Threaded Flanges by Pipes Fittings Supplier is India’s largest supplier, distributor, wholesaler and manufacturers of stainless steel products. Threaded pipe flanges are similar to slip-on pipe flanges except the bore of threaded pipe flanges that has tapered threads. These special types of threaded flanges are extremely helpful for high pressure heat and the key feature of this threaded flange are that it can be assembled without welding. Threaded flanges are mostly used in petro and chemical industry. Threaded flanges are also typically provided with a raised face, flat face or even a RTJ facing. The standard height of any Threaded Flanged is 1/6” under 400# it can also have a raised face height 1/4
With also provide high quality of flange consisting of tapered interior threaded design which is by connecting two exteriors to have a tight and leak proof seal. So these together create a seal weld where the pipe and flange meet together. Most of the time these flanges are used on the pipes containing very smaller diameter, these are actually very effective for complete piping solution. Some of the materials such as stainless steel are hard to create or make a successful weld and therefore these types of flanges are used to create a perfect seal over smaller or customized pipes. These are also called screwed flanges, threaded flanges, stainless steel screwed/ threaded flanges, SS Screwed or threaded flange. The size win which these are available can also be customized with (15 NB) to 48" (1200NB). The classes of these flanges are as 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6, 10, 16, 25 and 40. ANSI B16.5, ANSI B16.47, MSS SP44, ANSI B16.36, ANSI B16.48 are the standards name for these Threaded Flanges. The productions of these flanges include many types of flanges Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ). Coating/Surface Treatment treat can be applied easily with Anti-rust Paint, Oil Black Paint, Yellow Transparent, Zinc Plated, Cold and Hot Dip Galvanized. The grades for Stainless Steel Screwed/Threaded Flanges are named as ASTM A182, A240 F 304, 304L, 304H, 316, 316Ti, 316H, 316L, 316LN, 309S, 309H, 310S, 310H,317, 317L, 321, 321H, 347, 347H, 201, 202, 904, for Carbon Steel Screwed/Threaded Flange the grades are ASTM A 105, ASTM A 350 LF 2, ASTM A694 F52 - F60 - F65 - F70. Other type of flanges which also have certain effective high quality grades include Alloy Steel Screwed/Threaded Flanges and their grades can be compared with each other with ASTM A182 F1, F5, F9, F11, F22 and F91.
Nickel Alloy Screwed/Threaded Flanges also have grades which are particularly used in any industries like petro-chemical, oil, gas, power generation, bulk liquid transportation, Chemicals and other pharmaceutical.
