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.


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.
