ASTM A182 Products
ASTM A182 Fittings
ASTM A182 fittings are used for joining or adapting pipes of different sizes or shapes within a piping system. These fittings include elbows, tees, reducers, couplings, and unions. With their excellent mechanical properties and corrosion resistance, A182 fittings provide leak-free connections and maintain the integrity of the piping system. These fittings can be butt-welded, socket-welded, or threaded, depending on the application requirements.
ASTM A182 Flange
ASTM A182 flanges are widely used in piping systems to connect pipes, valves, and other equipment. These flanges are available in various types, including welding neck, slip-on, blind, socket weld, threaded, and lap joint flanges. They are designed to withstand high-pressure and high-temperature environments, making them suitable for applications in oil and gas, petrochemical, power generation, and other heavy industries. The dimensional standards specified by ASTM A182 ensure the compatibility and interchangeability of flanges across different manufacturers.
