What Is Stainless Steel 304 Flanges?

by Suraj C

Due to its physical qualities, such as corrosion resistance, longevity, and high strength, stainless steel 304 is one of the most widely used metals today and is frequently referred to as other metals. Among the many products created from this alloy that is used in the commercial, industrial, and residential sectors are Stainless Steel 304 Flanges. This metal comes in a variety of sizes and forms. This article looks at eight different flange types and how they are used.

Stainless steel flange types and applications:

  • To make them simpler to slip over the pipes, slide-on flanges have a little bigger diameter than pipes. These are the least expensive flanges that can be bought. These stainless steel Slip-On flanges are suitable for low-pressure applications and are fillet welded to a spot.
  • Weld Neck flanges are distinguished by their protruding neck and have the same thickness and angle as pipes and fittings. Weld Neck Flanges are advised for usage in sub-zero or highly hot and pressurized situations.
  • Socket Weld flanges can be used to join high-pressure pipes with extremely small diameters. Interior welds in socket weld flanges boost the structure’s load-bearing capacity. These types of flanges are utilized in the production of chemicals.
  • This kind of flange is used to seal vessels or pipe systems that need constant monitoring and has no bore. Blind flanges are suitable for use in pipe or tank systems that require continuous monitoring. Blind flanges negate the need for hubs. Stainless steel 304 blind flanges can withstand high compressive stress.
  • Lap Joint flanges, also known as slip-on fittings, are utilized with stub ends. For instance, lap joint flanges are an excellent option for low alloy steel pipes, carbon steel pipes, or pipelines that need routine maintenance.
  • Steel flanges called orifice flanges are used to meter liquids and gases. There are orifice plates or flow nozzles on the orifice flanges.
  • An essential For screwed flanges, a thread is present within the flange bore that matches a corresponding male thread on the pipe. In specialized applications, floating flanges are frequently utilized, and their installation doesn’t involve welding. Flanges made of stainless steel 304 are appropriate for pipes with exterior threads.
  • Ring-Type Joint Flanges are necessary for high-temperature and high-pressure applications. A groove that is particularly fashioned into ring-type joint flanges can conveniently collapse on a blind, slip-on, or welding neck flange. Leaks can be avoided when high-pressure and high-temperature media are delivered by attaching flanges to pipelines.

Stainless Steel Flanges Uses

  • Filters and pressure vessels
  •  as well as every type of valve
  •  fitting, and unique object 
  •  connected to pipes using flanges.
  •  Making a “blind flange” might be connected to a cowl plate
  •  The flanges are fastened together using bolts, and further sealing is frequently added using gaskets or other techniques.
