Available in both seamless and welded butt-weld configurations across complete schedule wall thicknesses, these precision-engineered fittings deliver exceptional mechanical strength and long-term corrosion resistance for chemical processing, oil and gas, water treatment, and heavy industrial piping networks worldwide.
What is stainless steel tee?
The stainless steel equal tee is a high-quality ASME B16.9 stainless steel pipe fitting designed to efficiently distribute fluid or gas flow across three branches in piping systems. With all three outlets of equal size, this stainless steel equal tee ensures balanced flow distribution, making it ideal for systems requiring precise fluid direction and flow rate control. Manufactured from premium stainless steel, our stainless steel equal tees offer excellent corrosion resistance, strength, and durability, ensuring long-lasting performance in even the most demanding environments.
Our equal tees are produced in compliance with international standards such as ASME, ASTM, JIS, and DIN, making them suitable for a wide range of industrial applications, including oil and gas, chemical processing, and water treatment.

FAQs
1. What manufacturing processes do you use for seamless and welded stainless steel equal tees?
We produce seamless equal tees up to standard sizes using hydraulic bulging or hot extrusion processes to maintain consistent wall thickness across the run and branch. For larger industrial diameters, equal tees are manufactured by press-forming stainless steel plate followed by 100% full-penetration longitudinal seam welding, fully tested to meet ANSI/ASME B16.9 specifications.
2. How do you ensure branch alignment, wall thickness, and material integrity during QC?
Every production batch undergoes 100% Positive Material Identification (PMI) chemical testing and full solution annealing to restore corrosion resistance. Our quality team checks 90-degree branch squareness, center-to-end dimensions, and ultrasonic wall thickness across all three outlets. All shipments include full EN 10204 3.1 Material Test Reports (MTRs) and support Third-Party Inspection (TPI) by agencies such as SGS, BV, or TÜV.
3. What are your minimum order quantities (MOQ) and production lead times for export orders?
Standard manufacturing lead time is 30 to 45 days upon order confirmation and drawing approval. We offer flexible MOQs for standard 304/304L and 316/316L material grades, allowing international buyers to combine equal tees, reducing tees, elbows, and flanges in a single container order to optimize freight costs.
4. How are equal tees packaged to prevent branch edge damage and corrosion during sea transit?
All three beveled ends are fitted with protective plastic end caps to prevent edge chipping or denting. Smaller to medium-sized equal tees are packed inside ISPM-15 heat-treated, seaworthy wooden cases lined with waterproof plastic barriers. Large-diameter tees are securely steel-strapped into heavy-duty wooden crates or onto pallets with protective inter-layer cushioning.
5. What commercial delivery terms and international shipping options do you support?
We accommodate standard international commercial trade terms, including EXW, FOB (Taiwan/China ports), CFR, CIF, and DDP. Ocean freight can be arranged as Full Container Load (FCL) or Less than Container Load (LCL). For urgent plant shutdown projects or prototype testing, express air freight shipping is also available.
