Tehran Etesalat — Four Decades of Polymer Pipe & Fittings Expertise
With more than 40 years of continuous manufacturing, Tehran Etesalat is a trusted name for MEP engineers and infrastructure contractors. Since 1979, when it launched Iran’s first U-PVC extrusion lines, the company has led the localization of rigid-plastic technologies. In the 1980s, capacity doubled with European equipment and an independent quality-control lab was established. Today the lab features 16-bar hydrostatic testing, thermal-shock autoclave, and an accelerated weathering chamber—enabling continuous product monitoring. Proven performance in nationwide sewer networks, national housing programs, and mechanized farms has made Tehran Etesalat a staple brand in contractors’ procurement lists.
Manufacturing Backbone & Quality Assurance
The plant sits on 40,000 m² in Shamsabad Industrial Town, operating 18 pipe-extrusion lines and 24 injection-molding machines to fulfill large orders on short lead times. All lines use PLC controllers with continuous temperature–pressure monitoring for consistent production. PVC K-67 compound is sourced from reputable local and international suppliers, while in-process checks of Ca/Zn stabilizer, lubricants, and titanium dioxide preserve long-term color stability and impact resistance. In addition to Iranian National Standards 9119 (pipes) and 12142 (fittings), Tehran Etesalat holds ISO 9001 and ISO 14001 certifications and runs an integrated quality-management system.

| Product Group | Nominal Diameter (mm) | Working Pressure (bar) | Joint Type | Key Application |
|---|---|---|---|---|
| U-PVC Building Pipe | 63–110 | 4, 6 | Solvent-weld | Indoor wastewater, vent stacks |
| U-PVC Pressure Pipe | 90–200 | 10, 16 | Solvent-weld / O-ring | Potable water transfer, irrigation |
| 45° & 90° Elbows | 63–200 | Per matching pipe | Solvent-weld / O-ring | Direction changes |
| Tees & Crosses | 63–200 | Per matching pipe | Solvent-weld / O-ring | Branch connections |
| Couplers, End Caps, Traps | 63–160 | 4, 6, 10 | Solvent-weld / O-ring | Joining, end sealing, water trap |
Application Scope & Technical Advantages
- Buildings: Low weight, no threading, and chemical resistance to common cleaners make it the default choice for indoor drainage.
- Urban Infrastructure: Smooth U-PVC walls reduce head loss and resist sedimentation in gravity sewers.
- Agriculture & Irrigation: 10 and 16-bar ratings at ≥160 mm diameters support long-distance pumped lines.
- Industry: Resistance to dilute acids, bases, and salts ensures safe transfer of process solutions.

| Evaluation Factor | Tehran Etesalat U-PVC | Galvanized Steel Pipe | PE100 Pipe |
|---|---|---|---|
| Corrosion Resistance | Very high | Low | Very high |
| Internal Roughness (mm) | 0.007 | 0.15 | 0.008 |
| Service Life (years) | >50 | 20–30 | 50 |
| Density (g/cm³) | 1.4 | 7.8 | 0.95 |
| Installation Effort | Low | High | Medium |
Competitive Advantages
- Dimensional Stability: Heat-stabilized formulation limits linear change to <2.5% from −20 to +60 °C.
- Leak-Tight Joints: EPDM O-rings (65 Shore A) ensure zero leakage up to 16 bar in a 1,000-hour test.
- Full Fittings Portfolio: 250+ SKUs—single-source supply for complete project packages.
- Wide Logistics Coverage: Regional warehouses in Tabriz, Mashhad, and Shiraz enable 48-hour delivery across Iran.
- Technical Support: Sales engineering team provides sizing and hydraulic software to optimize line layouts.
