Alloy steel socket weld flanges are robust components used to join pipes, valves, or other equipment in a piping system through a socket welding process. These flanges are designed with a socket that the pipe or fitting is inserted into, and then welded around the circumference to create a strong and leak-proof connection. The use of alloy steel, such as ASTM A182 F11, F22, and A350 LF2, enhances the mechanical properties of the flanges, including their strength, durability, and resistance to high temperatures and corrosive environments. Socket weld flanges are commonly used in high-pressure and high-temperature applications, such as in the oil and gas industry, chemical processing, and power generation, where reliability and performance are crucial. Their design also allows for easy installation and alignment, making them a popular choice for demanding applications.
