Polyethylene pipes are known as one of the most widely used and widely used types of polymer pipes in the world. These pipes have found a special place in many industries, including agriculture, water and sewage, gas supply, the construction industry, and infrastructure projects, due to their high mechanical strength, long lifespan, economic price, and environmental friendliness.
What is polyethylene?
Polyethylene is one of the most widely used thermoplastics, produced from the polymerization of ethylene gas. Pipes made from this material fall into various categories, the most important of which are:
- PE32, PE40, PE63, PE80 and PE100 (based on strength and density).
- The most widely used type currently is PE100 polyethylene pipes, which have high resistance to pressure and cracking.
Features and benefits of polyethylene pipes
1-High resistance to corrosion and rust (unlike metal pipes).
2-Long service life (over 50 years under standard conditions).
3-Excellent flexibility → Ability to withstand stresses caused by earthquakes and soil subsidence.
4-Smooth and polished inner surface → Reduces pressure drop and increases fluid transfer efficiency.
5-Light weight → Easy to transport and install.
6-Reliable connections → Use of butt fusion and electrofusion welding, which creates a 100% seal.
7-High chemical resistance → Suitable for transporting chemicals and acids.
8-Economical savings compared to metal and many other materials.
Applications of polyethylene pipes
1-Agriculture and irrigation
- Use in drip and sprinkler irrigation systems.
- Transferring water from sources to fields and gardens.
- Drainage networks and surface water control.
2-Water and wastewater industry
- Transport of high quality drinking water without changes in taste and odor.
- Urban and industrial wastewater collection and transportation networks.
3-Gas supply
- Due to its high resistance to pressure and impermeability, it is widely used in urban and rural gas supply networks.
4-Industries and mines
- Transport of slurry, chemicals and industrial effluents.
- Used in mines for transporting abrasive and corrosive materials.
5-Building and infrastructure
- Used in construction projects, fire water transfer, cooling and heating systems.
- Used in telecommunications and electrical cabling as a protective sheath.
Quality standards and requirements
Polyethylene pipes must be manufactured according to international and national standards, including:
- ISO 4427 (for water transport).
- EN 12201 (for pressure systems).
- ISIRI 14427 (Iranian National Standard for Polyethylene Pipes).
Conclusion
Polyethylene pipes are recognized as an ideal and cost-effective option in many industries due to their unique properties. The right choice of raw material type, production standard, and installation method can extend the lifespan of these pipes to more than half a century.
Domestic manufacturing companies, including Polymer Pars, are also capable of supplying polyethylene pipes in various sizes and working pressures today and can meet the needs of small to large projects.
