Forming the Tee (hot pressing or mechanical extrusion)
Threading or Machining Ends (CNC precision)
Cleaning & Pickling
Hot-dip Galvanizing (immersed in molten zinc, EN ISO 1461 certified)
Cooling & Straightening
Quality Inspection (Thickness, adhesion, leakage, pressure testing per ISO/ANSI/BS standards)
Packing & Logistics

High Quality Galvanized Steel Pipe Tee for Durable Connections

Key Material & Machining Highlights

Material: Carbon steel pipe, hot-dip galvanized (Zn coating ≥ 70µm) per EN 10240/ISO 1461.
Machining: CNC for precise threads, smooth flow path, accurate geometry.
Coating: Full zinc coverage, strong bond (tests: hammer, adhesion, salt spray per ASTM B117).
Inspection: 100% hydraulic pressure test; key nodes verified by ultrasonic and visual checks.

Distinct Technical Advantages of Galvanized Steel Pipe Tee

Anti-corrosion: Hot-dip galvanizing delivers superior corrosion resistance in aggressive media, extending system life over uncoated fittings.
Leak Prevention: CNC-machined threads and socket ends ensure tight, vibration-resistant seals. Zero-leak statistics in tests across 500+ fittings (ISO 9001:2015).
Strength & Fatigue: Enhanced mechanical performance (≥ 350 MPa tensile strength), sustains high-cycle pressure fluctuations (e.g., fire sprinkler mains, oil lines).
Standardized Interface: Available in BSP, NPT, and custom threads for global compliance. Certified per ISO 49, ANSI B16.11.
Cost-Effectiveness: Lower total cost of ownership compared to stainless steel—typical ROI in 1.5-2 years for waterworks and fluid transfer lines.
Adaptability: Suitable for aggressive, contaminated, or drinking water with minimal risk of leaching (meets FDA/NSF 61 for potable systems).

Product FAQs: Technical & Industry Insights

Q1: What is the base material and zinc coating standard for galvanized steel pipe tee?

A: It is typically made from carbon steel grades like Q235B, ASTM A106 or A53, with hot-dip galvanizing to EN 10240/ISO 1461 (minimum zinc coating 70µm, average 85–100µm for Y&L).

Q2: What are common connection types and what installation standards apply?

A: BSP (ISO 228), NPT (ANSI/ASME B1.20.1), and socket weld ends. Install to ANSI B16.3/ISO 49 guidelines using appropriate thread sealants for system pressure safety.

Q3: How does hot-dip galvanizing enhance corrosion resistance?

A: The zinc coat forms a sacrificial barrier, resisting oxidation and rust. Salt spray testing (ASTM B117) routinely proves >600 hours durability.

Q4: Can galvanized steel pipe tee be used for drinking water?

A: Yes, if zinc purity is high and internal passivation is applied, they conform to NSF 61 and EU 98/83/EC standards.

Q5: What pressure and temperature is standard for these tees?

A: Standard tees are rated for up to 25 bar and temperature range of -20°C to +180°C, depending on wall thickness and connection.

Q6: How do you ensure full penetration of zinc inside threaded areas?

A: After machining, finished tees undergo 360° immersion; re-tapping and sealant application ensure all threads are fully protected.

Q7: Are there certifications offered for traceability and compliance?

A: Every batch comes with ISO/EN compliance certificates, 3.1 MTC (Material Test Certificate), and third-party SGS/TÜV reports on request.
