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...

Looking for the accurate GI pipe weight chart to estimate load, transportation cost, or bulk purchase weight? This guide gives you the complete weight chart of GI (Galvanized Iron) Pipes for B Class and C Class, in mm and inches, as per IS:1239 standards — ideal for civil projects, plumbing, and industrial Udyog planning.
✅ Quick Answer:
GI pipe weight per meter depends on the nominal bore (NB) size, wall thickness (B or C Class), and standard length. C Class pipes are thicker and heavier than B Class, suitable for high-pressure and structural Udyog applications.
