Stainless steel 304, 316, 904L butt weld flanges

2026-01-26View Original

Thread Content

A butt-weld flange is a pipe fitting with a neck and a circular tube transition structure, which is joined to pipes by welding; it is primarily used in high-pressure, high-temperature, or medium-sensitive piping systems. Its trumpet-shaped transition neck design keeps the weld joint away from the sealing surface, which helps reduce welding deformation and improve sealing performance; it is suitable for pressure ratings ranging from PN2.5MPa to PN400 and above.
