4) Specified Wall Thickness
The wall thickness and structural design is the responsibility of the purchaser. The purchaser shall
specify the wall thickness required for his project as required by his design calculations, applicable

thicker wall thickness shall be specified by the purchaser if needed to meet his requirements.
Round Pipe:
The minimum specified wall to be used for round pipe made to this specification shall be .500 nominal
wall, and the wall thickness at any one point shall not be more than 12.5% under the specified
nominal wall thickness. (ie. Min wall = .875 x specified wall thickness)
Page 11
INFRASTEEL 242 (dtd 3-14-14)
Elliptical Pipe, Arch Pipe, and other non round pipe sections:
The minimum specified wall thickness to be used for these sections shall be .500”, and the wall
thickness at any point shall not be thinner than .015” under the specified wall thickness. (ie Min wall =
specified wall thickness minus .015”)
5) Chemical Composition
Each heat number of steel used for this product shall be tested for chemistry and shall conform to the
following:
Carbon:
Manganese:
Phosphorus:
Sulfur:
Copper:
.26 max
1.65 max (see note below)
.035 max
.035 max
.20 min
Note: For each reduction of .01% carbon below the specified maximum concentration of carbon given above, an increase
of .05% over the specified maximum concentration of manganese given above is permissible up to a maximum of 2.00%
manganese.
6) Tensile Requirements for the Steel
Tensile strength: 60000 psi min.
Yield strength: 36000 psi min.
Each heat number used shall be tested for tensile and yield strength, and the results must meet the
tensile and yield requirements above.
At the option of the purchaser, the Tensile test may be done on only one random sample taken from
each 100 ft. of each pipe size on each purchase order and must meet the above tensile and yield
requirements.
7) Test Report Requirements
A Pipe Material Test Report shall be furnished by the pipe mill producing the pipe.
The Pipe MTR shall provide the chemical test results of each heat number used in each pipe for the
elements listed in section 5 above. Chemical test results must conform to section 5 of this
specification.
The Pipe MTR shall also provide tensile and yield properties for each heat number used in each pipe;
or if the purchaser specifies random sampling for tensile testing in accordance with section 2.6 of this
specification, the Pipe MTR will show random tensile test results as required by section 2.6 of this
specification. The tensile test results shall conform to section 6 of this specification.
All pipe must be manufactured in the USA.
All pipe must be made from steel plates that were produced in the USA, and the Pipe Material Test
Report shall certify that pipe was made from domestic steel.
If MMU pipe is specified by the purchaser, all plates used shall be “melted and manufactured in the
USA”, and the Pipe Material Test Report will list all of the heat numbers or plate id numbers used for
each pipe and will certify that pipe was “melted and manufactured in USA”. Back up papers from the
plate mill will be supplied to show that the plate was “melted and manufactured in the USA”.

INFRASTEEL 242 (dtd 3-14-14)
8) Pipe Dimensional Tolerances
8.1 Length: The length of each pipe shall be within +-1/2” of the specified ordered length.
8.2 Circumference: The outside circumference at any point in the length of the pipe shall be
within 1% of the nominal circumference or within +-1/2”, whichever is less.
8.3 Straightness: The maximum allowable straightness deviation in any 10 ft length shall be 1/8”.
For lengths over 10 ft the maximum deviation of the entire length may be equal to [1/8” x (total
length in ft/10 ft)].
8.4 Roundness (for round pipe sections): The difference between the major and minor outside
diameters at each end of each pipe shall not exceed ¼” for diameters up to and including 48”
OD and ½” for diameters greater than 48” OD.
8.5 Wall Thickness:
Round Pipe: For round pipe sections the minimum wall thickness at any point shall be not less
than
12.5% of the specified wall thickness.
Elliptical, Arch Pipe, and other non round sections: For Elliptical, Arch Pipe, and other non
round
sections, the minimum wall thickness at any point shall not be less than .015” below the
specified wall
thickness.
9) Ends
Pipe ends shall be square cut or shall have a 30 degree bevel on OD or ID as specified by purchaser.

InfraSteel Installation Guide

Begin by tack welding the pipe, starting on the bottom, every 6 inches once it is aligned. The
welders should work from the bottom of the pipe, working upwards to the top. Porta Power
tools, wedges and modified C clamps may be required to manipulate the steel for alignment.

The bracing inside of the liner should be used as a visual tool to aid in alignment; think of
aligning the crosshairs of a scope when setting the piece into position. When welding one
piece to another piece use the longitudinal weld seams in the haunches, where the bottom half
is welded to the top half, for alignment. There is also a mark at 12:00 and 6:00 center on each
piece for alignment.

Ears or Tabs may be welded on the top of one piece so it can be hung on the next piece while
they are being aligned.

The bottom of each piece has an inverted bevel so it can be welded from the inside. This
allows for less excavation of the streambed and keeps the welder from working under the pipe
on his back.

Grout Ports should be added every 10’ at 12:00 center. As grout is being pumped into the
downstream end the grout will fill up the annular space moving up hill. As the grout moves
uphill the next grout port will be used as a vent to indicate how far up the grout has moved, and
should be plugged when grout reaches it. Additional grout ports should be used as needed and
can be added anywhere that grout is needed to fill voids.

The bracing inside of the pipe should not be removed until the grouting process is completed.

The lead piece of pipe may be tapered inward as necessary; with longitudinal cuts 3” to 4” long
every 6 inches, to facilitate the slip lining process. Also tracks may be welded to the bottom of
the host pipe to facilitate the slip lining process.

Arched pipe with a flat bottom is more prone to float when grout is being pumped than pipe
with a radius on the bottom. If necessary spacers may be added to keep the liner from floating,
prior to grouting, by cutting a hole in the top of the pipe, and welding in a steel spacer that runs
from the top of the liner to the ID of the host pipe structure.
Limited Warranty: Infrasteel is manufactured for each specific purchase and is warranted only to the extent that it is
proven to be defective in material or workmanship prior to installation. Damage due to installation or grouting is not
warranted. If the product is deemed defective, the purchaser should provide immediate written notice of the defect and
provide an opportunity for inspection by an Infrasteel representative. The InfraSteel product will be repaired on site,
repaired at the plant, or replaced at Infrasteel’s discretion, to the satisfaction of the purchaser.
