Technical Field
[0001] This utility model relates to the field of oil pipeline technology, and in particular to an oil transportation pipeline. Background Technology
[0002] Oil pipelines are pipeline systems used to transport oil and petroleum products. They are one of the main pieces of equipment in the oil storage and transportation industry, and the most important equipment for transporting crude oil and petroleum products. Oil pipelines are generally made of steel pipes, a material with high strength, good toughness, and weldability, capable of withstanding the pressure and stress generated during transportation.
[0003] Oil pipelines are often connected by welding. The welded joints at the pipe ends lack additional protection and long-term effective protection, making them prone to problems such as rust and corrosion. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide an oil transportation pipeline to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of the present invention provides an oil transportation pipeline, including a pipe body and pipe openings, wherein the pipe body is fixedly connected to the pipe openings at both ends; The pipe wall consists of an anti-corrosion layer, a pipe body, and an insulation layer from the inside out. The outer surface of the pipe body is covered with an insulation layer, and the inner side of the pipe body is coated with an anti-corrosion layer. A socket is fixedly connected to one end of the outer surface of the tube, and the inner side of the socket is provided with anti-slip texture. A protective layer is fixedly connected to the outer surface of the tube near the other end. The adjacent tube openings are welded together. The protective layer covers the connection of the tube openings. The end of the protective layer is inserted into the socket. The end of the protective layer is inserted into the inside of the socket and then fixedly connected.
[0007] Preferably, in any of the above schemes, the pipe body and the pipe opening are integrally formed, and the pipe body and the two pipe openings at both ends together form a pipe segment.
[0008] The above technical solution is adopted: In this oil pipeline, a single pipe section consists of a pipe body, pipe ends, additional spigots, and a protective layer structure. The pipe ends of the pipe sections are welded together to form the entire oil pipeline.
[0009] The pipe body consists of an asphalt anti-corrosion layer, a carbon steel pipe body, and a polyethylene plastic insulation layer from the inside out.
[0010] The insulation layer is used to prevent corrosive chemicals in the soil from eroding the pipeline body; the pipeline is wrapped with an insulation layer.
[0011] The anti-corrosion layer reduces the corrosion of the pipeline by the transported oil itself and improves the smoothness of the pipeline, thereby increasing the transport capacity.
[0012] Preferably, of any of the above schemes, the anti-corrosion layer is an asphalt layer, and the pipe body is made of carbon steel.
[0013] The above technical solution utilizes a device with the following core structure: a spigot, anti-slip texture, and a protective layer. A spigot is fixedly connected to one end of the outer surface of the pipe body, used to mate with the protective layer at the other end. The inner side of the spigot has anti-slip texture to increase friction during mating. The protective layer is made of synthetic rubber, a soft material that initially rolls up onto the pipe body. After welding between the pipe ends, it unfolds, covering and adhering to part of the pipe body and the outer surface of the welded joint. The protective layer is made of rubber, rubber foam, porous polymer, and fiberglass, possessing strong weather resistance, moisture resistance, and heat insulation properties. It effectively provides additional protection for the welded joint, maintaining stable performance and resisting aging, cracking, or detachment, ensuring long-term effective protection of the pipeline weld. This prevents problems such as rust and corrosion at the welded joint of the oil pipeline. Preferably, in any of the above embodiments, the insulating layer is made of polyethylene plastic, and the socket is heat-fused to the tube body.
[0014] Preferably, the protective layer is a soft structure, the material of the protective layer is synthetic rubber, and the protective layer is made of rubber, rubber foam, porous polymer, or glass fiber.
[0015] Preferably, in any of the above embodiments, the protective layer is thermally fused to the outer surface of the pipe body, and the port of the protective layer is bonded or thermally fused to the inner side of the socket.
[0016] Preferably, in any of the above embodiments, the protective layer covers the outer surface of the fitting portion of the tube and the outer surfaces of the two tube openings.
[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This oil pipeline utilizes a combination of a spigot, anti-slip texture, and a protective layer. A spigot is fixedly connected to one end of the outer surface of the pipe body, aligning with the protective layer at the other end. The inner side of the spigot has anti-slip texture to increase friction during connection. The protective layer is made of synthetic rubber, a soft material that initially rolls up onto the pipe body. After welding between the pipe ends, it unfolds, covering and adhering to a portion of the pipe body and the outer surface of the welded joint. The protective layer is made of rubber, rubber foam, porous polymer, and fiberglass, possessing strong weather resistance, moisture resistance, and heat insulation properties. It effectively provides additional protection to the welded joint, maintaining stable performance and resisting aging, cracking, or detachment, ensuring long-term effective protection of the pipeline welds and preventing rust and corrosion at the oil pipeline welds.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] like Figure 1-4 As shown, this oil pipeline includes a pipe body 1 and pipe openings 2, with pipe openings 2 fixedly connected to both ends of the pipe body 1. The pipe wall of the pipe body 1 consists of an anti-corrosion layer 101, a pipe body 102 and an insulation layer 103 from the inside to the outside. The outer surface of the pipe body 102 is covered with the insulation layer 103, and the inner side of the pipe body 102 is coated with the anti-corrosion layer 101. A socket 3 is fixedly connected to one end of the outer surface of the tube body 1, and anti-slip texture 4 is provided on the inner side of the socket 3. A protective layer 5 is fixedly connected to the outer surface of the pipe body 1 near the other end. The adjacent pipe openings 2 are welded together. The protective layer 5 covers the connection of the pipe openings 2. The end of the protective layer 5 is inserted into the socket 3. The end of the protective layer 5 is inserted into the inside of the socket 3 and then fixedly connected.
[0024] Example 1: The pipe body 102 and the pipe opening 2 are integrally formed, and the pipe body 1 and the two pipe openings 2 at both ends together form a pipe segment. In this oil pipeline, a single pipe segment consists of a pipe body 1, pipe openings 2 at both ends, additional spigots 3, and a protective layer 5. The pipe openings 2 of the pipe segments are welded together to form the entire oil pipeline. The pipe body 1 consists of an asphalt anti-corrosion layer 101, a carbon steel pipe body 102, and a polyethylene plastic insulation layer 103 from the inside out. The insulation layer 103 prevents corrosive chemical components in the soil from eroding the pipeline body, and the pipeline is wrapped with an insulation layer 103.
[0025] The anti-corrosion layer 101 reduces the corrosion of the pipeline by the transported oil itself and improves the smoothness of the pipeline, thereby increasing the transport capacity.
[0026] Example 2: The anti-corrosion layer 101 is specifically an asphalt layer, and the pipe body 102 is made of carbon steel. The insulation layer 103 is made of polyethylene plastic, and the spigot 3 is heat-fused to the pipe body 1. The protective layer 5 is a flexible structure made of synthetic rubber, and is composed of rubber, rubber foam, porous polymer, and glass fiber. The protective layer 5 is heat-fused to the outer surface of the pipe body 1, and the port of the protective layer 5 is bonded or heat-fused to the inner side of the spigot 3. The protective layer 5 covers and adheres to the outer surface of the portion of the pipe body 1 and the outer surfaces of the two pipe ports 2. The rubber foam and porous polymer components in the protective layer 5 have good thermal insulation properties, which can reduce the temperature exchange between the inside and outside of the pipeline to a certain extent, help maintain the stable temperature of the oil inside the pipeline, and reduce changes in oil properties or pipeline stress caused by temperature changes.
[0027] The working principle of this utility model is as follows: This oil pipeline consists of a pipe body 1, pipe ends 2, additional spigots 3, and a protective layer 5 in a single pipe section. The pipe ends 2 of the pipe sections are welded together to form the entire oil pipeline.
[0028] The pipe body 1 consists of an asphalt anti-corrosion layer 101, a carbon steel pipe body 102, and a polyethylene plastic insulation layer 103, from the inside out.
[0029] Among them, the insulation layer 103 prevents corrosive chemical components in the soil from eroding the pipeline body; The anti-corrosion layer 101 reduces the corrosion of the pipeline by the transported oil itself and improves the smoothness of the pipeline, thereby increasing the transport capacity. The protective layer 5 is made of synthetic rubber, which is a soft material. Initially, it is rolled up on the tube body 1. After the welding between the tube openings 2 is completed, it is unfolded to cover and adhere to part of the tube body 1 and the outer surface of the welded joint of the tube opening 2. The end of the protective layer 5 is inserted into the socket 3 and then further bonded and fixed with glue, which can effectively provide additional protection for the welded joint of the tube opening 2.
[0030] Compared with the prior art, the present invention has the following advantages: This oil pipeline, through the coordinated arrangement of spigot 3, anti-slip texture 4, and protective layer 5, has a spigot 3 fixedly connected to one end of the outer surface of the pipe body 1. The spigot 3 is used to mate with the protective layer 5 at the other end. The inner side of the spigot 3 has anti-slip texture 4 to increase the friction during mating. The protective layer 5 is made of synthetic rubber, a soft material. Initially, it is rolled up on the pipe body 1. After the pipe ends 2 are welded, it unfolds, covering and adhering to part of the pipe body 1 and the outer surface of the welded joint of the pipe ends 2. The protective layer 5 is made of rubber, rubber foam, porous polymer, and fiberglass, possessing strong weather resistance, moisture resistance, and heat insulation properties. It can effectively provide additional protection for the welded joint of the pipe ends 2. The protective layer 5 maintains stable performance and is not prone to aging, cracking, or falling off, ensuring long-term effective protection of the pipeline welded joint and preventing problems such as rust and corrosion at the oil pipeline welded joint.
