Lined plastic steel pipe

Lined steel pipe is a composite pipe material formed by using galvanized seamless steel pipe or welded steel pipe as the base pipe, removing the welding ribs on the inner wall, and then lining it with food-grade polyethylene (PE) pipes or other thermoplastic pipes of the same diameter as the galvanized pipe. Finally, it is formed after being pressurized and heated for a certain period of time.

Reasons for misalignment of spiral steel pipes

Spiral steel pipes are prone to misalignment during production, and there are many influencing factors. In production practice, steel pipes are often downgraded due to dry edge deviation. Therefore, it is necessary to analyze the causes and preventive measures of misalignment in spiral steel pipes.

Maintenance methods for straight seam steel pipes

With the development of the economy, the country vigorously develops the energy industry, and long-distance oil and gas pipelines are an important way to ensure energy security. In the anti-corrosion construction process of oil and gas pipelines, surface treatment of straight seam steel pipes is one of the key factors determining the anti-corrosion service life of pipelines. It is a prerequisite for whether the anti-corrosion layer can be firmly combined with the steel pipe. After verification by research institutions, the lifespan of anti-corrosion coatings depends not only on factors such as coating type, coating quality, and construction environment, but also on the surface treatment of straight seam steel pipes, which accounts for about 50% of the lifespan of anti-corrosion coatings. Therefore, it is necessary to strictly follow the requirements of anti-corrosion coating specifications for steel pipe surfaces, continuously explore and summarize, and continuously improve the surface treatment methods of steel pipes.
