Hot Dip Galvanized Puddle Flange – Rust-Proof Concrete Pipe Seal
Hot Dip Galvanized Puddle Flange – Rust-Proof Concrete Pipe Seal
If you're installing pipes through concrete walls or floors, especially in underground structures, a hot dip galvanized puddle flange is your best defense against corrosion and water seepage. It combines the strength of mild steel with the long-term protection of zinc coating, offering a durable and rust-proof sealing solution.
In this article, we’ll cover its benefits, applications, manufacturing process, and where to buy hot dip puddle flanges in Delhi and India.
Why Choose Hot Dip Galvanized Puddle Flange?
- ✅ Rust-proof protection in wet or corrosive environments
- ✅ Ideal for underground or submerged concrete installations
- ✅ 40–80 microns of zinc coating ensures long-lasting life
- ✅ Available in custom and standard sizes (50 mm to 600 mm)
The zinc coating bonds metallurgically to the steel, forming a barrier that resists moisture, chemicals, and atmospheric corrosion for decades.
Perfect for Underground Pipeline Waterproofing
Whether it's a water tank, drainage shaft, STP line, or cable duct, the hot dip galvanized puddle flange ensures a leak-proof interface between the concrete and the pipe. It prevents water migration around the pipe’s outer surface, safeguarding structural integrity.
Used by builders, infrastructure companies, and civil engineers, these flanges are standard in:
- Water tanks and rainwater harvesting pits
- Underground cable trenches
- Basement drainage and manholes
- Chemical containment zones
How Hot Dip Galvanized Puddle Flanges Are Made
- Mild Steel Cutting: MS rings/flanges are laser-cut or punched to specification.
- Welding: Puddle flange collar is welded to pipe stub.
- Surface Cleaning: Degreased, pickled, and fluxed to prep the surface.
- Galvanizing: Dipped in molten zinc (~450°C) for uniform coating.
- Inspection & Dispatch: Thickness tested and packed for delivery.
All products are checked for zinc layer consistency and coating adhesion.
