Winding three-layer PE anticorrosive steel pipe body.
1. Introduction to winding three-layer PE anticorrosive steel pipe.
Winding three-layer PE anti-corrosion steel pipe is a new type of anti-corrosion steel pipe, its structure is composed of three layers, the inner layer is the anti-corrosion layer, the outer layer is the anti-rust layer, and the middle layer is the reinforced layer. This kind of steel pipe is made of polymer polyethylene (PE) material, which has excellent corrosion resistance and mechanical properties, and is widely used in petroleum, chemical industry, electric power, shipbuilding, seawater desalination, food, medicine and other fields.
2. The advantages of winding three-layer PE anti-corrosion steel pipe.
1.Strong corrosion resistance: Due to the use of polymer polyethylene (PE) material, the spiral wound three-layer PE anti-corrosion steel pipe has excellent corrosion resistance, which can resist the erosion of a variety of chemical media and effectively prolong the service life of the pipeline.
2.Excellent mechanical properties: The steel pipe has high strength and toughness, can withstand large pressure and bending stress, and is not prone to cracking, deformation and other problems.
3.Good anti-rust performance: the existence of the outer anti-rust layer effectively avoids the problem of rust in the process of transportation and use of the steel pipe.
4.Easy installation: The steel pipe is light in weight, easy to transport, and easy to install, which can greatly shorten the construction period and reduce the project cost.
5.Long service life: Due to its excellent corrosion resistance and mechanical properties, the spiral wound three-layer PE anti-corrosion steel pipe has a long service life and low long-term maintenance cost.
3. Application field of spiral three-layer PE anticorrosive steel pipe.
1.Oil and gas transportation: Due to its excellent corrosion resistance and mechanical properties, winding three-layer PE anti-corrosion steel pipes are widely used in oil and gas transmission pipeline projects.
2.Chemical pipelines: In the process of chemical production, the anti-corrosion performance of pipelines is extremely high, and the winding three-layer PE anti-corrosion steel pipe can meet this demand and improve the safety and stability of production.
3.Electric power field: In the electric power field, the steel pipe can be used for cable protection pipes, transformer pipes, etc., to improve the service life and safety of power facilities.
4.Shipbuilding: The problem of corrosion in the ship piping system has always been a problem in the industry, and the application of winding three-layer PE anti-corrosion steel pipe can effectively solve this problem.
5.Seawater desalination: In the field of seawater desalination, the steel pipe can be used for freshwater transportation pipelines, seawater pipelines, etc., to improve the corrosion resistance and safety of the water transmission system.
6.Food and medicine: In the food and pharmaceutical industry, the winding three-layer PE anticorrosive steel pipe can be used to transport drinking water, medicines, etc., to ensure the quality and safety of products.
Fourth, the production process of winding three-layer PE anticorrosive steel pipe.
The production process of spiral wound three-layer PE anticorrosive steel pipe mainly includes the following steps:
1.Pipe selection and pretreatment: select the appropriate pipe according to different application fields and requirements, and carry out pretreatment of the inner and outer surfaces to remove oil stains, impurities, etc.
2.Inner anti-corrosion layer coating: A layer of polymer polyethylene (PE) material is coated on the surface of the inner tube to form a uniform and smooth anti-corrosion layer.
3.Middle reinforcement layer winding: Wrap one or more layers of high-strength glass fiber cloth or steel wire outside the anti-corrosion layer to enhance the mechanical properties of the anti-corrosion layer.
4.Coating of the outer anti-rust layer: Coating, another layer of anti-rust material is applied outside the reinforcing layer to prevent the steel pipe from corroding during transportation and use.
5.Testing and packaging: Conduct quality inspection of finished products, such as appearance, size, coating thickness, etc., and package them out of the factory after they are qualified.
5. The development trend of winding three-layer PE anticorrosive steel pipe.
With the continuous improvement of environmental awareness and the continuous progress of technology, the application prospect of winding three-layer PE anticorrosive steel pipe is getting broader and broader. In the future, the steel pipe will be further developed in the following aspects:
1.Application of environmentally friendly materials: the use of environmentally friendly anti-corrosion materials and anti-rust materials to reduce pollution and damage to the environment.
