Spiral Rib Pipes for Storm Sewer Projects
Spiral rib pipes feature better hydraulic efficiency
than traditional integral or spiral corrugated pipes
and they are widely used for various storm sewer
projects or acting as liner pipe for rehabilitating
existing culverts. Made of quality galvanized or
polymer coated steel, spiral rib pipes have lock-seam
structures with external ribs formed by passing through
roll forming line. Decades of uses have proven spiral
rib pipe is one revolutionary product that combines
following advantages together.
A galvanized round spiral rib pipe with smooth interior
surface for eliminating most boundary turbulence and
providing great liquid flow.
Spiral rib pipe with square-shaped ribs projecting to
the pipe's exterior.
Superb hydraulic design
Spiral rib pipes features smooth interior that provides
superb hydraulic efficiency equal to that of concrete
or HDPE pipes. With a Manning's "n" factor of 0.012,
spiral rib pipes can be used interchangeably with
concrete and HDPE pipes without affecting flow
High strength & durability
Spiral rib pipes feature high stiffness and less
inclination to deflect. Meanwhile, lock-seam
connections strengthen the pipe and heavy zinc &
polymer coatings allow for great corrosion resistance
and a longer lifespan than traditional concrete pipes.
Three galvanized round spiral rib pipes are galvanized
to resistant against corrosion.
Spiral rib pipe are galvanized to resistant against
rust and corrosion.
Big cost saving
Spiral rib pipes have lower price compared with
concrete pipes and plastic pipe. This price difference
may more visible when taking the cost of prefabricated
fittings and accessories into consideration. In
addition, spiral rib pipes are only 1/10 time the
weight of traditional concrete pipes in same
specification. And this weight reduction allows for
quicker handling and installation as well as a
considerable saving of labor cost.
Spiral rib pipes can be manufactured in round shapes
from 15" to 120" in diameter and 16 gauge to 10 gauge
in wall thickness. Meanwhile, they are galvanized or
polymer coated to protect these pipes from rust and
corrosion. Custom sizes can be fabricated if required
by the projects.
