With the continuous development of industry, pipelines are more and more widely used in various fields, and the market demand for anti-corrosion spiral pipes, as one of them, is also increasing. As a new type of anti-corrosion spiral pipe, the three-layer polyethylene coated anti-corrosion spiral pipe has excellent anti-corrosion performance and long service life, so it is favored in the market. This article will focus on the characteristics and advantages of three-layer polyethylene coated anticorrosive spiral pipe, and analyze its production process in detail.
1. Characteristics of three-layer polyethylene-coated anticorrosive spiral pipe.
Three-layer polyethylene coated anti-corrosion spiral pipe is a new type of anti-corrosion spiral pipe, which is made of high-density polyethylene material for the outer layer, modified polypropylene material for the middle layer, and food-grade epoxy resin material for the inner layer. This special combination of materials makes the anti-corrosion spiral tube have excellent anti-corrosion properties, weather resistance and mechanical properties. At the same time, the three-layer polyethylene coated anti-corrosion spiral pipe also has good insulation performance, flame retardant performance and environmental protection performance, and can work stably for a long time under various complex environmental conditions.
Advantages of two- and three-layer polyethylene-coated anti-corrosion spiral pipes.
1.Excellent anti-corrosion performance: The three-layer polyethylene-coated anti-corrosion spiral pipe adopts a special combination of materials, which can effectively resist the corrosion of acids, alkalis, salts and other chemicals, and prolong the service life of the pipeline.
2.Strong weather resistance: This anti-corrosion spiral pipe can work normally in the environment of -30 80 and is not affected by climate change.
3.Excellent mechanical properties: the three-layer polyethylene coated anti-corrosion spiral pipe has high strength and toughness, and can withstand large pressure and bending stress.
4.Good insulation performance: The insulation performance of the pipeline can effectively reduce the waste of energy and the damage of equipment.
5.Strong flame retardant performance: The anti-corrosion spiral pipe has high flame retardant performance, which can effectively prevent the occurrence and spread of fire.
6.Good environmental performance: The three-layer polyethylene coated anti-corrosion spiral pipe is made of environmentally friendly materials, which will not cause pollution to the environment.
3. Production process of three-layer polyethylene coated anticorrosive spiral pipe.
The production process of three-layer polyethylene coated anticorrosive spiral pipe mainly includes the following steps:
1.Pipe selection and treatment: select pipes of appropriate specifications and materials according to needs, and clean and pretreat the inner and outer surfaces to ensure that the cleanliness and roughness of the pipe surface meet the requirements.
2.Coating anti-corrosion layer: Coating a layer of anti-corrosion coating on the outer surface of the pipe can effectively improve the anti-corrosion performance and service life of the pipe.
3.Polyethylene coating: The coated pipe is placed into a three-layer polyethylene coating machine for coating to form a polyethylene protective layer with three layers of outer layer, middle layer and inner layer. This step is a critical part of the production process and requires strict control of parameters such as temperature, pressure and time to ensure that the thickness and quality of the polyethylene cladding meet the requirements.
4.Cooling and shaping: The polyethylene cladding is fixed by cooling and shaping, and the shape and size of the pipe are stabilized.
5.Quality inspection and packaging: Carry out quality inspection on the production of anti-corrosion spiral tubes, such as appearance, size, thickness and performance. Qualified products are packaged and waiting for factory sales.
