class T sucker rod coupling

详情

Its wear-resisting performance is larger than normal joint; it is obvious especially under the bad condition, and the service life lasts *0 times than before. The abrasion to the rod is reduced by 3 times after you using this joint. Also, the friction resistance is reduced by ****5%, saving land electricity waste, increasing the operating safety, decreasing the accident rate. The size of the joint is not changed too much; there is also no additional requirement for the operation under the well. The connection of rod is simple and the technology management is convenient. The operation of it is according to the normal way. Prolonging the period of repairing well(maintaining pipe), reducing the cost of well repair, increasing the productivity and using rate of the oil well.
