Description
Stainless Steel Weld 45° Elbow
Stainless Steel Weld 45° Elbows are designed to provide a smooth 45-degree directional change in stainless steel piping systems. Compatible with Schedule 10 and Schedule 40 pipe, these butt weld fittings provide corrosion resistance, dimensional consistency, and dependable performance in commercial and industrial applications.
Manufactured from premium stainless steel materials and produced to recognized ASTM, ASME, ANSI, and MSS standards, these elbows are well suited for process piping, food and beverage, chemical processing, water treatment, and other demanding service environments.

45° Directional Change
The 45° elbow design provides a gradual change in piping direction without creating the sharper turn of a 90° elbow. This makes it useful where the piping layout requires a moderate directional offset or where a smoother flow transition is preferred.
The internal geometry is designed to support efficient fluid movement while helping minimize unnecessary turbulence and pressure loss.
Butt Weld Connection
These elbows use butt weld ends for permanent installation in compatible stainless steel piping systems. Precision-formed ends support accurate fit-up before welding and help create a continuous welded connection between the fitting and adjoining pipe.
Confirm pipe size, schedule, material requirements, and welding procedures before fabrication or installation.

Frequently Asked Questions
What is a 45° butt weld elbow?
A 45° butt weld elbow changes the direction of a piping system by 45 degrees and is welded directly to compatible pipe.
What schedules are available?
The supplied product information lists Schedule 10 and Schedule 40 compatibility.
What connection type is used?
These fittings use butt weld connections for permanent installation in compatible stainless steel piping systems.
What material standard applies to the raw material?
The raw stainless steel material conforms to ASTM A312.
What manufacturing and testing standards apply?
The fittings are manufactured and tested in accordance with ASTM A403 and ASME SA403/SA403M.
What dimensional standards apply?
Applicable wall thicknesses and dimensions conform to ANSI B16.9, ANSI B16.28, and MSS SP-43.
Why use a 45° elbow instead of a 90° elbow?
A 45° elbow provides a more gradual directional change and can be useful where a smaller offset or smoother flow transition is required.
Can Schedule 10 and Schedule 40 fittings be interchanged?
Do not assume interchangeability. Confirm actual wall thickness, mating pipe schedule, fitting dimensions, and welding requirements before installation.
Where can I find fitting dimensions?
