ASTM B366 NO8810 180° Elbow Long Radius Butt Weld Fitting

ASTM B366 NO8810 180° Elbow Long Radius Butt Weld Fitting

The ASTM B366 NO8810 180° Elbow Long Radius Butt Weld Fitting is a high-performance pipe fitting designed for critical industrial applications. Below is a detailed overview:

Material Standard: ASTM B366

• The fitting is manufactured according to the ASTM B366 standard, which specifies requirements for wrought nickel and nickel alloy fittings. These materials are known for their excellent corrosion resistance, strength, and durability in harsh environments, including chemical processing and marine applications.

Material Grade: NO8810

The grade NO8810 is commonly associated with Incoloy 825, a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium.

Key Properties:

• Corrosion Resistance: Exceptional resistance to reducing and oxidizing acids, including sulfuric and phosphoric acids.
• High-Temperature Resistance: Withstands elevated temperatures without compromising structural integrity.
• Mechanical Strength: High strength and toughness, making it suitable for demanding environments.

Fitting Type: 180° Elbow

The 180° elbow is a pipe fitting that allows for a complete reversal of flow direction (U-shaped).

Applications:

• Used where a smooth directional change of 180° is necessary.
• Ideal for tight spaces or looped piping systems in industries such as oil & gas, petrochemical, power plants, and desalination plants.

Long Radius Design

• The long radius (LR) design means the radius of the curve is 1.5 times the nominal pipe diameter (1.5D).
• Advantages:
  • Minimizes pressure drop and turbulence within the system.
  • Facilitates a smoother flow compared to short-radius elbows.
  • Reduces wear and tear on the piping system.

Butt Weld Connection

• The butt weld fitting allows for a seamless and strong connection to the pipe.
• Benefits:
  • Provides a leak-proof connection.
  • Ensures a smooth internal surface, reducing friction and flow resistance.
  • Suitable for high-pressure and high-temperature systems.

Key Features

• Manufactured to strict ASTM B366 standards.
• Superior corrosion resistance due to NO8810 (Incoloy® 825) material.
• Long radius design for enhanced flow efficiency.
• Durable and reliable butt weld connection.
• Suitable for extreme environments and demanding industrial applications.
