Mr. Kenneth J. Dooley District Sales Manager Ameron
Corrosion Resistant Piping Division
596 West Lambert Road
Brea, California 92621
Dear Mr. Dooley:
This refers to your letter of November 30, 1982, requesting our approval of Ameron RTR pipe for use
in pipelines that are subject to 49 CFR Part 195.
The Part 195 safety standards for hazardous liquid pipelines do not prohibit the use of pipe made
of materials other than steel. Thus, a special approval or waiver is not required for the use of
such materials. However, as more fully stated in §195.8, the use of any material other than steel
in a proposed pipeline is conditioned upon the operator of the proposed pipeline giving prior
notice to this agency so that a determination can be made about the safety of the pipeline before
transportation begins. A separate notice must be given for each pipeline that is to be constructed
of a material other than steel.
The letter you have sent to us does not meet the notice requirements of §195.8; thus, we will not
begin any action under that section until proper notice is received from the operator.
Sincerely,
Original signed by

Dear Mr. Beam:
Long Beach Oil Developers, Long Beach, California
Pipeline Safety Regulations - Hazardous Liquids, Section 195
The above subject covers the transporting of oily water. The water content as I understand it, is
in excess of
95% and less than 5% oil.
The Long Beach Oil Developers are contemplating the replacement of steel mortar lined pipe because
of continuing corrosion in the lines with resultant leaks. In addition to the corrosive leaks,
there is a combination of corrosion and erosion causing a build up on the inside diameter and
eventual clogging of the line.
I am enclosing literature on the Ameron Bondstrande® RTR Pipe which will be corrosion free on both
the inside and outside diameter. Being corrosion free, you will have a product that will not leak
or clog due to the effects of corrosion and erosion.
I am also attaching copies of:
A) Mil Spec P-22245A - Condensate and Jet Fuel
B) Mil Spec P-28584 - Condensate
C) Jet Fuel Case Histories
D) U.S. Government Users List
The conditions of the pipe line are 160°F with a 200 psi working pressure. We would furnish a 14
Bar (205 psi) piping system with a 4 to 1 safety factor. The pipe is buried in 3 to 4 feet of earth
cover and is extremely strong and resistant to external loading. I am attaching a picture on 12"
pipe where we have subjected the pipe to a tractor running over it.
I would appreciate your approval for Ameron RTR pipe in this type of service by your permitting a
waiver at this time and eventually granting permission. It is a definite advantage over the steel
pipe.
I thank you for your help and cooperation. Very truly yours,
Kenneth J. Dool
District Sales Manager

surfaces not smooth and uniform, and
identification marking incorrect or missing.
4.3.1.1 Dimensions. Compliance with dimensional requirements shall be determined by the following
methods of measuring.
4.3.1.1.1 Wall thickness. The wall thickness shall be measured with a spring-loaded dial caliper or
screw micrometer equipped with an inner anvil with a radius substantially smaller than the radius
of the inside of the pipe. Four measurements shall be made at the open end of each sample and four
measurements on each of six sections cut
along its length to show consistency of wall thickness throughout the length.
4.3.1.1.2 Outside diameter. The outside diameter shall be measured with a flat anvil micrometer or
vernier caliper capable of reading in 0.001 inch increments. The same number of measurements as
required for the wall thickness measurements shall be made using the same wall thickness samples.
4.3.1.1.3 Out-of-roundness. The out-of-roundness shall be determined by the fit of a "go-no go"
gage.
4.3.1.1.4 Other dimensions. Dimensions other than those above shall be measured in accordance with
standard practices.
4.3.2 Tests. Tests which are specified at "roan temperature" are to be accomplished under normal
roam conditions with the temperature not to be below 65 degrees F. This will allow testing to be
done in areas which do not have close roam temperature control. Tests shall not be accomplished in
areas of abnormally high or low humidities.
4.3.2.1 Potable service data. To qualify pipe, fittings, and adhesives for potable service, the
manufacturer shall submit to the Bureau of Yards and Docks for approval all pertinent data
supporting potable service acceptability, including extraction study details and results, and a
list of the materials, with their chemical and trade names, used in the manufacturing process.
4.3.2.2 Beam deflection. A minimum 6 foot length of pipe shall be capped and filled completely with
water but not pressurized. The pipe shall be suspended by laying the end caps on appropriate
supports, allowing the pipe to hang free between the supports, and supporting the end caps at their
centers of gravity. Type I and Type II pipe shall be tested with water at 120 degrees F. Type III
pipe shall be tested with water at 200 degrees F. The sag in the pipe shall be measured and
recorded every 168 hours for a period of
1008 hours plus or minus 8 hours. The sag at. the end of the test shall be used to calculate the
value of E in the formula:
Y = 22.5 W L4
El
Where I = p (D4 – D14).

4.3.2.3 Expansion and creep. A minimum 6 foot length of pipe shall be capped or plugged and filled
completely with fresh water containing a soluble fluorescent dye. The pipe shall be laid on lightly
greased, 1/2 inch wide steel bars spaced every 2 feet, with the top of the bars on one horizontal,
plane. The ends of the pipe shall be unrestrained. The pipe shall be equipped with gages for
measuring circumferential and axial expansion and creep of the pipe. Micrometer gages, strain gages
(SR-4 type), or equivalent extensometer having an accuracy of 0.000] inch shall be applied in three
locations. Two of these gages shall be mounted so as to indicate circumferential expansion, the
other to indicate axial expansion. The circumference and length of the pipe shall be recorded
before, during, and after pressurization. Hydrostatic pressure at 1-1/2 times the psi for the top
bracket of its class shall be maintained at room temperature for a minim= of 2000 hours. Readings
shall be recorded to the nearest 0.001 inch. Sufficient readings (maximum 96 hour intervals) shall
be taken during the test to provide a significant data plot. At the end of the 2000 hour period,
while the sample
is still under pressure, it shall be examined for porosity, distortion, and structural failure. In
this and other tests where examination for porosity is made, the detection of small amounts of
weeping shall be accomplished by viewing the samples in a darkened area with a suitable
ultra-violet lamp such that a droplet of water containing the fluorescent dye will glow brightly
and be easily detectable. After completion of the examinations, the pressure shall be released and
readings recorded until they show no further change in pipe dimensions.
4.3.2.3.1 The above procedure shall be repeated on separate samples with the internal water
temperature at 150 degrees F for Type II and Type III pipes and at 1-1/2 times the psi pressure for
the top bracket of its class.
4.3.2.4 Cycling. At the termination of the expansion and creep test (4.3.2.3 and 4.3.2.3.1), the
samples shall be held at room temperature and cycled between 0 and 1-1/2 times the psi for the top
bracket of its class for 10,000 cycles. Approximately 7 seconds time shall be used to amply the
pressure followed by a 30 second dwell at full pressure, and then immediate removal of the pressure
followed by 30 second dwell at zero pressure. At the end of this cycling test, the samples shall be
allowed to remain pressurized at 1-1/2 times the psi for the top bracket of its class for 2 hours,
at the end of which time the samples shall be examined for porosity with an ultra-violet lamp and
for structural failure.
4.3.2.5 Impact resistance.
4.3.2.5.1 Pipe. A steel ball 2 inches in diameter and weighing approximately 1-1/4 pounds shall be
dropped squarely onto the surface of the pipe with a free fall (which may be guided) for a distance
of 1 foot. The ball may be caught or deflected after the hit so that the rebound does not hit the
pipe. The pipe shall be full of water containing a soluble fluorescent dye but not pressurized. The
test shall be made at room temperature and the pipe shall be supported on its bottom axis on a
solid flat support. Four drops shall be made on randomly selected areas which are a minimum of 12
inches and 90 degrees clockwise from each other. The test shall be repeated on the same pipe but
with the pipe pressurized at the maximum service pressure. Four drops shall be made on different
areas from those previously used. The pipe shall then be pressurized to 1-1/2 times the psi for the
top bracket of its class and shall remain at this pressure for 168 hours at the end of which time
the pipe shall be examined for porosity with an ultraviolet lamp.
4.3.2.5.2 Fittings. Fittings shall be tested following the above procedure except that the drops
shall be reduced from four to one in each test.
4.3.2.6 Delamination resistance. A 2-1/2 inch long sample shall be cut at least 4 inches from the
end of a length of pipe and tested in the fixture shown in Figure 1. The sample shall be tested at
room temperature Under 500 psi hydrostatic pressure for 168 hours. No oil or other foreign material
shall be on the sample or
in the water. At the end of the test period, the sample shall be examined for indications of
delamination or porosity (through outside wall, inside wall, or the non-exposed edge).
4.3.2.7 Boil resistance. Three test samples, 1-1/2 inches in length, shall be cut from a length of
Type Ill pipe. The samples shall be taken from sections at least 6 feet apart along the length of
the pipe. Type III fittings shall be tested using either the whole fitting as the test sample or
three 1-1/2 inch lengths cut from the fitting. The samples shall be conditioned for 8 hours at 300
degrees F., desiccated, and an initial weighing made. The samples shall then be suspended in a
boiling distilled water bath for 3 hours. The samples shall then be removed one at a time, blotted
dry of excess water, and weighed. This weighing shall be made
within 1 ± 0.5 minute after removal from the bath. After weighing, the samples shall be visually
examined for delamination or other evidence of impairment and the percentage weight gain of the
samples shall be calculated as follows:
% weight gain = B —A X 100
A
Where A = initial weight
B = weight after immersion
43.2.8 Joint strength. Two pieces of pipe shall be cut so that when they are joined together with a
compatible coupling, the overall length shall be 18 inches or 7 times the outside diameter,
whichever is greater. The pipe shall be cut so that the coupling is within 1 inch of the center of
the completed test section. Unthreaded joint assemblies shall be made with an adhesive as
recommended by the manufacturer and shall be applied and cured as under field conditions in
accordance with his printed instructions. The test section shall be subjected to a hydrostatic
pressure of 1-1/2 times the psi for the top bracket of its class for 168 hours at 150 degrees F.
for Type I, 200 degrees F. for Type II, and 300 degrees F. for Type Ill pipe and coupling. The
liquid medium shall contain a soluble fluorescent dye and may be oil or water. Observations shall
be made each 24 hours for porosity (using an ultra-violet lamp) or other evidence of failure of the
pipe, coupling, or joint. If the test section is not defective at the conclusion of the 168 hours,
it shall be tested to failure by subjecting it to the short-time burst test (43.2.9) at the maximum
service temperature for the Type. The test report shall include the time to failure, type of
failure, and the psi at which failure occurs.
4.3.2.9 Short-time burst. Three samples shall be cut from a length of pipe. The length of each
sample shall be 18 inches or 7 times the outside diameter, whichever is the greater. The test shall
be made using an appropriate sealing plug in each end which are restrained by a holding frame or
rod so that loading is pat on the pipe. The pipe sample shall be pressurized at an approximate rate
of 1000 psig per minute. If the pipe circumference expands beyond the capacity of the sealing
mechanism to hold pressure, collett-like holding bands may be used over the outside of the pipe
over the sealing area to prevent excessive expansion. The pipe failures must occur away from these
bands and in the central area of the pipe to be valid. The test shall be run at roan temperature,
and the sample shall be tested to failure. A failure is defined as porosity, horizontal
splits, delaminations, bursts, or other defects which permit the transmission of the test fluid to
the outside
surface of the pipe. The test report shall include the time to failure, type and location of
failure, and the psig at which failure occurs for each of the three samples.
43.2.10 Specific gravity. Five samples selected from various sections of the pipe or fitting shall
be tested in accordance with Method 5011 of Federal Test Method Standard No. 406.
4.3.2.11 Resin content. Five samples selected from various sections of the pipe or fitting shall be
tested in accordance with Method T061 of Federal Test Method Standard No. 406.
4.3.2.12 Hardness. The hardness of pipe and fittings shall be determined with a Rockwell Hardness
Tester in accordance with Method 1081 of Federal Test Method Standard No. 406. A V-notch anvil
shall be used for cylindrical specimens.
4.3.2.13 Burning rate. The burning rate of the pipe shall be determined in accordance with Method
2021
of Federal Test Method Standard No. 406.
