Engineered to deliver reliable flow distribution in high-pressure piping systems, the Stainless Steel Seamless TEE ASTM A403 WP304 is a critical component for industrial and commercial applications. Constructed from 304 stainless steel, this tee adheres to the stringent requirements of ASTM A403, ensuring consistent material quality and mechanical performance. The seamless design eliminates weld-related weaknesses, providing a uniform structure that withstands extreme pressures and temperatures while minimizing leak risks. With precise dimensional accuracy and a smooth internal surface, it facilitates efficient fluid flow and reduces pressure loss, making it an essential part of modern piping networks.
Robust Pressure Resistance: Capable of withstanding working pressures up to 17,500 PSI (depending on size and wall thickness), this tee is suitable for demanding applications such as oil refineries, chemical plants, and power generation facilities.
Corrosion-Resistant Alloy: The 304 stainless steel composition (18Cr-8Ni) offers excellent resistance to oxidation, scaling, and general corrosion in environments ranging from freshwater to mild acids. It is widely used in water treatment, food processing, and pharmaceutical industries where material purity is non-negotiable.
Versatile Sizing Options: Available in nominal bore sizes from 1/8" NB to 48" NB, with wall thicknesses conforming to SCH 5S, SCH 10S, up to SCH XXS. Ends can be supplied as butt-weld (for high-pressure systems) or threaded (for low-pressure applications), ensuring compatibility with various piping systems.
Stringent Quality Assurance: Each tee undergoes hydrostatic testing, ultrasonic inspection, and chemical analysis to verify compliance with ASTM A403/ASME SA403 standards. This rigorous testing ensures freedom from defects and consistent performance across all installations.
Oil & Gas Sector: Used in upstream and downstream pipelines to divert flow in refineries, petrochemical plants, and offshore platforms, resisting harsh hydrocarbons and corrosive byproducts.
Power Generation: Installed in steam and condensate lines of thermal power plants, where it withstands high temperatures and cyclic loading.
Water & Wastewater Treatment: Suitable for potable water distribution, sewage systems, and industrial effluent lines, resisting chlorination and biological corrosion.
HVAC Systems: Facilitates efficient fluid distribution in heating and cooling networks, ensuring minimal pressure drop and long service life.
Q: What is the temperature range for WP304 tees?
A: The tee operates efficiently from -200°C to 870°C in intermittent service. For continuous high-temperature use (above 425°C), consider stress-relief annealing to maintain corrosion resistance.
Q: Can I use this tee with non-stainless steel pipes?
A: Yes, but avoid galvanic corrosion by using dielectric unions or isolating gaskets when connecting to carbon steel or other dissimilar metals.
Q: How do I inspect for material defects?
A: Non-destructive testing methods like radiographic (RT) or magnetic particle inspection (MPI) are recommended for critical applications. Detailed test reports are available for each batch.
Q: What filler material should I use for welding?
A: Use 308L or 347 filler rods for TIG/MIG welding to match the chemical composition and ensure corrosion resistance. Preheating is generally unnecessary for thin walls but may be required for thick sections.
