The importance and advantages of anti-corrosion for spiral welded pipes

Anti-corrosion steel pipes play important and different roles in people's daily lives. Anti-corrosion steel pipes generally refer to the use of special processes to perform anti-corrosion treatment on ordinary steel pipes, so that the steel pipes have a certain anti-corrosion ability. They are generally used for waterproofing, Anti-rust, anti-acid and alkali, anti-oxidation and other properties. Generally speaking, PE anti-corrosion steel pipe refers to polyethylene anti-corrosion steel pipe, which is a tubular item processed using advanced science and technology. PE anti-corrosion steel pipe is widely used in petroleum, Natural gas, city gas, urban water supply, coal water slurry transmission pipelines, etc.

Corresponding anti-corrosion measures can be taken for the inner and outer walls of spiral welded pipes according to different needs. The common ones include epoxy coal pitch anti-corrosion steel pipes, polyurethane coating anti-corrosion, anti-corrosion steel pipe inner wall cement mortar anti-corrosion, etc. Anti-corrosion spiral welded steel pipes are mainly used in Engineering fields with special requirements or harsh environments.

Spiral welded pipes are processed with anti-corrosion technology, which can effectively prevent or slow down the corrosion of steel pipes caused by chemical or electrochemical reactions during transportation and use. According to my country's statistics, the annual direct economic loss of domestic steel pipe corrosion is more than 280 billion US dollars. Currently, the global annual loss due to steel pipe corrosion is as high as 500 billion US dollars. Anti-corrosion steel pipes can effectively prevent or slow down corrosion, extend the service life of steel pipes, and reduce steel pipe operating costs.

Features of spiral welded pipe for anti-corrosion:
Corrosion-resistant, non-leakage, high toughness, excellent flexibility, good resistance to scratches, and good resistance to rapid crack transmission. The anti-corrosion spiral steel pipe has a long service life and can be used in an environment of greater than or equal to 60 degrees Celsius. It can have a life span of more than 50 years.

In addition to improving the service life of the steel pipe through anti-corrosion, the spiral welded steel pipe is also reflected in the following aspects:
1. Combine the mechanical strength of steel pipes and the corrosion resistance of plastics.
2. The outer wall coating is more than 2.5mm, resistant to scratches and bumps.
3. The friction coefficient of the inner wall is small, 0.0081-0.091, which reduces energy consumption.
4. The inner wall is smooth and not easy to scale, and has a self-cleaning function.
