Qısa məlumat

The article contains review and analysis of sucker rod selection methods in terms of fatigue criteria as well as their association method. The selection methods are represented by the maximum allowable reduced stress by A.S. Virnovsky and the modified Goodman diagram. On the basis of described association the new calculation method of maximum allowable stress for pump rod, including rods of new constructions has been developed. Instead of long term field tests of a sucker rod pilot batch the method involves only ultimate stress as the rods materials characteristic.
