Product Description: A 90 ° elbow is a type of pipe fitting used to change the direction of a pipeline, allowing fluids (liquids, gases, or powders) to achieve a 90 ° right angle turn in the pipeline….
90 Degree Elbow
The 90 Degree Elbow is one of the most commonly used pipe fittings in industrial piping systems. It is designed to change the direction of fluid flow by 90 degrees, allowing pipelines to achieve efficient right-angle turns while maintaining smooth flow performance.
As a critical component in pipeline networks, the 90° elbow connects pipes of the same or different nominal diameters and helps adapt piping layouts to various installation environments. It is widely used in construction, petrochemical, power generation, water treatment, shipbuilding, and mechanical engineering industries.
Product Features
• Efficient Flow Direction Change
Designed to redirect the flow of liquids, gases, steam, or other media by 90 degrees while maintaining reliable flow performance throughout the pipeline system.
• Long Radius and Short Radius Options
Available in Long Radius (LR) and Short Radius (SR) configurations to meet different installation requirements and flow characteristics.
• Multiple Connection Types
Offered with butt weld, threaded, and flanged connections for compatibility with various piping systems and operating conditions.
• Wide Material Selection
Manufactured from carbon steel, stainless steel, and alloy steel materials to suit different pressure, temperature, and corrosion requirements.
• Excellent Mechanical Strength
Produced with advanced manufacturing techniques to ensure dimensional accuracy, structural integrity, and long service life.
Types of 90 Degree Elbows
By Radius
Long Radius Elbow (LR Elbow)
The centerline radius is 1.5 times the pipe outside diameter (R = 1.5D).
Benefits:
• Lower flow resistance
• Reduced pressure loss
• Improved flow efficiency
• Suitable for most industrial piping systems
Short Radius Elbow (SR Elbow)
The centerline radius equals the pipe outside diameter (R = 1.0D).
Benefits:
• Compact structure
• Space-saving installation
• Ideal for confined areas
• Suitable for equipment piping and low-pressure systems
By Connection Type
Butt Weld Elbow
Connected to the pipeline through welding, providing excellent strength and leak-proof performance for high-pressure and high-temperature applications.
Threaded Elbow
Features threaded ends for easy installation and maintenance, commonly used in low-pressure and small-diameter piping systems.
Flanged Elbow
Equipped with flanges at both ends for convenient assembly and disassembly, making maintenance and inspection easier.
