Cangzhou Hengtai Zeyuan Anti-corrosion Pipeline Co., Ltd.
1. Product Overview
Custom lined plastic pipes are advanced anti-corrosion pipelines that feature a strong metal outer layer (carbon steel or stainless steel) and a corrosion-resistant plastic inner lining. The inner lining materials typically include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polytetrafluoroethylene (PTFE). These pipes are designed for applications requiring specific dimensions, materials, and connection types to meet various industrial needs.
Custom lined plastic pipes combine the strength and pressure resistance of metal with the superior corrosion resistance of plastic, making them ideal for transporting aggressive chemicals, acids, alkalis, and other corrosive substances in industries such as chemical processing, pharmaceuticals, food production, and wastewater treatment.
2. Main Features
- Fully Customizable Design: Pipe diameter, length, lining material, and connection type can be tailored to project specifications.
- Exceptional Corrosion Resistance: Inner lining resists acids, alkalis, salts, and organic solvents, ensuring durability in harsh environments.
- High Mechanical Strength: The metal shell enhances structural integrity, making the pipe suitable for high-pressure applications.
- Smooth Inner Surface: Reduces fluid resistance, prevents scaling, and improves transport efficiency.
- Temperature and Pressure Adaptability: Different lining materials allow the pipe to withstand temperatures up to 200°C and pressures up to 2.5 MPa.
- Flexible Connection Options: Available in flange, welded, or threaded connections to meet installation requirements.
