Need a dependable fitting? Buttweld Reducing Tee on MetalMitra comes in seamless, welded and fabricated to ASME B16.9, ready for changes in direction, branching and size transitions.
Through MetalMitra you can source Buttweld Reducing Tee in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.
A reducing tee has a branch smaller than the run, allowing a smaller line to be taken off a main header at 90°.
Buttweld fittings are bevelled at the ends and welded directly to the pipe, giving a continuous, leak-resistant joint with a smooth bore and low pressure drop. They are the standard choice for process piping above 2" NB and for high-pressure, high-temperature service.
Available forms & variants
- Elbows — 45°, 90° and 180° long and short radius elbows.
- Tees & Crosses — Equal and reducing tees and crosses.
- Reducers — Concentric and eccentric reducers.
- Stub Ends & Caps — Lap joint stub ends and pipe end caps.
Performance highlights
- Smaller Branch — Branch reduced from the run size.
- Header Take-Offs — Used for branch lines from main headers.
- Smooth Flow — Butt-welded joints for a smooth bore and minimal pressure drop.
- High-Pressure Ready — Rated for high-pressure, high-temperature service.
