Stainless Steel Butt Weld Elbows
A stainless butt-weld elbow is a welded AISI 304 or 316 elbow made with the same outside diameter as the pipe, turning a stainless pipeline by 90 degrees.
It is used at turns of pipe routes in food, dairy and beverage plants, CIP lines and chemical processes. 12 sizes from 21.3 mm to 219.1 mm are available, plus 154 mm, 355 mm and a Ø60 mm option in grade 316.
Main Applications
- Food and dairy process lines
- CIP and cleaning lines
- Pharmaceutical and cosmetics plants
- Chemical and treatment lines
- Seawater lines
- Stainless manifold fabrication

Material Options
| Part | AISI 304 stainless | AISI 316 stainless | Carbon steel |
|---|---|---|---|
| Body | AISI 304 stainless steel | AISI 316 stainless steel (selected sizes) | Carbon steel, grade depending on model |
| Surface | Uncoated stainless | Uncoated stainless | Black or oiled |
| Wall thickness | Depending on model | Depending on model | Standard, SCH40, SCH80 |
| Welding | TIG / stainless electrode | TIG / stainless electrode | Stick or TIG/MIG |
| Suitable media | Food, drinking water, mild chemicals | Chloride-containing water, seawater, aggressive chemicals | Heating water, steam, fire water |
Which material? AISI 304 elbows are sufficient for food and general process turns; AISI 316 is preferred for chloride-containing water and aggressive chemicals, and the elbow grade must match the pipe.

Send the elbow outside diameter, grade and quantity; we will confirm the suitable stainless elbow from stock.
How to Choose?
- Measure the outside diameterDetermine the stainless pipe outside diameter in mm.
- Match the gradeIf the pipe is 316, the elbow must be 316 too.
- Check the wall thicknessConfirm compatibility with the pipe wall.
- Plan the weldProtect the inner surface with backing gas during TIG welding.
