Abstract:
A corrosion-resistant alloy tube is formed and bonded to a pre-machined steel alloy rod to form a riser tensional cylinder rod. During assembly, an epoxy is injected into an annular space between the tube and rod and then cured. The bonded tube is ground to a desired surface finish prior to installation and utilizes a double seal arrangement that prevents external pressure or corrosive fluids from entering the cured epoxy in the annular space.
