ABSTRACT:
A clamping device supports or structurally replaces a weld joint between connected pipes. The clamping device includes an upper clamp body and a lower clamp body securable on opposite sides of the connected pipes in facing relation, and at least one clamp bolt connecting the upper and lower clamp bodies and extendable through the connected pipes. One of the upper and lower clamp bodies has at least one shaped depression, which receives a complementary shaped clamp bolt nut engageable with the clamp bolt. The shaped depression prevents rotation of the clamp bolt nut.
