Analysis of the applicable scenarios and characteristics of various color polyethylene-coated steel pipes
Plastic-coated composite pipes are classified as: hot-dip coating process, internal and external spraying process, rotational molding process, spray coating process, absorption coating process, fusion-bonded winding process, etc. The hot-dip coating adopts: fluidized bed coating and one-time film formation method.
Compared with other pipes, the greatest advantage of large-diameter plastic-coated pipes is that the pipe wall is smooth, with good drainage performance, low fluid resistance, no scaling, and can greatly reduce losses. At the same time, the linear expansion coefficient of large-diameter plastic-coated pipes is very small, which makes them very advantageous as main water pipes, greatly overcoming the disadvantages of other plastics and ordinary pipes with large linear expansion coefficients. Large-diameter plastic-coated pipes are high-performance upgraded products of traditional steel-plastic pipes and galvanized pipes.
Plastic-coated steel pipes are a type of anti-corrosion steel pipes with plastic layers coated on both the inner and outer surfaces. Their colors not only have an aesthetic effect but are also closely related to the usage scenarios and functional characteristics. The following is an analysis of the applicable scenarios and characteristics of various colors of plastic-coated steel pipes:
1. Green plastic-coated steel pipes
Applicable scenarios: Often used in water supply pipelines for drinking water, water supply and drainage systems, agricultural irrigation, etc.
Characteristics: Green represents environmental protection and complies with drinking water hygiene standards. They have good corrosion resistance and anti-aging properties and are suitable for humid environments. The inner wall is smooth, reducing water resistance and improving transportation efficiency.
2. Blue plastic-coated steel pipe
Application scenarios: Primarily used for fire protection pipelines, industrial water pipelines, cooling water systems, etc.
Characteristics: Blue symbolizes water, making it easy to identify and distinguish the purpose of the pipeline. It is resistant to high temperatures and high pressures, suitable for fire protection and industrial environments. It has strong resistance to chemical corrosion and is suitable for transporting corrosive media.
3. Red plastic-coated steel pipe
Application scenarios: Often used for fire protection pipelines, pipelines for transporting hazardous media, warning sign pipelines, etc.
Characteristics: Red has a warning effect, facilitating quick identification of dangerous areas. It is resistant to high temperatures and wear, suitable for high-pressure and high-temperature environments. It has strong impact resistance, suitable for complex working conditions.
4. Black plastic-coated steel pipe
Application scenarios: Primarily used for oil and gas transportation pipelines, buried pipelines, industrial pipelines, etc.
Characteristics: Black has the advantages of being dirt-resistant and having strong weather resistance, making it suitable for outdoor and buried use. It has excellent UV resistance and anti-aging properties, extending service life. It has strong corrosion resistance and is suitable for transporting oil and gas media.
5. Yellow plastic-coated steel pipe
Application scenarios: Primarily used for gas pipelines, chemical pipelines, warning sign pipelines, etc.
Characteristics: Yellow has a warning function, making it easy to identify dangerous medium transportation pipelines. It is resistant to corrosion and high temperature, suitable for gas and chemical scenarios. It has strong mechanical damage resistance, suitable for complex environments.
The color of the plastic-coated steel pipe is not only for aesthetics, but also for distinguishing the purpose, enhancing safety and functionality. Choosing the appropriate color and coating material can ensure that the pipe performs at its best in different scenarios, while meeting environmental protection, hygiene and safety requirements.
