5.23.14 Transportation and Storage

Lined equipment should be stored and transported with the following additional requirements. When lined pipe is transported by truck, a flatbed trailer should be used with at least three bolsters between each layer of pipe, with the bolsters aligned vertically above the previous layer to provide even support. The load should then be tied down to prevent any shifting, bending, or movement of the pipe. All pipe should be transported with closed-end thread protectors on both ends, preferably made of plastic or plastic-lined steel (composite).

For storage, the pipe should be placed on at least three racks or wooden sills evenly spaced to keep it around 48 cm off the ground. To stack the pipe, wooden bolsters should be placed between each layer, directly above the pipe racks, with each layer being blocked to prevent shifting. When movement of the pipe is required on the racks, bars or similar objects should never be placed in the pipe’s inside diameter (ID). If thread protectors come loose, the threads and lining should be inspected for damage, and the thread protector reinstalled prior to any movement.

When running the pipe, it is important to select the best tools available, especially slips, power tongs, backup tongs, and slip-grip elevators. Equipment with as much surface contact as possible to the pipe (e.g., full wraparound tongs) should be used. When the tubing is lifted onto the rig floor, the pin-end thread protector must be in place to protect the threads and lining that covers the chamfer and (typically) the first two threads. It is removed just prior to stabbing for makeup.
