General

This standard defines minimum physical quality and inspection requirements for bracelet galvanic anodes for offshore pipeline applications, including risers and J-tubes.

This standard is applicable to the majority of bracelettype anodes used on offshore pipelines, i.e., anodes of halfshell or segmented configurations. For other anode designs, such as semi-cylindrical segments with cast-in longitudinal notches, an experienced corrosion specialist should be responsible for defining the acceptance criteria.

This standard does not specify particular anode alloy compositions or define short- or long-term performance tests.

This standard does not specify particular anode or anode insert designs. An experienced corrosion specialist should be responsible for anode and anode insert design.

Although some aspects of this standard may be relevant to other types of galvanic anodes, it is not intended to apply to platform, hull, tank, or extruded-type anodes.

This standard does not address electrochemical or other anode performance test procedures. NACE Standard TM01901 gives a standardized short-term potential and capacity determination test procedure for quality control purposes in international laboratories.

The manufacturer is responsible for meeting the quality levels specified in this standard. The purchaser shall determine the extent of inspection to be conducted by the purchasing organization to prove compliance with the quality specified.
