Device name：Oil pipeline
Oil and gas pipelines need to be cleaned and coated to prevent corrosion, and then steel pipe shot blasting machine is used to prepare for the final coating. The cleaning speed is fast, the efficiency is high, and the cost is low. The rod is the most critical component of the operating well and connects the pump driver on the drilling surface to the downhole pump. The steel rod is joined by a screw, and the maximum length is about 127 m. Enhanced treatment can reduce the residual stress accumulated in the inner lower hole of the sucker rod. The enhanced treatment also helps prevent rod corrosion by compressing the outer layer of the rod in the well.
