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 Richard L. Beam Associate Director for Pipeline Safety Regulation Materials Transportation Bureau <<>> Ameron 595 West Lambert Road Post Office Box 1010 Brea, California 92621 November 30, 1982 Mr. Richard Beam Associate Director Office of Pipeline Safety Regulations Material Transportation Bureau 400 - 7th St. S.W. Washington, D.C. 20590 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.

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 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.
