Specifies metallic material requirements for the construction of sucker-rod pumps for service in corrosive oilfield environments. Gives tables of recommended materials for mild, moderate, and severe metal-loss corrosion environments, as well as tables of typical mechanical properties of pump barrel materials and plunger materials. Includes appendices on case hardening processes for steel pump barrels for an H2S environment and selection of optimum type of pump.
