Poliran has focused on developing fluid-transfer systems for buildings and agriculture since 1973, providing a reliable backbone for a wide range of national projects. By implementing ISO 9001:2015 and working with accredited laboratories, the company manages a closed loop of research, design, manufacturing, and quality control—earning multiple technical approvals and industrial design awards across the Middle East.
Production Range: From PEX to Silent Push-Fit
Smart Poliran factories supply thermoplastic parts across three core clusters:
- Building drainage systems — standard push-fit, Silent push-fit, and Protect self-extinguishing.
- Pressurized water and irrigation networks — polyethylene pipes and fittings, threaded and fusion fittings.
- Drip & micro-irrigation — emitters, lateral lines, and UV-stabilized risers.
Multi-stage injection molding, electrofusion welding, and two-stage extrusion deliver breadth of range with consistent mechanical properties.
Competitive Advantages at a Glance
| Product Category | Signature Feature | Key Applications | Edge over Competitors |
|---|---|---|---|
| Silent Push-Fit | Up to 97% noise attenuation | Residential towers, hospitals | High-density mineral–polymer multilayer |
| Protect Push-Fit | Self-extinguishing (UL 94 V-0) | Data centers, high-rise hotels | DIN 4102 B1 classification |
| PE100 Polyethylene | Working pressure 25 bar | Water & gas transmission lines | Stress-crack resistance (FNCT) > 100 h |
| Drip Fittings | High UV resistance | Orchards & landscaping | Proprietary antioxidant formulation |
Inside the Push-Fit Technology
Poliran push-fit joints use a triple-lip EPDM O-ring for a durable, adhesive-free, heat-free seal. The Silent version pairs a mineral-filled inner layer with a PP-copolymer outer shell to bring flow noise down to building background levels. In an 850 °C glow-wire/flame test, the Protect model self-extinguishes in about 3 seconds—critical for vertical utility shafts in high-rise buildings.
Polyethylene Pipes: DIN 8074—Updated
Laser wall-thickness scanners on Poliran’s extrusion lines keep dimensional stability across 20–1200 mm diameters. Full chemical resistance at pH 2–12, flexibility down to −30 °C, and a 50-year design life at PN16 make these pipes ideal for rural water grids and industrial effluent lines.
The Future of Irrigation Systems
Poliran drip fittings, engineered for uniform flow, have recorded a Clogging Index (CI) < 4%, improving water efficiency by up to 30% in leafy-vegetable farms. HALS-stabilized engineering polymers preserve color and mechanical properties after 10,000 hours of equivalent sunlight.
Polymer vs. Metal Pipe—Property Comparison
| Criterion | PE100 | Galvanized Steel |
|---|---|---|
| Density (g/cm³) | 0.96 | 7.85 |
| Thermal conductivity (W/m·K) | 0.42 | 40–55 |
| Fatigue life (cycles) | > 10⁷ | ~ 10⁴ |
| Electrochemical corrosion | None | Present |
| Relative weight | 1× | 8× |
Environmental Responsibility
Through process-scrap recovery and a “zero-effluent” program at Mahmoudabad Industrial Park, Poliran diverts 3,000+ tons of plastic annually from landfill and incineration. All packaging uses recyclable polymers and water-based inks.
