Water-stop solutions for 100mm pipe penetrations
100mm Puddle Flange Manufacturer in India
Mesta Inc. manufactures 100mm puddle flanges and complete pipe penetration assemblies for concrete walls, slabs and tanks. Moreover, our team follows the purchaser's pipe dimensions, material specification, puddle plate details and approved drawing.
100mm Puddle Flange for Watertight Pipe Penetrations
A 100mm puddle flange forms a water-stop around a pipe that passes through concrete. Specifically, its projecting plate interrupts the direct path between the pipe surface and surrounding concrete. As a result, the product helps limit water tracking along the outside of the penetration.
Mesta Inc. supplies the product as a puddle plate for attachment to a compatible pipe or as part of a complete puddle flange pipe assembly. Furthermore, our team can adapt the design for tanks, treatment plants, basements, foundations and other structures that require a controlled pipe penetration.
However, the description “100mm” alone does not define every required dimension. Depending on the piping system, it may refer to a nominal pipe size or a specified outside diameter. Therefore, we confirm the actual pipe OD, wall thickness, plate projection, plate thickness, material and installation detail before production.
100mm project sizeFirst, our team confirms whether 100mm identifies nominal bore, nominal diameter or actual pipe OD.
Drawing-based dimensionsNext, we follow the approved pipe length, puddle plate OD, thickness and location.
Multiple materialsAdditionally, buyers can request carbon steel, mild steel, stainless steel or selected alloys.
Assembly optionsFinally, buyers can select a welded collar arrangement or a pipe assembly with specified end connections.
100mm Puddle Flange Specifications
The project drawing, piping schedule and approved material requirements determine the final specification. Therefore, the table below identifies the information that our team normally reviews for a 100mm pipe puddle flange.
| Specified size | 100mm; the purchaser confirms the nominal size and actual pipe outside diameter. |
|---|---|
| Pipe dimensions | Outside diameter, wall thickness or schedule, and assembly length as stated in the drawing or BOQ. |
| Puddle plate | Outside diameter, radial projection, thickness, profile and location to the approved penetration detail. |
| Materials | Buyers can specify mild steel, carbon steel, stainless steel or a project-approved alloy, subject to availability and service conditions. |
| End configuration | Plain, bevelled, threaded, socket, flanged or other drawing-defined ends where technically applicable. |
| Flanged ends | When the assembly needs an end flange, the purchaser states its standard, size, class or pressure designation, facing and drilling separately. |
| Joining method | Continuous welded puddle plate or another project-approved attachment method appropriate to the selected material. |
| Surface finish | Bare, primer, paint, hot-dip galvanizing, passivation or project-specified coating where compatible with the base material. |
| Inspection | Our inspectors perform visual and dimensional checks, material verification and weld examination according to the purchase specification. |
| Documentation | Material certificates, dimensional report, weld/NDT records and coating documents when included in the order. |
Size note: Do not assume that every product described as a 100mm or 4-inch puddle flange fits the same pipe. In fact, metric and nominal pipe systems can have different outside diameters. Therefore, provide the pipe standard or measured OD with your enquiry.
Material Options for a 100mm Puddle Flange
Material selection depends on the conveyed medium, external exposure, expected service life, joining method and project specification. Consequently, buyers should compare the service conditions before choosing a grade.
Carbon Steel
For fabricated pipe assemblies, buyers define the applicable material grade, pipe schedule and welding requirements.
Stainless Steel
Alternatively, buyers may choose 304/304L or 316/316L when the project requires improved corrosion resistance or hygiene.
Special Alloys
For demanding environments, engineers may consider duplex, super duplex or nickel-alloy construction after a technical review.
For grade-specific information, review our stainless steel puddle flange and mild steel puddle flange pages.
How to Select the Correct 100mm Puddle Flange
A reliable selection starts with the pipe and penetration drawing rather than the keyword alone. Therefore, confirm these points before ordering:
- Pipe identification: state the governing pipe standard, nominal size and actual outside diameter.
- Wall construction: provide the concrete wall or slab thickness and the required position of the puddle plate.
- Water-stop geometry: define the plate OD, projection and thickness instead of relying on a generic size.
- Material compatibility: match the pipe, plate, weld consumables and coating to the service environment.
- End connections: identify whether the assembly needs plain, bevelled, threaded, socket or flanged ends.
- Installation constraints: account for reinforcement, formwork, access, alignment and required embedment.
Engineering responsibility: The project designer should determine penetration geometry, structural clearances, material suitability and waterproofing details. Afterwards, the manufacturer should follow the approved drawing and specification.
100mm Puddle Flange Manufacturing Process
A controlled production sequence connects the approved dimensions with material identification and final inspection. In addition, each stage supports dimensional consistency and traceability.
Enquiry Review
We review the drawing, pipe OD, wall thickness, plate dimensions, material, coating, quantity and documentation scope.
Material Verification
Next, our team checks the pipe and plate materials against the agreed bill of materials.
Cutting and Preparation
Then, technicians prepare the pipe and water-stop plate to the specified bore, dimensions and edge condition.
Fit-Up
Afterwards, fabricators position the plate at the drawing-defined location and check its alignment.
Welding and Finishing
Where the project specifies welding, qualified personnel follow the approved requirements before cleaning and surface treatment.
Inspection and Dispatch
Finally, inspectors check the dimensions, identification, finish and documents before packing and dispatch.
Quality Control and Inspection
Inspection requirements vary with the material, configuration and project criticality. Therefore, the purchase specification should identify the acceptance criteria and any third-party hold points.
Material Identification
Our team can maintain material markings and certificates throughout fabrication according to the agreed documentation scope.
Dimensional Inspection
Inspectors check pipe OD, length, plate OD, thickness, position, alignment and end details against the drawing.
Weld Examination
Additionally, inspectors can perform visual checks and specified NDT under the approved inspection plan.
Coating Inspection
When the order includes protective coating, the quality team can document surface preparation, finish and coating checks.
Applications of 100mm Puddle Flanges
Designers may specify a 100mm water-stop flange wherever a compatible pipe passes through concrete and the project requires control of water migration. For example, common applications include:
- Underground and above-ground water tanks
- RCC walls, slabs and foundations
- Water and wastewater treatment plants
- STP, ETP and pumping-station structures

100mm Puddle Flange Frequently Asked Questions
What is a 100mm puddle flange?
It is a water-stop component or pipe assembly for a 100mm-class pipe penetration through concrete. Specifically, a plate that projects around the pipe interrupts the path along which water could track between the pipe surface and concrete.
Is a 100mm puddle flange the same as a 4-inch puddle flange?
Not always. Although suppliers may use the terms together commercially, metric and nominal pipe systems can have different outside diameters. Therefore, confirm the pipe standard and actual OD before ordering.
Which dimensions should I supply?
Provide the pipe OD, wall thickness, assembly length, puddle plate OD, plate thickness and plate position. Additionally, include all end-connection and flange details where applicable.
Which materials are available?
Depending on the project, buyers may select mild steel, carbon steel, stainless steel or special alloys. However, our team must confirm availability and suitability against the enquiry.
Can a 100mm puddle flange include flanged ends?
Yes. A complete pipe assembly can include one or more end flanges. In that case, specify the flange standard, nominal size, pressure designation, facing, drilling and orientation separately from the central puddle plate.
Can you customize the puddle plate dimensions?
Yes. Our team can manufacture the outside diameter, projection, thickness and location to an approved drawing, subject to material and fabrication feasibility.
What should I send for a quotation?
