About

Duplex Steel Barred Tee

Product overview combined with Duplex Steel material context for project selection.

A barred tee (pigged tee) is a tee or any fitting with a branch used in pipelines that is pigged and has a restriction bar welded internally preventing the pig from traveling down a branch connection. The bars are installed so they are flush with the inside diameter of the pipeline to keep the pig from hanging up when it passes through. The bars should be of a similar or identical material as the parent material.

Available in numerous sizes and allied specifications to meet several needs of clients, Barred Reducing Tee Pipe Fittings can be customized too. It has features like High Strength, High Toughness, Corrosion Resistant, and Deformability. Our respected clients can purchase these fittings from us in a confine time frame on several specifications.

Manufacturing note
