This document provides information and guidelines for receiving, inspecting, handling, storing, transporting, and stringing pipe. It discusses verifying documentation during receiving, inspecting for material grade, diameter, thickness, and specifications. It outlines requirements for proper handling including using padding and slings to prevent coating damage during transportation, storage, and stringing. Specific separation requirements are defined for stacked coated pipes. Receiving inspections include verifying markings and ensuring freedom from defects.

7. WHAT IS THE MEANING OF HEAT
NUMBER?
• Heat : The metal produced by a single cycle of a
batch melting process.
• Heat Number : An identifying number assigned
to the product of one melting in an electric arc
furnace: e.g. 1204232. Sometimes, but not
universally, the first digit indicates the furnace
number; the second digit indicates the year in
which the heat was melted. The last three (and
sometimes four or five) digits show that this
was the 04232th heat melted in No. 1 furnace
during 2012.

8. STORAGE, HANDLING AND
TRANSPORTATION
• The coated pipe shall be handled at all times in a manner
that prevents damage to the pipe walls, beveled ends, and to
the coating (including internal coatings, if applied).
• All equipment, including field bending machines and pipe
cradles, that contact the coated surface of the pipe shall be
padded. Slings shall be nylon or equivalent; steel cables shall
not be used.
• Coated pipes shall not be rolled or dragged on the ground.
Coated pipes shall be protected by wrapping polyethylene
strings near the pipe ends.
• During storage the coated pipes shall be placed at least 150
mm off the ground on either rock-free sand berms covered
with polyethylene sheeting or on padded skids spaced and
leveled so that the pipes are supported without damaging the
coating.

9. CONTINUE:
• FBE-coated pipes shall not be stacked directly
against each other at any time during storage or
transportation. They shall be separated by full
encirclement, non compressible rubber padding
or equivalent at least 10 mm thick.
• Twelve meter (12 m) joints of pipe shall have at
least 3 full encirclement separation pads. Two (2)
shall be located 1 to 3 m from each end of the pipe
and 1 in the middle.
• Twenty four meter (24 m) double-jointed pipe
lengths shall have at least 5 full encirclement
separation pads placed so that 2 of them are 1 to
3 m from the outer ends of the pipe and 3 of them
support the center section of the pipe. Placement
of the pads should be approximately equidistant
from each other.

10. CONTINUE:
• Truck beds and sides shall be inspected to
ensure that there are no projections (rivet
heads etc.) that may cause fretting during
transportation.
• Wooden bearing strips shall be used.
• Pipe layers must be separated by wooden
separators or by rubber sheet, at least 6 mm
in thickness or by nylon ropes having a
minimum diameter of 19 mm.
• The packing list for transportation must
include the pipe numbers, relative location
in the truck and the truck number on which
specific pipes are being transported.

14. STRINGING REQUIREMENTS
• Externally coated line pipe string along the right-
of-way shall be supported on rock-free sand, sand
bags, rubber tires, or similar compressible
material to prevent coating damage. (See also the
general handling requirements in Paragraph
5.1.)
• Coated pipe is handled with soft slings (nylon or
equivalent) and padded supports at all times.
• Slings for lifting pipe shall be nylon or similar
material to prevent damage to the pipe surface.
Wire rope slings shall not be used.

15. RECEIVING INSPECTION
• Marking on the pipe and on tags, confirmed with the
material description on the P.O. and the physical
properties of the pipe material in terms of the
following:
1. Material type / classification / grade
and class
2.Diameter
3.Thickness or Pipe schedule
( API Spec 5L. Para. 10.3 & 10.4)

17. CONTINUE:
• Each pipe shall be marked Saudi Aramco,
followed by the destination, Purchase
Order number/Item Number, heat
number,
• Surface of the pipe that will be coated
shall be essentially free of scabs, slivers ,
cold laps, burrs or other surface defects
that would impair the coating.
• Pipe has no OD or ID surface imperfection
that has a depth greater than 12.5% of
the the specified wall thickness.

18. CONTINUE:
• The pipe shall contain no dents greater than
¼ inch (6.4mm).
• Pipe has no cold-formed dents deeper than
1/8 inch (3.2mm).
• Pipe(s) free from following physical defects:
a. Cracks (all)
b. Lamination or inclusion
c. Arc Burns
d. Undercuts
e. Under fill

19. CONTINUE:
• Pipe that is to be joined using pipeline Automatic
Welding System is designated in the Purchase Order
as “Suitable for AUTOMATIC WELDING” shall meet
the following additional requirements:
1. Straight seam or spiral welded pipe, outside weld
reinforcement shall be ground flush with the pipe
surface for a minimum longitudinal distance of 130
mm from each end of the pipe
2. The difference in outside diameter, at the ends,
between any two lengths of the same line item shall
not exceed 1.6 mm for 75% of the pipes produced.

20. CONTINUE:
3. Out of Roundness at the ends shall not exceed
max or min 0.5% of the specified OD. For pipe with
D/t<75, the difference between maximum &
minimum diameters shall not exceed 6 mm.
4. On SAW pipe for automatic welding , local out
of roundness in the form of seam shall not
exceed 1.6 mm.
*Tolerance = now 1% per January 2007 Edition of
01-SAMSS-035.
