Seamless steel pipes are manufactured without any welding seam or joint. They are produced by extruding the metal to the desired length and shape. Seamless pipes are generally considered stronger and more reliable because they don't have welds, which can be potential weak points. They are often used in high-pressure and critical applications.

A stainless steel flange is a mechanical component used to connect pipes, valves, pumps, and other equipment in a piping system. Flanges are usually made of stainless steel or other materials like carbon steel and come in various sizes and types. Stainless steel flanges are preferred in applications where corrosion resistance is essential, making them suitable for industries like chemical processing, food and beverage, pharmaceuticals, and marine environments.

The best way to avoid common mistakes in pipe welding is to understand the process and working conditions associated with the process.
