About this product

Product information from the supplier.

Our high-performance welded tees are precision-engineered industrial pipe fittings manufactured through advanced integral forging or casting processes. Designed to provide exceptional structural integrity and optimal sealing, these components are critical for minimizing flow resistance and ensuring maximum stability within complex piping networks, making them indispensable for modern industrial infrastructure.

Engineered for versatility and resilience, our tees are available in premium carbon steel, stainless steel, and specialized alloy steels. Utilizing robust butt-welding connections, they create seamless integration between main and branch lines, eliminating leak points and ensuring safe operation in extreme environments ranging from -196℃ to over 600℃, across petrochemical, power, and gas sectors.

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.
