Mahan Plast Tabriz — Raising the Bar in Iran’s Polymer Pipe Industry
Over the past two decades, Iran’s polymer pipe & fittings sector has grown rapidly. Among its driving forces stands Mahan Plast Tabriz—not only for high production capacity, but for engineering discipline and continuous innovation that have helped lift national quality standards. Ideation began in 2010 and industrial production launched in 2011 at the Tabriz Industrial Park. Today, fully automated extrusion lines and a reference laboratory—equipped for OIT (Oxidation Induction Time), DSC (Differential Scanning Calorimetry), MFI (Melt Flow Index) and long-term hydrostatic testing—enable reliable delivery for large national infrastructure projects. Every coil or straight length leaves the plant only after at least 9 quality-control stages and issuance of a Certificate of Conformity (CoC), ensuring thermal stability, resistance to environmental stress, and uniform wall thickness.
Product Range & Applications
Mahan Plast operates across three major families—PE, U-PVC, PP—with specialized sub-ranges for municipal water transmission (up to PN16), low-pressure drip irrigation, and color-coded gas distribution pipes. For wastewater, the portfolio includes socketed U-PVC soil & waste systems and low-noise PP push-fit systems with sound insulation classes compliant with DIN 4109. For buildings, PP-RCT/PP-R fusion pipes serve domestic hot water, with modified crystalline structure for sustained service up to 95 °C.

| U-PVC Soil & Waste Pipe | 50–315 | 4 | U-PVC | Building drainage | ISIRI 9119 |
| PP Silent Push-Fit | 40–160 | 4 | Mineral-reinforced PP | Low-noise drainage in high-rises | DIN EN 1451 |
| PP-R Hot Water Pipe | 20–110 | 20 | PP-RCT | Potable hot water & heating | ISIRI 11215 |
Manufacturing Technology & Continuous Innovation
Working closely with Sahand University of Technology (Tabriz), Mahan Plast has localized multi-antioxidant formulations (HALS, AO-1010) to extend service life in hot southern climates. Next-generation extruders with gravimetric blenders and online ultrasonic gauges hold wall-thickness within ±0.1 mm. This precision reduces material waste and extends system life; FEA on PE100 samples shows burst pressure up to 27% above INSO minimums.
Quality Assurance & Certifications
Beyond full compliance with Iran National Standards across sizes, the company is certified to ISO 9001:2015 (QMS), ISO 14001:2018 (EMS) and ISO 45001:2018 (OHS)—a framework that tracks product life-cycle from resin sourcing to scrap recycling. QR-code traceability on every pipe length or coil provides project supervisors with real-time access to hydrostatic test records.

| Heat-fusion Joint Defect Rate (%) | <1 | 3–5 | 7–10 |
| Hydro Test 16 bar / 1000 h | Pass | Some fail | Often not tested |
| Written Warranty | 10-year replacement | 2–5 years | None |
| CaCO₃ in U-PVC (%) | ≤5 | 8–12 | 15–20 |
| Active Dealers | 180+ | 50–70 | Limited to importer |
Distribution Network & Technical Services
With 180+ active dealers from Urmia to Bandar Abbas, deliveries reach project sites within 72 hours nationwide. Mobile technical teams—equipped for butt fusion and electrofusion up to Ø315 mm—support on-site installation, a critical advantage for rural water and large farm networks. Pre-sale support continues with installer training courses and official certificates to minimize installation errors.
Environmental & Social Responsibility
An in-house recycling line converts production scrap into second-grade pellets for double-wall drainage pipes, cutting virgin resin consumption by ~9% annually. Through the “Water for All” initiative, a portion of rural water-supply sales supports access to safe drinking water—benefiting 23 villages to date.
Flagship Projects
- Khoda-Afarin Dam Trunk Line: 110 km of PE100, Ø400 mm
- Tabriz National Housing Wastewater Network: 98,000 m of PP Silent push-fit
- Moghan Plain Pressurized Irrigation: 35,000 ha under irrigation
- Boukan Gas Network Rehabilitation: PE100 electrofusion system, Ø160 mm
Growth Roadmap
Phase-III expansion adds two Ø635 mm extrusion lines and a 1,200-ton injection unit for large-diameter fittings. Servo-drive robots shorten molding cycle times by up to 18%. In R&D, glass-composite core multilayer pipes are under study to reduce axial thermal expansion.
How to Source
As an authorized seller, Tamam Baha can supply the complete Mahan Plast portfolio to developers, greenhouse operators and MEP/wholesale outlets nationwide, along with technical coordination to ensure access to genuine products.
