Steel pipe, as the main strength part, is composited with other materials such as polymer materials, fiberglass, etc., and has the characteristics of high strength, high durability, corrosion resistance, and wear resistance. Advantages of composite steel pipe: 1. High strength: The steel shell of the composite steel pipe has high strength and can withstand greater pressure and impact. The mechanical properties of composite materials are better, which can make up for the defects of a single material. 2. Good corrosion resistance: The internal material of the composite steel pipe can be selected according to the characteristics of the medium, and it has good corrosion resistance for pipes containing certain corrosive media. 3. Wear resistance: The composite steel pipe can use the wear-resistant layer of the material or the lining method for wear protection. 4. Long service life: The use of composite materials can effectively extend the service life of the pipeline, reduce the frequency of maintenance and replacement, and reduce maintenance costs. 5. Good insulation performance: According to the characteristics of the medium, materials with better insulation can be selected as needed, and it has a wide range of applications in fields such as energy transportation. Application scenarios of composite steel pipes, composite steel pipes have a wide range of application scenarios in the fields of petroleum, chemical industry, rail transportation, etc. 1. Petroleum industry: oil pipelines and water injection pipelines. These pipelines have very high requirements for acid resistance, corrosion resistance, high pressure resistance, and high temperature resistance. Composite steel pipes can meet these requirements. 2. Chemical industry: In the fields of transporting chemicals, storage tanks, reactors, etc., the properties of composite materials can meet many requirements and show excellent performance in corrosion resistance, acid and alkali resistance, etc. 3. Rail transit: In the fields of high-speed railways and urban rail transit, the lightweight characteristics of composite pipes can reduce the weight of railway vehicles and reduce energy consumption. The market prospects of composite steel pipes, with the acceleration of the globalization process and the increase in environmental protection requirements of various countries, composite pipes have been more and more widely used, and can replace traditional metal pipes in some industries. Especially in the petroleum, chemical and other industries, the demand for pipelines is still on a growing trend. However, when defects occur on the surface of the steel pipe, the defect position cannot be directly observed with the naked eye. In order to solve this problem, a composite steel pipe defect detection device has emerged, which is used to detect and process the defect position, find the defect position, and facilitate subsequent repair. However, the existing steel pipe defect detection device lacks the effect of rotating the steel pipe when detecting the steel pipe, and the existing steel pipe surface defect detection device has certain limitations on the detection range, so that its detection range is small and it is easy to miss the detection phenomenon. Therefore, a composite steel pipe defect detection device is proposed. Utility Model Content
