scope:

This standard specifies metallic material requirements for the construction of sucker-rod pumps for service in corrosive oilfield environments. API(footnote 1) Spec 11AX provides dimension requirements that ensure the interchangeability of component parts. However, that document does not provide material specifications or guidelines for the proper application of various API pumps. API RP 11AR does list the general advantages and disadvantages of the various pump types and lists the acceptable materials for barrels and plungers; and API RP 11BR supplements API Spec 11AX by providing corrosion control methods using chemical treatment. This NACE standard should supplement the use of the aforementioned API publications.

This standard was originally published in 1976 and was revised in 1994 by NACE Task Group T-1F-15 on Sucker-Rod Pumps for Corrosive Environments, a component of Unit Committee T-1F on Metallurgy of Oilfield Equipment. It was reviewed by Task Group T-1F-28 and reaffirmed by T-1F in 2000. This standard is issued by NACE International under the auspices of Group Committee T-1 on Corrosion Control in Petroleum Production.
