CORRUGATED METAL PIPE
Galvanized Steel - Aluminized Steel - Aluminum Alloy
PACIFIC

CORRUGATED PIPE CO.
CORRUGATED METAL PIPE (CSP, CASP, CAP)
Corrugated metal pipe is used extensively in flood control,
drainage and sewer systems because of its economic value,
strength and durability. The pipe is usually fabricated in 20foot sections; however, sections in other lengths are
available. The available diameters range from 6 inches to
96 inches and the available wall thicknesses are .052
inches (18 gauge), .064 inches (16 gauge), .079 inches
(14 gauge), .109 inches (12 gauge), .138 inches (10
gauge) and .168 inches (8 gauge). The pitch of the
corrugation is two and two-thirds inches and the depth is
one-half inch. For 6-, 8-, and 10-inch pipe the pitch is one
and one-half inches and the depth is one-fourth inch. (See
detail on this page for definitions of pitch and depth.)
CORRUGATED METAL PIPE-ARCH (CSPA, CASPA,
CAPA)
Corrugated metal pipe-arch performs the same function as
round pipe and is used primarily where there is limited
headroom or cover over the pipe or where the hydraulic
conditions necessitate its use. Corrugated metal pipe-arch,
like corrugated metal pipe, is usually fabricated in 20-foot
sections, although sections of other lengths are available.
The pipe-arch is available in many sizes. The minimum span
x rise is 17 x 13 inches and the maximum is 83 x 57
inches. The available wall thicknesses are .064 inches (16
gauge), .079 inches (14 gauge), .109 inches (12 gauge),
.138 inches (10 gauge), and .168 inches (8 gauge). The
pitch of the corrugations is two and two-thirds inches, and
the depth is one-half inch (see detail on this page for
definitions of pitch and depth).
DEEP CORE (3 X 1)
Deep Core is corrugated metal pipe which has a pitch of
three inches and a depth of one inch (see detail on this
page for definitions of pitch and depth). For larger
diameters, this corrugation profile allows the use of lighter
gauge material for any given loading condition and reduces
the weight and cost of corrugated metal pipe by 30% to
60%. The use of Deep Core provides economy and strength
in larger diameters. The standard length is 20 feet, although
other lengths are available. The available diameters range
from 42 inches to 144 inches. The available wall
thicknesses are .064 inches (16 gauge), .079 inches (14
gauge), .109 inches (12 gauge) and .138 inches (10
gauge).

SPIRAL RIB PIPE (SRP)
PACIFIC
®
CORRUGATED PIPE CO.
Spiral Rib Pipe (SRP) is one of many innovative pipe products developed by
Pacific Corrugated Pipe Company during it's long history in the drainage
industry. This exciting new product was developed in response to the needs
of drainage designers for a pipe product with the hydraulics of smoothwall
pipe plus the many other advantages of corrugated metal pipe.
Pacific Corrugated Pipe Company has developed a variety of rib profiles to
provide the widest range of sizes available in the industry. SRP is available
in sizes of 12 inches through 144 inches in steel and 12 inches through
120 inches in aluminum alloy.
Fabrication: SRP is a flexible metal conduit manufactured from a
continuous strip of galvanized steel, aluminized Type II steel, or aluminum
alloy. Available steel thicknesses are .064 inch, .079 inch, and .109 inch.
Available aluminum thicknesses are .060 inch, .075 inch, and .105 inch.
The coil strip is passed through a forming line which forms the ribs and
prepares the edges. The formed section is then helically wound into pipe
and the edges are joined by mechanical lockseaming.
Hydraulics: In 1983, a series of friction factor tests were conducted on SRP at the Utah Water Research Laboratory
located at Utah State University in Logan, Utah (Hydraulics Program Report No. 83). Tests were conducted on 24-inch
and 36-inch SRP with open ribs and 36-inch SRP with ribs filled. Comparison of the results with ribs filled to open ribs
showed little influence on flow due to the open rib section.

TriShield PIPE
TriShield steel ribbed polyethylene pipe is a state of the
art composite pipe product. It combines smooth wall
hydraulics and the structural strength of steel with the
corrosion and abrasion resistance of high performance
engineered polyethylenes.
At the core of the TriShield composite is a strong
galvanized steel sheet with 2 ounces of zinc coating per
®
square foot. Dow Trenchcoat protective film, 10 mil thick,
is bonded to the exterior side for protection from potential
soil-side corrosion.
TriShield pipe’s interior liner consists of a unique tie layer
film and a polyolefin plastomer liner, both developed by The
Dow Chemical Company specifically for this application.
This lining system has been thoroughly tested and found to
be highly resistant to a variety of chemicals and remarkably
resistant to scour and abrasion. It also exhibits excellent
adhesion and durability in handling and field service.
Hydraulics
TriShield pipe is not only tough and durable, but
demonstrates exceptional hydraulic efficiency as well. It is
suitable for use on storm drain, irrigation, small hydro, and
most other gravity water conveyance projects where
hydraulic efficiency and durability are design considerations.
TriShield pipe and pipe-arch are available in 30² through
108² diameters. Although 6² incremental sizing is
standard, 1² incremental sizes are available for specific
projects. Available steel wall thickness are .064², .079²,
and .109². TriShield is manufactured in accordance with
national specification ASTM A 978-97.
TriShield pipe can be made to the nearest diameter inch
of size required, within the available size range. With a
design Mannings “n” of 0.0105 and variable sizing,
TriShield pipe often allows designers to downsize a pipe
system from a standard incremental pipe size to the actual
size needed. This is particularly important when clearance
and flow capacities are critical.
Liner Integrity
The TriShield ribs are filled with extruded liner material and
slightly deltoided to provide a mechanical interlock between
the liner and the pipe wall. In addition, the liner is
chemically bonded to the pipe wall through an intermediate
adhesive tie layer. This dual attachment system provides
added assurance of composite integrity.

Polyethylene Lining
Using a Bed Load Abrasion Test Machine (ASTM A 926),
Samples of TriShield pipe were compared to samples of a
typical HPDE smooth wall pipe product. The test results
indicated that the TriShield polyethylene liner
outperformed HDPE (on the basis of weight loss) by more
than three and a half times.

Economic Benefits
TriShield pipe is premium pipe product that provides
notable strength, installation, and durability benefits. Its
light weight, long lengths, thinner walls, and variable sizing
result in significant savings in material, transportation,
handling, and installation costs. Get the full story in our

STRUCTURAL PLATE
PACIFIC
®
CORRUGATED PIPE CO.
Round
Structural plate structures, sometimes referred to as
sectional plate structures, have been used for many
purposes. In general, structural plate pipe (SPP) or
structural plate pipe-arch (SPPA) is used when the
maximum size of CSP or CSPA is exceeded or where
greater or differential thicknesses are required.
Structural plate pipe and pipe-arch are available in a
wide range of sizes. The minimum diameter of the
pipe is 5 feet and the maximum is 26 feet. The
minimum span x rise of the Pipe-Arch is 6 foot-1inch x
4 foot-7inch and the maximum is 20 foot-7 inch x 13
foot-2 inch. Structural plate structures are commonly
used in flood control, drainage and sewer systems.
They have also been used successfully for overhead
conveyor covers and passages; vehicular, pedestrian,
and animal underpasses; and storage bins. They have
also proven to be sound and economical structures in
many other applications.

FLASHBOARD RISERS
Flashboard risers are used to control water levels in ponds, settling basins, canals, and reservoirs.
They are also used as “turnouts” to redirect water from irrigation supply canals.
Short pieces of lumber are stacked in side channels to create a variable height overflow structure.
These structures are custom fabricated to meet specific project requirements. They are available in
a wide range of sizes and metal thicknesses, in steel or aluminum alloy.

SEPARATION, REINFORCEMENT, CONFINEMENT, &
FILTRATION. Common applications include stabilization of
parking and roadway structures; filtration in drainage
structures; construction of dams, levees, embankments,
and retaining walls; landfill covers and liners; and silt
fences. The full range of functions and applications are too
numerous to describe here. Contact Pacific Corrugated
Pipe Co. for additional information.

WITHOUT GEOTEXTILE
WITH GEOTEXTILE
The “pumping action” caused by repeated wheel loading
causes rock base and soil to intermix, weakening the
structural base. Without a solid base, the pavement flexes
and breaks up.
Geotextile prevents intermixing of soil and rock base,
retaining full rock section for maximum structural support.
Reduced rock requirements and lower maintenance costs
more than offset the cost of geotextile.

GENERAL INFORMATION
PACIFIC
®
CORRUGATED PIPE CO.
HANDLING
All pipe should be lifted off the trailer to avoid any damage
while unloading. Never allow pipe to be dragged off or
dropped from trailer height.
Pipe ends may be sharp. Handle with care.
Use gloves and other proper protective
clothing and equipment.
Slings should be used for lifting the pipe off the trailer and
for positioning pipes in the trench.
Safety Warning: Stack the pipe on the
trailer or ground with proper blocking or
strapping.
When unloading a nested pipe shipment, make sure that
the delivery site has ample room for unnesting the
various pipe sizes. Special care should be taken to avoid
damaging pipe while unnesting pipe.
Be careful when removing binders or
strapping on pipe bundles, either on the
trailer or ground. Never stand on pipe
bundles.
Unnest a pipe by using a two-by-four that is one to two
inches larger than the pipe’s inside diameter. Wedge it into
corrugation valleys and then pull on two-by-four with a
chain or wire rope.
BEDDING & BACKFILLING
Use well-graded compacted granular bedding or flowable fill material to one foot above the pipe. Trench
backfill should be free of rocks, frozen lumps, and foreign material that could cause hard spots or
decompose to create voids, compacted to 90% standard density per ASTM D698 (AASHTO T99).
Thoroughly tamp fill in max. 8² loose lifts. Keep fill at
same level on both sides of pipe.
Flowable fill.
Thoroughly tamp fill in max. 8² loose lifts. Keep fill
at same level on both sides of pipe-arches.

Compacted to maximum density under haunches
HEAVY CONSTRUCTION
For temporary construction vehicle loads (100 kips/axle load), put at least four feet of compacted cover
on top of the pipe (but not exceeding the maximum allowable cover over the pipe).
The use of heavy construction equipment
necessitates greater protection for the pipe than
finished grade cover minimums.
