application.

In a possible implementation manner, an end face of one end of the connection section 121, which is away from the protection section 122, may be flush with an end face of the first pipe section 111, and a length dimension of the connection section 121 of the sleeve 120 may be matched with a length dimension of the first pipe section 111, so that it may be ensured that the first pipe section 111 is all covered by the sleeve 120 in the axial direction, and further, when other pipelines are connected to the sleeve 120, reliability of connection between the other pipelines and the first pipeline 110 is ensured.

It is understood that the first pipeline 110 may be a steel pipe, for example, a stainless steel pipe, and the sleeve 120 may be a copper sleeve, which on one hand can reduce the material cost of the first pipeline 110, and on the other hand can ensure that the first pipeline 110 has sufficient structural strength and corrosion resistance, and when the sleeve 120 is sleeved with the first pipeline 110, the first pipe section 111 of the first pipeline 110 can support and reinforce the sleeve 120.

It should be noted that different portions of the first pipeline 110 may have different sizes, and the pipe diameters of the first pipe section 111 and the second pipe section 112 may be the same or different, and on one hand, the pipe sections may be set according to the flow demand of the medium that needs to circulate through the first pipeline 110, and on the other hand, the first pipe section 111 may be set according to the size of the pipeline that needs to be butted.
