VPI’s sacrificial anodes for protection against corrosion
Abstract
The sacrificial anode is one of the most effective methods to protect against corrosion of metal in an electrolyte environment. Aluminium, zinc, and magnesium are the metals mostly employed for sacrificial anode cathodic protection of metals. Each sacrificial alloy anode with different closed-circuit potential and electrochemical capacity can be used in different conditions and environments. This paper presents the sacrificial anodes manufactured by the Vietnam Petroleum Institute (VPI) and their qualities. VPI’s sacrificial anode products have been certified by international accreditation organisation (DNV) to conform with DNV RP B401 standard, and the quality management system of VPI has been assessed and found to conform with the requirement of ISO 9001:2015 standard. VPI's products have been installed in petroleum structures and appreciated by customers.
