Flange-to-Plain End
A bolted flange at one end and a square-cut plain end at the other can suit compatible mechanical couplings.
Custom pipe spools with one flanged connection
Single Flanged Pipe Manufacturer in India
A single flanged pipe is a fabricated pipe spool with one bolted flange and a project-defined connection at the opposite end. Mesta Inc. manufactures each unit to the approved drawing; therefore, buyers can specify the pipe size, flange standard, pressure class, material, overall length and second-end preparation.
What Is a Single Flanged Pipe?
A single flanged pipe has a flange permanently attached to only one end of its pipe barrel. The other end remains plain, bevelled, threaded, socketed or spigot-ended so that it can match a different joining method.
This configuration provides a removable bolted connection on one side while supporting welding, coupling or push-fit assembly on the other. When required for a concrete penetration, the spool can also include an integral puddle plate at a drawing-defined position.
Mesta Inc. manufactures every spool from an approved drawing or complete dimensional enquiry. Consequently, the finished product can match the specified pipe standard, flange drilling, facing, orientation, end preparation, coating and inspection plan.
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.
Single Flanged Pipe 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. |
| Flange details | Standard, nominal size, pressure class, facing, drilling, thickness and material. |
| Puddle plate | Optional drawing-defined water-stop plate for an embedded wall, slab or tank penetration. |
| 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. |
| Opposite end | Plain, bevelled, threaded, socket or spigot according to the piping layout. |
| 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.
Single Flanged Pipe End Configurations
The adjoining pipeline and site joining method determine the correct opposite-end preparation. Consequently, compare these common configurations.
Flange-to-Bevel End
A bevelled opposite end prepares the spool for a specified butt-weld connection in a compatible piping system.
Flange-to-Threaded End
A project-defined male or female thread provides a compact connection when the service and pipe size permit threaded joining.
Flange-to-Spigot End
A flange-and-spigot configuration combines a bolted joint with a compatible socket or push-fit connection.

Single Flanged Pipe Materials and Selection
The correct material depends on the pipe, conveyed medium, surrounding environment, joining method and service life. Therefore, compare these common categories:
Mild and Carbon Steel
These materials offer flexible fabrication. However, the project should specify corrosion protection for the exposure.
Stainless Steel
Corrosion-resistant steel options may suit wet, hygienic or aggressive environments.
PE and HDPE
Polyethylene options require the correct PE grade, SDR, OD and fabrication method.
Duplex and Nickel Alloy
Special alloys may suit demanding chloride or chemical exposure when the project specifies them.
Selection note: Material compatibility alone does not complete the design. Also confirm plate geometry, attachment, movement, concrete clearance and end connections.
Single Flanged Pipe 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.
Single Flanged Pipe 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.
Single Flanged Pipe 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.

Single Flanged Pipe Frequently Asked Questions
What is a single flanged pipe?
It is a fabricated pipe spool with one flanged end and a different connection preparation at the opposite end.
Where is a single flanged pipe used?
Projects use it for valve, equipment, tank, pump and pipeline connections, as well as concrete penetrations when an optional puddle plate is specified.
Which flange details must I provide?
Specify the applicable standard, nominal size, pressure class, facing, drilling and material. Also identify the required orientation when bolt-hole position matters.
Which materials are available?
Options may include mild steel, carbon steel, stainless steel, PE, HDPE, PVC, duplex and project-approved special alloys.
How do I select the correct assembly size?
Confirm the pipe OD, wall thickness, flange details, opposite-end preparation and overall face-to-end length instead of relying only on nominal size.
Can it include a puddle plate?
Yes. A drawing-defined water-stop plate can be added when the spool passes through a concrete wall, slab or tank structure.
What information is needed for a quote?
First, send the drawing or pipe data. Then, include the flange specification, opposite-end preparation, material, length, finish, inspection scope and quantity.
