Stainless Steel 317L Flanges

A stainless steel 317L flanges is a common method of connecting pipework to other materials in the piping system. The SS 317L flanges are made up of low carbon, nickel, chromium, molybdenum, and other strengthening alloys. The flange help in providing support to pipes as there is a movement of flow across different conditions. 317L stainless steel pipe flanges are designed in schedules from SCH 10 to SCH 160 and XXS. The 317l flange are available in pressures from class 150 to class 2000 or more. The flange have good corrosion resistance properties while exhibiting enhanced mechanical properties. The DIN 1.4449 flange connect valves, pipes, pumps, and other equipment to form an efficient pipeline. These flange allow for easy inspection and rapid modification in the system.

Check ASTM A182 F317L Slip On Flange Specification as per ASME B16.5

The UNS S31700 weld neck flange is a high-strength flange that reduces the stress on the component due to its long tapered hub. The weld neck flange is attached with the help of a standard butt-welding procedure. An ASTM A182 F317L slip on flange is favored in the oil and gas industry as they are cheap compared to weld neck flange. These flange are easy to install and are seen across low pressure and temperature environments. The SS 317L socket weld flanges have static strength similar to slip on flange and are connected with a single fillet weld. These flange are seen in small pipe bores of sizes below NPS 2. Due to their corrosion issues, they are not suited for certain processes. A 317L SS blind flange can be characterized without a bore and center. The main purpose of the flange is to blank off piping equipment in the system. These flange help terminate the flow of pressurized media in different applications.
