Introduction
Plastic-lined pipes are steel-plastic composite pipes made with API 5CT series steel grades (J55, K55, T95, N80, C90, C95, and L80) as the core base material and lined with thermoplastic engineering plastics. Specifically engineered for industrial fluid conveyance where combined mechanical strength are needed.
Features
- Excellent Mechanical and Pressure Performance
It combines the excellent mechanical strength, pressure resistance, and impact resistance of API 5CT steel grades, having a long service life.
- Corrosion Resistance
The inner thermoplastic lining protects the steel from acid, alkali, and salt corrosion.
- Combined Material Advantages
The pipe combines an API 5CT steel base (J55–C95) with a thermoplastic lining (PE, PP, PO, PTFE), providing strong mechanical support, chemical stability, and reliable bonding.
Customization Options
- Base Material Selection
API 5CT series steel grades (J55, K55, T95, N80, C90, C95, L80).
-
Custom Size and Wall Thickness
Outer diameter, wall thickness, and pipe length can be customized to suit different pipeline system requirements.
- Lining Material Type
Thermoplastic options (e.g., PE, PP, PO, PTFE) for specific chemical resistance needs.
FAQ
Q: Is it suitable for high-pressure systems?
A: Yes, often higher pressure capacity than standard welded pipes.
Q: What is plastic-lined steel pipe used for?
A: 1. Water Supply & Treatment: Ideal for drinking water and treatment pipelines. Non-toxic linings (PE, PPR) prevent metal leaching, resist rust and scaling, and ensure smooth flow with low maintenance.
2. Chemical Industry: Suitable for transporting acids, alkalis, and solvents. PTFE or PP linings provide chemical stability, preventing corrosion and contamination in chemical plants, labs, and pharmaceutical facilities.
3. Food & Beverage Industry: Used for transporting milk, juice, beer, and other food products. Food-grade linings (PE, PPR) are non-toxic, odorless, easy to clean, and inhibit bacterial growth, ensuring food safety and quality.
4. Heating & Cooling Systems: Used in hot water pipelines and air conditioning cooling water pipelines. The heat-resistant inner lining (e.g., PPR) can withstand temperatures up to 95°C, while the metal base ensures good pressure-bearing capacity, suitable for residential buildings, commercial buildings, and industrial heating/cooling systems.
