80mm Puddle Flange Manufacturer in India
Mesta Inc. manufactures 80mm puddle flanges for tank outlets, drains, treatment plants and RCC wall penetrations. First, we verify the pipe standard and actual OD; then, we follow the approved water-stop dimensions, sleeve length and end details.
80mm Puddle Flange for Tank Outlets and Drain Lines
An 80mm pipe often carries tank discharge, drainage, overflow or utility water through concrete. However, moisture can track along the outside of the pipe when the penetration lacks a suitable water-stop detail.
An 80mm puddle flange adds a continuous plate around the pipe or sleeve. Consequently, the plate extends the seepage path and creates a physical obstruction inside the concrete. It therefore supports watertight penetrations through RCC walls, slabs, tanks and chambers.
Mesta Inc. manufactures individual puddle collars and complete 80mm puddle flange pipe assemblies. Buyers can define the pipe material, water-stop dimensions, assembly length, end connections and inspection scope.
DN80 size verificationWe confirm the pipe standard and physical OD before setting the bore or assembly dimensions.
3-inch comparisonDN80 and nominal 3-inch descriptions still require dimensional verification.
Tank and drain dutyThe size suits project-defined outlets, overflows, drains and utility penetrations.
Custom assembly scopeBuyers can specify plate dimensions, sleeve length, materials and connection ends.
80mm Puddle Flange Specifications
The descriptions 80mm, DN80 and 3 inch identify a nominal size class rather than one universal outside diameter. In fact, plastic and metallic pipe systems follow different dimensional standards. Therefore, the RFQ should state the complete pipe designation.
| Size designation | 80mm or DN80; purchaser to confirm the governing standard and actual pipe OD. |
|---|---|
| Inch reference | Commonly associated with nominal 3-inch pipe, subject to dimensional verification. |
| Pipe wall | Schedule, SDR, pressure class or measured wall thickness as applicable. |
| Pipe materials | Mild steel, carbon steel, stainless steel, PVC, uPVC, HDPE or approved equivalent. |
| Water-stop plate OD | Total diameter or radial projection according to the approved penetration detail. |
| Plate thickness | Project-defined thickness compatible with the selected material and attachment method. |
| Assembly length | Length based on concrete thickness, end projections and site-connection requirements. |
| End configurations | Plain, bevelled, socket, spigot, threaded or flanged ends where technically suitable. |
| Surface finish | Compatible paint, galvanizing, passivation or another project-specified treatment. |
| Inspection records | Agreed material, dimensional, joint, coating and release documentation. |
80mm versus 3-inch: Do not approve the bore from these labels alone. Instead, provide the pipe material, dimensional standard and measured OD so the puddle flange fits the intended pipe.
80mm Pipe and Material Options
The base material affects dimensions, attachment, corrosion protection and connection methods. Consequently, buyers should define the pipe system before finalizing the assembly.
80mm Stainless Steel
Where corrosion or hygiene matters, state the stainless grade, wall thickness, finish and certification scope.
80mm PVC or uPVC
Provide the plastic standard, pressure class and actual OD together with the approved attachment detail.
80mm HDPE Pipe
Identify the PE grade, SDR and OD. Furthermore, coordinate jointing and movement requirements with the penetration design.
Compare stainless steel puddle flanges, MS puddle flanges and PE puddle flanges.
Water-Stop Plate Design for an 80mm Pipe
The approved plate must provide the required obstruction while allowing concrete to surround it fully. Therefore, the penetration drawing should define these points:
- Pipe OD: match the component to the actual dimensions of the chosen pipe system.
- Plate projection: specify the radial width beyond the outside pipe surface.
- Plate thickness: coordinate thickness with material, fabrication and service requirements.
- Plate location: show the required position within the concrete wall or slab.
- Structural clearance: avoid clashes with reinforcement, joints and other embedded components.
- End projection: preserve enough accessible pipe for the planned external connections.
Waterproofing note: The puddle plate controls water tracking along the pipe-to-concrete interface. Nevertheless, the project designer must coordinate it with the complete structural, joint-sealing and waterproofing system.
80mm Puddle Flange Fabrication and Installation
A coordinated sequence protects the assembly dimensions and water-stop position from production through concrete placement.
Verify the Pipe Standard
First, confirm the material, actual OD, wall, service and planned connection method.
Review Plate Geometry
Next, check the plate OD, thickness, location and assembly length against the drawing.
Complete Fabrication
Then, prepare the pipe and plate and use the approved material-compatible attachment process.
Inspect Before Dispatch
Inspectors verify dimensions, alignment, joint condition, end details and surface finish.
Set Line and Level
At site, installers position and support the assembly before reinforcement and concrete work.
Finish Site Connections
Finally, inspect the exposed ends and complete the specified joints when construction permits.
Quality Checks for an 80mm Puddle Flange
The inspection plan should connect the manufactured component to the approved pipe and penetration detail. Accordingly, typical checks include:
OD and Bore Check
Inspectors compare the manufactured dimensions with the confirmed DN80 pipe system.
Plate Geometry
They verify plate OD, thickness, position and alignment against the approved drawing.
Joint Examination
The team checks the welded, bonded, fabricated or mechanical attachment as specified.
Connection and Finish
Finally, inspectors review the ends, surface protection, marking and agreed records.
Applications of 80mm Puddle Flanges
Projects commonly use 80mm penetrations for drainage, tank discharge and water services. For example, suitable project-defined applications include:
- Water-tank outlets, drains and overflow lines
- RCC sump and collection-pit penetrations
- STP, ETP and wastewater drainage connections
- Pump-room drains and service-water pipe entries
- Basement and retaining-wall penetrations
- Valve chambers and utility structures
- Industrial wash-water and process-drain services
Additionally, buyers can review water-tank puddle flanges, drain puddle flanges and concrete-wall penetrations.

80mm Puddle Flange Frequently Asked Questions
What is an 80mm puddle flange?
It is a water-stop collar or pipe assembly for a compatible 80mm-class penetration through concrete. Its projecting plate helps interrupt water movement along the outside of the pipe.
Is an 80mm puddle flange the same as DN80?
Suppliers often use both descriptions for the same nominal size class. However, buyers must still confirm the pipe standard and actual OD.
Is 80mm the same as 3-inch pipe?
Not necessarily. Metric and nominal-inch descriptions may indicate a similar size class, but the physical outside diameter depends on the material and standard.
Can I use an 80mm puddle flange for a tank outlet?
A designer may specify it for a compatible tank outlet, drain or overflow. Nevertheless, the drawing must define the pipe, plate, wall and connection details.
Can an 80mm assembly include flanged ends?
Yes. Specify the end-flange standard, pressure designation, facing, drilling and orientation separately from the central water-stop plate.
Which materials can buyers request?
Subject to feasibility, options can include mild steel, carbon steel, stainless steel, PVC, uPVC and HDPE.
What should I send for a quotation?
Send the pipe standard, actual OD, wall, material, plate dimensions, sleeve length, ends, quantity and approved drawing.
