Description
Carbon Steel Weld Lateral
Carbon Steel Weld Laterals are designed to provide a 45-degree branch connection in welded piping systems, allowing flow to divide or combine through a smoother branch transition than a standard 90-degree tee.
Manufactured from durable carbon steel, these butt weld laterals provide a permanent welded connection for industrial, commercial, mechanical, and process piping applications. Available in Standard and Extra Heavy options, they are ideal for systems requiring strength, weldability, and reliable branch-flow performance.

Lateral Configuration
Straight Run
Two opposing butt weld ends form the primary straight-through piping path.
45° Branch
The branch outlet enters or leaves the main run at a 45-degree angle for a more gradual directional transition.
Three-Way Flow
The fitting can be used to divide flow into an angled branch or combine compatible flow streams into the main run.
Construction Details
Carbon steel weld laterals are designed for installation between compatible butt weld pipe and piping components. Welding the fitting into the system creates a permanent connection without threaded joints.
The 45-degree branch configuration provides an angled flow path that can be useful where a more gradual branch transition is preferred over a conventional 90-degree tee.
Why Choose a Weld Lateral?
Smoother Branch Transition
- Provides a 45° branch angle
- Creates a more gradual directional change
- Useful where smoother flow transitions are preferred
- Supports angled branch-line routing
- Can simplify certain piping layouts
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

Frequently Asked Questions
What is a carbon steel weld lateral?
A weld lateral is a three-opening butt weld fitting that provides a branch connection at a 45-degree angle to the main piping run.
How is a lateral different from a tee?
A standard tee typically creates a 90-degree branch, while a lateral creates a 45-degree branch connection for a more gradual directional transition.
What type of connection does this fitting use?
This fitting uses butt weld connections and is welded to compatible carbon steel pipe or piping components.
What wall thickness options are available?
The supplied product information lists Standard and Extra Heavy options.
What material specification applies?
Seamless butt weld fittings conform to ASTM A/SA234 WPB through 24".
What dimensional standards apply?
The supplied information states that weld fitting dimensions conform to ASME/ANSI B16.9, B16.11, and B16.28 through 24", with fittings larger than 24" conforming to MSS-SP-48.
What is the maximum carbon content?
The supplied product information states that carbon content does not exceed 0.25% maximum.
Are Mill Test Reports available?
Yes. Mill Test Reports are available with every order according to the supplied product information.
What should I verify before ordering?
Confirm the main run size, branch size, required wall thickness, material requirements, and applicable piping-system specifications before ordering.
Important Ordering & Installation Notes
