Description

Technical Field

[0001] The utility model relates to the field of gas field equipment, in particular to a pipe sleeve device. Background Art

[0002] With the development of gas fields today, corrosion of hydrogen sulfide natural gas transmission pipelines has occurred and has a tendency to gradually intensify, causing frequent corrosion thinning points in hydrogen sulfide natural gas transmission pipelines. The transportation process of hydrogen sulfide natural gas is as follows: hydrogen sulfide natural gas, water and impurities seep from the formation to the bottom of the well under pressure-driven operation, and then flow through the wellbore pipe through the gas production wellhead, and after insulation, pressure reduction and separation of water and impurities, enter the natural gas transmission pipeline installed with an insulation layer, and are gathered at the Yuanba Gas Field Gas Gathering Station and uniformly transported to the natural gas purification plant for desulfurization and external transmission. During the operation of the gathering and transmission pipelines, in order to reduce the corrosion of hydrogen sulfide to the pipelines, batch treatment of pipeline cleaning and coating is carried out regularly. However, due to the characteristics of hydrogen sulfide and the effect of water, corrosion of natural gas gathering and transmission pipelines is still inevitable, especially in the middle and late stages of gas field development.

[0003] The corrosion control process of gathering and transportation pipelines is generally divided into two steps. The first step is to regularly carry out intelligent detection of the wall thickness of the gathering and transportation pipelines, and find out the location of the corrosion thinning points by sorting and analyzing the detection data. The second step is to carry out excavation and stripping of the insulation layer for verification and detection of the thinning points. After evaluation, the pipe section is replaced or reinforced, and finally the insulation layer is restored.

[0004] Whether it is replacing a pipe section or reinforcing a pipeline, the construction work requires the restoration of the insulation layer. Since the surface of the insulation layer is a protective shell made of plastic material, due to its own weight and other factors, it is very easy to cause the thickness of the insulation layer around the pipeline to be uneven (eccentric), or even direct contact between the pipeline and the protective shell, resulting in poor pipeline insulation effect. Utility Model Content

[0005] The utility model aims to overcome the problem in the prior art that the thickness of the thermal insulation layer restored after replacing or reinforcing the pipeline is prone to unevenness, and provides a pipe sleeve device.

[0006] In the first aspect, the utility model provides a pipe sleeve device, which includes a pipe body, a shell is provided on the outside of the pipe body, a gap is provided between the shell and the pipe body, a grouting port is provided on the shell, and a plurality of support module groups with the same structure are provided in the gap.

[0007] The utility model discloses a pipe sleeve device, wherein a pipe body for conveying liquid is arranged inside the pipe sleeve device, and an outer shell is arranged outside the pipe body, and the outer shell can protect the inner pipe body, and a gap portion is arranged between the outer shell and the pipe body, and by arranging the gap portion between the pipe body and the outer shell, it is ensured that a heat-insulating layer can be generated between the pipe body and the outer shell, and a plurality of support module groups with the same structure are arranged in the gap portion, and the outer shell and the pipe body are supported by the plurality of support module groups with the same structure, so that the pipe body and the outer shell can be coaxial, so that the straight-line distances from various positions of the pipe body to the outer shell are the same, and it is ensured that when the heat-insulating layer is subsequently made in the gap portion, the thickness of the heat-insulating layer can be uniform, thereby improving the heat-insulating effect.

[0008] Preferably, the shell body is an open sleeve structure, and the shell is a PVC tube.

[0009] By setting the outer shell as an open sleeve structure, the outer shell can be sleeved with the support module group and the abutment between the support module group and the inner wall of the outer shell is ensured. Since the PVC pipe has a certain toughness, the outer shell can be completely sleeved on the support module group.

[0010] Preferably, each of the support module groups is arranged at the head end and / or the tail end of the pipe body.

[0011] The coaxial position relationship between the pipe body and the outer shell can be always ensured, thereby ensuring the uniform thickness of the insulation layer produced subsequently.

[0012] Preferably, a plurality of binding devices are provided outside the shell, and the setting positions of the binding devices correspond to the setting positions of the supporting module groups.

[0013] By tying the binding device at the corresponding position of the support module group, the tightness of the connection between the support module group and the shell can be ensured, and sliding between the support module group and the shell can be avoided.

[0014] Preferably, each of the support module groups comprises a plurality of support modules, and the support modules are arranged circumferentially along the pipe body.

[0015] The relative positions of the outer shell and the pipe body can be fixed by the circumferentially arranged supporting modules to avoid sliding or falling off during the later production of the thermal insulation layer.

[0016] Preferably, adjacent support modules are arranged at intervals, and one end of the support module is connected to the outer wall of the pipeline body, and the other end is connected to the inner wall of the shell.

[0017] By connecting one end of the support module to the outer wall of the pipeline body and the other end to the inner wall of the shell, a solid support structure is formed, which improves the stability and durability of the entire device. In addition, multiple support modules can avoid stress concentration problems and increase the service life of the pipeline device.

[0018] Preferably, an adhesive portion is provided on the outer wall of the pipe body, one end of the adhesive portion is connected to the outer wall of the pipe body, and the other end of the adhesive portion is connected to the support module.

[0019] The bonding part can greatly enhance the connection strength between the outer wall of the pipeline body and the support module, ensuring the stability and reliability of the structure. The bonding part can also absorb the vibration and impact generated by the pipeline during operation, reducing damage to the structure.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

The utility model discloses a pipe sleeve device, wherein a pipe body for conveying liquid is arranged inside the pipe sleeve device, and an outer shell is arranged outside the pipe body, and the outer shell can protect the inner pipe body, and a gap portion is arranged between the outer shell and the pipe body, and by arranging the gap portion between the pipe body and the outer shell, it is ensured that a thermal insulation layer can be arranged between the pipe body and the outer shell, and a plurality of support module groups with the same structure are arranged in the gap portion, and the outer shell and the pipe body are supported by the plurality of support module groups with the same structure, so that the pipe body and the outer shell can be coaxial, so that the straight-line distance from each position of the pipe body to the outer shell is the same, so that when the thermal insulation layer is subsequently made in the gap portion, the thickness of the thermal insulation layer can be uniform, thereby improving the thermal insulation effect.

When the thermal insulation layer needs to be made, the pipeline device injects slurry from the grouting port 21 into the gap portion 3 to form the thermal insulation layer. Since the support module group 4 fixes the relative position between the outer shell 2 and the pipeline body 1, the relative position of the outer shell 2 and the pipeline body 1 remains unchanged when the thermal insulation layer is subsequently made, thereby ensuring that the thickness of the thermal insulation layer after forming is uniform and improving the thermal insulation effect of the pipeline device. The support module group 4 is arranged at the head end and / or the tail end of the pipe sleeve device.

[0035] In one or several embodiments, the shell 2 is made of PVC material and is an open sleeve. By setting the shell 2 as an open sleeve, it can not only ensure that the shell 2 can be socketed with the support module group 4, but also ensure that the inner wall of the shell 2 can abut against the support module group 4.

[0036] In one or more embodiments, each support module group 4 is composed of a plurality of support module groups 4, and a plurality of support modules 41 in each support module group 4 are arranged circumferentially along the pipe body 1, and the relative position of the pipe body 1 and the housing 2 can be better fixed by the plurality of support modules 41;

[0037] Furthermore, two adjacent support modules 41 in each support module group 4 are arranged at intervals, and the intervals between the support modules 41 and the support modules 41 enable the slurry to be transferred to the entire pipeline device through the intervals during subsequent grouting, such as Figure 2 and Figure 3 shown.

[0038] In one or more embodiments, the outer periphery of the pipe body 1 is provided with an adhesive portion 11, so that the pipe body 1 can be connected to each support module 41 through the adhesive portion 11;

[0039] Furthermore, one end of the adhesive portion 11 is connected to the pipe body 1, and the other end is connected to the inner wall of the shell 2, so that the relative position of the pipe body 1 and the shell 2 will not be offset. Figure 1 and Figure 2 shown.

[0040] In one or more embodiments, each of the support module groups 4 is arranged at intervals along the extension direction of the pipe body 1. Figure 2 shown.

[0041] Example 2

[0042] This embodiment 2 is a method for using and installing a pipe sleeve device in embodiment 1. When the original gas field pipeline needs to be replaced or replaced, the original pipeline shell is knocked off, and an adhesive portion 11 is set on the periphery of the pipeline body, and one end of a support module group 4 composed of a plurality of support modules 41 is pasted on the adhesive portion 11, and then the inner wall of the shell 2 is sleeved with the support module group 4 through the opening of the shell 2, and a binding device 5 is set on the outer wall of the shell 2, and then the gap between the shell 2 and the pipeline body 1 is grouting through the grouting port 21 to form a new insulation layer;
