Buy Butt Weld Fittings Online in Australia
Butt weld fittings join pipe by welding the fitting to the pipe end, giving a continuous, smooth bore joint for process and service piping. AIMS Industrial supplies AAP butt weld elbows, tees, reducers and caps in carbon steel and in 304/304L and 316/316L stainless steel, in sizes from 1/2 inch to 6 inch across the range.
What's in the range
| Fitting | What the range includes |
|---|---|
| Elbows | 90 degree long radius and short radius elbows, 45 degree long radius elbows and 180 degree long radius elbows in carbon steel. Stainless 90 degree elbows in 304/304L and 316/316L, and 316/316L 45 degree elbows. |
| Tees | Equal tees in carbon steel and in 304/304L and 316/316L stainless, plus carbon steel reducing tees. |
| Reducers | Concentric reducers in carbon steel and 316/316L stainless, and eccentric reducers in carbon steel. |
| Caps | Carbon steel caps and 316/316L stainless caps. |
Carbon steel fittings are listed in three wall classes: Std (standard), X-Stg (extra strong) and SGP. Stainless fittings are listed in Sch 10S and Sch 40S wall thickness. Sizes are shown on each listing.
Choosing butt weld fittings
Match the fitting to the pipe: same material, same nominal size and same wall thickness or schedule, so the bores line up at the weld. Use a long radius elbow where you have the space, because it gives smoother flow and less pressure drop, and a short radius elbow where space is tight. Concentric reducers keep the pipe centre line in line, and eccentric reducers keep the top or bottom flat, which helps with drainage and pump suction. Choose 316/316L for harsher or corrosive environments and 304/304L for general stainless use.
Always check the data sheet. Confirm the material grade, wall thickness, size and any required certification against your pipe and specification before ordering, and have welding done by a qualified welder to the procedure that applies to your job.

Butt weld fittings FAQs
What is a butt weld fitting?
A butt weld fitting has bevelled ends that are welded directly to the end of a pipe, giving a continuous joint with a smooth bore. Elbows, tees, reducers and caps are the common shapes.
What is the difference between a long radius and a short radius elbow?
A long radius elbow has a larger bend radius, which gives smoother flow and less pressure drop. A short radius elbow has a tighter bend and suits limited space.
What is the difference between a concentric and an eccentric reducer?
A concentric reducer is symmetrical, so the pipe centre lines stay in line. An eccentric reducer is offset so one side stays flat, which helps with draining and pump suction lines.
What do Std, X-Stg and SGP mean?
They are the wall classes listed for the carbon steel fittings. Std is standard wall and X-Stg is extra strong, which has a thicker wall. Check each listing, or call us, to match the class to your pipe.
What do Sch 10S and Sch 40S mean?
They are the pipe wall schedules listed for the stainless fittings. Sch 40S has a thicker wall than Sch 10S. Match the schedule to your pipe.
Do you have flanges to go with these fittings?
