Product overview
Flange Adaptor for HDPE / PVC
Plastic pipe behaviour differs from iron and steel. This adaptor is therefore selected with the pipe material, actual OD, wall class or SDR, support arrangement and restraint requirement all visible in the enquiry.
Configuration for compatible plastic-pipe outside diameters.

Selection focus
Four checks for this flange adaptor for HDPE and PVC pipe
- 1Identify HDPE or PVC and provide the printed pipe standard, OD and wall class.
- 2Confirm whether an internal support insert or external restraint is required.
- 3State flange drilling, working pressure, medium and temperature.
- 4Provide the installation layout, pipe support and expected axial load.
Installation notes for Flange Adaptor for HDPE / PVC
- Do not treat HDPE and PVC as mechanically identical.
- Avoid over-tightening that may distort an unsupported plastic pipe.
- The approved drawing defines insertion, restraint and torque requirements.
Choosing Flange Adaptor for HDPE / PVC
Use this page when the enquiry may involve either HDPE or PVC but the exact pipe data will be supplied. Choose the adjustable PE adaptor when PE movement and installation adjustment are central to the connection, and never apply one plastic-pipe detail to another without review.

Frequently asked questions
Flange Adaptor for HDPE / PVC FAQ
Can the same installation detail be used for both HDPE and PVC pipe?
No. HDPE and PVC respond differently to gripping and compression. Identify the pipe material, printed standard, outside diameter and wall class so the seal, support and tightening requirements can be checked separately.
When is an internal support insert required in a plastic pipe flange adaptor?
The requirement depends on the pipe material, SDR or wall class, pressure, temperature and connection design. The approved drawing must state whether an insert is needed and how far it extends through the sealing and gripping zones.
How can pipe distortion be avoided during installation?
Support and align the plastic pipe, keep the adaptor square to the pipe axis and tighten bolts evenly to the approved torque. Do not compensate for poor alignment by over-tightening the gland.
