The 321 stainless steel socket weld cap is a crucial fitting used to seal the end of a piping system, preventing flow through the pipe. Made from 321 stainless steel, which includes titanium for enhanced resistance to intergranular corrosion, this cap is designed to withstand high temperatures and corrosive environments. The socket weld design ensures a secure, leak-proof connection, making it ideal for demanding applications in industries such as petrochemical, chemical processing, and aerospace. The forging process used in manufacturing this cap imparts superior mechanical properties, ensuring durability and strength under high pressure and mechanical stress.
