Our pipe tees are high-strength components used to combine or divide fluid flow within a piping network. Designed with a 90-degree branch, we offer both Equal Tees (where the branch diameter matches the main pipe) and Reducing Tees (where the branch is smaller), ensuring maximum flexibility for complex piping layouts.

Primary Applications
Pipe tees are indispensable in industrial systems where multi-directional flow is required:
Oil & Gas Pipelines: Creating branch connections for gathering lines and distribution manifolds.
Petrochemical & Refining: Handling the diversion of chemicals and hydrocarbons under high pressure and temperature.
Power Generation: Used in cooling water systems and steam distribution networks.
HVAC & Civil Construction: Managing flow in large-scale heating, cooling, and fire protection systems.
Mining & Slurry Transport: Specifically designed heavy-wall tees are used to handle abrasive materials.
Quality Assurance & Inspection
To ensure the integrity of the branch weld and the overall structural strength, all our tees undergo:
Dimensional Verification: Ensuring 90-degree accuracy and precise beveling for easy field welding.
Non-Destructive Testing (NDT): Including Ultrasonic (UT), Magnetic Particle (MPI), and X-ray testing on welded joints.
Surface Treatment: Provided with rust-proof oil, black painting, hot-dip galvanizing, or sandblasting as per client requirements.
Certification: Every shipment includes a Mill Test Certificate (MTC) per EN 10204 3.1, documenting the chemical and mechanical properties of the steel.
