The stainless steel threaded pipe nipple is a high-pressure forged pipe fitting widely used to connect pipes, valves, instruments, and equipment in industrial piping systems. Manufactured from premium stainless steel materials through precision forging and CNC machining, this SS pipe nipple provides excellent corrosion resistance, mechanical strength, and reliable sealing performance in demanding environments.
This stainless steel pipe nipple features precision external threads on one end with a plain end or threaded connection depending on application requirements. It is designed for quick installation and secure connections in pipelines where welding may not be convenient or space is limited.
Produced according to international standards such as ASME B16.11, BS 3799, JIS B2316, and GB/T14383, the NPT threaded pipe nipple is commonly used in oil & gas pipelines, petrochemical processing systems, marine engineering, power plants, and industrial fluid transportation networks.
Due to its robust forged construction and precision threading, the SS threaded pipe nipple ensures reliable performance in high-pressure piping systems, making it an essential component in modern industrial piping installations.

In industrial piping systems, pipe nipples are available in several types depending on the connection method and application.
Threaded Pipe Nipple
Threaded on both ends for direct pipe-to-pipe connections.
Single Threaded Pipe Nipple
Threaded on one end and plain on the other end for flexible installation.
Close Pipe Nipple
Short nipple with minimal unthreaded area.
Hex Pipe Nipple
Hexagonal center section allowing easy installation with a wrench.
Among these types, the stainless steel threaded pipe nipple is one of the most commonly used fittings in high-pressure industrial pipelines.
