GB/T 17731-2015 Magnesium Sacrificial Anode Cathodic Protection System
GB/T 17731-2015 Magnesium Sacrificial Anode Cathodic Protection System
Introduction:
The magnesium anode we provide has a negative potential and a large amount of electricity per unit mass, which is an ideal sacrificial anode material. It is suitable for cathodic protection of metal structures in media such as soil, fresh water and sea water. The magnesium alloy sacrificial anode is produced according to the national standard GB/T17731-2004 "Magnesium Alloy Sacrificial Anode", which is used for the anode of the pipeline, and also conforms to SY/T0019-97 "Design Specification for Cathodic Protection of Buried Steel Pipeline Sacrificial Anode"
Parameters:
Our products have the following specifications:
- " D " anode
- " R " Cylindrical anode
- " S " anode
