The Heavy-Duty Stainless Steel BW (Butt-Weld) Equal Tee is a robust pipe fitting designed to create three-way connections in high-pressure, high-temperature industrial pipelines. Constructed from seamless 304 or 316 stainless steel, this equal tee features butt-weld ends and uniform branch sizes, ensuring balanced flow distribution and structural integrity in demanding applications.
Uniform Flow Design:
Equal branch diameters (e.g., 4" x 4" x 4") ensure symmetrical flow division, reducing turbulence by 25% compared to reducing tees, ideal for multi-line systems requiring balanced pressure.
Smooth internal surface (Ra ≤1.6μm) and 90° branch angle promote laminar flow, minimizing pressure loss in high-flow environments.
Premium Seamless Construction:
Extruded from a single billet of ASTM A312 stainless steel (304/316), with a minimum tensile strength of 515 MPa and yield strength of 250 MPa.
Rated for working pressures up to 2,500 PSI (316 stainless steel, schedule 80) and temperatures from -46°C to 815°C, suitable for steam, oil, and gas applications.
Precision Welding Compliance:
Butt-weld ends with 37.5° bevel meet ANSI B16.9 and ASME B31.1 standards, enabling full-penetration welds for schedule 40/80 pipes in power and process piping.
Available in sizes 1" to 36" NPS, with custom wall thicknesses for nuclear-grade applications (ASME BPVC Section III).
Corrosion Resistance:
316 stainless steel variant with molybdenum alloying resists pitting in chloride-rich media, while 304 is suitable for non-corrosive environments like compressed air systems.
Ideal for balanced flow distribution in industrial pipelines:
Oil & Gas Processing: Creating three-way connections in separator systems and heat exchanger networks, compliant with NACE MR0175 for sour gas service.
Power Generation: Distributing steam from headers to turbines and auxiliary equipment in thermal plants, with 304 stainless steel resisting oxidation at 550°C.
Chemical Processing: Dividing flow in reactor feed lines and mixing systems, with 316 stainless steel meeting cGMP standards for pharmaceutical manufacturing.
Water Treatment: Distributing water from main mains to multiple filtration units in municipal plants, enduring chlorinated water and high-pressure surges.
Q: Can equal tees be used for reducing flow?
A: No, equal tees are for balanced flow; use reducing tees when branch diameter differs from the main line.
Q: What is the recommended support spacing for large-diameter tees?
A: Install supports within 1.5x pipe diameter of the tee to minimize stress on the branch junctions, especially in horizontal runs.
Q: How to prevent weld decay in 304 stainless steel tees?
A: Use 304L (low carbon) for welded applications to avoid intergranular corrosion, or apply post-weld heat treatment for thick sections.
Q: Are there fire-resistant coatings available?
A: Yes, intumescent coatings (ASTM E119 compliant) can be applied, providing 2-hour fire resistance for critical pipeline connections.
