A Steel Alloy, its use, a procedure for obtaining a Pumping Rod composed of the Steel Alloy and a method for fabricardicha Pumping Rod

摘要

An Alloy Steel is described, which is based on a modified AISI 4142 whose chemical composition expressed in weight percent is as follows: c = 0.40 0.60 - 1.00 = 0.75, MN -, si = 1015 - 0.50, p.mu00e1x = 0.020, s.mu00e1x = 0.015, Cr = 0.8 - 1 = 0.15 - 0.25, MO, Cu = 0.12 - 0.25, sn.mu00e1x = = 0.003, 0.01 - 0.04, as.mu00e1x = 0.01, v.mu00e1x = 0.14, N.Max = 100 ppm, or maximum total = 35 ppm, the rest being Iron, Alloy comprising a microstructure which allows the Anchorage of pelu00edculasprotectoras carbonates ysulfuros,Roestructura MIC is the product of thermal treatment of standard, with Cooling rate controlled, and subsequent annealing of the modified Steel.It also describes a procedure to obtain Alloy, for subjecting an ac ero 4142 modificadocon AISI chemical composition indicated above.A Heat Treatment of Normalized with Cooling rate controlled,The use of laaleacion and subsequent annealing to make Rods of the bombeoresistentes corrosio n for Oil,Pumping Rods Made Of Steel Alloy and Process for producing sucker rods, which includes subjecting to a Heat Treatment StandardWith speed controlled deenfriamiento, and subsequent re came, a Pumping Rod with a modified composite Steel AISI 4142 which has the chemical composition given above.The Rods are debombeo individually in oil wells with otrapor through a coupling, forming the deno MINED string (Figure 1).In Figure 2 apreciael device that transmits the Downstroke and upstroke of the string, which in turn drives the pump located at the bottom of the well.The microestructuradelcuerpo Rod consists of Tempered bainite which gives the material The Resistance level required to service a Grade D (Figure 3).
