The following is the body of an article about "Three-layer PE anticorrosive spiral steel pipe for clad water supply pipeline" for your reference:
Three-layer PE anti-corrosion spiral steel pipe for clad water supply pipeline is a special pipeline material, which has excellent anti-corrosion performance and long service life. Due to its wide range of application fields and growing market demand, three-layer PE anti-corrosion spiral steel pipe has become an important part in the field of water supply pipelines.
1. The structure and characteristics of three-layer PE anticorrosive spiral steel pipe.
The three-layer PE anti-corrosion spiral steel pipe is composed of an inner layer, an intermediate layer and an outer layer. The inner layer is an anti-corrosion coating, which mainly prevents corrosion and wear inside the pipeline; The middle layer is the adhesive layer, which plays a role in enhancing the overall performance of the pipeline; The outer layer is an anti-aging layer, which can effectively resist the influence of the external environment and aging factors on the pipeline. The three-layer PE anticorrosive spiral steel pipe has the following characteristics:
1.Excellent anti-corrosion performance: The inner anti-corrosion coating of the three-layer PE anti-corrosion spiral steel pipe can effectively prevent the corrosion inside the pipeline, and the outer anti-aging layer can effectively resist the erosion of the external environment and prolong the service life of the pipeline.
2.High strength and good pressure resistance: The three-layer PE anti-corrosion spiral steel pipe uses high-quality steel pipe as the base material, which has high mechanical properties and compressive strength, and can withstand high water pressure and strong fluid impact.
3.Easy installation: The connection method of the three-layer PE anti-corrosion spiral steel pipe is simple and reliable, and can be welded, flanged and other methods, and the installation speed is fast, which can effectively shorten the project cycle.
4.Long life: Due to the excellent anti-corrosion performance and anti-aging performance of the three-layer PE anti-corrosion spiral steel pipe, its service life is long, up to more than 50 years, which can greatly reduce the maintenance cost.
The application field of two- and three-layer PE anticorrosive spiral steel pipes.
Three-layer PE anticorrosive spiral steel pipes are widely used in water supply, drainage, sewage treatment, heat, gas and other fields. In the field of water supply, due to its excellent anti-corrosion performance and compressive strength, it can effectively ensure the safety and quality of water supply; In the field of drainage, due to its strong compressive strength and corrosion resistance, it can effectively solve the problem of sewage discharge and treatment; In the field of gas, due to its good sealing performance and aging resistance, it can ensure the safe transportation and use of gas.
3. The production process of three-layer PE anticorrosive spiral steel pipe.
The production process of three-layer PE anticorrosive spiral steel pipe mainly includes the following steps:
1.Base material selection: high-quality steel pipe is selected as the base material to ensure the mechanical properties and compressive strength of the pipe.
2.Inner anti-corrosion coating coating: Advanced coating technology is used to apply an inner layer of anti-corrosion coating on the substrate to prevent corrosion inside the pipeline.
3.Intermediate adhesive layer coating: The middle adhesive layer is applied to the inner anti-corrosion coating to enhance the overall performance of the pipeline.
4.Coating of the outer anti-aging layer: The outer anti-aging layer is coated on the adhesive layer of the middle layer to improve the weather resistance and service life of the pipeline.
5.Quality inspection: Strict quality inspection is carried out on the production of three-layer PE anticorrosive spiral steel pipes to ensure that the product quality meets the relevant standards.
6.Packing and leaving the factory: Packing and leaving the factory for qualified products for customers' use.
