What are the connections and applications of spiral anti-corrosion steel pipes

First, what is a spiral anti-corrosion steel pipe?

In the field of pipeline engineering systems, steel pipe corrosion is a very serious and challenging issue. To solve this problem, a rather remarkable product has emerged on the market—spiral anti-corrosion steel pipe. As the name suggests, spiral anti-corrosion steel pipe is made by coating spiral steel pipes with an anti-corrosion material on both its inner and outer walls. This composite steel pipe not only inherits the mechanical properties of spiral steel pipes but also possesses the corrosion resistance unique to anti-corrosion coatings.

Second, what are the connection methods for spiral anti-corrosion steel pipes?

1. Welding connection of spiral anti-corrosion steel pipes: Welding connection is one of the most common connection methods for spiral anti-corrosion steel pipes. Welding connections can be divided into manual welding and automatic welding. Manual welding is suitable for small-diameter pipes, while automatic welding is suitable for large-diameter steel pipes. Before welding, the steel pipe needs to be cleaned and derusted to ensure welding quality. 1. Welding: Appropriate welding methods and materials must be selected based on the material and specifications of the steel pipe to ensure weld strength and sealing.

2. Flanged Connection of Spiral Anti-corrosion Steel Pipes: Flange connection is a common pipe connection method, suitable for both pipe connections and branches. Flange connections include various types such as slip-on flanges, butt-welded flanges, threaded flanges, and blind flanges. When using flange connections, appropriate flange models and gaskets must be selected to ensure the sealing and stability of the connection.

3. Clamp Connection of Spiral Anti-corrosion Steel Pipes: Clamp connection is a simple, convenient, and quick pipe connection method, suitable for small-diameter pipes and temporary pipelines. Clamp connections are divided into single-clamp and double-clamp types, with double-clamp connections offering better sealing and stability. When using clamp connections, appropriate clamp models and gaskets must be selected to ensure the sealing and stability of the connection.

When using clamp connections, appropriate clamp models and gaskets must be selected to ensure the sealing and stability of the connection. 4. Socket Connection of Spiral Anti-corrosion Steel Pipes: Socket connection is a common pipe connection method, suitable for large-diameter and high-pressure pipelines. Socket connections are divided into two types: rubber socket connections and metal socket connections. Rubber socket connections offer better sealing and corrosion resistance. When using socket connections, it is necessary to select the appropriate socket type and sealing gasket to ensure the sealing and stability of the connection.

There are various connection methods for spiral anti-corrosion steel pipes. The appropriate connection method and materials must be selected based on the pipe material, specifications, and operating environment to ensure the strength, sealing, and stability of the connection. During use, regular inspection and maintenance of the pipeline connections are also necessary to ensure the safe operation of the pipeline.

Third, what is the Application Scope of Spiral Anti-corrosion Steel Pipes?

Spiral anti-corrosion steel pipes have a wide range of applications, mainly used for the external corrosion protection of buried or underwater steel oil, gas, water supply, and heating pipelines. They are also suitable for corrosion protection of various steel structures, docks, ships, sluice gates, gas storage tanks, and equipment in oil refineries and chemical plants. In concrete structures, anti-corrosion spiral steel pipes also play an important role, and can be used for waterproofing and seepage prevention projects, such as the construction of sewage tanks, roof waterproofing layers, bathrooms, basements, and other parts.
