The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters. just like a unequal tee, the reducing cross connect the pipes of different diameters.
Since the pipe cross has four ends, when describe a reducing cross people should indicate all the four ends diameters and their positions, or else it may bring som misunderstanding.Type:Butt weld (BW), Seamless, Reducing crossStandards:ASME / ANSI – B 16.9 ASTM A403 – ASME SA403 – ‘Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings’ API 590-605 ASME B16.9 – ‘Factory-Made Wrought Buttwelding Fittings’ ASME B16.25 – ‘Buttwelding Ends’ ASME B16.28 – ‘Wrought Steel Buttwelding Short Radius Elbows and Returns’ MSS SP-43 – ‘Wrought and Fabricated Butt-Welding Fittings for Low Pressure, Corrosion Resistant Applications’Dimension:ANSI B16.9, ANSI B16.28, MSS-SP-43 Type A, MSS-SP-43 Type B, JIS B2312, JIS B2313Thickness:Schedule 5S, 10S, 20S, S10, S20, S30, STD, 40S, S40, S60, XS, 80S, S80, S100, S120, S140, S160, XXS and etc.Schedule:

Applications of pipe cross: Pipe cross are widely used in various commercial and industrial applications. Industrial applications include: Chemical processing, Petroleum, Pulp/paper, Refining, Textile, Waste treatment, Marine, Utilities/power generation, Industrial equipment, Automotive, Gas compression and distribution industries.
Pipe cross are also recommended for industrial plant fluid power systems.
