Socket Welding flanges have counter bore is sightly larger than the Outer Diameter of the matching pipe, allowing the pipe to be inserted. A restriction is built into the bottom of the bore, which acts as a shoulder for the pipe to rest on, and has the same ID of matching pipe. The innovative design of flanges ensure that flow is not restricted in any direction. We can offer socket welding flanges, steel welding flanges, stainless steel welding flanges in variety of specifications for application in different industries.
Socket Weld Flanges are similar to slip-on flanges, however, socket welds have an internal recess on the inside diameter to allow for a smoother flow of the process fluid. The positive of this is that is creates a smooth bore with the proper welding and grinding. The negative of this type of flange is that it can be more expensive than a slip-on due to more intricate machining, and they can be less readily available than slip-ons due to the fact that the bottom half of the inside diameter must be made to the same schedule as the pipe that is being used. (you must specify the schedule needed) These socket weld flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings. They are more used on lower pressure temperature as well today. Specialty Flange and Fitting, Inc. offers these flanges in stainless and alloy material.
