Plastic coated steel pipes for water supply and drainage

Plastic-Coated Steel Pipes for Water Supply and Drainage

Product Overview:
Plastic-coated steel pipes are specially engineered for water supply and drainage systems, combining the strength of steel with the corrosion resistance and smooth surface of a plastic coating. These pipes provide a reliable, durable, and hygienic solution for transporting potable water, sewage, and other fluids in residential, commercial, and industrial applications.

Key Features:
The pipe consists of a high-quality steel core lined and/or coated with a layer of food-grade plastic—commonly polyethylene (PE), epoxy resin, or polyvinyl chloride (PVC). The inner plastic lining prevents scale buildup and bacterial growth, while the outer coating protects against external corrosion and mechanical damage.

Mechanical and Physical Properties:
The steel substrate provides high pressure resistance, impact strength, and dimensional stability. The plastic coating enhances chemical resistance and ensures a smooth internal surface, reducing flow resistance and improving hydraulic efficiency. These pipes are easy to install and compatible with a variety of connection methods, including welding, flanges, and threaded joints.

Applications:
Ideal for urban water supply and drainage networks, wastewater pipelines, fire protection systems, cooling water systems, irrigation, and chemical fluid transport. Suitable for both underground and aboveground installations in corrosive or humid environments.

Advantages:

• Excellent corrosion and chemical resistance

• Smooth inner wall for reduced friction and cleaner water flow

• Strong mechanical performance and long service life

• Safe and non-toxic materials for drinking water applications

• Resistant to soil pressure, wear, and impact

• Versatile installation options and low maintenance requirements

Quality Assurance:
All pipes undergo rigorous testing, including coating adhesion, thickness verification, hydraulic pressure testing, and health safety evaluation for potable water use. Products conform to national and international standards for water pipeline systems.
