Description
Carbon Steel Weld 90° Elbow Long Radius
Carbon Steel Weld 90° Long Radius Elbows are designed to change the direction of a piping system by 90 degrees while providing a broader, more gradual turn than a short radius elbow.
Manufactured from durable carbon steel, these butt weld elbows provide a permanent welded connection for industrial, commercial, mechanical, structural, and process piping applications. Available in Standard, Schedule 160, Extra Heavy, and Double Extra Heavy options, they are ideal for systems requiring strength, weldability, and smooth directional routing.

Long Radius Elbow Configuration
90° Direction Change
The elbow redirects the piping system through a right-angle turn.
Long Radius Design
The broader bend profile provides a more gradual directional transition than a short radius elbow.
Two Butt Weld Ends
Both ends are designed to weld directly to compatible carbon steel pipe or piping components.
Construction Details
Carbon steel weld 90° long radius elbows are designed for installation between compatible butt weld pipe and piping components. Welding both ends into the system creates a permanent directional connection without threaded or mechanical joints.
The long radius configuration provides a smoother turn through the 90-degree change in direction and is commonly used where additional installation space is available and a more gradual flow path is preferred.
Why Choose a Long Radius 90° Elbow?
Smoother Directional Change
- Changes pipe direction by 90°
- Long radius profile provides a broader bend
- Supports smoother directional flow
- Useful in process and mechanical piping layouts
- Provides a single-fitting right-angle turn
Permanent Welded Connection
- Designed for compatible butt weld piping
- No threaded connection required
- Suitable for industrial and mechanical piping systems
- Available in multiple wall thickness options
- Supports fabricated piping assemblies
Long Radius vs. Short Radius Elbows
Long Radius
A long radius elbow uses a broader curve to provide a more gradual 90-degree directional transition. It generally requires more installation space than a short radius elbow.
Short Radius
A short radius elbow uses a tighter bend profile and requires less installation space, making it useful where compact routing is the priority.
Typical Applications
Industrial & Mechanical Piping

Frequently Asked Questions
What is a carbon steel weld 90-degree long radius elbow?
A 90° long radius elbow is a butt weld fitting designed to make a right-angle directional change using a broad, gradual bend profile.
What does long radius mean?
Long radius refers to a broader bend configuration that provides a more gradual directional transition than a short radius elbow.
How is a long radius elbow different from a short radius elbow?
A long radius elbow uses a broader curve and generally requires more installation space, while a short radius elbow uses a tighter bend for compact piping layouts.
Why use a long radius elbow?
A long radius elbow is commonly selected where a smoother directional change is preferred and sufficient installation space is available.
