Product DescriptionSpecificationThreaded Reducing CouplingA Threaded Reducing Coupling is a type of pipe fitting designed to connect two pipes of different diameters in a straight line. The key feature of this coupling is that it has internal threads (female threads) on both ends, allowing it to be screwed directly onto externally threaded (male) pipes or fittings without the need for welding. Its primary purpose is to change the flow diameter within a piping system.Key Features:Function: The core function is flow reduction. It reduces the pipe size from a larger diameter to a smaller one, which can increase flow velocity or adapt to different equipment connections.Connection Method: As the name implies, it uses a threaded connection. This makes it ideal for low-pressure, non-critical applications where disassembly for maintenance or modification might be necessary.Design: It is a short, solid barrel-shaped fitting with a concentric bore. "Concentric" means the centerline of both the larger and smaller openings are aligned, resulting in a smooth, stepped reduction in diameter. Materials: Commonly made from malleable (forgeable) materials such as:Malleable Iron: A common, economical choice for many industrial applications.Carbon Steel: For higher strength and pressure ratings.Stainless Steel (e.g., 304 or 316): For superior corrosion resistance in chemical, food processing, or marine environments.Brass: Often used for water and gas lines due to its corrosion resistance and malleability.Thread Standards:The threads are typically cut to a standard profile to ensure a tight, leak-resistant seal. The most common standard is:NPT Advantages:Ease of Installation: Requires only simple tools (pipe wrenches) and no hot work permits like welding.Removability: The connection is not permanent, allowing for easy disassembly and reconfiguration of the piping system.Cost-Effective: Generally less expensive than welded alternatives and requires less skilled labor to install.Typical Applications:Threaded reducing couplings are widely used in a variety of low to medium-pressure systems, including:Water Supply LinesLow-Pressure Steam LinesHydraulic LinesFuel and Oil LinesChemical Processing Lines Air Compression SystemsIrrigation SystemsPacking & DeliveryWe adopt standard and strong export package for each batch of goods Company ProfileWuhan Hwanai Metal Casting Co., LtdWuhan Hwanai Metal Casting Co., Ltd. specializes in the production and export of power line hardware ,Pipe Fittings, Concrete Pump Pipe , Valves with over 20 years of experience in the industry.
