Flange&Pipe Fittings
ASTM A182 Pipe Fittings
ASTM A182 is standard specification for forged or rolled alloy & stainless steel flanges, forged fittings, and valves for high-temperature service.
They are widely used in petrochemical, oil & gas, power generation, chemicals, and paper manufacturing. We use the forged steel fittings and flanges to connect tubes in variety of industrial applications such as plumbing, heating, fluid distribution, air pressure lines and air conditioning.

Process
Process: The low-alloy ferritic steels shall be made by the open-hearth, electric-furnace or basic-oxygen process with the option of separate degassing and refining processes in each case. The stainless steels shall be melted by one of the following processes: Electric-furnace (with the option of separate degassing and refining processes), vacuum-furnace or one of the former followed by vacuum or electroslag-consumable remelting.
Heat Treatment: After hot working, forgings shall be cooled to a temperature below 1000 °F (538 °C) prior to heat treating in accordance with the requirements of ASTM A182. The low-alloy steels and ferritic and martensitic stainless steels shall be heat treated in accordance with the requirements of ASTM A182.
