How to Use a Puddle Flange in RCC Slab Construction – Step-by-Step Guide

-
  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. ๐Ÿงฐ 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...

Introduction to MS Pipes



Mild Steel (MS) Pipes are essential in modern construction, manufacturing, and infrastructure projects due to their durability, workability, and cost-effectiveness. From water pipelines to structural frames, MS pipes serve as the backbone of industrial development in India.

๐Ÿ“ Common Sizes of MS Pipes

MS pipes come in a variety of diameters and wall thicknesses, depending on the intended use. Below is a quick reference table:

Nominal Bore (NB)Outer Diameter (OD)Wall Thickness (mm)Common Use
15 mm (½ inch)21.3 mm2.0 – 2.6 mmPlumbing
25 mm (1 inch)33.4 mm2.6 – 3.2 mmWater pipeline
50 mm (2 inch)60.3 mm3.2 – 4.5 mmStructural use
100 mm (4 inch)114.3 mm4.5 – 6.0 mmIndustrial
200 mm (8 inch)219.1 mm6.0 – 8.0 mmHeavy-duty

Note: Custom lengths and square/rectangular options also available.

๐Ÿท️ Grades of MS Pipes in India

MS pipes are manufactured under Indian Standard codes, mainly:

๐Ÿ”น IS 1239 (Part 1) – Mild Steel Tubes for Water, Gas, and Air

  • Light, medium, and heavy class.

  • Suitable for plumbing and industrial distribution systems.

๐Ÿ”น IS 3589 – MS Pipes for Water & Sewage

  • Larger diameter.

  • Ideal for water transmission and structural work.

๐Ÿ”น IS 1161 – MS Pipes for Structural Use

  • Used in buildings, scaffolding, and fabrication.

  • Available in circular, square, and rectangular sections.

๐Ÿ”น Other International Equivalents

  • ASTM A53

  • BS 1387

  • EN 10255

๐Ÿญ Top Applications of MS Pipes

MS pipes are widely used across industries due to their strength and ease of welding and fabrication:

๐Ÿ”ง 1. Construction Industry

  • Roofing structures, beams, scaffolding.

  • Square and rectangular hollow sections are popular.

๐Ÿ’ง 2. Plumbing & Water Supply

  • Underground and overhead pipelines.

  • Corrosion-resistant when GI-coated.

๐Ÿ—️ 3. Fabrication & Structural Support

  • Steel furniture, staircases, and railings.

  • Frames for solar panel installations.

⚙️ 4. Industrial Equipment

  • Ducting and exhaust systems.

  • Conveyor systems and material handling.

๐Ÿ”‹ 5. Automotive & Railways

  • Chassis frames, trailer fabrication, etc.

๐Ÿ“ฆ Advantages of High-Quality MS Pipes

  • ✅ Easy to weld and fabricate.

  • ✅ High tensile strength.

  • ✅ Affordable compared to SS or alloy pipes.

  • ✅ Available in a wide range of sizes.

  • ✅ Recyclable and environment-friendly.

๐Ÿ›’ Tips for Choosing the Right MS Pipe

  1. Check Grade and IS Code Compliance

  2. Match Pipe Thickness with Application Needs

  3. Opt for ERW or Seamless Depending on Pressure Requirements

  4. Consider Galvanization for Outdoor Use

  5. Buy from Verified Udyog Suppliers

๐Ÿ“ Popular Udyog Locations for MS Pipe Supply

  • Mandi Gobindgarh, Punjab

  • Faridabad, Haryana

  • Raipur, Chhattisgarh

  • Howrah, West Bengal

  • Ahmedabad, Gujarat

These regions house major MS pipe manufacturers and distributors serving construction and infrastructure sectors.

❓ FAQs – High-Quality MS Pipes

๐Ÿ”น What is the full form of MS pipe?

MS Pipe stands for Mild Steel Pipe, made from low-carbon steel.

๐Ÿ”น Is MS pipe good for water lines?

Yes, especially when galvanized or coated to prevent rust.

๐Ÿ”น What is the difference between MS and GI pipe?

MS pipes are plain, while GI pipes are MS pipes with a galvanized zinc coating to resist corrosion.

๐Ÿ”น Can MS pipes be used for gas?

Yes, IS 1239 Grade B MS pipes are used for low-pressure gas lines.

๐Ÿ”น What is ERW MS pipe?

ERW (Electric Resistance Welded) MS pipes are formed by rolling and welding flat steel into a tube shape.
