The High-Purity Stainless Steel BSPT (British Standard Pipe Taper) Thread Class 150 Y-Type Tee is a precision pipe fitting designed for reliable branch connections in high-purity and corrosive fluid systems. Constructed from 304L or 316L stainless steel, this tee features BSPT threads (ISO 7-1 compliant) and a Y-shaped design, ensuring smooth flow transition and minimal turbulence in process piping.
High-Purity Material & Finish:
304L (low carbon) or 316L (extra low carbon) stainless steel, with a passivated surface (Ra ≤0.8μm) to reduce metal ion leaching, critical for ultra-pure water and pharmaceutical applications.
Seamless construction (no welds) minimizes particle entrapment, meeting 3-A Sanitary Standards and FDA 21 CFR Part 177 for direct food contact.
Precision Threading & Design:
BSPT threads (55° taper) compliant with ISO 7-1, providing leak-tight connections without additional sealants, compatible with metric pipes and fittings (e.g., DIN, BS EN).
Y-type geometry (60° branch angle) reduces flow resistance by 15% compared to traditional tees, with a reinforced branch connection (1.5x wall thickness) for pressure surges.
Corrosion & Pressure Resistance:
Rated for Class 150 (300 PSI at 20°C), with 316L stainless steel offering superior resistance to intergranular corrosion in welded systems without post-weld annealing.
Temperature range: -250°C to 450°C (316L), suitable for cryogenic ethanol lines and hot water sanitization systems.
Compliance & Certification:
Meet EN 10226-1, NSF/ANSI 61, and USP Class VI standards, with material traceability reports and mill certificates available for critical applications.
Optional electropolishing (Ra ≤0.4μm) for semiconductor-grade purity, ideal for ultra-pure water (UPW) and chemical mechanical planarization (CMP) processes.
Perfect for high-purity and corrosive fluid distribution:
Pharmaceutical Manufacturing: Branch connections in purified water (PW) and water-for-injection (WFI) systems, compliant with cGMP and EU GMP guidelines.
Semiconductor Fabrication: Chemical delivery lines for photoresist and etching agents, with 316L stainless steel preventing particle contamination in cleanroom environments.
Food & Beverage: Beverage blending systems and dairy pasteurization lines, ensuring no product residue buildup in the Y-branch junction.
Biotech Research: Laboratory fluid transfer lines for cell culture media and reagents, with BSPT threads compatible with European equipment standards.
Q: What is the difference between BSPT and NPT threads?
A: BSPT (55°) is commonly used in Europe, while NPT (60°) is standard in North America. Use a BSPT-to-NPT adapter for cross-standard compatibility.
Q: Can this tee be used with plastic pipes?
A: Yes, compatible with PVC, PP, and PEX pipes via BSPT-to-plastic adapters, but avoid high-pressure applications with rigid plastic pipes.
Q: How to clean the tee for high-purity applications?
A: Use deionized water flushing or steam-in-place (SIP) at 121°C for 30 minutes; avoid abrasive cleaners that may damage the passivated surface.
Q: What is the maximum working pressure for 316L stainless steel?
A: 300 PSI at 20°C (Class 150); higher pressure ratings (Class 300/600) are available with thicker wall schedules (schedule 80/160).
