Stainless steel grade 321 internal flow sleeve fitted as standard. External protective sleeve available on request.

Where service conditions above 300ºC or 16 bar exist or where additional movement is required non standard variations of the Type JP116VS are available if required.

Alternative flange drillings are available.

Stourflex axial expansion joints are supplied at their neutral length shown above and can be extended on installation (cold draw) to achieve total movement. Do not exceed total movement..

Axial expansion joints must be securely anchored and adequately guided to ensure their correct performance. Omitting anchors and guides may result in failure of the system.

All Stourflex products should be installed in accordance with our fitting instructions.
