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. 🧰 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...

🛠️ Gate Valve vs Globe Valve: Comparison for Industrial Buyers

-


 High-pressure valves are essential in systems where fluid or steam is transported under intense pressure, such as boilers and hydraulic lines. They are designed to withstand extreme temperature and pressure levels, ensuring safety, efficiency, and system control.


High-pressure valves are used in boilers to manage steam pressure and prevent explosions, while in hydraulic lines, they regulate fluid pressure and flow. These valves must resist corrosion, heat, and pressure to ensure safety in industrial-grade systems like refineries, power plants, and heavy machinery.



🔥 Applications in Boilers

Valve TypeFunction in Boilers
Safety ValveReleases excess steam to prevent overpressure
Globe ValveControls and throttles steam flow
Gate ValveIsolates boiler sections during maintenance
Ball Valve (HP Rated)Quick shut-off in high-temp systems

📍 Industries:

  • Power plants

  • Chemical processing

  • Industrial heating systems

🛠️ Applications in Hydraulic Lines

Valve TypeFunction in Hydraulics
Relief ValvePrevents overpressure damage
Check Valve (NRV)Prevents backflow under high pressure
Pressure Control ValveRegulates pressure across the system
Directional Control ValveManages flow direction of pressurized fluid

📍 Used in:

  • Excavators, cranes, heavy equipment

  • Aerospace hydraulic systems

  • Manufacturing machinery

🔍 Key Features of High-Pressure Valves

  • ✅ Made from stainless steel, alloy steel, or forged steel

  • ✅ Withstand pressures up to 6000 PSI or more

  • ✅ Resist thermal fatigue and corrosion

  • ✅ Include sealing mechanisms to prevent leakage

  • ✅ Often conform to ASME, API, and DIN standards

 How to Select High-Pressure Valves

  1. Check Pressure Rating (PN/PSI)
    ➤ Match with system's max operating pressure

  2. Material Compatibility
    ➤ Use alloy steel or SS for corrosive/hot environments

  3. Application Type
    ➤ Boiler = steam-focused | Hydraulic = oil/fluids

  4. Certifications
    ➤ Prefer API 6D, ASME B16.34, ISO 4126 approved valves

❓ FAQ: People Also Ask

Q1. What valves are best for high-pressure steam?

Safety and globe valves are commonly used for steam in boilers due to their high thermal and pressure tolerance.

Q2. Can ball valves handle high pressure?

Yes, high-pressure ball valves made of forged or stainless steel can handle up to 10,000 PSI depending on design.

Q3. What is the purpose of a relief valve in hydraulics?

A relief valve prevents damage by releasing fluid when pressure exceeds a preset limit in hydraulic circuits.

Q4. Are high-pressure valves expensive?

Yes, due to special materials, pressure rating, and certifications, they cost more than standard valves but offer safety and longevity.
