What are the application scenarios of the Kungwang steel belt polyethylene composite pipe?

The Kungwang steel-bonded polyethylene composite pipe combines the high strength and high pressure resistance of steel pipes with the corrosion resistance and environmental friendliness of polyethylene pipes. Its application spans across multiple fields such as municipal engineering, building water supply and drainage, gas transmission, and industrial fluid transportation.

Municipal water supply and drainage project

Urban Water Supply Pipeline Network: Suitable for main, secondary, and residential pipeline networks, this water supply pipeline is especially designed for underground installation, capable of withstanding soil pressure and ground loads. Its smooth inner wall prevents scaling and minimizes head loss, ensuring long-term water transportation efficiency. It is compatible with medium and high-pressure water supply scenarios up to PN1.0~2.0MPa.

Rainwater and Sewage Separation Pipeline: Designed for urban rainwater collection and sewage discharge, with a ring stiffness of ≥8kN/m², it can withstand deformation under complex underground conditions. Additionally, the PE layer is resistant to the corrosive effects of acidic and alkaline media in sewage, preventing pipeline aging and leakage.

2. Gas Transmission Field

Gas-specific piping materials compliant with CJ/T182-2003 standards are suitable for urban medium and low-pressure gas buried pipelines. They operate within a temperature range of -15℃ to 40℃. The PE layer features anti-static and corrosion-resistant properties, while the steel strip frame ensures the pipeline's ability to withstand external pressure, reducing the risk of gas leaks. They are commonly used for residential gas distribution branches and secondary municipal gas pipelines.

Building Drainage and Water Supply Systems

High-rise Building Standpipe: Suitable for water supply standpipes in high-rise residential and commercial buildings, it boasts high pressure resistance (PN 1.6~2.5MPa) to meet the water pressure demands of high-rise structures. The lightweight nature of the piping material ensures easy installation, and compared to steel pipes, it can reduce construction costs.

Building Fire Protection External Network: Certain specifications are suitable for outdoor fire piping in buildings, offering corrosion resistance while meeting pressure and impact resistance requirements, thereby reducing the frequency of post-maintenance.

4. Industrial Fluid Transportation

For corrosive or neutral fluid transportation in industries such as chemicals, metallurgy, and mining, such as dilute acids, alkali solutions, and pulp wastewater, the PE layer can withstand medium erosion with pH values ranging from 1 to 13. The steel strip frame ensures the structural stability of the pipeline under heavy load environments in industrial parks, and meets the HG/T3706-2014 standard for industrial pipe materials.

5. Special Engineering Scenarios

Urban Utility Tunnel: Suitable for integration into comprehensive utility tunnels, its composite structure combines flexibility and strength, adapting to the space constraints within the tunnel and minor displacement during post-maintenance operations, without the risk of electrochemical corrosion.

Suspension Pipelines: Suitable for overhead water supply or process pipelines in industrial or park areas, these pipelines are secured by matching brackets, eliminating the need for frequent anti-rust maintenance compared to steel pipes, thereby reducing long-term operation and maintenance costs.

Agricultural irrigation and water conservancy projects: Suitable as trunk water conveyance pipelines in large-scale agricultural irrigation systems, they can withstand outdoor temperature variations and soil erosion. Additionally, their high-pressure resistance ensures pressure requirements for long-distance water transportation. They can also be used as branch pipelines for water intake and discharge in small-scale hydraulic power stations.
