Fixed SS Puddle Flange
A fixed SS puddle flange uses a permanent plate at a predetermined position on a new pipe or sleeve.
Stainless steel water stops for concrete penetrations
SS Puddle Flange Manufacturer in India
An SS puddle flange creates a corrosion-resistant water stop around a pipe that passes through concrete. Mesta Inc. manufactures each item to the approved drawing; therefore, buyers can specify the stainless grade, pipe size, plate geometry, surface finish and inspection scope.
What Is an SS Puddle Flange?
An SS puddle flange is a stainless steel plate fitted around a pipe or sleeve where it passes through concrete. Because the plate projects beyond the pipe surface, it interrupts the direct path that moisture could follow along the pipe-to-concrete interface.
Stainless steel provides corrosion resistance without relying on a painted coating. However, the correct grade still depends on chloride exposure, chemicals, temperature, fabrication and the required service life.
Mesta Inc. manufactures each component from an approved drawing or complete dimensional enquiry. Consequently, buyers can define the pipe, plate geometry, alloy grade, connection ends, surface condition, inspection and documentation.
Embedded water stopFirst, the projecting plate interrupts water tracking along the outside of the pipe.
Drawing-based dimensionsNext, the project defines pipe OD, plate size, thickness, position and assembly length.
Multiple materialsMoreover, buyers can specify steel, stainless steel, plastics, duplex or special alloys.
Custom pipe endsFinally, assemblies can use plain, bevelled, threaded, socket, spigot or flanged ends.
SS Puddle Flange Specifications and Manufacturing Range
A nominal pipe size does not define the complete product. Therefore, every quotation should confirm the pipe system, water-stop geometry and connection details.
| Pipe size | Project-defined nominal size plus confirmed actual outside diameter. |
|---|---|
| Pipe wall | Schedule, SDR, pressure class or actual wall thickness according to the pipe material. |
| Water-stop plate | Outside diameter or width, radial projection, thickness, profile and pipe opening. |
| Plate position | Drawing-defined location along the pipe and within the concrete wall, slab or tank. |
| Materials | Mild steel, carbon steel, stainless steel, PE, HDPE, PVC or project-approved alloy. |
| Assembly length | Length based on concrete thickness, internal projection, external projection and joint access. |
| End connections | Plain, bevelled, threaded, socket, spigot, single-flanged or double-flanged. |
| Surface finish | Project-specified paint, galvanizing, passivation or compatible protective treatment. |
| Inspection | Material, dimensions, attachment, welds, coating and testing according to the approved plan. |
| Documentation | Material certificates, weld/NDT reports, dimensional records and release documents as agreed. |
Size note: Nominal metric and inch descriptions may use different physical outside diameters. Therefore, provide the pipe standard or measured OD with the enquiry.
Main SS Puddle Flange Types
Installation access and pipe configuration determine the appropriate design. Consequently, compare these principal options.
Adjustable SS Puddle Flange
By contrast, position-adjustable designs provide defined flexibility before final securing.
Loose or Split SS Puddle Flange
For existing pipes, split and loose options may suit restricted-end-access conditions.
SS Puddle Flange Pipe Assembly
A fabricated penetration assembly combines the water stop, pipe and specified end connections.
For a broader comparison, review our design and material guide.
SS Puddle Flange Grades and Selection
The correct stainless specification depends on the conveyed medium, external exposure, temperature, fabrication route and service life. Therefore, compare these options with the project materials engineer:
SS 304 and 304L
These austenitic grades suit many general environments; meanwhile, the low-carbon grade can support specified welded fabrication.
SS 316 and 316L
Molybdenum-bearing grades may improve resistance in some chloride environments, although the actual service still governs selection.
Duplex Stainless Steel
Duplex grades can offer higher strength and chloride resistance when the design, welding procedure and corrosion assessment approve them.
Project-Specified Alloy
Other stainless or special-alloy grades may be supplied when the drawing, material standard and acceptance criteria define them.
Selection note: The term “SS” alone does not define a material. Also confirm the exact grade, product standard, plate geometry, pipe compatibility, fabrication condition and surface finish.
SS Puddle Flange Manufacturing and Installation Process
A controlled sequence connects approved dimensions with material identity, fabrication and site position.
Review the Drawing
First, confirm pipe data, plate dimensions, assembly length, ends and inspection requirements.
Verify Materials
Next, match pipe, plate, fitting and flange materials with the approved bill of materials.
Prepare Components
Then, cut the pipe and plate and prepare all required openings, edges and connection ends.
Fit and Attach
Fabricators set the water-stop position and complete the approved welded, bonded or mechanical attachment.
Inspect and Finish
Afterwards, inspectors check dimensions, joints, ends, surface treatment and identification.
Set in Concrete
Finally, installers support the assembly while workers consolidate concrete around the complete plate.
SS Puddle Flange Quality Control and Testing
Inspection should address the manufactured product and its final position before concrete placement. Accordingly, typical checks include:
Material Traceability
First, markings and certificates connect each component with the approved specification.
Dimensional Verification
Next, inspectors verify pipe OD, length, plate geometry, position and connection orientation.
Attachment Examination
Moreover, the team checks the specified weld, bond, clamp or mechanical joint.
Pre-Pour Inspection
Finally, site personnel verify line, level, support, reinforcement clearance and concrete access.
SS Puddle Flange Applications
Projects use embedded water stops wherever pipes pass through concrete exposed to stored water, groundwater or wet service. For example, applications include:
- Tank inlet, outlet, drain and overflow penetrations
- Fire-water tank and pump-room connections
- Concrete wall and basement penetrations
- Slab and foundation penetrations
- Drain and wastewater services
- STP, ETP, water-treatment and industrial utility structures
- Tunnels, shafts, pits, sumps and chambers
For the water-stop design context, review our pipe-penetration waterproofing guide. In addition, the independent WBDG below-grade systems guide explains broader moisture-control considerations for concrete structures.

SS Puddle Flange Frequently Asked Questions
What is an SS puddle flange?
It is a stainless steel water-stop plate fitted around a pipe or sleeve embedded in concrete. The plate helps interrupt moisture movement along the pipe-to-concrete interface.
Where is an SS puddle flange used?
Projects use it in tanks, walls, slabs, basements, treatment structures and other concrete penetrations where stainless steel is appropriate.
Does it connect two pipes?
The central water-stop plate does not connect pipes. However, a complete assembly may include separate end flanges, sockets, spigots or other connections.
Which stainless steel grades are available?
Common project-specified options include 304, 304L, 316, 316L and duplex grades. However, the service and corrosion assessment should determine the final grade.
How do I select the correct size?
Confirm the actual pipe OD, wall, plate dimensions, concrete thickness and assembly length instead of relying only on nominal size.
Does it replace a waterproofing membrane?
No. It controls the embedded pipe interface, while membranes, waterbars, linings and pipe-joint seals address other leakage paths.
What information is needed for a quote?
First, send the drawing or pipe data. Then, include the plate geometry, material, connections, finish, inspection, quantity and delivery requirements.
