Photocuring anti-corrosion steel pipe is a new type of anti-corrosion pipe using ultraviolet light (UV) curing technology. With its efficient and environmental protection characteristics, it has been rapidly promoted in petroleum, chemical, municipal and other fields. Light curing anti-corrosion steel pipe is coated with special photosensitive resin material on the inner wall of the steel pipe, which can quickly solidify in a few minutes after high intensity ultra-violet light irradiation, forming dense and high strength anti-corrosion coating, completely changing the disadvantages of traditional time-consuming and large pollution of anti-corrosion technology.
Photocuring anticorrosion steel pipes have the following significant advantages:
Revolutionary improvement of construction efficiency: Traditional anti-corrosion needs several hours of curing, while light-curing anti-corrosion steel pipe only takes 3-5 minutes to complete, and the construction efficiency is improved by tens of times.
Super anti-corrosion performance: The cured coating has excellent corrosion resistance, can resist the erosion of strong acid, strong alkali, salt spray and organic solvents, and the service life of more than 20 years.
Green environmental protection: No VOCs emission in the whole process, and the coating materials meet the food grade standards, especially suitable for drinking water transmission pipeline.
Intelligent construction: Robot automatic coating can be used to ensure uniform coating thickness and stable and reliable quality.
At present, light cured anti-corrosion steel pipe has been successfully used in oil field water injection pipeline, chemical industry park pipe network, urban old pipeline repair and other key projects. Compared with traditional FBE, liquid epoxy and other anti-corrosion processes, light-cured anti-corrosion steel pipe shows irreplaceable advantages in emergency repair, narrow space operation and other scenes, and is known as "a revolution of anti-corrosion technology". With the continuous upgrading of UV curing materials, light-curing anti-corrosion steel pipes are being applied to more complex working conditions such as deep-sea pipelines and high-temperature medium transportation.
Compared to traditional anti-corrosion processes, photocuring anti-corrosion steel pipe has gained recognition from users for its high efficiency, environmental friendliness, and high performance. It features ultra-fast curing, with a curing time of approximately 30 seconds to 5 minutes at room temperature. Cutting, transporting, and installation can be performed immediately after curing, making it a fast process.
Environmentally friendly: Solvent-free or low-VOC coatings eliminate toxic emissions during the entire production process. These environmentally friendly features protect workers and the environment.
Coating performance: Adhesion ≥ 6 MPa, corrosion resistance: No red rust after 2000 hours of salt spray testing, excellent flexibility, and crack-free performance after a 180° bend test.
Economical and efficient: High cost-effectiveness, a key concern for users, is achieved with photocuring anti-corrosion steel pipes. High-temperature curing is not required, and the application period is short, reducing labor and site rental costs.
Versatile: The entire application process can be performed at room temperature, making it suitable for on-site repairs or large-diameter pipes.
As users, we're particularly concerned about the service life of photocuring anti-corrosion steel pipes. Under normal circumstances, they can last up to 50 years. This is because the cured coating forms a dense protective layer that provides excellent corrosion resistance. Even in extreme environments, the service life can exceed 7 to 8 years.
In addition, the following factors affect the service life of photocuring anti-corrosion steel pipes:
Coating Material: Epoxy or polyurethane-based UV coatings, temperature resistant from -30°C to 120°C, with excellent resistance to UV aging;
Application Process: Automated spray coating + UV curing ensures flawless adhesion, with adhesion ≥ 4B;
Environmental Conditions: Long-term exposure to strong acids or mechanical shock can shorten service life.
