ASTM A182 is the Standard Specification for Forged Stainless Steel Pipe Flanges and Stainless Steel Forged Fittings.ASTM 182 is use in pressure systems, Included are flanges, fittings and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications.
Stainless steel flanges play a crucial role in piping systems, providing a means for connecting pipes, valves, pumps, and other equipment. ASTM A182 Stainless Steel Flanges are designed to withstand high-temperature and corrosive environments, making them suitable for applications in industries such as petrochemical, chemical processing, oil and gas, and power generation.


Material Grades:
ASTM A182 includes various stainless steel grades, such as 304, 316, 317, 321, 347, and others. The specific grade selected depends on the intended application and the required mechanical and corrosion-resistant properties.
