Abstract
The utility model relates to a hot rolled round bar with key for fabricating the sucker rod used in the pumping unit of petroleum industry. The utility model comprises a round bar (1), two opposite lateral surfaces on the round bar (1) are equipped with keys (2), and the keys (2) on the different side are not aligned. The distance A between the keys at the same side is between 750 and 1160 millimeter, the axial distance a between two neighboring keys at the different side is more than and equal to 180 millimeter. The sucker rod with key fabricated by using the utility model can effectively prevent from the movement of the centralizer, thereby assuring no eccentric wear on the oil pipe from the sucker rod, assuring the normal operation of the pumping unit, and prompting the petroleum extraction efficiency.
Description
One, technical field
The utility model relates to a kind of hot rolled circular steel with steady nail, is applicable to a kind of sucker rod of making the oil equipment field.
Two, background technology
Sucker rod is the transmission device that petroleum industry connects oil pumper and oil well pump, oil development is to the middle and later periods, and bar pump oil pumping system working environment goes from bad to worse, the serious eccentrically worn tubing of sucker rod, cause pipe to break, manage the leakage accident, influenced the oil field to a great extent and normally developed.Use the anti-eccentric wear of centralizer in the rod string eccentric wear-proof process, to occupy an leading position, the user who wherein uses the plug-in type centralizer does not have to twine nylon on the steady sucker rod of following closely in existing smooth surface to fix centralizer, centralizer is displacement very easily, in addition under slide to box cupling, and lose centralizing function.
Three, summary of the invention
The purpose of this utility model provides a kind of hot rolled circular steel with steady nail, and the steady sucker rod of following closely of band with the utility model is produced can prevent the centralizer displacement effectively, thereby guarantees the operate as normal in oil field.
For achieving the above object, the technical scheme that the utility model is taked is: two sides that round steel is relative are provided with steady nail, the steady nail mutual dislocation of heteropleural.The spacing of the steady nail of homonymy is 750～1160mm, and two steady nail axial spacings that heteropleural is adjacent are 〉=180mm.
The axial cross section of steady nail is trapezoidal, and the height of steady nail is 1.4～2.3mm.
Because the utility model is provided with steady nail at sucker rod on the hot rolled circular steel surface, produce the sucker rod of the steady nail of band with the utility model, can prevent the centralizer displacement effectively, thereby guaranteed that sucker rod can eccentrically worn tubing, guarantee the operate as normal of oil pumper, improved oil exploitation efficient.
