Abstract
The invention relates to a production method and a remanufacturing method for hollow sucker rods. The biggest characteristic of the production method for the hollow sucker rods lies in that to the head of each hollow sucker rod is upset, and the quench and temper treatment are conducted on the whole hollow sucker rod, so that the strength uniformity of the whole hollow sucker rod is ensured and prevent the possibility that the problems of the welding parts of the body and the head of the traditional hollow sucker rod are easy to occur can be eliminated completely. The effects of recycling the resources, saving the energy and reducing the cost can be realized through recycling the waste hollow sucker rods, and the cyclic utilization problem of the waste hollow sucker rods can be effectively solved by processing.
