Product Description
Product Overview
Our Socket Weld Flanges are expertly forged from high-quality carbon steel (ASTM A105) and stainless steel (grades 304 and 316), designed to provide reliable, leak-proof connections in piping systems. Suitable for both carbon steel and stainless steel pipelines, these flanges offer excellent mechanical strength and corrosion resistance for various industrial applications.
The socket weld design allows for easy, welding-free installation, making them ideal for small to medium-sized pipe systems in oil & gas, chemical processing, water treatment, and other industries requiring secure and durable pipe fittings.
