90mm HDPE Pipe
Provide the PE grade, SDR, standard and actual OD. Furthermore, coordinate fabrication with the specified jointing and movement requirements.
Water stops sized to the actual 90mm pipe system
90mm Puddle Flange for Pipe Penetrations
Mesta Inc. manufactures 90mm puddle flanges for PVC, uPVC, HDPE and custom metallic pipe penetrations. First, we verify the actual OD and pipe wall; then, we follow the approved plate dimensions, attachment method and assembly details.
90mm Puddle Flange for Plastic and Metal Pipe Systems
A 90mm pipe can pass through a concrete tank, chamber, wall or slab as part of a water, drainage or utility system. However, the pipe-to-concrete interface can provide a route for moisture when the penetration lacks a suitable water stop.
A 90mm puddle flange places a projecting plate around the pipe. Consequently, the plate interrupts the direct path along the outside surface and becomes embedded within the concrete. It therefore supports the approved waterproofing detail for the penetration.
The term “90mm” commonly describes an outside diameter in plastic pipe systems. Nevertheless, the exact meaning depends on the pipe material and standard. Mesta Inc. therefore verifies the OD, SDR or wall, plate dimensions and attachment method before manufacturing the component.
Actual-OD applicationMany plastic systems use 90mm as an outside-diameter designation, but the standard still requires confirmation.
SDR-dependent wallFor PE and other plastic pipe, the SDR or pressure class helps define the wall thickness.
Material-compatible attachmentThe approved method must suit PVC, uPVC, HDPE or the selected metallic pipe.
Drawing-defined water stopThe project controls plate projection, thickness, position and assembly length.
90mm Puddle Flange Specifications
A 90mm designation can identify the actual OD of a plastic pipe, but buyers should not assume universal compatibility. In particular, material, SDR, pressure class and dimensional standard affect the component fit. Therefore, provide the full pipe designation with the enquiry.
| Specified size | 90mm; purchaser to confirm whether this identifies actual OD or another nominal designation. |
|---|---|
| Plastic pipe data | Material, dimensional standard, PE grade where applicable, SDR or pressure class and measured OD. |
| Metal pipe data | Material grade, dimensional standard, outside diameter and wall thickness or schedule. |
| Puddle plate OD | Total diameter or radial projection beyond the 90mm pipe according to the approved drawing. |
| Plate thickness | Project-defined thickness compatible with the selected material and attachment method. |
| Plate position | Drawing-defined location within the concrete section and coordinated with reinforcement. |
| Assembly length | Length based on wall thickness, end projections and connection access. |
| Connection ends | Plain, socket, spigot, threaded, bevelled or flanged ends where applicable. |
| Surface requirements | Material-appropriate cleaning, coating, galvanizing, passivation or other specified finish. |
| Inspection | Fit, dimensions, joint integrity, finish and documentation according to the purchase order. |
OD note: Even when the pipe carries a 90mm marking, confirm its measured OD and standard. Therefore, Mesta Inc. can match the water-stop component to the actual pipe rather than relying on the label alone.
90mm Pipe Material and Attachment Options
The pipe material determines how the water-stop component fits and attaches. Consequently, the approved drawing should identify both the base material and joining method.
90mm PVC or uPVC Pipe
State the material standard, pressure class and measured OD together with the approved plastic-compatible attachment detail.
90mm Steel Assembly
For custom steel pipe, define the actual OD, wall, grade, weld scope, coating and connection ends.
90mm Stainless Assembly
Where corrosion resistance matters, specify the grade, wall thickness, finish and material documentation.
For material-specific options, review PE puddle flanges, stainless steel puddle flanges and MS puddle flanges.
Designing a Water-Stop Plate for 90mm Pipe
The plate must suit the pipe OD while maintaining enough clearance for reinforcement and concrete. Therefore, the project detail should define:
- Component bore: match the bore or fabricated assembly to the confirmed pipe OD.
- Plate projection: specify the radial width beyond the 90mm pipe surface.
- Plate thickness: coordinate thickness with material stiffness and attachment method.
- Embedment position: locate the plate within the wall or slab according to the approved detail.
- Pipe movement: address thermal movement, settlement or flexibility where the design requires it.
- Concrete clearance: prevent congestion around the plate and nearby reinforcement.
Compatibility note: Do not weld a metallic plate directly to plastic pipe. Instead, use the material-compatible arrangement that the approved product design and pipe-system requirements specify.
90mm Puddle Flange Fabrication and Installation
The workshop and installation teams should preserve the specified fit, plate location and pipe alignment throughout the process.
Identify the Pipe
First, verify the material, standard, measured OD, SDR or wall and pressure class.
Approve the Water-Stop Detail
Next, confirm the plate OD, thickness, position, attachment method and assembly length.
Manufacture the Component
Then, prepare and join the compatible materials according to the approved fabrication detail.
Inspect Fit and Dimensions
Inspectors check the pipe fit, plate geometry, assembly ends, identification and finish.
Position the Pipe
At site, installers support the penetration to maintain line, level and end projection.
Complete Concrete Work
Finally, workers place concrete around the full plate while protecting the assembly from movement.
Quality Checks for a 90mm Puddle Flange
Inspection should confirm compatibility with the actual pipe system rather than only the nominal description. Accordingly, typical checks include:
Actual OD and Fit
Inspectors compare the pipe measurement with the component bore or fabricated assembly dimensions.
Plate Dimensions
They verify plate OD, projection, thickness, location and alignment against the drawing.
Attachment Review
The team examines the material-specific fabricated, bonded, welded or mechanical arrangement.
Identification and Finish
Finally, inspectors check pipe data, product marking, ends, finish and required records.
Applications of 90mm Puddle Flanges
The 90mm size often suits plastic water, drainage and utility systems. For example, project-defined applications may include:
- HDPE and PVC water lines through RCC structures
- Tank inlet, outlet, drain and overflow penetrations
- STP, ETP and wastewater chambers
- Irrigation and landscape-water pipe entries
- Pump-room and utility-building penetrations
- Basement walls, sumps and collection pits
- Process-water and non-potable-water services
Additionally, buyers can review PE puddle flanges, water-tank applications and concrete-wall penetrations.

90mm Puddle Flange Frequently Asked Questions
What is a 90mm puddle flange?
It is a water-stop component for a compatible 90mm pipe penetration through concrete. Its projecting plate helps interrupt water movement along the pipe-to-concrete interface.
Does 90mm normally describe the pipe OD?
It often describes the outside diameter in plastic pipe systems. However, buyers should still confirm the material, standard and measured OD.
Can you make a puddle flange for 90mm HDPE pipe?
Yes, subject to design and fabrication review. Provide the PE grade, SDR, pipe standard, measured OD and approved attachment detail.
Can you make one for 90mm PVC or uPVC?
Yes, subject to compatibility review. First, specify the material standard and pressure class. Then, provide the actual OD and approved joining method.
Which plate dimensions should I provide?
Provide the total plate OD or radial projection, thickness and position. Additionally, include the concrete thickness and pipe length.
Can a 90mm assembly include connection ends?
Yes. Depending on the pipe system, buyers can specify plain, socket, spigot, threaded, bevelled or flanged ends.
