Coated oil drill pipe surface derusting device

technical field

The invention relates to a coated oil drilling rod surface derusting device.

Background technique

After use, the surface of the oil drill pipe will form a dirt layer and rust layer. During equipment maintenance, the oil drill pipe needs to remove the dirt layer and rust layer on the surface. The operation of the prior art is to use a manual hand-held grinder for grinding. To remove the dirt layer and rust layer, this method has the following disadvantages: the construction period is long, the construction personnel’s operation intensity is high, and the efficiency is extremely low. It takes at least 3 days to remove an oil drill pipe, and other auxiliary equipment is needed to help rotate it. The construction environment of oil drill pipe is harsh. Due to the existence of petroleum substances and rust substances on the surface of the used oil drill pipe, when grinding, the high temperature and high-speed rotation will lift the rust dust into the air, and the construction workers will inhale the pollutants. , which is extremely harmful to construction workers.
