ASME B16.5 Class 300 Socket Weld Flanges are ideal for moderate-pressure piping systems that require a strong, leak-proof, and compact connection. These flanges are commonly referred to as SWRF Flanges #300 (Socket Weld Raised Face) and SWFF Flanges #300 (Socket Weld Flat Face). Designed for smaller pipe sizes, socket weld flanges offer enhanced structural strength due to their welded socket connection, making them suitable for high-integrity flow systems. At Tesco Steel & Engineering, we manufacture top-quality Class 300 socket weld flanges in full compliance with ASME B16.5 standards, ensuring excellent performance in critical industrial applications.
Produced in our high-tech Mumbai manufacturing facility, these flanges are crafted using advanced CNC machining, automated welding processes, and rigorous quality inspection systems. Tesco Steel & Engineering is known for its superior quality manufacturing, delivering socket weld flanges that offer outstanding dimensional accuracy, corrosion resistance, and pressure containment. We offer Class 300 socket weld flanges in a range of materials such as stainless steel, carbon steel, and alloy steel, all customized to meet the unique needs of different industries and projects.
Tesco Steel & Engineering proudly exports ASME B16.5 Class 300 socket weld flanges to several international markets, including the USA, Germany, France, Italy, Saudi Arabia, UAE, and Oman.
