Composite Pipe FAQ
What are the main advantages of composite pipes over traditional metal pipes?
Composite pipes offer several significant advantages: They are corrosion-resistant, eliminating the need for protective coatings or cathodic protection required for steel pipes. Their lightweight nature reduces transportation and installation costs. They have superior hydraulic characteristics with smoother interior surfaces that maintain flow efficiency over time. Composite pipes also demonstrate excellent fatigue resistance and don't suffer from galvanic corrosion when in contact with other metals.
What industries commonly use composite pipes?
Composite pipes are widely used across multiple industries including: Oil and gas (for produced water, injection lines), Chemical processing (for corrosive fluid transport), Water treatment (for desalination plants), Power generation (for cooling water systems), Mining (for slurry transport), and Marine applications (for seawater systems). Their corrosion resistance makes them particularly valuable in harsh environments where traditional materials fail prematurely.
How do composite pipes perform in extreme temperatures?
Our composite pipes are engineered to perform in a wide temperature range from -40°C to 120°C continuously, with short-term peak resistance up to 150°C. The thermal expansion coefficient is significantly lower than plastics (about 1/3 that of HDPE) and similar to carbon steel, making them suitable for applications with temperature fluctuations. Special high-temperature resin systems can be specified for applications requiring continuous service above standard temperature ranges.
Installation Guidelines
- Prepare trench with proper bedding material (typically 150mm granular bedding)
- Use proper lifting techniques (nylon slings recommended)
- Follow manufacturer's jointing procedures carefully
- Maintain proper alignment during installation
- Conduct pressure testing according to project specifications
- Complete proper backfilling in layers with appropriate compaction
Pressure Rating Table by Diameter
| Nominal Diameter (mm) | Standard Pressure Rating (bar) | Maximum Pressure (bar) |
|---|---|---|
| 50 | 25 | 37.5 |
| 100 | 20 | 30 |
| 200 | 16 | 24 |
| 400 | 10 | 15 |
| 600 | 8 | 12 |
Maintenance Requirements
Composite pipes require minimal maintenance compared to traditional piping materials. Routine inspection should focus on: checking for mechanical damage, verifying support conditions, and monitoring any unusual vibrations. Internal inspection may be needed in slurry applications to check for erosion patterns. The expected service life exceeds 25 years with proper installation and operation within design parameters.
