Corrosion insulation performance of SSAW steel pipe

Anti-corrosion insulation pipes combine the corrosion resistance of steel with excellent insulation properties. They have been widely used and promoted in building construction, with continuous improvements and wider adoption. These pipes undergo various processing types and methods, each conferring different properties and functions, which expands their range of applications. As the name suggests, they enhance the corrosion and insulation protection of spiral steel pipes, allowing for use in low-temperature environments. This article will talk about the corrosion insulation performance of SSAW steel pipe.

Properties and Uses of Anti-Corrosion Insulation Pipes

Processing Methods

The type and method of processing determine the specific properties and functions of the insulation pipes, which in turn affect their applications. For example:

- Inorganic Zinc-Rich Paint: Typically used for second-degree pipe insulation, this paint can withstand temperatures of≥400°C and serves as a corrosion-resistant coating. The conduit port is often protected with polyethylene film (referred to as 3-layer PE) or cold sealing tapes to prevent moisture ingress during installation.

Applications

Anti-corrosion insulation pipes are suitable for high-temperature environments, water and fuel pumps, and chemical pumps. The insulation materials used in these pipes are designed to reduce heat loss effectively and control the jacket surface to prevent the formation of cold bridges. This ensures that the outer coating maintains a controlled temperature.

- Multilayer Bandaging: Insulation materials are applied in multilayer bands with offset seams, effectively reducing heat loss and controlling the jacket surface to prevent cold bridges.

- Reflective Aluminum Foil:Wrapping the spiral steel pipe with insulation material and a multilayer reflective layer of aluminum foil significantly reduces heat loss, making steam pipes more economical and efficient.

Benefits

The anti-corrosion insulation properties of SSAW steel pipes provide several benefits:

- Corrosion Resistance:These pipes offer excellent resistance to corrosion, making them suitable for harsh environments.

- Insulation Performance:They possess superior insulation properties, reducing energy loss and improving efficiency.

- Wide Application Range:With various processing methods, these pipes can be tailored for different uses, from high-temperature industrial applications to construction and design projects.
