1. Product Introduction: Our zinc strip sacrificial anodes (shortened to zinc strip) meet the ASTM-B418 (Type 1/Type 2) standard. They are primarily used for protecting pipelines inside casings, temporary cathodic protection of pipelines, protection of storage tanks and pipelines, and to prevent AC interference and lightning interference from high-voltage lines on buried pipelines. They require no external power source, feature a continuous conductive core, and have minimal electrical connections. They can serve as grounding electrodes, release AC and lightning, and protect equipment and personal safety. 2.
