Cangzhou Hengtai Zeyuan Anti-corrosion Pipeline Co., Ltd.
1. Product Overview
Lined plastic reducer pipe fittings are corrosion-resistant pipeline components used to connect pipes of different diameters. The exterior is made of carbon steel or stainless steel, while the interior is uniformly lined with anti-corrosion plastic materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polytetrafluoroethylene (PTFE). This product combines the high strength and pressure resistance of metal with the corrosion resistance of plastic lining, making it widely used in industries such as chemical processing, environmental protection, pharmaceuticals, and food production for transporting acids, alkalis, salts, and other corrosive media.
2. Main Features
- Excellent Corrosion Resistance: The inner lining effectively resists acids, alkalis, salts, and other corrosive substances, making it suitable for harsh environments.
- High Mechanical Strength: The carbon steel or stainless steel base provides sufficient strength and pressure resistance for high-demand applications.
- Smooth Inner Wall, Low Flow Resistance: The plastic-lined surface minimizes friction, improves transport efficiency, and reduces energy consumption.
- High and Low-Temperature Resistance: Different lining materials cater to various temperature requirements, with PTFE tolerating temperatures up to 200°C.
- Flexible Installation: Available in flange, welded, or threaded connections to suit various pipeline systems.
