Threaded nipples are short lengths of pipe with male threads at both ends, used to connect two female threaded fittings or other equipment with female Threads. Usually, they are constructed from stainless steel 304, also available in stainless steel 316.
Stainless steel threaded nipples are usually available in either internal or external threads and are used with other pipes or fittings with matching threads. Installation is relatively easy, they can usually be connected by turning and tightening the threads. Using stainless steel threaded joints, you can easily connect two pipes or fittings to form a tight connection without the need for welding.
Since the material used is corrosion-resistant and high-temperature-resistant 304 or 316 stainless steel, stainless steel threaded nipples are suitable for various environments and application fields, such as water supply systems, gas systems, chemical industry, petroleum industry, etc.
