Stainless steel weld neck flanges create a seamless weld by perfectly conforming to the pipe’s wall thickness and taper. They are designed with a diameter that fits perfectly inside the pipe and are used to transfer pressure from the flange to the pipe. Applications for steel flanges typically involve high-pressure environments. They are frequently used in such environments and are known as the most commonly preferred flange style. Stainless steel threaded pipe flanges, on the other hand, offer a unique and practical solution by eliminating the need to weld them to the pipe. These feature external threads and are generally ideal for high-pressure, small-diameter projects.

Stainless steel slip-on flanges are available in both large and small sizes. Their slightly larger diameter than the pipe allows them to slide easily over the pipe. After the slip-on process, these flanges are joined using fillet welds. This type of slip-on flange comes in two different types—ring and hub flanges—and may vary depending on their dimensional specifications.

Stainless steel flanges are typically used with a stud or bolt. Because they are easy to install and align, these types of flanges are preferred for low-pressure applications or in locations requiring frequent installation. Stainless steel blind flanges are used to seal off pipelines, pumps, or valves and are ideal for blocking flow. They can also be used to test the pressure of liquids or gases flowing through a pipe and sometimes serve as inspection covers. They are easy to manage and can be reversed to allow for expansion.
