Behtarashan Sepahan Industries Group (BTS) has been a cornerstone of Iran’s brass and multilayer piping market for nearly three decades. A plant of 20,000+ m², about 500 specialists, CNC transfer lines, multi-hundred-ton hot-forging presses, and accredited laboratories enabled BTS to earn the first national standard mark for multilayer fittings. The blend of engineering depth, knowledge-driven manufacturing, and a domestic supply chain reduces import dependence and stabilizes supply.
Manufacturing Infrastructure & Technological Advantages
- Hot forging instead of casting: Multi-hundred-ton presses compact brass uniformly. The result is refined grain structure and higher pressure resistance versus cast parts.
- Precision CNC machining: After forging, threads and sealing surfaces are finished on multi-axis machines. Sub-0.05 mm tolerances drive initial leakage toward zero.
- In-house laboratory: PEX-b/AL/PE-RT pipes and press/coupling fittings undergo cyclic pressure/temperature testing before dispatch. Continuous MTTF monitoring supports a 50+ year service life.
BTS Product Portfolio & Applications
Five-Layer Pipes (PEX-b/AL/PE-RT)
- Sizes 16–63 mm for potable hot/cold water, radiator risers, and underfloor heating
- Longitudinal aluminum layer with ultrasonic weld for a 100% oxygen barrier and minimal pressure drop
- Continuous service up to 90 °C; nominal pressure 10 bar (PN10)
Press Fittings
- 304 stainless-steel sleeve with visual indicator for full pressing
- Dual EPDM O-rings, rated −30 to +110 °C
Coupling & Threaded Fittings
- Re-assemblable; ideal for small repairs without cutting pipe
- Forged brass nut with ISO 228 threads for global compatibility
Brass Valves
- Lever-handle ball valves PN16, thermostatic radiator valves, spring check valves, and more
- Nickel–chrome plating ~12 µm average for 240 h salt-spray resistance
Manifolds & Accessories
- Anodized aluminum manifold with clear flow meters for setting flow
- 24 V electric actuators for room-by-room UFH automation
Standards & Management Systems
- ISO 9001:2015 Quality Management

Technology Comparison with Market Alternatives
- Hot-forged brass vs. cast: higher structural integrity
- Visual press-completion indicator for safer commissioning
- ISO 228 threading for international fit-up
- Durable Ni–Cr plating and proven salt-spray endurance
- Rigorous lab testing and documented MTTF
Technical Solutions for Building Projects
- Underfloor heating in high-rises: Lower dead load than steel piping improves seismic safety margins.
- Upgrading legacy potable networks: Oxygen barrier reduces corrosion in existing cast-iron/steel components—ideal for hotels and hospitals with central plants.
- Light-industrial sites, mildly corrosive media: CW617N brass resists scale and hard-water deposits, extending service intervals.
Innovation, Sustainability & Future Outlook
BTS allocates part of its operating profits to R&D every year. Current projects: FKM O-rings for high temperatures, lightweight composite manifolds, and eco-friendly PVD coatings—steps that cut maintenance and extend system life.
