Plidco Riser-Type Weld + End

The PLIDCO® Riser-Type Weld+Ends® are an easy way to replace underwater risers on off-shore gas and oil lines without the need to weld. This fitting consists of additional clamp and thrust screws to provide a secure seal for high pressure and to resist extreme end-pull.

The PLIDCO® Riser-Type Weld+Ends® are socket welded at the surface to the new replacement riser then lowered into the water. The diver then cuts the old riser, and places the new fitting over the cut pipe and tightens screws to complete the installation creating a leak proof seal.
