Anti-corrosion steel pipe refers to the anti-corrosion treatment of ordinary steel pipes by coating, spraying or covering to improve its corrosion resistance in harsh environments. Anti-corrosion steel pipes are widely used in petroleum, chemical industry, electric power, water conservancy, urban construction and other fields.
This article will introduce in detail the types, characteristics, applications, etc. of anti-corrosion steel pipes.
Types of anti-corrosion steel pipes
The more common types of anti-corrosion steel pipes currently on the market include the following:
3PE anti-corrosion steel pipe: Coated with three layers of PE material, the inner part is an epoxy powder anti-corrosion layer, the middle is an adhesive layer, and the outer surface is made of polyethylene material (i.e., leather casing). This structure not only ensures the anti-corrosion effect, but also provides external protection.
IPN8710 anti-corrosion steel pipe: It has a high anti-corrosion level and uses an anti-corrosion layer composed of epoxy resin, pigments, solvents and other materials. It has a high level of hygiene and is therefore widely used in conveying pipelines for food and drinking water.
Epoxy powder anti-corrosion steel pipe: It is a new type of anti-corrosion layer that is coated by dissolving epoxy powder and applying it to the surface of the steel pipe. This anti-corrosion layer structure has excellent anti-corrosion effect and is widely used in pipeline systems that transport water over long distances.
Characteristics of anti-corrosion steel pipes
1. Strong chemical corrosion resistance: Using high-quality epoxy resin, polyurethane and other materials as the internal anti-corrosion layer, it can operate stably in harsh media such as acid, alkali, salt and so on.
2. Good wear resistance: Since the external anti-corrosion layer is usually made of polymer materials, it has good wear resistance and scratch resistance, and can effectively protect the surface of the steel pipe from damage.
3. Good aging resistance: the internal and external anti-corrosion layers have a long service life and can meet the needs of various fields.
4. Easy installation and maintenance: Anti-corrosion steel pipes are easy to install, and the maintenance workload after use is also small, reducing maintenance costs and usage risks.
Application of anti-corrosion steel pipes
1. Oil, natural gas and other industries: Anti-corrosion steel pipes are widely used in pipeline systems for transporting liquid and gaseous media such as oil and natural gas. Their excellent corrosion resistance and reliable sealing performance protect oil and gas transportation.
2. Chemical industry: In the chemical production process, it involves the transportation and storage of many harmful chemicals. The use of anti-corrosion steel pipes can effectively avoid safety issues such as pipeline erosion and material leakage.
3. Electric power industry: Anti-corrosion steel pipes are used to transport gas, water and steam, as well as cooling pipes, heaters and boiler pipes and other equipment to ensure the safe and efficient operation of the power system.
4. Municipal construction: Anti-corrosion steel pipes are widely used in municipal construction fields, such as water supply, drainage, oil and gas transmission and other pipeline systems. Its anti-corrosion performance can ensure that the pipeline system is not corroded for a long time, reducing maintenance work and safety hazards.
5. Mining, metallurgy and other industries: In mining, metallurgy and other industries, anti-corrosion steel pipes are used to transport various solid and liquid media, such as pulverized coal, ash, wastewater and other materials, ensuring the stability and safety of transportation equipment.
In short, anti-corrosion steel pipes have a wide range of applications and excellent corrosion resistance. With the continuous advancement of science and technology and the continuous expansion of the market, anti-corrosion steel pipes will better meet the needs of various industries for pipeline systems and provide more reliable support for people's production and life.
