Need a dependable branch outlet? Weldolet on MetalMitra comes in all major branch sizes and ratings to MSS SP-97, ready for reinforced branch connections on run pipe.
Through MetalMitra you can source Weldolet in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, across a broad range of sizes and pressure ratings.
A weldolet is a buttweld branch outlet welded onto the run pipe; its bevelled outlet is butt-welded to the branch pipe for a full-flow, reinforced branch connection.
Olets are forged branch outlet fittings welded onto the run pipe to create a reinforced branch connection. They are a compact, cost-effective alternative to reducing tees and allow branches to be added at any position along the run pipe.
Available forms & variants
- Weldolet — Buttweld branch outlet for full-flow branches.
- Sockolet & Threadolet — Socket weld and threaded outlets for small-bore branches.
- Elbolet & Latrolet — Outlets for elbows and 45° lateral branches.
- Nipolet, Sweepolet & Flangeolet — Integral nipple, contoured and flanged outlets.
Performance highlights
- Buttweld Outlet — Full-flow branch connection.
- Reinforced — Reduces stress at the branch.
- Integral Reinforcement — Designed to reinforce the run pipe at the branch.
- Cost Saving — Lighter and cheaper than a full reducing tee.
