Cangzhou Hengtai Zeyuan Anti-corrosion Pipeline Co., Ltd.
1. Product Overview
A lined plastic elbow is a new type of anti-corrosion pipeline fitting. It consists of a carbon steel or stainless steel base with an inner lining of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polytetrafluoroethylene (PTFE). This product combines the high strength of metal with the corrosion resistance of plastic lining, making it widely used in industries such as chemical, environmental protection, pharmaceuticals, and food processing. It is particularly suitable for transporting highly corrosive media such as acids, alkalis, and salts.
2. Main Features
- Excellent Corrosion Resistance: Resistant to acids, alkalis, salts, and other corrosive media, extending pipeline service life.
- High Strength and Pressure Resistance: The carbon steel base provides strong mechanical support and impact resistance, suitable for various working conditions.
- Smooth Inner Wall, Anti-Scaling: Reduces fluid resistance, improves transport efficiency, and lowers maintenance costs.
- High and Low-Temperature Resistance: Different lining materials meet various temperature requirements, with PTFE tolerating temperatures up to 200°C.
- Flexible Installation: Available with flange, welded, or threaded connections to suit different engineering needs.
