What Are Short Stub End Fittings?
Short stub end fittings are short pipe fittings used to connect pipes with lap joint flanges in industrial piping systems. They are welded to the pipe and work with a loose backing flange, which can rotate to simplify bolt-hole alignment during installation. Their compact length makes them suitable for piping arrangements where space is limited.
These fittings are commonly used in oil and gas, chemical processing, petrochemical, and marine industries. They are available in different material grades, sizes, and specifications to suit various piping requirements.
Short Stub End Fittings
Short Stub End Fittings are available in sizes from 1/2" to 48" and grades such as ASTM A234 WPB, WP5, WP9, WP11, WP22, and WP91. Designed for use with lap joint flanges, these fittings support reliable piping connections in oil and gas, petrochemical, refinery, and power generation industries.
