Easy Handling and Installation
- Plastic pipes are generally lighter than other materials which means they are easier to handle and install
- For usual sizes of buried pipes for drainage or sewage, it requires only one person to handle, put in position and achieve jointing. Mechanical lifting is only necessary for the larger diameter pipes
- Plastic pipes also incur lower transport, handling and manpower costs
- Buried plastic pipes can cope better with ground movement, loadings and stresses. Compared with alternative rigid materials, they are less at risk of cracking, collapse or consequential leakage
- The flexibility of plastic pipes means they can often be channelled around angles and obstructions without requiring extra jointing and fittings. Some types and sizes are typically supplied in coils and that is a great bonus when it comes to space!
- Plastic pipes used in water mains, sewer and gas distribution applications can be deflected without loss of integrity to follow the curved alignment of streets or other necessary small changes of direction
- Plastics are non-conductive and are therefore immune to galvanic or electrolytic erosion. They can be safely buried in acidic, alkaline, wet or dry soils. Protective coatings are not required
- Plastic piping materials have good resistance to most common chemicals. Certain types can even successfully handle industrial chemicals
- Plastic pipes are not subject to biological attack from fungi, bacteria, or insects
Low Friction and Maintenance
- Their material toughness and smooth inner bore provide excellent resistance to abrasive materials which they may transport
- This smooth bore means less power required to move liquids through the pipeline
- In gravity systems, good flow characteristics are assured. And for pipes that are laid to a gradient, a self-cleansing velocity is easier to achieve
- If properly installed, plastic pipes require very little maintenance because in normal use, they do not rust, pit or scale
- Their smooth non-porous bore means that debris and detritus cannot easily adhere to the inner surfaces. Stubborn blockages are less likely
- Commonly used are black or grey pipes and fittings for rainwater sewer systems and red-brown pipes and fittings for waste water systems.
- Plastic pipes can also be produced in all kinds of colours to assist identification for specific applications.
Plastic pipes systems offer an energy efficient piping solution, mainly due to their low weight. Rising energy prices and growing awareness of the need to reduce greenhouse gas emissions are making energy-efficiency a key parameter especially when politicians, companies, organisations and people make decisions for the future. The plastic pipe industry has responded positively to these challenges.
