Hollow Sucker Rod

 

Hollow sucker rod is a new type of equipment for high pour point and viscous oil exploration, welded by seamless steel tube and hollow joint through the friction welding. In order to prevent leaking within and without and ensure the reliability of connection, the pushing and seal devices in the joint part of threads. It is used in the heat carrier petroleum engineering to meet the need of various petroleum engineering for a major application
