From the performance of galvanized pipe, galvanized pipe is internationalized, many galvanized pipe manufacturers in order to improve the corrosion resistance of galvanized pipe, galvanized steel was carried out in general, so producing galvanized pipe, galvanized into galvanized and galvanized, galvanized layer thickness of hot galvanized, electro galvanized low cost the surface is not very smooth.
The Ji'nan galvanized pipe includes the oil drilling pipe, the precision steel pipe and the oil pipe. Oil drilling pipe is mainly used to connect drill collar and bit and transfer drilling power. The precision steel pipe is mainly used in the drilling process and after completion of the well wall support, so as to ensure the progress of the drilling process and the normal work of all the wells after completion.
In the corrosive environment, the galvanized pipe in Ji'nan needs the corrosion resistance of the casing itself. In the case of disorderly geological conditions, there is also a need for anti collapse function of the casing. The precision steel pipe is the lifeline of the oil well work. Because the geological conditions are different, the downhole stress is in a mess, and the pulling, pressing, bending and twisting stresses play a general role in the pipe body, which requires higher quality of the casing itself.
This article is from Ji'nan galvanized pipe, friendship and dedication, and more related knowledge, please click: , we will use the most advanced technology and the most sincere attitude to provide you with the most comprehensive service. We will continue to contribute to you and look forward to it.
