SS Flanges Manufacturer, Suppliers in Mumbai, Pune, India, Delhi, Ahmedabad, Hyderabad, Rajkot, Chennai, UAE

Fitwel Industries LLP is one of the prominent and well known SS flanges manufacturer & supplier in Mumbai India & in the global steel market. We are an ISO 9001: 2015 certified company. SS flanges is a forged or a cast ring that is designed to connect sections of a pipe or any other machinery that requires a intermediate connecting point. Some of the basic types of flanges that have an enormous demand thats is SS flanges. SS flanges can be readily braked or roll-formed into a various forms that are to be used for applications in the industrial, architectural, as well as transportation fields.

SS flanges also has outstanding welding characteristics. Post-weld annealing treatment in the SS blind flange is not required while welding thin sections. Although Heavy welded sections in SS flanges may require a post-weld annealing treatment in order to achieve maximum corrosion resistance. A182 SS delivers excellent performance across a broad range of corrosive mediums and many atmospheric environments. Although, the SS Flange is subject to general corrosion like pitting and crevice corrosion in warm chloride containing environments. Additionally, ASTM a182 SS flanges is also subjected to stress corrosion cracking above a temperature of 60 °C.

What Is ANSI flanges Pressure Rating Or Class?

Pressure rating is defined as the maximum allowed pressure that a flange can withstand at increasing temperatures. According to the ANSI/ASME B16.5 specification, there are seven flange pressure ratings: 150, 300, 400, 600, 900, 1500, and 2500.
The terms “pressure rating”, “class”, “#”, “Lb” or “Lbs” are interchangeable, i.e. they all refer to the same exact concept of pressure/temperature performance of a flange (and other equipment like valves, fittings, etc).

How To Select The Right flanges Rating?

  • Find the rating table that applies to your flange scrolling below (this depends on the material of the flange, as flanges with different material grades have different pressure ratings)
  • Determine the max working temperature in your piping system (i.e. select one line in the table)
  • Select a rating based on the maximum pressure you expect at that temperature level (i.e. select one column in that line)
  • How I Do Choose The flanges?

    Guidelines for Selection of Various Types of flanges:

  • Pressure Temperature Rating of flanges.
  • Flange Dimensional Standards.
  • Flange Facings.
  • The bore of Welding Neck flanges and Hub Design.
  • Flange Material Limitations.
  • Iron flanges.
  • Carbon Steel flanges.
