6.2

Anti-Galling Plating For API 8RD or Buttress Connections, the threads of coupling shall be phosphated with Zinc, Manganese, Tin or phosphate plating (the whole coupling can be dipped). Neither pin end has to be phosphated but can be if the manufacturer so chooses. For L80-13CR, only the threads of coupling shall have a copper over nickel plating. Pins shall be bare. For Premium Connections, the anti-galling plating shall be applied in accordance with the patent holder’s specifications in regard to type and location.

6.3

Hydrostatic Pressure Rating For API 8RD or Buttress threaded and coupled connections, the hydrostatic pressure test shall be performed in accordance with API SPEC 5CT with the couplings installed power tight using API Modified Thread Compound with friction correction factor of 1.0 in accordance with API BULL 5A3. As alternative method to the above, a)

The hydrostatic test may be performed on two phase hydrotest with the pipe tested in plain end condition and then an end area hydrotest performed on the coupling end after coupling made up.

b)

The plain pipe may be hydrotested, providing no further heat treatment is required. The coupling is made up to the pipe performing power tight thread make up using API Modified Thread Compound with friction correction factor of 1.0 in accordance with API BULL 5A3 using a computer analyzed torque-turn system for each joint to control and verify the correct torque values during coupling make up (and where applicable) the shape of the torque turn graph. A visual torque graph shall be kept (both in hard copy and digital format) for each joint which provides the thread make up details and final torque applied.

For Premium Grades and Premium Connections, the hydrostatic test shall be performed on plain end conditions for both the pipe and the coupling stock, providing no further heat treatment is required. Then, the vendor or the end finisher must perform a power tight thread make up using API Modified Thread Compound with friction correction factor of 1.0 in accordance with API BULL 5A3 (if thread is not dopeless type) using a computer analyzed torque-turn system for each joint to control and verify the correct torque values during coupling make up (and where applicable) the shape of the torque turn graph. A visual torque graph shall be kept (both in hard copy and digital format) for each joint which provides the thread make up details and final torque applied.

Delivery from Port and In Kingdom Facilities to Saudi Aramco Storage Yards To minimize the number of trucks required, to promote safe transportation and loading/unloading, and to reduce transit damage; shipments of OCTG handled by the Local Agent and delivered direct to Saudi Aramco storage yards, shall have dunnage under the bottom row and between each subsequent row of pipe. A row is defined as a layer of pipe if 5” or larger when laid in singles, and a layer of bundles when 4-½" and smaller pipe is shipped. The dunnage shall be a minimum of 1-½ inches thick and can be of any width strong enough to support the load. The length shall extend to the side posts but does not have to be a single piece to span the gap. The wood dunnage does not have to be new and can be returned by the driver. For Range-2 pipe (AVG=30 FT), a minimum of 3 pieces of wood per row must be used ( 1 near each end and 1 in the middle ). For Range-3 pipe, a minimum of 4 pieces of wood must be used ( 1 near each end and the other 2 equally spaced in between ). 30” pipe with length of 55-60 feet must be shipped on a special truck to accommodate the length with proper support distribution, and with one row of pipe. The truck shall have steel side posts sufficient to hold the load and tall enough to extend beyond the height of the top row with a minimum of 3 hold down chains or straps to secure the load. The Local Agent should arrange for direct delivery off the boat to avoid the extra handling in the lay down area.

Pipes shipped loose must all be in direct contact with the dunnage supporting it and not laying on other pipes beside it. Dunnage must not be placed under coupling or the upset part of the pipe. Longer pipe such as 30” with 55-60 feet long shall be loaded and shipped on special extended trucks with minimum 4 rows of dunnages having equal distance with no pipe ends extending outside the truck bed to avoid any pipe span. For High and corrosion resistant alloy such as super 13 Chrome, UNS N08028, etc. Pipes must be shipped in pipe packing system. Approved systems are TGT- Pipe Packaging and DrillTech-RAP packaging systems. External coated casing, tubing and pie must be shipped on truck equipped with rubber to avoid direct contact between the pipe coating external body and the truck bed support. Pipes shall be protected with rubber or rope ring for handling and to provide enough room when shipped in more than one layer. Non coated plain end pipe that requires further processes can be shipped in staggered pattern.
