ASME B36.10 ASTM A790 UNS S31803 Duplex Steel Pipe Nipple
Pipe nipples are short lengths of pipe that typically feature threaded ends, designed for connecting two other fittings or pipes within a piping system. They are essential components in various industries, providing efficient and reliable connections for fluid and gas transport. The simple yet effective design of pipe nipples allows them to be used in a wide range of applications—from domestic plumbing to complex industrial systems.

Common Types of ASTM A790 Pipe Nipples
Threaded Nipples: Male threads on both ends for easy installation with female-threaded joints.
Plain Nipples: Smooth ends for welding or other connections.
Custom Lengths: Can be fabricated in various lengths, depending on specific project requirements.
When selecting ASTM A790 pipe nipples, it's essential to consider:
Pressure Rating: Ensure the nipple can handle the intended pressure.
Environment: Consider potential corrosion factors, especially in marine or chemical environments.
End Connections: Threaded, welded, or flanged, based on your system design.
Applications
1. Connection of Pipes
Pipe nipples serve as connectors between two pipes, allowing for a seamless transition and extension of pipes in a system. This is especially useful in plumbing and industrial applications.
2. Fluid Transport
They are commonly used in systems that transport liquids and gases, including water supply, oil, and chemical lines, ensuring secure and leak-free connections.
3. Hydraulic Systems
Pipe nipples are critical in hydraulic systems, linking hoses and equipment to maintain fluid pressure and flow, essential for machinery operation.
4. Chemical Processing
In chemical plants, pipe nipples are used to connect various pieces of equipment and transport corrosive substances safely, often made from special materials like stainless steel for added durability.
5. Industrial Equipment
They are widely used in various industrial equipment applications, including compressors, pumps, and machinery, allowing for versatile assembly configurations.
6. Marine Applications
In marine environments, pipe nipples are often employed in plumbing and fuel systems, where corrosion resistance and reliability are critical.
