The primary constituents in the alloyation of Stainless Steel 317L consist of 16% to 26% chromium and 6% to 22% nickel, which contribute to better resisters of pitting and crevice corrosion and overall strength. Our comprehensive range of Stainless Steel 317L Flanges comes with different types to suit our clients' diversified requirements. Be it Stainless Steel 317L Slip-On Flanges, Threaded Flanges, Weld Neck Flanges, or Blind Flanges, we offer a range of products that meet different operational requirements. Each type of flange serves a certain function in piping systems and, therefore, provides a solution for both structural integrity and operational efficiency in a piping system.

The Stainless Steel 317L Slip-On Flange is designed to allow the pipe to slip onto the flange before welding. It allows for a connection that is accurate and secure. Our Slip-On Flanges are used in an application that requires components that have reliable and easy installation techniques. On the other hand, the Stainless Steel 317L Threaded Flanges have internal threads that enable them to be connected easily to pipes with male threads. This offers an easier way in cases where welding cannot be done.

This is a stainless steel 317L weld neck flange used for high-strength applications where strong joints are needed to face heavy pressures and temperatures. Characteristically, these flanges have a long, tapered hub that serves to spread stresses evenly and thus gives integrity to the connection. Besides, our Stainless Steel 317L Blind Flanges are used to seal the end of pipes and hence offer a very tight closure, whenever there is a need for future access or maintenance. The flanges are normally used as closures at the end of pipelines and systems in which flow is shut off.

The Stainless Steel 317L Socket Weld Flanges render robust and safe connections for pipes under high pressure. Added to the above, our Stainless Steel 317L Lap Joint Flanges and Ring Type Joint Flanges offer extra flexibility in piping assembly and are highly recommended for ease of maintenance and assembly. One of the properties that makes Stainless Steel 317L Flanges notable is their resistance to extreme conditions. This grade has great performance in highly exposed chloride environments and finds applications in the chemical and petrochemical industries. It can resist very aggressive chemicals, especially during oil and gas extraction, processing of chemicals, and control of pollution.
