What’s the casing pipe?

The shape of the casing section is round, in large diameter pipes and is inserted into the oil well, fixed with cement to protect other equipment that is mostly made of iron and steel. The oil well must be designed to withstand the force different from the external power, such as crushing, explosion, stress and chemical corruption. API 5CT casing pipe is used to support the oil and gas pipe wall, and to ensure the drilling process and the post-completion wells normal operation. Each well depending on the depth of drilling and geological conditions, to use several layers of casing. After cementing casing to be used to go down, it different from tubing, drill pipe and can not be reused, a one-time consumable materials. Therefore, the casing consumption accounts for over 70% of all the oil well pipe. According by usage can be divided into the sleeve pipe, surface casing, casing and production casing.

What’s the tubing pipe?

OCTG Tubing pipe goes inside the casing pipe because it is the pipe through which oil makes its way out. Tubing is the simplest part of OCTG and it is normally found in the segment of 30 ft (9 m), with threaded connection at both ends. The pipe is either used to transport natural gas or crude oil from the producing formation to the facilities where it will be processed after drilling is complete.Tubing (pumping pipe) goes inside the casing because it is the pipe through which oil makes its way out. Pipe of production is the simple part of OCTG and it is normally found in the segment of 30 ft (9 m), with threaded connection at both ends.
