Default Pipe instead of ground rod

Can a 1/2 inh plumbing pipe or rebar be used near the seashore instead of a ground rod and what purpose does it serve?

not less than 8 feet (2438 mm) in length and consisting
of the following materials shall be considered as a
grounding electrode:
1. Electrodes of pipe or conduit shall not be smaller than
trade size 3/4 (metric designator 21) and, where of iron
or steel, shall have the outer surface galvanized or
otherwise metal-coated for corrosion protection.
2. Electrodes of rods of iron or steel shall be at least 5/8
inch (15.9 mm) in diameter. Stainless steel rods less
than 5/8 inch (15.9 mm) in diameter, nonferrous rods
or their equivalent shall be listed and shall be not less

depth of not less than 8 feet (2438 mm) except that,
where rock bottom is encountered, electrodes shall be
driven at an oblique angle not to exceed 45 degrees from
the vertical or shall be buried in a trench that is at least 30
inches (762 mm) deep. The upper end of the electrodes
shall be flush with or below ground level except where
