PIPE REDUCER As one type of industrial fittings, reducing pipe is mainly used for connection between two pipelines with different diameters. Generally, pipe reducers can be divided into concentric reducer and eccentric reducer. The former is often used on vertical pipelines, while the latter is usually installed on horizontal pipelines. Sometimes, flow rate can't change two much when the flow increases or decreases in a pipeline. The reducer is perfect for this situation. It is able to effectively prevent cavitation when installed in the inlet of a pump. The reducer is also needed at the joint points of an instrument such as flow meter or control valve to coordinate with the instrument.Pipe Reducer Standard:GB/T12459-2005, GB/T13401-2005, GB/T10752-2005 SH/T3408-1996, SH/T3409-1996 SY/T0609-2006, SY/T0518-2002, SY/T0510-1998 DL/T695-1999, DL/T473-1992 GD2000 GD87-1101 HG/T21635-1987, HG/T21631-1990 ASME B16.9-2007, ASME B16.25-2007 MSS SP 75-2008, MSS SP 43-2008 CSA Z245.11-05-2005 EN10253-1-1999, EN10253-2-2007, EN10253-3-2008, EN10253-4-2008 DIN2615-1-1992, DIN2615-2-1992 BS1640-1-1962, BS1640-2-1962, BS1640-3-1968, BS1640-4-1968, BS1965-1-1963 GOST17376-2001 AFNOR NF A 49-289-1990, AFNOR NF A 49-170-1-1999, AFNOR NF A 49-170-2-2009, AFNOR NF A 49-170-3-2009, AFNOR NF A 49-170-4-2009 ISO3419-1981, ISO5251-1981 JIS B2311-2009, JIS B2312-2009, JIS B2313-2009Available sizes range we can produce: DIMENSIONSSEAMLESS TEEWELDED/SEAMED TEEOUTER DIAMETER1/2"~32"6"~60"NOMINAL DIAMETER15MM~800MM150MM~1500MMWALL THICKNESS4MM~200MMPipe Reducer Material : Carbon steel: ASTM/ASME A234 WPB - WPC Alloy steel: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP 911 Stainless steel: ASTM/ASME A403 WP 304-304L-304H-304LN-304N ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H Low-temperature steel: ASTM/ASME A402 WPL 3-WPL 6 High-performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70
