Stainless Steel 304l Flanges

What are Stainless Steel 304L Flanges?

ASTM A182 Grade F304L material is the low carbon version of the 304 grade stainless steel. The stainless steel 304L flanges are known for offering excellent corrosion resistance in a wide range of atmospheric temperatures. Flanges made with the ASTM A182 Grade F304L material are known to have high strength and great low-temperature properties. The 304L stainless steel threaded flanges (NPT) are also available at a very affordable cost.

The ASTM A240 F304L plate flanges looks like a disc and is welded to the end of a pipe so that it can be bolted to another pipe. The SA 182 Gr F304L forged flanges are metal disc which is installed at the tube, valve, or other components of the piping system. The pipe is inserted through the socket of a SA 182 F304L socket weld flange and it is secured by one fillet weld which is located on the exterior of a flange hub.

The F304L stainless steel RTJ flange can be described as a machine metallic ring which has deep groove cut into its face. The Inox 304L Ring Type Joint Flange is ideally used for high temperature and/or high pressure piping applications. The 304L stainless steel slip on flanges are ring placed on the end of a pipe. The flange face extends from the end of the pipe to a distance that is enough for applying the weld bead on the inner diameter.

The stainless steel 304L screwed flanges uses a screw thread for connecting a flange to the pipe. The AISI 304L reducing flanges can be widely found in oil and gas production companies. The SUS 304L SORF Flanges are mostly used for medium to low pressure pipelines. The UNS S30403 Lap Joint Flanges comes with a stub end which has a lap-joint flange placed over it. The stainless steel 1.4307 weld neck flanges are used for severe and critical conditions, like wide fluctuations in temperature and pressure, volatile and hazardous fluid environments, etc.

SS 304L Blind Flanges types

Two types of 304L stainless steel blind flanges are the most common: raised face blind flange and flat face blind flange.

Difference between A182 Gr F304L Reducing Flanges and Lap Joint Flanges

The stainless steel 304L reducing flanges helps to connect two pipes with different bore sizes. The SA182 F304L Lapped joint Flanges connect is ideal for large and hard-to-adjust flanges.

What is SA 182 304L WNRF Flange?

The stainless steel 304L WNRF Flanges are the weld neck raised face flange produced via forging methods. These ASTM A182 F304L flanges are joined to the pipes with the help of buttwelding. It is expensive and preferred for high pressure applications.
