Long Radius 90° Design
The long radius design provides a gradual 90° change in direction compared with tighter-radius elbow configurations. This smoother transition helps promote more efficient flow and can reduce turbulence and pressure drop within compatible piping systems.
Long radius elbows are commonly used where maintaining smoother flow characteristics is important to system performance.
Butt Weld Connection
These elbows are designed for butt weld installation into compatible stainless steel piping systems. Proper fit-up and welding create a continuous welded connection between the elbow and adjoining pipe.
Review applicable welding procedures, pipe schedule, material grade, and system requirements before fabrication or installation.
Schedule 10 vs. Schedule 40
Schedule 10
- Lighter wall option for compatible piping systems
- Commonly used where lower wall thickness is appropriate
- Manufactured and tested to applicable ASTM and ASME requirements
- Confirm pipe schedule before ordering
Schedule 40
- Heavier wall than Schedule 10
- Suitable for applications requiring greater wall thickness
- Manufactured and tested to applicable ASTM and ASME requirements
- Confirm mating pipe schedule before welding

Frequently Asked Questions
What is a long radius 90° elbow?
A long radius 90° elbow changes the direction of a piping system by 90° using a gradual-radius bend to support smoother flow through the fitting.
What connection type is used?
These fittings use butt weld connections and are intended to be welded directly into compatible stainless steel piping systems.
What schedules are available?
The supplied product information lists Schedule 10 and Schedule 40 material options.
What material standard applies to the raw pipe?
The raw stainless steel material conforms to ASTM A312.
What manufacturing and testing standards apply?
The supplied product information specifies ASTM A403 and ASME SA403/SA403M.
What dimensional standards apply?
Wall thicknesses and applicable dimensions conform to ANSI B16.9, ANSI B16.28, and MSS SP-43.
Why choose a long radius elbow?
The gradual bend helps provide a smoother internal flow path than a tighter-radius directional change, which can help reduce turbulence and pressure loss.
Can Schedule 10 and Schedule 40 fittings be interchanged?
Do not assume interchangeability. Confirm the actual wall thickness, fitting dimensions, mating pipe schedule, welding requirements, and system specifications before installation.
Where can I find fitting dimensions?
