You can get a better understanding of the SUS 321 Stainless Steel Flange here.
Butt-welded flanges boast a beveled end that is welded directly to the pipe, ensuring a strong and seamless joint. The two main types within this category are the weld neck flange (WNF) and the long weld neck flange (LWNF). Weld neck flanges offer high resistance to deformation and are ideal for high-pressure applications, while long weld neck flanges are used in situations requiring additional extension and reinforcement.
Threaded flanges come with internal threads, allowing for easy installation onto externally threaded pipes or fittings. They are particularly suitable for low-pressure systems and areas where welding is not preferred or possible.
Blind flanges, also known as blanking flanges, are solid plates used to seal the end of a piping system. They serve to block off pipes or valves temporarily and are crucial in maintenance and inspection operations.
