Flange-connected spiral steel pipe is obtained by welding a piece of flange at both ends of the spiral steel pipe. It has the characteristics of convenient connection and easy installation, which saves time for a relatively special working environment, and its performance is stable, so it is quite useful. Many. However, compared with ordinary welding methods, its price is higher.
Flanged spiral steel pipes are generally used for water supply and drainage projects, and are generally used for exposed pipes. Therefore, anti-corrosion treatment is required. Now, the more anti-corrosion methods used are glass fiber reinforced plastics, polyurethane anti-corrosion and plastic coating anti-corrosion. Among them, plastic coating and anti-corrosion are the anti-corrosion methods that have developed rapidly in recent years.
The flanged spiral steel pipe can be any length between 1-12m, but 12m and 6m are used more, and the pressure level is not higher than 25kg.
