Threaded Flanges

About

Threaded flanges are used in piping systems where a threaded connection is preferred instead of a welded one. That gives threaded flanges a very different role from blind, weld neck, slip on, lap joint, and socket weld flanges. Buyers usually look for threaded flanges when the piping system is already built around threaded pipe connections and the goal is to create a bolted flange connection without switching over to a welded flange style. PipingNow offers threaded flanges in the stainless steel grades and pressure classes shown in this collection, including 150#, 300#, and 600# options in 304L stainless steel and 316L stainless steel. For customers shopping specifically by flange type, a dedicated threaded flanges page makes it easier to compare the correct products by class, size, and stainless grade without sorting through unrelated flange styles. Built for Threaded Piping Connections The defining feature of a threaded flange is the connection style itself. Instead of being welded onto the pipe or used as part of a stub end assembly, a threaded flange is selected when the piping system calls for a threaded connection. That makes threaded flanges a practical option for installations where welding is not part of the planned connection method and where the specified piping layout is already based on threaded components. Threaded flanges are often used for: threaded stainless steel piping systems smaller-size industrial piping runs maintenance and replacement work systems where welding is not the preferred connection method service conditions requiring 150#, 300#, or 600# class options applications where the flange type needs to match an existing threaded system design Threaded Flanges by Class and Material Threaded flange selection usually starts with pressure class, nominal size, and stainless grade. This collection includes 150#, 300#, and 600# threaded flanges in 304L stainless steel and 316L stainless steel. Keeping threaded flanges grouped under their own type
