The Industrial-Grade Stainless Steel BW (Butt-Weld) Red Tee is a heavy-duty pipe fitting designed to create branch connections in high-pressure pipelines, allowing fluid to flow from the main line to a smaller branch. Constructed from seamless 304 or 316 stainless steel, this reducing tee features butt-weld ends and a reinforced branch, making it ideal for demanding industrial applications requiring structural integrity and flow efficiency.
Reinforced Branch Design:
Thicker wall at the branch connection (1.5x main pipe wall) withstands high-pressure loads, reducing stress concentration by 25% compared to standard tees.
Smooth internal radius (1.0x pipe wall thickness) at the branch junction minimizes turbulence and pressure loss in multi-line systems.
Premium Material & Construction:
Seamless ASTM A312 stainless steel (304/316) with a minimum yield strength of 205 MPa, rated for working pressures up to 3,000 PSI (316 stainless steel, schedule 160).
Heat-treated to eliminate welding stresses, ensuring dimensional stability in high-temperature environments (up to 800°C with metal-to-metal seals).
Installation Compliance:
Butt-weld ends (37.5° bevel) meet ANSI B16.9 and ASME B31.3 standards, compatible with automatic welding machines for large-scale pipeline projects.
Available in equal tee (all branches same size) and reducing tee (branch smaller than main line) configurations, sizes ranging from 1" to 24" NPS.
Corrosion Resistance:
316 stainless steel variant with 3.5% molybdenum resists pitting in aggressive media like sulfuric acid and sodium hydroxide, with a passivated surface for enhanced durability.
Ideal for industrial pipeline branching in high-pressure systems:
Oil & Gas Refineries: Branching from main process lines to control valves and instrument connections, compliant with API 6A for wellhead equipment.
Power Generation: Creating connections from steam headers to turbines and generators in thermal plants, with 304 stainless steel resisting oxidation at 550°C.
Chemical Plants: Distributing raw materials from storage tanks to reactors, with 316 stainless steel meeting CEPDG standards for corrosive chemical handling.
Water Treatment: Branching from main water mains to filtration units and pumps, enduring chlorinated water and abrasive particulates in municipal systems.
Q: What is the difference between a red tee and an equal tee?
A: A red tee has a smaller branch diameter than the main line, while an equal tee has all branches the same size, suitable for balanced flow distribution.
Q: Can this tee be used for high-velocity gas flows?
A: Yes, the reinforced branch design withstands gas velocities up to Mach 0.3, but install a flow straightener upstream for optimal performance.
Q: How to inspect for weld defects in the branch junction?
A: Use ultrasonic testing (UT) or magnetic particle inspection (MPI) to detect subsurface flaws, especially in critical pressure systems.
Q: Are there fire-safe designs for flammable media?
A: While the tee itself is fire-resistant, pair with fire-safe gaskets and valves for complete system compliance with API 607.
