Since the mid-1990s—when “five-layer pipe” was still new to Iran’s MEP market—Isopipe launched a reverse-engineering and R&D-driven production line that has grown into one of the most advanced extrusion facilities in the Middle East. This approach not only reduced reliance on imported European pipes and fittings, it also embedded local know-how in plastic-to-metal bonding across Iran’s pipe industry. Today, Isopipe’s third-generation machinery, equipped with German PLCs and continuous wall-thickness monitoring, holds dimensional tolerance under ±0.03 mm—a benchmark many international brands do not reach.
Five-Layer Pipe Structure Engineering
Isopipe PEX-AL-PEX and PERT-AL-PERT pipes consist of two dedicated polyethylene layers, a laser-welded aluminum core, and two adhesive resin layers. The Fusion Bond temperature is set at 245 °C to secure a stable organic–metal bond; as a result, the Peel Test passes without delamination even after 5,000 temperature/pressure cycles.
Technical Profile
| Outside Diameter (mm) | Aluminum Thickness (µm) | Working Pressure at 20 °C (bar) | Linear Expansion Coefficient (mm/m·K) |
|---|---|---|---|
| 16 | 200 | 10 | 0.025 |
| 20 | 230 | 10 | 0.026 |
| 25 | 250 | 10 | 0.026 |
| 32 | 350 | 10 | 0.027 |
Product Portfolio: From Pipe to Installation Tools
Isopipe offers 40+ active SKUs—from 16×2 mm coils up to 63 mm straight lengths—plus a complete range of nickel-chrome plated brass fittings. As a raw-material supplier, the company melts CuZn37 (63-37) brass ingots in induction furnaces and extrudes its own rods. This vertically integrated supply chain underpins consistent quality.
Fittings & Installation Methods
| Fitting Family | Required Tool | Avg. Install Time (s) | Part Recyclability |
|---|---|---|---|
| Press | Hydraulic press | 12 | Non-reversible |
| Coupling* | Single open-end wrench | 18 | Re-openable |
| Clamping* | Slip-joint wrench | 15 | Re-openable |
| Threaded | PTFE tape | 25 | Re-openable |
* Coupling and Clamping are proprietary Isopipe innovations. By removing press operations, they have become popular in apartment renovations where space and access to heavy tools are limited.
Key Advantages for Contractors & Owners
- Fast installation – Bend radius down to 5× OD cuts horizontal elbows by ≈30%.
- Material efficiency – Coupling fittings use ≈42% less brass than legacy threaded models, optimizing resource use.
- Chemical resistance & oxygen barrier – Oxygen ingress through the wall is < 0.1 mg/m²·day, crucial for preventing sludge in heating loops.
- Thermal durability – Designed lifetime of 50 years at 90 °C (per ISO 9080 curve) makes Isopipe reliable not only for DHW but also for industrial chilled-water service.
Standards & Certifications
- Iran National Standard Mark 6060, conforming to INSO 14427.
- ISO 9001:2015 and ISO 14001:2015 certified by TÜV Nord—aligned systems ensure uniform quality and minimal production waste.
- Health approval by the national Food & Drug Organization for continuous contact with potable water.
- ASTM F1281 and ISO 21003 for pipe and fittings; burst test at 95 °C / 11.5 bar / 1000 h showed no interlayer deformation.
- Housing & Urban Development Research Center approval authorizing use in risers of buildings above 25 floors (in Iran).
Applications
- Potable water networks and high-rise risers—thanks to excellent strength-to-weight ratio.
- Underfloor and radiator heating—aluminum layer blocks O₂ ingress, extending heat-exchanger and pump life.
- In-unit natural-gas piping—available with dedicated yellow marking and approvals where local codes permit (approved by the National Iranian Gas Company in Iran).
- Food & pharma utilities—DM water and clean compressed air, with Mirror-finish bore (Ra ≤ 0.007 mm).
- Neutral-fluid transfer in industrial plants—resistant to dilute acids down to pH 2 and weak bases up to pH 12.
Market Position (Iran)
While brands such as Superpipe, Newpipe, and BTS are active in Iran’s five-layer category, Isopipe’s press-free connection technology has captured a significant share of renovation projects in major cities over the past three years. Field data from the national MEP association indicate a 27% market share in 2024, ahead of the nearest competitor at 24%, largely due to easier installation of Coupling and Clamping fittings.
