Since the 1980s, Kaveh Gostar has grown into a key Iranian manufacturer of polyethylene piping systems. Our portfolio covers the full fluid-transfer chain—from trunk water lines and irrigation to wastewater collection and drainage—backed by modern R&D and process control.
Innovation in Materials & Manufacturing
- Next-gen PE compounds (PE100RC, PE100+) for long-term stress durability and high resistance to slow crack growth (SCG) and point loading.
- Multi-stage extrusion for uniform wall thickness and tight dimensional tolerances.
- Smart in-line monitoring: sensors log wall thickness, melt temperature, and cooling rate every second against reference ranges.
- Environmental responsibility: 100% in-house scrap recycling, LED lighting, and closed-loop water cooling to cut carbon footprint.
Certifications & Standards
- ISO 9001:2015 — Quality Management System (consistent product conformity to project specs).
- ISO 45001:2018 — Occupational Health & Safety (reduced site risk).
- ISO 14001:2015 — Environmental Management (lower waste and energy use).
- ISO/IEC 17025 — Accredited laboratory competence (internationally valid test results).
- OHSAS 18001 — Legacy OH&S certification (maintained alongside ISO 45001 where required).
- ISIRI 14427 (Iran National Standard) — PE saddle clamps; verified performance at PN10/PN16. (For export, equivalent PN classes apply.)
Product Range & Typical Uses
- Compression fittings (threaded, no welding): 16–110 mm, 6–10 bar — drip-irrigation networks.
- Butt-fusion fittings (CNC-controlled thermal fusion): 63–800 mm, up to 20 bar — potable water and municipal sewer mains.
- Electrofusion (internal-coil couplers): 20–400 mm, up to 25 bar — gas service tees and petrochemical networks.
- Saddle clamps (EPDM O-ring): 63–315 mm, 10 bar — line repair and air-valve installation.
- Drip-irrigation components (push-fit/threaded): 16–32 mm — greenhouse flow control.
Technical & Execution Advantages
- Pressure ratings up to 25 bar for high-head pumping systems.
- UV resistance via 2.5% carbon black masterbatch.
- High flexibility—fewer handling and installation breaks on uneven terrain.
-
50-year design life at 20 °C with 1.25 safety factor (when installed per standards).
- Chemical compatibility for industrial effluent, brine, and liquid fertilizers.
Pre-Installation & After-Sales Support
- Free hydraulic consultancy: economic diameter selection and headloss calculations.
- Welder training workshops with skill certificates.
- Spare parts supply for fusion machines and periodic calibration.
- Digital order tracking: real-time production and dispatch status.
- Guaranteed virgin raw materials; acceptance of random destructive tests on site.
Proven Track Record
From national dam water-supply schemes to steel-industry water-transfer pipelines inside Iran, Kaveh Gostar systems have delivered up to 90% leakage reduction versus aged steel lines, easier maintenance, and seismic resilience.
Pricing Policy
Raw-material indexed pricing with tiered discounts for project volumes (per-ton consumption). This approach improves competitiveness and supports precise budget planning.
