Through MetalMitra you can source 180 Degree Return Bend in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.
A 180° return bend reverses the flow direction and is widely used in heat exchanger coils, furnace tubes and serpentine piping.
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.
What you can source
- 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.
Key properties
- Full Reversal — Turns the flow back parallel to the original run.
- Coil Applications — Used in heaters, coolers and heat exchangers.
- Smooth Flow — Butt-welded joints for a smooth bore and minimal pressure drop.
- High-Pressure Ready — Rated for high-pressure, high-temperature service.
