The specimens shall be oriented transverse to the length of the pipe. They shall be full size or as large a size as possible and they shall be notched through the thickness. The specimens and testing procedure shall be in accordance with ASTM E 23. The minimum average energy absorbed per set of three specimens shall be 35 ft lbs. No specimen shall exhibit less than 60% percent shear area on its fracture surfaces. Should any test fail, the retest procedure shall be the same as that described in Supplementary Requirement SR5 of API Spec 5L. 6.3 HYDROSTATIC TESTS Each length of pipe manufactured shall be hydrostatically tested to a minimum pressure equal to 90 percent of the Specified Minimum Yield Strength (SMYS) of the pipe for a minimum duration of 10 seconds. All other requirements of API Spec 5L regarding hydrostatic testing of steel line pipe shall apply. All hydrostatic tests shall be recorded with a calibrated chart recorder. Under no circumstances shall distorted pipe be shipped to the COMPANY At the beginning of production and at least once during the production of this pipe, the Vendor shall remove the hydrostatic pressure gauge and verify calibration using a deadweight tester or a calibrated master gauge. Pressure gauges used in hydrostatic testing shall preferably have dials graduated over a range of about double the intended maximum test pressure but in no case shall the range be less than one and one half (1.5) nor than three (3.0) times that pressure. 7. DIMENSIONAL AND ACCEPTABILITY STANDARDS 7.1 Outside diameter of the pipe shall meet the minimum tolerances specified in Section 6, Paragraph 6.2 and Table 6.3, of API Spec 5L. 7.2 The wall thickness at any location on each pipe shall meet the minimum tolerances specified in Section 6, Paragraph 6.3, of API Spec 5L. Wall thickness tolerances of +10% / 10% shall be satisfied in lieu of the values shown in Table 6.3 of API Spec 5L. The remaining wall thickness in grind areas shall be a minimum of 90 percent of the nominal wall thickness. The wall thickness at both ends of each pipe shall be measured for conformance to this requirement. As an alternate, Vendor should also supply cost impact to reduce wall thickness tolerance to ±5%. If the wall thickness at any point is less than 90% (95% if ±5% is selected) of the specified pipe wall thickness, it is classified as a defect. The above wall thickness requirement is applicable to the remaining wall thickness caused by either linear or non linear imperfections. A compression wave ultrasonic unit shall be readily available to mill inspection personnel in order to determine the remaining wall thickness of defect areas. 7.3 Each length of pipe shall be weighed separately, and carload weights determined in accordance with Section 6, Paragraph 6.4, of API Spec 5L. The results shall meet the minimum tolerance set forth in Table 6.3 of API Spec 5L. The total weight of each carload shall be within +5% in addition to API 5L limit of 1.75% of the weight calculated based on nominal pipe wall thickness. Specification for Heating Pipe 7 of 17

8 Each length (or joint) of pipe shall be weighed to an accuracy of ±0.5%. The weighing equipment shall be calibrated at intervals to be agreed between Manufacturer and Purchaser. As a minimum, weighing equipment shall be calibrated at the beginning and completion of each shift. The length of each pipe joint shall be measured to an accuracy of 0.1 foot. Manufacturer shall provide a tally of pipe joints with joint number, measured joint length and measured joint weight in a spread sheet in hard copy and computer diskette in Lotus or Exel. 7.4 Pipe shall be furnished in double random lengths with an average length of 40 feet. No lengths shall exceed 43 feet or be less than 37 feet. The use of short spliced joints shall not be permitted. As an alternate, Vendor shall provide quote to furnish pipe with the length tolerance reduced such that no length exceeds 41 feet and no length is less than 39 feet. 7.5 Deviation from a straight line in any portion of a pipe joint shall not exceed 0.15 percent of the length of that pipe joint. 7.6 Pipe ends shall be beveled in accordance with Section 7.3 of API Spec 5L and shall be square within 1/16 inch, measured not less than three times per working shift. If a pipe fails to meet the requirements of the end squareness test the testing shall be increased to hourly. The frequency may revert back to original when four (4) consecutive satisfactory measurements are made. Special attention shall be given to ensure that the deviation from the required root face of 1/16 inch at the beveled ends is kept to a minimum within the specified tolerance of plus or minus 1/32 inch. If the root face is less than 1/32 inch, it shall not be brought into tolerance by filing or grinding; the entire bevel shall be remachined. After beveling, protectors shall be provided and must be in place during any subsequent pipe movement. 8. WORKMANSHIP 8.1 GENERAL The pipe shall meet all of API Spec 5L for workmanship, visual inspection and repair of defects. Any imperfections having a depth greater than 10% of the specified nominal wall thickness, measured from the surface of the pipe, shall be considered a defect and unacceptable COMPANY may wish to be represented at the mill by an agent who will be responsible for overseeing the inspection of the pipe and determining the general quality. In such instances, inspection notices shall be sent to COMPANY and its agent giving the time at which production will begin at least 10 days prior to production If the rejection rate during production exceeds 5 percent, COMPANY shall be entitled to refuse acceptance of production until the cause thereof is rectified Repair welding to the parent metal shall not be permitted Dents shall not be removed mechanically. Dents of 1/16 inch or more in depth that contain gouges, grooves or scratches shall be removed by cutting out a piece of pipe in the form of a cylinder The pipe surface shall be free from all surface laminations, seams or laps Defect removal shall be by grinding. All grinding or filing marks made on the pipe shall be properly blended out All hammering of pipe and dropping onto steel rails is prohibited. Specification for Heating Pipe 8 of 17
