FAQ ( Frequently Asked Questions)
What is a puddle flange?
A puddle flange is a circular metal plate welded around a pipe before it passes through a concrete wall, slab, tank, or foundation. It creates a barrier that prevents water seepage and leakage around the pipe penetration. Puddle flanges are widely used in plumbing, fire fighting, water treatment, and infrastructure projects.
Why is a puddle flange used?
Puddle flanges are used to create a watertight seal where pipes pass through concrete structures. They prevent water ingress, seepage, and structural damage, making them essential for underground tanks, basements, STPs, WTPs, and fire fighting systems.
What materials are puddle flanges made from?
Puddle flanges are commonly manufactured from Mild Steel (MS), Hot Dip Galvanized Steel, Stainless Steel 304, and Stainless Steel 316. The material selection depends on the project’s corrosion resistance requirements and operating environment.
What is a Hot Dip Galvanized Puddle Flange?
A Hot Dip Galvanized Puddle Flange is a mild steel puddle flange coated with zinc through a hot dip galvanizing process. This coating provides superior corrosion resistance and extends the service life of the product in harsh environments.
What is the difference between Stainless Steel 304 and Stainless Steel 316 Puddle Flanges?
Stainless Steel 304 offers excellent corrosion resistance for general applications, while Stainless Steel 316 provides enhanced resistance against chemicals, chlorides, and marine environments. SS316 is preferred for highly corrosive conditions.
What are the standard sizes available for puddle flanges?
Puddle flanges are available in a wide range of standard pipe sizes. Common sizes range from 15 mm to 600 mm and above. Custom sizes can also be manufactured according to project specifications and drawings.
Where are puddle flanges commonly used?
Puddle flanges are widely used in:
- Fire Fighting Systems
- Plumbing Networks
- Water Treatment Plants (WTP)
- Sewage Treatment Plants (STP)
- Data Centers
- Commercial Buildings
- Industrial Facilities
- Underground Water Tanks
- Infrastructure Projects
Can puddle flanges be manufactured in custom sizes?
Yes. We manufacture custom puddle flanges based on pipe diameter, wall thickness, project requirements, and client drawings. Custom fabrication ensures proper fitment and performance.
How does a puddle flange prevent leakage?
The flange becomes embedded within the concrete during casting. This creates a physical barrier that blocks water from passing along the outer surface of the pipe, preventing leakage and seepage.
Are your puddle flanges suitable for fire fighting systems?
Yes. Our puddle flanges are commonly used in fire fighting piping systems where watertight pipe penetrations through walls and tanks are required.
Do you supply puddle flanges across India?
Yes. We supply Hot Dip Galvanized, Mild Steel, and Stainless Steel Puddle Flanges to customers across India, serving contractors, consultants, builders, and EPC companies.
How do I choose the right puddle flange?
The correct puddle flange depends on the pipe size, wall thickness, operating environment, and corrosion resistance requirements. Our technical team can assist in selecting the appropriate material and dimensions for your project.
What industries use puddle flanges?
Puddle flanges are used across multiple industries including construction, water treatment, infrastructure, commercial buildings, manufacturing facilities, data centers, and municipal utility projects.
