Drawing-based water stops for DN65 pipe penetrations

65mm Puddle Flange Manufacturer in India

Mesta Inc. manufactures 65mm puddle flanges for tanks, pump rooms, treatment plants and concrete-wall penetrations. First, we verify the pipe standard and actual OD; then, we follow the approved plate dimensions, sleeve length and connection details.

65mm Puddle Flange for Medium-Bore Pipe Penetrations

A 65mm pipe penetration often serves water distribution, pump-room drainage or tank connections. However, water can follow the interface between the pipe and concrete when the detail lacks a suitable water-stop barrier.

A 65mm puddle flange places a projecting plate around the pipe or sleeve. Consequently, the plate interrupts the direct seepage path through the concrete. It therefore supports the penetration design for tanks, chambers, walls, slabs and treatment facilities.

Mesta Inc. manufactures standalone puddle collars and complete 65mm puddle flange pipe assemblies. Buyers can define the material, plate geometry, sleeve length and end connections according to their approved drawing.

DN65 size reviewWe verify the dimensional standard and actual OD before confirming the component bore.
2½-inch comparisonDN65 and nominal 2½-inch descriptions still require confirmation against the selected pipe system.
Custom water-stop plateThe project drawing controls the plate OD, thickness, profile and embedment position.
Multiple end optionsAssemblies can use plain, bevelled, threaded, socket or flanged ends where applicable.

65mm Puddle Flange Specifications

The terms 65mm, DN65 and 2½ inch do not define every physical dimension. In fact, the pipe OD and wall depend on the material and dimensional standard. Therefore, the purchaser should identify the complete pipe system in the enquiry.

Size designation65mm or DN65; purchaser to confirm the governing pipe standard and actual outside diameter.
Inch referenceCommonly associated with nominal 2½-inch pipe, subject to dimensional verification.
Pipe wallSchedule, SDR, pressure class or actual wall thickness according to the pipe system.
Pipe materialsMild steel, carbon steel, stainless steel, PVC, uPVC, HDPE or another approved material.
Plate diameterTotal OD or radial projection beyond the pipe as the penetration detail specifies.
Plate thicknessProject-defined value compatible with material, attachment method and service.
Sleeve lengthLength based on wall thickness, required projection and site-connection access.
End connectionsPlain, bevelled, threaded, socket, spigot or flanged ends where technically suitable.
Surface protectionCompatible primer, paint, galvanizing, passivation or project-defined finish.
InspectionMaterial, dimensional, joint, coating and documentation checks as agreed.

Dimensional note: Do not select the puddle flange bore from “65mm” alone. Instead, send the pipe material, standard and measured outside diameter so the assembly matches the intended pipe.

65mm Pipe and Material Compatibility

Material affects the dimensional system, attachment method, corrosion resistance and available end connections. Consequently, each order requires a complete material and pipe designation.

65mm MS or Carbon Steel

Define the pipe grade, schedule, weld scope and coating. In addition, specify any required bolted end flange separately.

65mm Stainless Steel

For corrosive or hygienic service, state the stainless grade, wall, finish and material-certification requirements.

65mm PVC or uPVC

Provide the dimensional standard, pressure class and actual OD together with an approved plastic-compatible attachment method.

65mm HDPE Pipe

Identify the PE grade, SDR and OD. Moreover, coordinate the assembly with the specified joining and movement requirements.

Compare stainless steel puddle flanges, MS puddle flanges and PE puddle flanges.

Selecting the Water-Stop Plate for a 65mm Pipe

The plate must provide the drawing-defined obstruction without creating congestion around reinforcement. Therefore, coordinate these design points:

  • Confirmed pipe OD: match the component bore to the actual pipe dimensions.
  • Plate projection: define how far the water stop extends beyond the pipe surface.
  • Plate thickness: select a thickness that suits the material and fabrication process.
  • Embedment position: locate the plate within the concrete section according to the approved detail.
  • Bar clearance: prevent clashes between the plate, reinforcement and embedded items.
  • Connection space: allow access for threads, sockets, unions, flanges or other external joints.

System note: The central puddle plate acts as the water stop in the concrete. By contrast, an end flange provides a separate piping connection and needs its own standard, rating, facing and drilling details.

65mm Puddle Flange Fabrication and Installation

A controlled sequence links the approved penetration drawing with the finished assembly and its site position.

Step 01

Review the Pipe Data

First, confirm the material, standard, OD, wall thickness, service and connection ends.

Step 02

Check the Penetration Detail

Next, verify the wall thickness, plate dimensions, plate position and assembly length.

Step 03

Fabricate the Water Stop

Then, prepare the pipe and plate and complete the approved material-compatible attachment.

Step 04

Inspect the Assembly

Inspectors check dimensions, plate alignment, joint condition, ends and finish before release.

Step 05

Position and Support

At site, installers maintain the required line, level and end projection during concrete work.

Step 06

Finish the Pipe Connection

Finally, the site team examines the exposed ends before completing joints and specified tests.

Quality Checks for a 65mm Puddle Flange

The inspection plan should verify that the assembly matches both the pipe system and penetration drawing. Accordingly, typical checks include:

Size and Bore

Inspectors compare the manufactured bore or pipe OD with the confirmed dimensional standard.

Water-Stop Geometry

They verify the plate OD, thickness, position and alignment against the approved drawing.

Attachment Integrity

The team examines the welded, bonded, fabricated or mechanical attachment as required.

Ends and Finish

Finally, inspectors check connection details, surface protection, marking and agreed documents.

Applications of 65mm Puddle Flanges

Projects use 65mm puddle flanges for medium-bore services that cross concrete boundaries. For example, common project-defined applications include:

  • Water-tank inlet, outlet and drain connections
  • Pump-room suction, discharge and auxiliary lines
  • STP, ETP and water-treatment penetrations
  • Sumps, pits and valve chambers
  • Basement and retaining-wall pipe entries
  • Industrial service-water and utility systems
  • Fire-water tank and pump-house auxiliary connections

Additionally, buyers can review water-tank puddle flanges, concrete-wall penetrations and fire-water applications.

65mm Puddle Flange Frequently Asked Questions

What is a 65mm puddle flange?

It is a water-stop collar or pipe assembly for a compatible 65mm-class penetration through concrete. Its projecting plate helps interrupt seepage along the outside of the pipe.

Is a 65mm puddle flange the same as DN65?

Suppliers often associate these descriptions. Nevertheless, buyers should confirm the governing standard and actual pipe OD before ordering.

Is 65mm the same as 2½-inch pipe?

Not automatically. Nominal metric and inch descriptions may refer to a similar size class, but the physical OD depends on the pipe standard and material.

Can a 65mm assembly include an end flange?

Yes. In that case, specify the flange standard, size, pressure designation, facing, drilling and orientation separately from the puddle plate.

Which materials can I request?

Subject to feasibility, buyers can request mild steel, carbon steel, stainless steel, PVC, uPVC, HDPE or another approved material.

Where can projects use a 65mm puddle flange?

Typical uses include tanks, pump rooms, treatment plants, sumps, valve chambers and service-water penetrations.

What information should I send for a quote?

Send the pipe standard, actual OD, wall, material, plate dimensions, sleeve length, connection ends, quantity and drawing.
