Stainless Steel 347 Flanges

A stainless steel 347 flanges is a protruded rim that acts as an efficient component to connect piping equipment in the system. The SS 347 flanges are basic austenitic grade stabilized with niobium. The flange are easy to install and permit good inspection points allowing room to modify and clean them. They are designed to work in elevated temperatures above 1000 degrees F. The ASTM A182 F347 forged flanges possess superior strength and are produced at high-temperature conditions. These flange have good creep resistance and can be welded following standard shop fabrication procedures.

The ASME SA182 347 slip on flange is slipped on a pipe and welded on their interior and exterior with one or more fillet welds. These flange are favored by engineers in the gas and oil industries due to their lower costs compared to other flange types. DIN 1.4550 socket weld flanges have equal strength as slip on flange and can be connected with a singular fillet weld on their exterior. These flange are used in smaller sizes below 2 NPS and are seen in low-pressure setups. The UNS S34700 weld neck flanges are recognized by their long tapered hub that transfers the stress of the pipe to the hub. The weld neck type flange is suited across repeated bending conditions and is well versed for use in high-pressure environments. SS 347 Blind Flanges are characterized without a bore at the center. Their main purpose is to blank the ends of a piping system. The flange can terminate the flow of media and isolate the system. The 347 SS spectacle blind flange is a 2 component assembly designed with a spacer and a blank. The spacer allows for normal flow, while the blank cuts the flow. Spectacle flange are common in systems where repair takes place constantly.
