ASTM B366 Inconel 601 Stub End Manufacturer & Supplier
We are a trusted manufacturer and exporter of Inconel® 601 stub ends conforming to ASTM B366 standard. We supply both short pattern (Type B) and long pattern (Type A) stub ends for corrosive and high-temperature piping systems used in power generation, petrochemical, furnace, and thermal processing industries.
Our N06601 stub ends are precision-forged and machined to meet ASME B16.9 and MSS-SP-43 dimensional tolerances, ensuring a perfect match with lap joint flanges and stainless or nickel alloy pipes.
A Stub End is a type of pipe fitting used in piping systems to facilitate the connection of pipes to flanges. It is a short length of pipe with a flange welded onto one end, and the other end is designed for a butt weld connection to the pipe. Stub ends are commonly used in conjunction with lap joint flanges to create a more flexible and cost-effective alternative to traditional flange connections.
