An A105 Water Treatment Flange is a forged carbon steel flange manufactured under ASTM A105 specifications, designed for connecting pipes and equipment in water treatment plants and distribution systems.
ASTM A105 carbon steel provides high strength, durability, and resistance to pressure, making it suitable for pipelines carrying treated, raw, or process water under varying conditions.
They are used in water treatment plants, desalination units, filtration systems, wastewater treatment facilities, and municipal water supply pipelines.
They are manufactured in ANSI/ASME Classes 150# to 2500#, depending on the pressure and flow requirements of the water treatment system.
