43、ncluding guidelines on selection, allowable stress, proper joint makeup, corrosion control and used rod inspection.2 ReferencesThis specification includes by reference, either in total or in part, the most recent editions of the following API, industry, and government standards, unless a specific ed
44、ition is listed:API Specification 11B, Specification for Sucker RodsAPI Technical Report 11L, Design Calculations for Sucker Rod Pumping Systems (Conventional Units)ASNT SNT-TC-1A 1, Recommended Practice, Personnel Qualification and Certification in Nondestructive Testing NACE MR0174 2, Selecting In
45、hibitors for Use as Sucker-Rod Thread LubricantsNACE SP0195, Corrosion Control of Sucker Rods by Chemical Treatment3 Selection of API Steel Sucker Rods3.1 GeneralThe selection of API grade sucker rods for a beam pump installation depends on a variety of factors, including stress effects, environment
46、al effects and rod grade. 3.2 Stress EffectsSucker rods need to be selected based on applied stresses. API 11L, Design Calculations for Sucker Rod Pumping Systems provides a procedure for calculating the applied loads or stress on a sucker rod string design.Sucker rod strength is limited by the fati
47、gue performance of the rods metal. This useful strength is dependent on the metals tensile strength as shown by Goodman (Goodman, “Mechanics Applied to Engineering” and Kommers, “Effect of Range of Stress and Kind of Stress on Fatigue Life”). This relationship is the basis for Section 4 of this docu
48、ment. According to the Goodman diagram shown in Figure 1, sucker rods operating in a non-corrosive environment and in the proper stress range will theoretically exceed 10 million load reversals. However, the fatigue life can be dramatically decreased by improper installation, design, handling or ope
49、ration even without corrosion. 3.3 Environmental EffectsSucker rods will eventually fail, even if not stressed, when placed in a corrosive environment. There is a reduction in sucker rod and coupling life if placed in a corrosive environment. However, the life of the sucker rod can be extended by the use of an effective corrosion inhibition program. In that case the expected life of a sucker rod can potentially be the same as a rod in a non-corrosive environment. 1American National Standards Institute, 25 West 43rdStreet, 4thfloor, New York, New York 10036, www.ansi.org.2NACE Internatio
