This article will focus on the characteristics, production process and practical application of 3PE coated anticorrosive spiral steel pipe.
1. Characteristics of 3PE coated anticorrosive spiral steel pipe.
3PE coated anti-corrosion spiral steel pipe is composed of steel pipe substrate, epoxy powder, polyethylene and other materials, through advanced production technology, the layers of materials are tightly combined to form a high-performance anti-corrosion layer. Its main features are as follows:
1.Excellent anti-corrosion performance: The anti-corrosion layer of 3PE-coated anti-corrosion spiral steel pipe has excellent corrosion resistance, which can effectively resist the corrosion of acid, alkali, salt, oxidant and other chemical media, and has a long service life.
2.Good mechanical properties: The anti-corrosion layer of 3PE-coated anti-corrosion spiral steel pipe has high hardness and good impact resistance, which can withstand large pressure and friction and is not easy to damage.
3.Stable electrical properties: The anti-corrosion layer of 3PE-coated anti-corrosion spiral steel pipe has good insulation performance and stable electrical properties, which can ensure the safety and reliability of the pipeline during use.
4.Environmental protection and safety: The anti-corrosion layer of 3PE-coated anti-corrosion spiral steel pipe is non-toxic and tasteless, harmless to the environment, and meets environmental protection requirements. At the same time, no toxic and harmful chemicals are used in the production process, which is harmless to the human body.
5.Wide range of application: 3PE coated anti-corrosion spiral steel pipe is suitable for pipeline systems in various corrosive environments, such as oil, natural gas, chemical industry, urban water supply and drainage and other fields.
Second, the production process of 3PE coated anticorrosive spiral steel pipe.
The production process of 3PE coated anticorrosive spiral steel pipe mainly includes the following steps:
1.Pipe preparation: select high-quality steel pipe as the base material, and carry out pretreatment work such as rust removal and oil removal to ensure that the cleanliness and roughness of the surface of the substrate meet the requirements.
2.Pre-heat treatment: The pre-treated steel pipe is preheated to increase the adhesion of the powder and improve the adhesion of the coating.
3.Coating epoxy powder: The epoxy powder is applied to the preheated steel pipe to form a dense epoxy coating, which has good corrosion resistance and mechanical properties.
4.Polyethylene coating: An additional layer of polyethylene is applied on top of the epoxy coating to increase the wear and impact resistance of the anti-corrosion layer.
5.Cooling treatment: The coated steel pipe is cooled to make it quickly set and improve the stability and hardness of the coating.
6.Quality inspection: Strict testing of finished products is carried out to ensure that their performance indicators meet the requirements.
3. Practical application of 3PE coated anticorrosive spiral steel pipe.
3PE coated anticorrosive spiral steel pipe has a wide range of application fields in practical applications. In the field of oil and gas, it can be used to transport oil, natural gas and other fluid media, effectively preventing pipeline corrosion and leakage;In the chemical field, it can be used to transport various corrosive liquids and gases to ensure safety and reliability in the production processIn the field of urban water supply and drainage, it can be used to transport fluid media such as drinking water and sewage to ensure the safety and hygiene of water quality. In addition, it is also widely used in marine engineering, shipbuilding industry and other fields.
In a word, as an advanced anti-corrosion technology, 3PE coated anti-corrosion spiral steel pipe has the characteristics of excellent anti-corrosion performance, good mechanical properties and stable electrical properties. At the same time, its advantages of environmental protection, safety and wide range of application make it occupy an important position in the anti-corrosion steel pipe market.
