CathFlow® for storage tanks
The CathFlow® ICCP system is designed to cathodically protect underground storage tanks, regardless of size, electrolyte and coating conditions.
CathFlow® ICCP material package
CathFlow® ICCP system has the ability to cathodically protect any underground steel pipelines. regardless of size and coating condition.
The CathFlow® ICCP control panel can be connected to any kind of ICCP anodes and reference cells, and includes the following features:
- Accurate and smooth DC output current
- Flexible system with expandable output effect
- User-friendly operation
- Automatic logging
- Prepared for remote monitoring
Different ICCP anodes may be used for underground storage tank protection. Most common are cable-like polymer anodes and high silicon iron anodes. See the full range of ICCP products.
CathFlow® – designed to fit future demands for underground storage tank systems
MasterCath® – remote access software
MasterCath® works by pairing a remote computer with CathFlow® ICCP control panels installed for the pipeline.
The software provides an intuitive dashboard with realtime operational values, alarm detection and several other useful features.

Impressed current cathodic protection (ICCP) systems have the benefit of an external power source to impose protective current. This makes it possible to protect any buried structure, regardless of size and current requirement, by using long life anodes and appropriately sized power supplies. You may also want to read about design of corrosion protection for underground storage tanks.
The most important feature of an ICCP system is the ability to continuously monitor the level of protection and adapt to the current required to stop corrosion. Learn more about the principles of cathodic protection.
The CatFlow® ICCP system for buried storage tanks can be arranged either with cable like polymer anodes or pre-packaged FeSi anodes. Both anode types are energised by a controllable DC power supply. For both systems, it is recommended that measurement equipment, such as reference electrode and steel monitoring coupons are installed for control of the cathodic protection level.
The cable-like polymer anode can be installed as a loop around the entire tank, or as two separate cables at each side of the tank. The polymer anodes can be used for all types surrounding masses, but is particularly well suited for high resistivity. Simple installation, even current distribution and long lifetime are other benefits of the polymer anode.
Prepackaged FeSi anodes
Pre-packaged FeSi anodes are normally buried a couple of meters from the tank. The number of anodes depends on the size of the tank to be protected. The anodes can be used for most types of surrounding masses, are simple to install and have long lifetime.
In order to control the cathodic protection level, measurement equipment should be installed aside the tank. Due to very dense coating systems used, the measurement equipment should include both a suitable reference cell and a steel monitoring coupon for accurate cathodic protection potential measurements.
