I guess there are many people  will be puzzled, thick-walled seamless steel pipe is hollow, its strength should be small, why do not use of solid steel column? Indeed, the solid steel column compared to thick-walled seamless steel pipe, its strength is much higher. However, the strength of thick-walled seamless steel tubes is also very strong, and the weight is lighter than the solid steel column. The most advantage of it is that the vibration is very small. After all, thick-walled seamless steel pipe is hollow, in the drilling time, it can be a good transfer impact force, so that the drill to maintain a smooth, for oil drilling, is the best choice.
