Concentric reducers connect two pipe sizes while keeping both pipe axes on one centerline. This category covers high-temperature Cr-Mo alloy steel and corrosion-resistant nickel-alloy butt-weld reducers for power, rafineri, petrokimya, marine and chemical service.Standard orders should identify the material grade, ASME B16.9 baskısı, büyük ve küçük uç boyutları, program veya tam duvar, seamless/welded construction, bevel and documentation. Check drainage and pump-layout requirements before choosing a concentric rather than eccentric reducer.
