B16.9 Buttweld Pipe Fittings， ASTM B366 Incoloy 800H Nickel Alloy 180DEG. Elbow
ASTM B366 is a standard specification for factory-made wrought nickel and nickel alloy fittings. Incoloy 800H is a nickel-iron-chromium alloy that is part of this specification. Incoloy 800H elbow is specifically designed to withstand high temperatures and pressures， making it ideal for use in applications where the fluid or gas being transported is at high temperature and pressure. It also offers excellent resistance to corrosion and oxidation， which makes it suitable for use in harsh environments where other materials may corrode or degrade over time.

There are several types of elbows used in piping systems， including:
1. 45-degree elbow: This type of elbow changes the direction of flow by 45 degrees.
2. 90-degree elbow: This type of elbow changes the direction of flow by 90 degrees.
3. 180-degree elbow: This type of elbow changes the direction of flow by 180 degrees， effectively reversing the direction of flow.
4. Short radius elbow: This type of elbow has a shorter center-to-end distance than a standard elbow， making it ideal for use in tight spaces.
5. Long radius elbow: This type of elbow has a longer center-to-end distance than a standard elbow， which helps to reduce friction and pressure loss in the system.
Applications
Nickel alloy elbows are commonly used in piping systems for their excellent resistance to corrosion and high temperature environments. They are often used in industries such as petrochemical， chemical， and power generation. Some specific applications include oil and gas pipelines， chemical processing， and steam systems.
1. Marine engineering.
2. Chemical and hydrocarbon processing equipment.
3. Gasoline and freshwater tanks.
4. Crude petroleum stills.
5. De-aerating heaters.
