Cladding of Large-Diameter Pipeline Tee | Weld Overlay Solutions by FNS
Cladding of large-diameter pipeline tee plays a critical role in protecting key junctions within pipeline systems that operate in aggressive environments. At FNS Pipeline, we recently completed a large diameter tee cladding project using automated weld overlay technology. This process deposits a dense, uniform corrosion-resistant alloy inside the fitting, significantly enhancing its resistance to chemical attack, erosion, and high-temperature degradation.
Our customized large diameter tee overlay solution provides extended service life and reduces maintenance costs, especially in high-demand industries such as oil & gas, petrochemical, and thermal power generation.

Why Large Diameter Tee Cladding Is Essential?
A cladded pipe tee ensures the inner surface of the component can withstand the harshest media, including sour gas, seawater, or corrosive slurries. Without internal protection, pipeline tees are highly susceptible to localized corrosion, especially at weld junctions or flow disturbance zones.
Our weld overlay method ensures:
- Strong metallurgical bonding between the overlay and base metal
- Minimal dilution and controlled chemistry
- Uniform thickness with full internal coverage
Project Highlights
- Component: Tee fitting with diameter >600mm
- Overlay Alloy: Inconel 625 (nickel-based corrosion-resistant alloy)
- Method: Automated GTAW overlay
- Overlay Thickness: 2.5–3.0 mm
- Applications: Sour service, chlorinated fluid lines, high-pressure steam systems
Quality & Inspection
Every cladded pipe tee from FNS Pipeline undergoes comprehensive quality control, including:
- Pre-weld surface preparation and parameter validation
- Real-time weld monitoring
- Non-destructive testing (UT, PT, RT)
- Post-weld chemical composition analysis
- Dimensional verification per engineering drawings
