Plidco Riser Weld + Ends

The Riser Weld+Ends® is socket-welded at the surface to the new replacement riser and lowered into the water. A diver cuts off 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.

PLIDCO® Riser Weld+Ends® are designed to simplify the replacement of underwater risers on offshore oil and gas 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.

Special installation instructions are necessary for thin wall applications. Contact Plidco for details.
