Stainless steel weld-neck flanges are the workhorses of high-pressure piping systems. They are excellent for use in fields requiring strong connection and corrosion resistance to high temperatures. The source of their power is in the unique design itself. Unlike other flanges, weld neck flanges have a conical transition, which makes a smooth connection to the pipe. By doing that, the stress is spread out all over, therefore, there are no weak spots or breaks. On the other hand, the weld between the flange and the pipe, also known as the neck, is extended, hence increasing the load-bearing capacity. Besides, stainless steel gives better corrosion resistance than carbon steel and as such, weld neck flanges are ideal for those environments which are harsh like chemical plants, marine applications and oil and gas refineries. There are different grades of stainless steel that you can choose from depending on the specific media and temperatures you need to work with. In the case of high integral piping systems, the stainless steel weld neck flanges remain the most durable and the most flexible option.
