API Casing:

API Casing is a wide range pipe that serves as the structural retainer for the walls of oil and gas wells or well bore. Casing inserted into a good bore and cemented in place that to protect it. In case the subsurface formations or well bore collapse. The casing will allow drilling fluid to circulate and extraction to take place.

 

Oil Tubing:

Tubing is a pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete.

Oil tubing will bear the pressure generated from the extraction process. The manufacturing process is the same as the casing. But the most different point is to use an additional process "upsetting". That is applied to thicken the pipe.

 

API Coupling:

Couplings are short lengths of pipe used to connect 2 joints of tubing or casing. It comes with a painted color code on their external surface to indicate their grade. The steel coupling is mainly used to connect oil pipes in oil drilling. This product can be used to connect the shaft of units that are manufactured separately.

 

Drill Pipe:

The drill pipe is a hollow, thin-walled, steel or aluminum alloy pipe used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It is made up of three separate pieces: the box tool joint, the pin tool joint, and the tube.
