Oil is the most important energy in the world at present. It is widely used. Many equipments need oil to operate normally. For example, we often use cars, airplanes, generators and so on. Without oil, our life would be a very big change.


So now, oil drilling is going on uninterruptedly. Thick-walled seamless steel pipes with this material were widely used during oil drilling. Many people may be confused that the thick-walled seamless steel tube is hollow, and its strength is smaller, so it is better to use solid steel columns.
 
Indeed, the strength of solid steel columns is much higher than that of thick-walled seamless steel tubes. However, the strength of thick-walled seamless steel tube is still very strong, the most important thing is that it has a great advantage, that is, its vibration is very small. After all, the thick-walled seamless steel pipe is hollow. When drilling, it can transfer the impact force well, keep the bit stable, and drill in petroleum is the best choice.
