OCTG stands for oil country tubular goods. This is a large family that comprises of different products and among them is the OCTG tubing. Others in this family include the drill pipe and steel casing.
If you are in the oil extraction industry, an OCTG tubing is just one of the must-have equipment for the oilfield. It plays an important role during the oil recovery process.
Are you planning to buy OCTG tubing in China? Spare a few minutes to read this guide. You will learn some of the things that will help you buy this oilfield equipment in China.

What is OCTG Tubing?
So, what is OCTG tubing? This is a tubular good through which oil and gas flow through from the wellbore to the surface.
The tubing is usually located inside an OCTG casing since it is the one that will come into direct contact with the oil and gas.
An OCTG tubing comprises several connections that end up forming several segments at intervals of 3 ft or 9 meters. The connection must be strong and flawless so that it can form one seamless tube.
A typical OCTG tubing must be strong enough to withstand the high pressure of oil that is flowing through it. The strength also plays a role in preventing breakage or deformation of the tube during the oil extraction process.
Functions of OCTG Tubing
As we have just mentioned, the primary goal of OCTG tubing is to direct oil and gas from the well to the surface. Without this, it will be quite difficult to control the direction of the extracted oil.
Do you know that quality OCTG tubing can help to preserve the state of an oil well? Circulating oil and gas have high pressure and if they are not directed in the right direction, they can make the well to collapse.
OCTG tubing plays an important role in artificial lifting methods. These techniques entail the application of external forces to push oil from the well to the surface.
Given the positioning of the tubing(beneath the casing) it protects the case from corrosion and abrasion that is caused during the process of oil extraction. They are strong enough to withstand such forces without undergoing any physical or structural damage.
From these reasons, it is clear that you cannot avoid using OCTG tubing in your oilfield.
Most government and regulatory bodies require that oil extraction companies use tubing. Special permission must be obtained in case you are planning to avoid using OCTG for oil and gas extraction.
Selecting OCTG Tubing for Oil Recovery
When it comes to buying OCTG tubing in China, it is quite imperative that you will go for the best.
However, what may be good for a particular oilfield may not be ideal for you. This is because the tubing tends to vary so you need to dig deep and find out which one will be the best for your wellbore.
A proper OCTG tubing design and dimensions will determine the overall well-being, performance, and safety of an oil well.
So, what are some of the things that you should look at when buying OCTG tubing in China?
Tubing string
One of the things that you should check is the tubing strings. They must be of the correct size to facilitate a smooth flow of the fluids from the oil well to the surface. This helps to eliminate any leakages from the tubing.
The right stringing also helps to streamline the OCTG installation process. You will be able to attach the segments of the tubing to each other without any serious challenges.
An extremely large tubing string can result in the unstable flow of the fluid while a small tubing string can cause too much friction which will end up damaging the whole tubing segment.
OCTG tubing material
This is another key factor that you should consider when buying OCTG tubing for oil fields in China. The material will determine the strength hence the durability of your oilfield equipment.
When it comes to the choice of OCTG material, you should keep in mind the following factors which are likely to affect the physical state of the tubing:
-The environmental conditions of the oilfield
-Maximum and minimum pressure of the fluid
-Minimum and maximum temperature of the well
-The projected corrosivity of the oil well
-Safety of the equipment
Design of the OCTG tubing
The OCTG tubing must be designed to meet all the conditions of the oil well or wellbore. The design should enable it withstand the stress loads , tensional force, collapse and even burst.
The design should also minimize physical damage during the installation process and when it comes in contact with other equipment.
Although OCTG tubing manufacturers have stock designs of this tubing, you are free to request custom designs of this equipment.
