For
easier replacement of underwater risers
PLIDCO
Riser-Type Weld+Ends are designed to simplify the replacement of
underwater risers on offshore gas and oil lines–without welding
underwater.
This fitting has additional clamping and thrust screws to provide a seal
for high pressure and for resisting extreme end-pull.
Installation is rapid. The Riser-Type Weld+Ends is socket-welded at the
surface to the new replacement riser and lowered into the water. A diver
cuts out the old riser, stabs the new fitting over the cut-off pipe,
then tightens the clamping and thrust screws for a complete leak proof
seal without welding.
Available in all standard sizes; special sizes as specified. Buna-N
packing is standard, other packing available on application. |
