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.
Fitwel Industries LLP is a leading SS flanges Manufacturer in India. We provide all types of flanges such as Slip On flanges, Blind flanges, Threaded flanges, Weld Neck flanges, Long Weld Neck flanges, Lap Joint flanges, Socket weld flanges and all other types that are available in different grades. We manufactur SS flanges in Mumbai in all grades with high quality of material to manufacture the most durable and long-lasting flanges. Stainless Steel flanges are made up of different SS materials. The ASTM A182 SS flanges are made up of a super austenitic material that has good corrosion resistant properties with low carbon in its composition.
Buy online Stainless Steel Forged Flange at best price, Check Class 150 SS flanges Dimensions & SS ASTM A182 flanges Pressure Rating from 150 lbs to 2500 lbs.
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).
