Product Description

ASTM B366 is a specification for nickel-iron-chromium alloy fittings, including elbow butt weld fittings, made from Incoloy 800H material. Incoloy 800H is a high-temperature alloy that offers excellent resistance to oxidation, carburization, and other forms of high-temperature corrosion.

These fittings are commonly used in demanding applications such as chemical processing, heat treating, and power generation due to their superior performance in extreme conditions.

Common Types

90-degree long radius elbow: Provides smoother flow and reduces pressure drop in piping systems
90-degree short radius elbow: Compact design ideal for tight spaces
45-degree long radius elbow: Allows gradual direction change when 90-degree turns aren't possible
45-degree short radius elbow: Space-saving design that reduces pressure drop
