[0022] Reference Figure 1The embodiment of the present application discloses a pipe assembly, the disclosed pipe assembly comprises a first pipe body 10, a second pipe body 20, a clamp assembly 30, a mounting assembly 40 and a fastening assembly 50.

[0023] The first pipe body 10 and the second pipe body 20 are both used for conveying fluid, for example, the first pipe body 10 and the second pipe body 20 can both be fracturing pipes used for conveying fracturing fluid. Exemplarily, the first pipe body 10 and the second pipe body 20 can both be flange pipes, that is, the end portions of the first pipe body 10 and the second pipe body 20 can be provided with flanges to be connected with other pipe bodies through the flanges. Alternatively, the first pipe body 10 and the second pipe body 20 can also be flexible pipes.

[0024] To realize the connection of the first pipe body 10 and the second pipe body 20, the first pipe body 10 is provided with a first connecting end 11, the second pipe body 20 is provided with a second connecting end 21, and the clamp assembly 30 is connected with the first connecting end 11 and the second connecting end 21 respectively, so that the first connecting end 11 and the second connecting end 21 can be fastened together through the clamp assembly 30, thereby realizing the connection of the first pipe body 10 and the second pipe body 20 and ensuring the firmness and stability of the connection.

[0025] The mounting assembly 40 is arranged on at least one of the first connecting end 11 and the second connecting end 21. Alternatively, the mounting assembly 40 can be a group, in which case the mounting assembly 40 can be arranged on the first connecting end 11, or the mounting assembly 40 can be arranged on the second connecting end 21; of course, the mounting assembly 40 can also be two groups, in which case the two groups of mounting assemblies 40 are arranged on the first connecting end 11 and the second connecting end 21 respectively; of course, the mounting assembly 40 can also be other numbers, which can be set according to actual working conditions.

[0026] To realize the fastening of the clamp assembly 30, in the embodiment of the present application, the fastening assembly 50 is connected with the clamp assembly 30 and fastens the clamp assembly 30 to the first connecting end 11 and the second connecting end 21, so as to ensure the reliability of the connection of the clamp assembly 30 with the first connecting end 11 and the second connecting end 21 and prevent the clamp assembly 30 from separating from the first connecting end 11 and the second connecting end 21 to cause leakage or separation of the connection of the first pipe body 10 and the second pipe body 20.

[0027] To realize the fastening of the mounting assembly 40, in the embodiment of the present application, the fastening assembly 50 is connected with the mounting assembly 40 and fastens the mounting assembly 40 to at least one of the first connecting end 11 and the second connecting end 21, so as to ensure the reliability of the connection of the mounting assembly 40 with at least one of the first connecting end 11 and the second connecting end 21 and prevent the mounting assembly 40 from separating from at least one of the first connecting end 11 and the second connecting end 21.

[0028] Based on the above setting, the clamping assembly 30 is fastened by the fastening assembly 50, so that the clamping assembly 30 can connect the first connecting end 11 of the first pipe body 10 and the second connecting end 21 of the second pipe body 20, and the mounting assembly 40 is fastened by the fastening assembly 50, so that the mounting assembly 40 is fastened to at least one of the first connecting end 11 and the second connecting end 21.

[0029] When the clamping assembly 30 is installed, the clamping assembly 30 can be supported by the mounting assembly 40 and the fastening assembly 50, which facilitates installation, and the clamping assembly 30 and the mounting assembly 40 share the fastening assembly 50, which can fasten the clamping assembly 30 and the mounting assembly 40, and can reduce the use of parts, which is conducive to reducing the weight and achieving lightweight design.

[0030] In some embodiments, the mounting assembly 40 can include a bearing portion 41 and a first fixing portion 42. The bearing portion 41 is circumferentially arranged on the first connecting end 11 or the second connecting end 21 along the pipe junction.

[0031] Optionally, the bearing portion 41 can have an arc-shaped structure to adapt to the shape of the outer wall of the first pipe body 10 or the second pipe body 20. In addition, the bearing portion 41 can also produce elastic deformation, so that the bearing portion 41 can be tightly held on the first connecting end 11 or the second connecting end 21, or separated from the first connecting end 11 or the second connecting end 21.

[0032] Exemplarily, the bearing portion 41 can be an arc-shaped plate, an arc-shaped strip or the like structure, and of course, other shapes are also possible, which are not limited here. The bearing portion 41 can be made of steel material, so that the bearing portion 41 can produce elastic deformation.

[0033] The first fixing portion 42 is respectively arranged at both ends of the bearing portion 41, that is, the first fixing portion 42 is arranged at both ends of the bearing portion 41, so that the first fixing portion 42 at both ends can be connected by the fastening assembly 50, so that the bearing portion 41 can be deformed to tightly hold on the outer wall of the first connecting end 11 or the second connecting end 21, to achieve fastening of the mounting assembly 40. Optionally, the first fixing portion 42 can be a plate-shaped structure, a block-shaped structure, a sheet-shaped structure or the like.

[0034] In consideration of the mounting assembly 40 being mounted on at least one of the first connecting end 11 and the second connecting end 21, and the clamp assembly 30 being mounted on the first connecting end 11 and the second connecting end 21, to avoid interference, the clamp assembly 30 can be located on one side of the bearing portion 41 along the axial direction of the pipe manifold. In this way, the clamp assembly 30 can be limited in the axial direction by the bearing portion 41 to prevent the clamp assembly 30 from moving freely, and the clamp assembly 30 can be positioned to ensure the installation accuracy of the clamp assembly 30, facilitating the installation of the clamp assembly 30.

[0035] Further, the first fixing portion 42 protrudes from the bearing portion 41 along the axial direction of the pipe manifold, and the two ends of the clamp assembly 30 are connected to the corresponding first fixing portion 42 through the fastening assembly 50. In this way, the clamp assembly 30 and the mounting assembly 40 can be fastened by the same fastening assembly 50, and installation interference between the clamp assembly 30 and the mounting assembly 40 can be effectively prevented.

[0036] Optionally, the first fixing portion 42 and the bearing portion 41 can be fixedly connected, such as welding, riveting, etc. Of course, the first fixing portion 42 and the bearing portion 41 can also be detachably connected, such as screwing, clamping, etc. In addition, the first fixing portion 42 and the bearing portion 41 can also be an integral structure, i.e., the entire mounting assembly 40 is manufactured by integral molding technology to improve manufacturing efficiency.

[0037] In some embodiments, the bearing portion 41 can include a plurality of bearing units arranged along the circumferential direction of the pipe manifold. The two ends of each bearing unit are respectively provided with a first fixing portion 42, and the first fixing portions 42 of adjacent two bearing units are butted. Based on this arrangement, the first fixing portions 42 of adjacent two bearing units can be fastened and connected by the fastening assembly 50, so that the sequential connection of the plurality of bearing units can be achieved, so that the bearing portion 41 can be wrapped on the outside of the first connecting end 11 or the second connecting end 21.

[0038] Optionally, each bearing unit can be an arc-shaped plate, an arc-shaped strip, or the like.

[0039] Illustratively, the bearing portion 41 can include two arc-shaped plates as the bearing units, and each arc-shaped plate is provided with a fixing plate as the first fixing portion 42 at its two ends. Of course, the bearing portion 41 can also include other numbers of bearing units, such as 3, 4, 5, etc.

[0040] In other embodiments, the bearing portion 41 can be an integral bearing unit, and the two ends of the integral bearing unit are respectively provided with a first fixing portion 42. The first fixing portions 42 at the two ends can be fastened and connected by the fastening assembly 50, so that the entire bearing unit can be wrapped on the outside of the first connecting end 11 or the second connecting end 21.

[0041] It should be noted that the specific form of the bearing part 41 can be selected according to the size of the first pipe body 10 or the second pipe body 20. For example, when the diameter of the first pipe body 10 or the second pipe body 20 is relatively large, the bearing part 41 can include a plurality of bearing units to be spliced on the outside of the first pipe body 10 or the second pipe body 20, so as to ensure that the bearing part 41 can be wrapped on the outside of the first pipe body 10 or the second pipe body 20. Of course, when the diameter of the first pipe body 10 or the second pipe body 20 is relatively small, the bearing part 41 can also ensure an entire bearing unit. In this case, it can also be ensured that the first pipe body 10 or the second pipe body 20 can enter the inside of the bearing part 41 from the opening of the entire bearing unit, so as to ensure that the bearing part 41 can be wrapped on the outside of the first pipe body 10 or the second pipe body 20.

[0042] In some embodiments, the first pipe body 10 can be provided with a circumferentially extending protrusion 12 formed along the pipe manifold at the outer wall close to the first connecting end 11. Correspondingly, the bearing part 41 and / or the first fixing part 42 can be provided with a circumferentially extending groove 43 formed along the pipe manifold, and the protrusion 12 is connected with the groove 43. Based on this arrangement, through the cooperation of the protrusion 12 and the groove 43, the limiting effect of the mounting assembly 40 in the axial direction of the pipe manifold can be achieved, so as to prevent the mounting assembly 40 from moving randomly in the axial direction of the pipe manifold, and the installation stability of the mounting assembly 40 is ensured.

[0043] Similarly, the second pipe body 20 can be provided with a circumferentially extending protrusion 12 formed along the pipe manifold at the outer wall close to the second connecting end 21. Correspondingly, the bearing part 41 and / or the first fixing part 42 can be provided with a circumferentially extending groove 43 formed along the pipe manifold, and the protrusion 12 is connected with the groove 43. Based on this arrangement, through the cooperation of the protrusion 12 and the groove 43, the limiting effect of the mounting assembly 40 in the axial direction of the pipe manifold can be achieved, so as to prevent the mounting assembly 40 from moving randomly in the axial direction of the pipe manifold, and the installation stability of the mounting assembly 40 is ensured.

[0044] Alternatively, the protrusion 12 can be an annular protrusion or a sector-shaped protrusion; correspondingly, the groove 43 can be an annular groove or a sector-shaped groove, which can be set according to the actual working conditions. In addition, the protrusion 12 can be one or more, and when the protrusion 12 is multiple, the multiple protrusions 12 are arranged along the circumferential direction of the pipe manifold; correspondingly, the groove 43 can be one or more, and when the groove 43 is multiple, the multiple grooves 43 are arranged along the circumferential direction of the pipe manifold.

[0045] Of course, in other embodiments, the protrusion 12 can also be provided on the bearing part 41 and / or the first fixing part 42, and the groove 43 is provided on the outer wall of the first pipe body 10. In this way, the limiting effect of the mounting assembly 40 in the axial direction of the pipe manifold can also be achieved.

[0046] In some embodiments, the clamp assembly 30 can include a clamping portion 31 and a second fixing portion 32, wherein the clamping portion 31 is arranged corresponding to the bearing portion 41. Specifically, the clamping portion 31 is arranged opposite to the bearing portion 41 along the axial direction of the manifold assembly, so as to be axially positioned and limited by the bearing portion 41.

[0047] Optionally, the clamping portion 31 can be provided with an arc-shaped structure to adapt to the shape of the outer wall of the first pipe body 10 and the second pipe body 20. In addition, the clamping portion 31 can also produce elastic deformation, so that the clamping portion 31 can be tightly clamped on the first connecting end 11 and the second connecting end 21, or separated from the first connecting end 11 and the second connecting end 21.

[0048] Exemplarily, the clamping portion 31 can be an arc-shaped plate, an arc-shaped strip or the like structure, and of course, can also be other shapes, which are not limited here. The clamping portion 31 can be made of steel material, so that the clamping portion 31 can produce elastic deformation.

[0049] The inner side of the clamping portion 31 is provided with a clamping groove 311 extending along the circumference of the manifold assembly; correspondingly, the first connecting end 11 can be provided with a first ring protrusion 111 extending along the circumference of the manifold assembly, and the second connecting end 21 can be provided with a second ring protrusion 211 extending along the circumference of the manifold assembly, the end face of the first ring protrusion 111 and the end face of the second ring protrusion 211 are in abutment, and the first ring protrusion 111 and the second ring protrusion 211 are both arranged in the clamping groove 311. Based on this arrangement, the first ring protrusion 111 and the second ring protrusion 211 can be accommodated in the clamping groove 311, and the first ring protrusion 111 and the second ring protrusion 211 are axially limited by the two side walls of the clamping groove 311 in the axial direction, so as to prevent the first ring protrusion 111 from separating from the second ring protrusion 211, and ensure the reliability and stability of the connection between the first pipe body 10 and the second pipe body 20.

[0050] The second fixing portion 32 is arranged at both ends of the clamping portion 31, i.e., the second fixing portion 32 is arranged at both ends of the clamping portion 31, so that the second fixing portion 32 at both ends can be connected by the fastening assembly 50, thereby making the clamping portion 31 deformed to tightly clamp on the outer wall of the first connecting end 11 and the outer wall of the second connecting end 21, so as to realize the fastening of the clamp assembly 30. Optionally, the second fixing portion 32 can be a plate-shaped structure, a block-shaped structure, a sheet-shaped structure or the like.

[0051] The second fixing portion 32 and the corresponding first fixing portion 42 are connected by the fastening assembly 50, so that the first fixing portion 42 and the second fixing portion 32 can be fastened together by the shared fastening assembly 50, so as to respectively realize the fastening of the clamp assembly 30 and the mounting assembly 40.

[0052] In some embodiments, two sides of the hoop groove 311 can be respectively provided with an edge portion 33 extending along the circumferential direction of the pipe assembly. Based on this, the edge portions 33 on the two sides can be used to limit the first connecting end 11 and the second connecting end 21 respectively, so as to prevent the first connecting end 11 from separating from the second connecting end 21.

[0053] Further, the inner side surface of the edge portion 33 can be provided with a groove portion 331 extending along the axial direction of the pipe assembly. In this way, the load borne by the hoop portion 31 can be dispersed through the groove portion 331, which is beneficial to optimizing the stress condition of the edge portion 33.

[0054] Optionally, the inner side surface of each edge portion 33 can be provided with a plurality of groove portions 331 arranged along the circumferential direction of the hoop portion 31, so as to optimize the stress condition in multiple areas.

[0055] In some more specific embodiments, the pipe assembly can include two mounting assemblies 40 respectively arranged at the first connecting end 11 and the second connecting end 21. Specifically, the two mounting assemblies 40 are arranged at the two sides of the clamp assembly 30, so as to axially position and axially limit the clamp assembly 30 from the two sides.

[0056] Among them, the first fixing portion 42 can be provided with a first fastening hole 421, and the second fixing portion 32 can be provided with two second fastening holes 321.

[0057] The first fastening hole 421 provided on the first fixing portion 42 of each mounting assembly 40 is arranged opposite to the two second fastening holes 321 provided on the same second fixing portion 32, and a fastening assembly 50 is arranged in the opposite first fastening hole 421 and second fastening hole 321. In this way, the fastening assembly 50 can be used to fasten the first fixing portion 42 and the second fixing portion 32, so as to fasten the clamp assembly 30 and the mounting assembly 40 respectively.

[0058] It should be noted that the bearing portion 41 of each mounting assembly 40 can include at least one bearing unit, and the two ends of each bearing unit can be respectively provided with a first fixing portion 42. Each first fixing portion 42 can be provided with a first fastening hole 421. Correspondingly, the hoop portion 31 of the clamp assembly 30 can include at least one hoop unit, and the two ends of each hoop unit can be respectively provided with a second fixing portion 32. The hoop unit and the bearing unit are arranged correspondingly.

[0059] In some embodiments, the fastening assembly 50 can include a stud bolt 51, a nut 52 and a self-locking washer 53.

[0060] Based on the above arrangement, when the nut 52 at the two ends is tightened, the corresponding self-locking washer 53 is pressed, and the second fixing part 32 is pressed by the self-locking washer 53, so that the second fixing part 32 at the two ends of the clamping part 31 is close to each other, thereby achieving the fastening of the clamp assembly 30, and the two first fixing parts 42 are clamped by the two second fixing parts 32, so that the two first fixing parts 42 are close to each other, thereby achieving the fastening of the mounting assembly 40.

[0061] In addition, by arranging the self-locking washer 53, the fastening torque of the nut 52 can be reduced, and the nut 52 can be prevented from loosening under vibration.

[0062] In some embodiments, the outer peripheral wall of the bearing part 41 is arranged flush with the outer peripheral wall of the clamping part 31, so that the size of the mounting assembly 40 in the radial direction of the manifold assembly is reduced, so that the outer peripheral wall of the bearing part 41 cannot protrude from the outer peripheral wall of the clamping part 31, thereby preventing the manifold assembly from being unable to be placed flat.

[0063] Of course, the outer peripheral wall of the bearing part 41 and the outer peripheral wall of the clamping part 31 do not exceed the maximum outer peripheral wall of the first pipe body 10 and the maximum outer peripheral wall of the second pipe body 20, so as to ensure that the manifold assembly can be placed flat.

[0064] In some embodiments, the manifold assembly can further include a sealing ring 60 arranged between the first connecting end 11 and the second connecting end 21. The sealing ring 60 can seal the gap between the first connecting end 11 and the second connecting end 21 to prevent fluid leakage from the first connecting end 11 and the second connecting end 21.

[0065] Optionally, the sealing ring 60 is provided with a tapered surface 61 at both ends along the axis direction thereof, one end of the tapered surface 61 is sealingly connected with the port of the first connecting end 11, and the other end of the tapered surface 61 is sealingly connected with the port of the second connecting end 21, so as to ensure that the port of the first connecting end 11 and the port of the second connecting end 21 are sealingly connected, thereby preventing fluid leakage.
