ASTM B564 UNS NO8811 Fittings

ASTM B564 UNS NO8811 fittings refer to a specific type of alloy used in the manufacturing of industrial piping systems, particularly for high-temperature and high-pressure applications.

ASTM B564 is an American Society for Testing and Materials (ASTM) standard that covers seamless and welded nickel alloy pipe fittings. These fittings are used in a variety of industries including petrochemical, oil refining, power generation, and nuclear.

UNS NO8811 refers to the material designation under the United States National Stock Number System, which indicates that this is a specific grade of Inconel alloy. Inconel 825, or UNS NO8811, is a nickel-chromium-molybdenum alloy known for its corrosion resistance, especially against sulfuric acid, hydrochloric acid, and other aggressive chemicals. It also has good mechanical properties at both high and low temperatures.

The fittings made from UNS NO8811 are designed to withstand various types of corrosion, including crevice corrosion, pitting, and stress-corrosion cracking. They are often used in chemical processing plants, heat exchangers, and reactors where there is a need for long-term reliability and durability.

These fittings can be in various forms such as elbows, tees, reducers, and flanges, and they are crucial components in creating piping systems that ensure the safe and efficient flow of corrosive fluids.
