Inlet Adopter Castings are components used in various industries, particularly in fluid handling systems, to connect pipes or equipment with different diameters or connection types. These castings typically feature a tapered or stepped design to smoothly transition the flow of fluid from a larger diameter to a smaller one or vice versa. They are commonly used in industries such as water supply, wastewater treatment, chemical processing, and oil and gas. Inlet Adopter Castings are designed to accommodate different pipe sizes or connection types at the inlet of equipment, valves, pumps, or piping systems.
