Closed end cap for industrial pipes
A flexible end cap is provided for the end of an industrial pipe, the end cap comprising a closed end and an open end, the open end defined by a wall extending about the periphery of the closed end, the wall having an interior surface having multiple longitudinal fit beads extending from the interior surface and spaced about the circumference of the interior surface, the longitudinal fit beads extending longitudinally along at least a portion of the interior surface parallel to the longitudinal axis of the end cap, the longitudinal fit beads configured to provide contact along their longitudinal extent with the external surface of a pipe upon the end of the pipe being inserted into the end cap, and the longitudinal fit beads having a tapered end at the uppermost extent thereof.
1 . A flexible end cap for the end of an industrial pipe, said end cap comprising a closed end and an open end, said open end defined by a wall extending about the periphery of said closed end, said wall having an interior surface having multiple longitudinal fit beads extending from said interior surface and spaced about the circumference of said interior surface, said longitudinal fit beads extending longitudinally along at least a portion of said interior surface parallel to the longitudinal axis of said end cap, said longitudinal fit beads configured to provide contact along their longitudinal extent with the external surface of a pipe upon the end of the pipe being inserted into said end cap, and said longitudinal fit beads having a tapered end at the uppermost extent thereof.
2 . The end cap of claim 1 , wherein said longitudinal fit beads are evenly spaced about the entire circumference of said wall.
3 . The end cap of claim 1 , wherein said longitudinal fit beads are present in groups spaced from one another which groups are spaced about the circumference of said wall, said spacing between said groups being greater than the spacing between said longitudinal fit beads.
4 . The end cap of claim 1 , wherein said fit beads have a curved surface.
5 . The end cap of claim 3 , wherein at least one annular fit bead is present in at least one space between said spaced apart groups of longitudinal fit beads.
6 . The end cap of claim 1 , wherein said longitudinal fit beads extend from said closed end to said open end of said end cap.
7 . The end cap of claim 1 , wherein said longitudinal fit beads terminate at a point spaced from said open end.
8 . The end cap of claim 1 , wherein said longitudinal fit beads terminate at a point spaced from said closed end.
9 . The end cap of claim 1 , wherein said longitudinal fit beads extend from a position spaced from said closed end to a position spaced from said open end.
10 . The end cap of claim 1 , wherein said end cap includes multiple radial fit beads along said closed end as stops for said pipe end.
