Indus Industrial Group supplies heavy-duty Concentric and Eccentric HDPE Butt Fusion Spigot Reducers engineered across nominal pipeline diameters from DN63 to DN800 in pressure ratings SDR11 (PN16) and SDR17 (PN10) according to ISO 4427-3 and EN 12201-3 standards. Injection-molded from virgin PE100 black resin with long cylindrical spigots, concentric reducers provide smooth hydraulic transitions in pressurized water mains, while eccentric reducers maintain flat bottom inverts to prevent air pockets or sediment trapping in pump suction headers and gravity lines across Iraq.

Pump station suction and discharge nozzle diameter transitions, municipal water distribution size stepping, wastewater lift station headers, and industrial process cooling loops across Baghdad, Erbil, Basra, Mosul, and Karbala.
Concentric and Eccentric HDPE Butt Fusion Spigot Reducers represent the vital diameter transition fittings for pressurized water transmission, pump station suction/discharge headers, and industrial pipeline networks across Iraq. Governed by ISO 4427-3, EN 12201-3, and DIN 16963 standards, these fittings are produced from virgin pre-compounded PE100 resin. The concentric configuration provides a symmetrical conical transition that gently accelerates or decelerates fluid velocity, preventing turbulence, flow separation, and excessive head losses in municipal transmission mains.
The eccentric configuration features a flat side and an offset tapered side. In horizontal pump suction piping inside water treatment plants and booster stations in Baghdad, Erbil, and Basra, installing eccentric reducers with the flat side on top (flat-top) prevents air pocket accumulation that causes centrifugal pump cavitation. Conversely, in gravity drainage and slurry lines, installing eccentric reducers with the flat side on the bottom (flat-bottom) prevents sediment accumulation and maintains smooth invert flow.
Manufactured with extended spigot lengths on both small and large ends, these reducers clamp seamlessly inside hydraulic butt fusion machines or connect via electrofusion couplers. Staged at our Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies complete metric stepping matrices with full EN 10204 3.1 inspection certification.
Installing a concentric reducer on a horizontal suction line creates a high point where trapped air collects. When drawn into the pump, this air bubble causes cavitation, vibration, and mechanical seal destruction. An eccentric reducer installed flat-on-top maintains a continuous horizontal crown, completely preventing air pockets.
Yes. Indus injection-molded reducers are manufactured with full wall thickness profiles compliant with SDR11 (16 Bar) and SDR17 (10 Bar) without requiring any pressure down-rating factor.
Indus stocks concentric and eccentric reducers from DN63/50 up to DN400/315 in high volume, and large sizes up to DN800 at our Erbil, Baghdad, and Basra facilities for immediate nationwide dispatch.
