Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe production technology, specifically to an explosion-proof seamless steel pipe. Background Technology

[0002] Seamless steel pipes are steel pipes manufactured through processes such as hot rolling, cold drawing, or cold rolling. They are characterized by smooth inner and outer surfaces without obvious weld seams. Compared to welded steel pipes, seamless steel pipes have higher strength, pressure resistance, and corrosion resistance, making them suitable for fields with high requirements for pipeline quality and reliability. While the manufacturing process of seamless steel pipes is complex and production costs are higher, they have important applications in fields demanding high pipeline quality and reliability. When selecting seamless steel pipes, it is necessary to consider the actual needs of the project, the working environment, and load-bearing requirements to ensure the safety and reliability of the pipeline.

[0003] Existing seamless steel pipes are prone to bursting when the fluid pressure exceeds the set value, resulting in excessive damage to the pipe body and a large loss of fluid. To address this, we propose an explosion-proof seamless steel pipe. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof seamless steel pipe that can relieve fluid pressure, thereby solving the problem that existing seamless steel pipes are prone to bursting when the fluid pressure exceeds a set value, resulting in excessive damage to the pipe body and a large loss of fluid.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof seamless steel pipe, comprising a steel pipe body and ceramic balls, wherein a buffer groove is provided inside the steel pipe body near the outer surface, and pressure relief holes are provided at the top and bottom of the buffer groove inside the steel pipe body, with pressure relief pipes clamped inside the pressure relief holes, and ceramic balls are installed inside the buffer groove between the pressure relief pipes on both sides.

[0006] Preferably, there are four ceramic balls, which are respectively located at the top two sides and the bottom two sides of the buffer groove.

[0007] Preferably, a reinforcing ring is installed on the inner surface of the steel pipe body, and the reinforcing ring is arranged in a ring shape.

[0008] Preferably, a positioning boss is installed in the middle of one side of the steel pipe body, and a positioning groove is provided on the side of the steel pipe body away from the positioning boss, and the positioning boss is fitted into the positioning groove.

[0009] Preferably, a sealing gasket is installed at one end of the pressure relief pipe near the ceramic ball.

[0010] Preferably, the steel pipe body has a docking groove on the side near the positioning boss, a connecting groove on one side of the steel pipe body located on the docking groove side, and a connecting buckle on the side of the steel pipe body away from the docking groove. The connecting buckle can be snapped into the docking groove and the connecting groove.

[0011] Preferably, a connecting seat A is installed on the outer surface of the steel pipe body near the connecting buckle, and a connecting seat B is installed on the outer surface of the steel pipe body away from the connecting seat A. Both the connecting seat A and the connecting seat B are provided with bolt holes.

[0012] Preferably, a carbon fiber ring plate is installed inside the buffer groove, and a buffer liner is provided inside the buffer groove at the gap between the carbon fiber ring plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves the effect of relieving fluid pressure by setting pressure relief holes, pressure relief pipes, and ceramic balls. A buffer groove is provided inside the steel pipe body near the outer surface. Pressure relief holes are provided at the top and bottom of the buffer groove inside the steel pipe body. Pressure relief pipes are installed inside the pressure relief holes. Ceramic balls are placed in the gap between the pressure relief pipes on both sides inside the buffer groove. This solves the problem that existing seamless steel pipes are prone to bursting when the fluid pressure exceeds the set value, resulting in excessive damage to the pipe body and a large amount of fluid loss. This reduces the probability of seamless steel pipe bursting, thereby reducing the fluid loss rate.

[0015] 2. This utility model achieves the effect of conveniently connecting seamless steel pipes by setting up connecting seat A, connecting seat B, connecting buckle, butt groove, and connecting slot. A butt groove is provided on the side of the steel pipe body near the positioning boss, and a connecting slot is provided on the side of the steel pipe body located on the side of the butt groove. A connecting buckle is provided on the side of the steel pipe body away from the butt groove. Connecting seat A is provided on the outer surface of the steel pipe body near the connecting buckle, and connecting seat B is provided on the outer surface of the steel pipe body away from connecting seat A. Bolt holes are provided inside both connecting seat A and connecting seat B to solve the problem that the existing seamless steel pipes are all connected by bolts, resulting in poor connection strength and affecting the normal use of seamless steel pipes. This invention improves the connection strength of seamless steel pipes, thereby ensuring the normal use of seamless steel pipes.

[0016] 3. This utility model achieves the effect of supporting the inner wall of the seamless steel pipe by setting carbon fiber ring plates, reinforcing rings, and buffer linings. Reinforcing rings are set on the inner surface of the steel pipe body, carbon fiber ring plates are set inside the buffer groove, and buffer linings are set in the gaps between the carbon fiber ring plates inside the buffer groove. This solves the problem that the existing seamless steel pipes have low support strength and are prone to deformation and damage during fluid transportation. It reduces the probability of deformation of the seamless steel pipe and thus improves the service life of the seamless steel pipe. Attached Figure Description

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, to achieve the above objectives, this utility model provides the following technical solution: an explosion-proof seamless steel pipe, comprising a steel pipe body 1 and ceramic balls 13. A buffer groove 9 is provided inside the steel pipe body 1 near its outer surface. Pressure relief holes 14 are provided at the top and bottom of the buffer groove 9 inside the steel pipe body 1. Pressure relief pipes 15 are installed inside the pressure relief holes 14. Ceramic balls 13 are installed inside the buffer groove 9 between the pressure relief pipes 15 on both sides. A sealing gasket 12 is installed at one end of the pressure relief pipe 15 near the position of the ceramic ball 13. There are four ceramic balls 13 in total, located at the top two sides and the bottom two sides of the buffer groove 9. A reinforcing ring 11 is installed on the inner surface of the steel pipe body 1, and the reinforcing ring 11 is arranged in a ring shape. A carbon fiber ring plate 10 is installed inside the buffer groove 9. A buffer liner 16 is provided inside the buffer groove 9 between the carbon fiber ring plate 10. The buffer liner 16 absorbs the deformation force of the steel pipe body 1, thereby protecting the steel pipe body 1.

[0025] The working principle of an explosion-proof seamless steel pipe based on Embodiment 1 is as follows: After the present invention is installed, it is placed at the point of use. The fluid is transported through the steel pipe body 1, and the steel pipe body 1 is supported by the reinforcing ring 11, thereby improving the strength of the steel pipe body 1. The inner wall of the steel pipe body 1 is buffered and supported by the carbon fiber ring plate 10, thereby protecting the steel pipe body 1. When the fluid pressure inside the steel pipe body 1 is too high, the ceramic ball 13 is squeezed. The excessive squeezing force causes the ceramic ball 13 to break, thereby connecting the pressure relief pipe 15 and discharging the fluid through the pressure relief pipe 15, thus protecting the steel pipe body 1. At this point, the working process of the equipment is completed.

[0026] Example 2

[0027] like Figure 1 and Figure 2 As shown, the explosion-proof seamless steel pipe proposed in this utility model, compared with Embodiment 1, further includes: a positioning boss 6 installed in the middle of one side of the steel pipe body 1, a positioning groove 7 provided on the side of the steel pipe body 1 away from the positioning boss 6, the positioning boss 6 being fitted into the positioning groove 7, and the steel pipe body 1 being connected by the positioning boss 6 and the positioning groove 7; a docking groove 3 provided on the side of the steel pipe body 1 near the positioning boss 6, a connecting groove 4 provided on the side of the steel pipe body 1 located in the docking groove 3, a connecting buckle 8 provided on the side of the steel pipe body 1 away from the docking groove 3, the connecting buckle 8 being fitted into the docking groove 3 and the connecting groove 4, and the steel pipe body 1 being fixed by the connecting buckle 8 and the connecting groove 4; a connecting seat A2 installed on the outer surface of the steel pipe body 1 near the connecting buckle 8, and a connecting seat B5 installed on the outer surface of the steel pipe body 1 away from the connecting seat A2; bolt holes are provided inside both the connecting seat A2 and the connecting seat B5.

[0028] In this embodiment, when it is necessary to connect the steel pipe body 1, the positioning boss 6 is installed inside the positioning groove 7, and the connecting buckle 8 is installed inside the docking groove 3. Then, the steel pipe body 1 is rotated and the connecting buckle 8 is installed inside the connecting groove 4. After completion, the two steel pipe bodies 1 are connected by bolts and bolt holes, so that fluid can be transported through the steel pipe body 1.

[0029] The above specific embodiments are merely several preferred embodiments of this utility model.
