Pipe Nipple ASME B16.11

Forged Hex Nipple Pipe Fittings| ASME 16.11, MSS SP-79, 83, 95, 97, BS 3799

A pipe nipple is a short length of pipe, typically used to connect two other fittings or pipes in a pipeline system. Known for its versatility, it is a key component in industries. They are often threaded on both ends to provide a secure, leak-proof connection. Available in seamless or welded forms, pipe nipples are designed to withstand high pressure and temperature, making them a reliable choice for both industrial and domestic piping needs.

A hex nipple is a specialized fitting featuring external threads on both ends with a hexagonal section in the middle. The hexagonal design allows for easy tightening or loosening using a wrench, making it an essential component for creating secure connections in piping systems. Hex nipples are commonly used to connect pipes or fittings of the same diameter. Their durability and resistance to corrosion ensure long-lasting performance, even in challenging environments.

A swage nipple is a reducer fitting that connects pipes or fittings of different diameters. With one end larger than the other, it facilitates smooth transitions between varying pipe sizes, optimizing flow and reducing turbulence. Swage nipples are available in concentric and eccentric types, catering to specific alignment and flow requirements.
