Some Issues About OCTG Casing’s Transportation

The casing pipe is used to support oil and gas wall of the pipe, to ensure that the drilling and completion of the process of the normal operation of the wells. It depend on the drilling each well depth and geological conditions, to use several layers of casing.

Some Issues About OCTG Casing's Transportation

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.

Casing play an important role in drilling a well, so ensure the safe of the casings’ transportation is still important. Now I will introduce something about transportation.
1.Casing before loading and unloading, the inner and outer screw threads must be tightened by special tools.
2.The casing should be hoisted with nylon rope.
3.The pipe rack car or wagon should pad sleeper which cross section is 150mm×50mm. If the shipment is more than two layer, the sleeper shall be 300mm×60mm.
4.When casing loading, external thread or coupling should be installed one end of vehicles.
5.Casing vehicle is strictly prohibited overload, over high.
6.You should stop in time to prevent casing loosening and ensure safe transportation in transit.
7.Casing should be unloaded from the building root in turn. Control casing running speed, avoiding hit front casing when landing.
8.The number of loading casing can not more than 10 roots when using forklift and do it gently to avoid collision.
