[0001] The invention relates to the technical field of seamless steel pipes for ships, in particular to a stainless steel high-strength seamless steel pipe for ships. Background Art

[0002] Ship seamless steel pipe refers to seamless steel pipe specially used in shipbuilding process. The specification range of this steel pipe is very wide, the outer diameter can range from 8mm to 1240mm, and the wall thickness can range from 1mm to 200mm. The material of ship seamless steel pipe can be stainless steel. This material of steel pipe is used in the process of ship construction and maintenance because it has high strength and corrosion resistance and can meet the use requirements of ships in complex marine environments. The pipeline system on the ship also involves some special-purpose seamless steel pipes, which are used to withstand liquid pressure and undergo water pressure tests. They are specially used to transport oil, natural gas, coal gas, water and certain solid materials. The application of these steel pipes further expands the function and application scope of the ship pipeline system.

[0003] Existing seamless steel pipes for ships are often assembled between steel pipes for extension during use, so the pressure bearing capacity of the assembly position is weak. Under long-term fluid impact, the assembly position is very easy to loosen and separate, thus affecting subsequent use. For this reason, we propose a stainless steel high-strength seamless steel pipe for ships. Summary of the invention

[0004] The object of the present invention is to provide a high-strength stainless steel seamless pipe for ships, so as to solve the problem proposed in the above-mentioned background technology that the existing seamless steel pipes for ships are often assembled between steel pipes for extension during use, so the pressure bearing capacity of the assembly position is weak, and under long-term fluid impact, the assembly position is very easy to loosen and separate, thereby affecting subsequent use.

[0005] To achieve the above object, the present invention provides the following technical solution: a high-strength stainless steel seamless steel pipe for ships, comprising a ship steel pipe body, a buffer mechanism is provided inside one end of the ship steel pipe body, and a protective component is provided outside the ship steel pipe body;

[0006] The buffer mechanism comprises a buffer ring frame, which is fitted to the inner side of one end of the ship steel pipe body, a plurality of arc grooves are evenly arranged in an annular shape inside the buffer ring frame, a clamping frame is fixed outside the buffer ring frame, and a rubber sleeve is movably sleeved outside the buffer ring frame.

[0007] Preferably, a card slot is provided on the inner side of the ship steel pipe body, and the card frame and the rubber sleeve are both engaged in the card slot.

[0008] Preferably, the buffer ring frame forms a buffer structure through a clamping frame, a rubber sleeve and a ship steel pipe body.

[0009] Preferably, the ship steel pipe body comprises a pipe body, a group of flange seats 1 are symmetrically fixedly provided at both ends of the pipe body, a hollow frame is fixedly sleeved on the outside of the pipe body close to the buffer mechanism, and a flange seat 2 is fixedly connected to the outside of the hollow frame.

[0010] Preferably, the second flange seat is fixedly sleeved on the outside of the hollow frame, and the hollow frame has the same thickness as the second flange seat.

[0011] Preferably, the protection component includes a protection tube, which is arranged outside the ship steel pipe body, one end of the protection tube is fixedly connected to a flange seat three, a plurality of limit grooves are evenly opened on the inner side of the protection tube, and a limit strip is engaged inside the limit groove.

[0012] Preferably, the protection tube and the flange seat three are integrally formed, and the flange seat three and the flange seat two are in close contact with each other.

[0013] Preferably, a plurality of the limit strips are fixedly connected to the tube body, and the tube body forms a snap-fit ​​structure through the limit strips and the limit grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, when the fluid contacts the buffer ring frame, the buffer ring frame drives the clamp frame to move backward to squeeze the rubber sleeve, and the impact force is transferred to the rubber sleeve. The rubber sleeve produces corresponding deformation to effectively disperse and absorb the impact force. At the same time, the several arc grooves on the inner side of the buffer ring frame effectively increase the flow path, so that the speed of the fluid inside the buffer ring frame is slowed down, the impact damage of the fluid on the end of the tube body is reduced, and the possibility of loose separation of the assembly position of the tube body is reduced.

[0016] 2. In the present invention, flange seat 1 cooperates with fasteners for assembly between adjacent ship steel pipe bodies, and flange seat 2 cooperates with fasteners for connection with the protective component, so that the protective component is stably limited outside the pipe body to protect the pipe body and reduce collision damage to the pipe body by external objects. When flange seat 2 is connected to the protective component, the hollow frame effectively avoids sealing at one end of the protective component, so that the heat generated by the fluid inside the pipe body can be dissipated through both ends of the protective component, thereby improving the heat dissipation efficiency.

[0017] 3. The present invention can quickly sleeve the protective tube onto the outside of the tube body through the cooperation between the limiting groove and the limiting strip. At the same time, the mounting holes on the inner sides of the flange seat 2 and the flange seat 3 also correspond one to one, thereby improving the assembly efficiency between the protective tube and the tube body. After the assembly is completed, there is still heat dissipation space between the protective tube and the tube body, so that the protective tube can protect the tube body without affecting the heat dissipation of the fluid inside the tube body.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-3The present invention provides a technical solution: a stainless steel high-strength seamless steel pipe for ships, comprising a ship steel pipe body 1, a buffer mechanism 2 is provided on the inner side of one end of the ship steel pipe body 1, and a protective component 3 is provided on the outside of the ship steel pipe body 1; the ship steel pipe body 1 comprises a pipe body 101, a group of flange seats 102 are symmetrically fixedly provided at both ends of the pipe body 101, a hollow frame 103 is fixedly provided on the outside of one side of the pipe body 101 close to the buffer mechanism 2, and a flange seat 2 104 is fixedly connected to the outside of the hollow frame 103, wherein the flange seat 2 104 is fixedly provided on the outside of the hollow frame 103, and the hollow frame 103 and the flange seat 2 104 have the same thickness. In the present invention, flange seat 102 cooperates with fasteners for assembling adjacent ship steel pipe bodies 1, and flange seat 2 104 cooperates with fasteners for connecting with protection component 3, so that protection component 3 is stably limited outside pipe body 101, protecting pipe body 101 and reducing collision damage to pipe body 101 by external objects. When flange seat 2 104 is connected to protection component 3, hollow frame 103 effectively avoids sealing at one end of protection component 3, so that the heat generated by the fluid inside pipe body 101 can be dissipated through both ends of protection component 3, thereby improving heat dissipation efficiency.

[0027] The protection component 3 includes a protection tube 301, which is arranged on the outside of the ship steel pipe body 1. One end of the protection tube 301 is fixedly connected to a flange seat three 302, wherein the protection tube 301 and the flange seat three 302 are integrally formed, the flange seat three 302 and the flange seat two 104 are in contact with each other, and a plurality of limit grooves 303 are evenly opened on the inner side of the protection tube 301, and the limit strips 304 are engaged inside the limit grooves 303. Furthermore, the plurality of limit strips 304 are fixedly connected to the tube body 101, and the tube body 101 forms a locking structure with the limit strips 304 and the limit grooves 303. The present invention can quickly sleeve the protection tube 301 on the outside of the tube body 101 through the cooperation between the limiting groove 303 and the limiting strip 304. At the same time, the flange seat 2 104 and the mounting holes on the inner side of the flange seat 302 also correspond one to one, thereby improving the assembly efficiency between the protection tube 301 and the tube body 101. After the assembly is completed, there is still heat dissipation space between the protection tube 301 and the tube body 101, so that the protection tube 301 can protect the tube body 101 without affecting the heat dissipation of the fluid inside the tube body 101.

[0028] See also Figure 4-6The present invention provides a technical solution: a stainless steel high-strength seamless steel pipe for ships, the buffer mechanism 2 includes a buffer ring frame 201, the buffer ring frame 201 is attached to the inner side of one end of the ship steel pipe body 1, a plurality of arc grooves 202 are evenly arranged in an annular shape inside the buffer ring frame 201, a clamping frame 203 is fixed to the outside of the buffer ring frame 201, and a rubber sleeve 204 is movably sleeved on the outside of the buffer ring frame 201, wherein a clamping groove is opened on the inner side of the ship steel pipe body 1, and the clamping frame 203 and the rubber sleeve 204 are both clamped in the inside of the clamping groove, and further, the buffer ring frame 201 forms a buffer structure with the ship steel pipe body 1 through the clamping frame 203 and the rubber sleeve 204. In the present invention, when the fluid contacts the buffer ring frame 201, the buffer ring frame 201 drives the bracket 203 to move backward to squeeze the rubber sleeve 204, and the impact force is transferred to the rubber sleeve 204. The rubber sleeve 204 produces corresponding deformation to effectively disperse and absorb the impact force. At the same time, the several arc grooves 202 on the inner side of the buffer ring frame 201 effectively increase the flow path, so that the speed of the fluid inside the buffer ring frame 201 is slowed down, reducing the impact damage of the fluid on the end of the tube body 101, and reducing the possibility of loose separation of the assembly position of the tube body 101.

[0029] Working principle: The protection tube 301 can be quickly sleeved on the outside of the tube body 101 through the cooperation between the limiting groove 303 and the limiting strip 304. At the same time, the flange seat 2 104 and the mounting holes on the inner side of the flange seat 302 also correspond one to one. The flange seat 2 104 and the flange seat 3 302 can be connected by fasteners, so that the protection component 3 is stably limited on the outside of the tube body 101 to protect the tube body 101 and reduce the collision damage of external objects to the tube body 101. When the flange seat 2 104 and the flange seat 3 302 are connected, the hollow frame 103 prevents one end of the protection component 3 from being sealed, so that the heat generated by the fluid inside the tube body 101 can be released through the gap between the protection tube 301 and the tube body 101. The heat dissipation space and the two ends diverge to improve the heat dissipation efficiency. The flange seat 102 is matched with the fasteners for assembly between adjacent ship steel pipe bodies 1. After the assembly is completed, the fluid begins to transmit. When the fluid contacts the buffer ring frame 201, the buffer ring frame 201 drives the bracket 203 to move backward to squeeze the rubber sleeve 204, and the impact force is transferred to the rubber sleeve 204. The rubber sleeve 204 produces corresponding deformation to disperse and absorb the impact force. At the same time, the several arc grooves 202 on the inner side of the buffer ring frame 201 increase the flow path, so that the speed of the fluid inside the buffer ring frame 201 is slowed down, reducing the impact damage of the fluid on the end of the pipe body 101, and reducing the possibility of loose separation of the assembly position of the pipe body 101.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
