A puddle flange is a simple yet essential fitting used in civil construction to prevent water leakage where pipes pass through concrete structures. In RCC (Reinforced Cement Concrete) slabs, these flanges act as a seal that stops water from migrating along the outer surface of a pipe. Whether you are working on water tanks, basements, lift pits, or underground pipelines, installing a puddle flange correctly ensures waterproofing and structural durability. This step-by-step guide from Udhhyog , a leading supplier of GI, MS, and SS puddle flanges in India, explains how to use a puddle flange during RCC slab construction. 🧰 Step-by-Step Guide ✅ Step 1: Choose the Right Puddle Flange Select a puddle flange based on the pipe size and material (MS, GI, or SS). GI puddle flanges are ideal for general drainage and water pipes. Use stainless steel for corrosive environments or coastal zones. At Udhhyog , we provide puddle flanges in custom sizes with...

FAQs – Galvanized Pipe (Schema Optimized)
Q1. What is a galvanized pipe used for? Galvanized pipes are used for water lines, plumbing, fencing, structural applications, and rural infrastructure where rust resistance is needed.
Q2. Is GI pipe safe for drinking water? Yes, if zinc coating is intact. However, stainless steel is preferred in high-purity drinking systems.
Q3. What’s the difference between GI and MS pipe? GI pipe is MS pipe coated with zinc. GI resists corrosion better; MS is more economical for indoor and welded structures.
Q4. Which GI pipe class is best for underground use? Class C (Heavy) is best for underground or exposed use due to thicker coating and wall strength.
Q5. What is the life expectancy of galvanized pipes? Typically 30–50 years depending on water quality, climate, and coating thickness.
