About this product

Product information from the supplier.

Welded tees are high-performance industrial pipe fittings engineered through precision integral forging or casting processes. Designed for critical structural strength and optimal sealing, these components minimize flow resistance and ensure maximum stability in complex piping networks. They are available in a diverse range of premium materials, including carbon steel (A234 WPB/A420 WPL6), stainless steel (A403 WP304/316L), and specialized alloy steels (A234 WP11/WP22/WP91), making them ideal for transporting water, steam, oil, and corrosive fluids under extreme conditions.

Utilizing a robust butt-welding connection method, welded tees create a seamless integration between the main pipeline and branch lines. This eliminates potential leak points and enhances the overall system integrity. Whether deployed in high-pressure petrochemical plants, thermal power stations, or long-distance gas pipelines, our welded tees are manufactured to meet the rigorous demands of modern industrial infrastructure, ensuring safety and efficiency across a wide temperature spectrum from -196℃ to over 600℃.

Frequently Asked Questions

Q: What is the difference between an Equal Tee and a Reducing Tee?

An Equal Tee has a branch diameter identical to the main run, maintaining constant flow volume. A Reducing Tee has a smaller branch diameter, used to feed auxiliary equipment or manipulate system pressure differentials.

Q: When should I choose a Barred Welded Tee (Scraper Tee)?

Barred tees are essential in pipelines requiring routine PIG (Pipeline Inspection Gauge) or scraper operations. The internal bars prevent the cleaning tool from entering the branch line.

Q: Which material is best for highly corrosive chemical pipelines?

For corrosive environments, Stainless Steel (such as A403 WP304L or WP316L) is highly recommended due to its superior oxidation and corrosion resistance.

Q: Does the welded tee comply with ASME B16.9 standards?

Yes, all our welded tees are manufactured in strict accordance with ASME B16.9 for factory-made wrought steel butt-welding fittings, ensuring global industry compatibility.

Q: What are the temperature limitations for Carbon Steel welded tees?

Carbon steel welded tees typically operate within a temperature range of -29℃ to 425℃. For more extreme temperatures, stainless or alloy steels should be selected.

Q: What NDT tests are performed to ensure the quality of the tees?

We employ a comprehensive testing suite including Ultrasonic Testing (UT), Radiographic Testing (RT), Hydrostatic pressure tests, and precise dimensional inspections.
