Product overview
Flange Adaptor for DI Pipe
The DI Flange Adaptor narrows the selection to ductile iron pipe rather than a broad universal OD range. It is suited to planned DI networks where the pipe standard, outside diameter and mating flange can be confirmed before manufacture.
Pipe-specific option documented for ductile iron pipe connections.

Selection focus
Four checks for this flange adaptor for ductile iron pipe
- 1Provide the DI pipe standard, nominal size and measured outside diameter.
- 2Confirm the mating flange drilling and pressure class.
- 3State whether the line has separate thrust restraint.

Installation notes for Flange Adaptor for DI Pipe
- Check the pipe surface for ovality, damage and coating build-up.
- Maintain an even annular gap before tightening the gland.
- Use only the approved lubricant and torque table.
Choosing Flange Adaptor for DI Pipe
A DI-specific adaptor is the clearer choice when the pipe material and OD are fixed in the bill of quantities. Compare the universal adaptor for mixed legacy networks or uncertain OD bands; consider restraint only when the piping design requires axial grip.

Frequently asked questions
Flange Adaptor for DI Pipe FAQ
Why use a flange adaptor designed specifically for ductile iron pipe?
A DI-specific adaptor gives a focused connection when the pipe standard and outside diameter are known. It avoids treating a controlled DI pipeline as an uncertain mixed-material network and makes the required flange drilling easier to define.
What pipe-end checks are required before fitting the DI adaptor?
Inspect the pipe for coating build-up, ovality, damage and contamination where the gasket will seal. Measure the outside diameter at several points and prepare a clean, sound sealing surface.
Which flange details must be stated for a DI pipe connection?
Provide the mating flange standard, nominal size, pressure class and drilling pattern. The bolt set, gasket compound and corrosion protection should also match the project specification.
