Forged Barred Tee

High-Strength Piggable Branch Fitting

Forged Barred Tees are produced from forged material to achieve suitable mechanical strength and structural integrity. They are typically used for smaller pipe sizes and high-strength pipeline applications where forged construction provides superior material properties compared to fabricated alternatives.

Custom Barred Tee

Project-Specific Pigging Branch Connection

Custom Barred Tees are designed and manufactured according to project-specific engineering drawings and pigging system requirements. The bar configuration, pipe dimensions, wall thickness, material grade, and end connections can all be specified to meet the unique requirements of the pipeline and pigging program.

Design Data

Key Design Features of a Barred Tee

The internal bars are the defining feature of a Barred Tee. Their spacing and configuration must allow the intended pig to pass through the main line without entering the branch connection.

Important Design Considerations

Material Grades

Common Materials for Barred Tees

Material selection should be compatible with the parent pipeline, welding procedure, process fluid, operating pressure, and design temperature.

Standards & Compliance

Standards and Specifications

Barred Tees are frequently manufactured according to project-specific engineering requirements, with applicable pipeline and material standards governing their design and manufacture.

Project specifications and pigging system requirements are particularly important for barred tees because bar spacing, configuration, and fitting dimensions depend on the specific pig type and pipeline operating conditions.

Frequently Asked Questions

What is a Barred Tee used for?

A Barred Tee is used to create a branch connection on a piggable pipeline while preventing pipeline pigs from entering the branch line. It incorporates internal bars across the branch opening that deflect pigs back into the main pipeline run. This allows the pipeline to maintain its piggability for cleaning, inspection, and flow assurance operations while still accommodating branch connections for instruments, bypasses, or other pipeline systems.

What types of Barred Tees do you supply?

We supply straight barred tees, reducing barred tees, full encirclement barred tees, fabricated barred tees, forged barred tees, and custom barred tees in various materials, sizes, wall thicknesses, and configurations according to project and pigging system requirements.

How is the bar spacing of a Barred Tee determined?

The bar spacing of a Barred Tee is determined based on the type and dimensions of the pig used in the pipeline. The bars must be spaced close enough to prevent the pig body, cups, or discs from entering the branch opening, while remaining open enough to allow pipeline flow through the branch. The pig diameter, type, and operational requirements are provided to the manufacturer to design the correct bar configuration.

What materials are Barred Tees available in?

Barred Tees can be supplied in carbon steel, low-temperature carbon steel, high-strength carbon steel, alloy steel, stainless steel, and duplex steel. The material is selected to match the parent pipeline material, welding procedure, process fluid, operating pressure, and design temperature of the specific pipeline system.

What is the difference between a Fabricated and a Forged Barred Tee?

A Fabricated Barred Tee is manufactured by welding together pipe sections, plates, and bar components. This method is commonly used for large-diameter pipelines where forged fittings are not practical. A Forged Barred Tee is produced from a solid forged material block and is typically used for smaller pipe sizes where the forging process provides superior mechanical properties and a more homogeneous material structure.

Can you supply custom Barred Tees according to project drawings?

Yes. We supply custom fabricated barred tees manufactured according to approved engineering drawings and project-specific requirements. These can be designed for specific main pipe sizes, branch sizes, wall thicknesses, bar configurations, material grades, and end connection types. Material Test Certificates, dimensional inspection, NDT reports, and third-party inspection can be provided as required.
