Stourflex strongly advise that anyone installing the JP173 (or indeed any anchor) into a riser have a flange, lug or similar welded onto the pipe to help prevent the anchor slipping.

When accommodating thermal expansion in risers, always consider the effect of the thermal movement on any branch connections, particularly in instances where these branches quickly penetrate fire-stopped walls. Additional steps may be required to protect these branches if insufficient flexibility can be accommodated by the branch prior to penetrating the fire-stopped wall.

Where anchor loads exceed 9kN please refer to the type JP170 Spider Anchor or JP172 Channel Anchor.

Stourflex suspended pipe anchors should be installed in accordance with our fitting instructions a copy of which is supplied with each anchor.
