Stainless Steel Flanges Manufacturer

Specialized Stainless Steel Flanges Manufacturer, ASTM A182 Flanges Dimensions.

Marcel Piping Projects Supply PVT LTD is one of the prominent manufacturers and exporters of SS Flanges, Which have only moderate resistance to carbon immersion and aren’t suggested for its application in largely carbonizing atmospheres. When frequent thermal cycling is involved in these Stainless Steel Slip-On Flanges are resistant to about 1850 Deg F. The high chromium and low nickel contents of SS Threaded Flanges supply good resistance to high-temperature sulfur-bearing atmospheres. Frequently in multiple product types, the size and carbon content can meet the demand of these SS Weld Neck Flanges. We also offer the same in different grades similar as Stainless Steel Flanges, Stainless Steel 304 Flanges, Stainless Steel 304l Flanges, Stainless Steel 316 Flanges, Stainless Steel 316l Flanges, Stainless Steel 321 Flanges, Stainless Steel 347 Flanges, Stainless Steel 347h Flanges, Stainless Steel 904l Flanges, and more. Dragged exposure to the 1100 Degree F – 1600 Degree F temperature range in these Stainless Steel Blind Flanges will bring some sigma to form, lowering room temperature flexibility and impact resistance. These SS Ring Type Joint Flanges also offer good resistance to a number of other inorganic acids similar to phosphoric acid and maximum organic acids.

We are leading Stockists and Suppliers of ASTM A182 Stainless Steel Flanges in USA, UK, Qatar, Mexico, Nigeria, Saudi Arabia, Kuwait, Iran, Kazakhstan, Bahrain, Vietnam, Indonesia, Norway, Ghana, Colombia, Azerbaijan, Libya.

How To Order Stainless Steel Flanges?
Parameters to request estimates

  • Flange type (welding neck, slip-on, threaded, lap joint flange, etc)
  • Stainless Steel Flange specification (example ASME B16.5, ASME B16.47 type A, EN 1092-1, JIS, UNI, DIN, etc.)
  • Nominal pipe size (NPS)
  • SS Flange rating (or class): flanges’ rating can range from 150 to 2500 for ASME flanges, from 5k to 30k for JIS B2220 flanges and KS1503 flanges; from PN 6 to PN 100 for European and Russian-standard flanges (DIN, UNI, EN 1092-1, GOST 12820 / 12821-80); Class 600/3, 1000/3, 1600/3, 2500/3, 4000/3 for SANS/SABS flanges (South African standard for flanges)
  • Pipe schedule (for welding neck and socket weld flanges)
  • Stainless Steel Flange facing type (FF; RF, RTJ): according to ASME B16.5, the raised face is the standard facing for flanges (different facings, like RTJ or flat face FF, have to be ordered specifically)
  • Stainless Steel Flange surface finish (smooth, stock, concentric serrated, etc)
  • Material grade of Stainless Steel
  • SS Flange Quantity
