HSCI anode

HSCI anode

  HSCI anodes have been used for many decades to protect buried and submerged structures from corrosion. This anodes can operate effectively in a variety of electrolytes, from soil and freshwater to brackish and salt water environments. Under normal conditions, a thin film of silicon dioxide will develop on its surface, this film protects the anodes from metal pitting and makes them ideally suited for deep groundbed application.

  Yuxi started to manufacturing HSCI anode since 2005, and in 2010 Yuxi had a joint venture business with former UK Silicon anode manufacturer Jennings foundry (former Durichlor 51 Anode supplier) to develop the casting technology together. Until today, Yuxi offers both stick and tubular anode for the industry with various available.

General Specification

Thanks for the progress of cast technology, tubular anode was invented after some years of stick anode. And now the tubular anode is very well recognized by CP designers and engineers and became the most popular for deep wells. The tubular anode has the following advantage against stick type.

l  Low resistance center connection is typically for tubular anode to compensate for end effect, because more current discharges from the anode end than the middle.

l  More economics because of higher utilization than traditional stick anode, tubular anode can use 85-90% of its mass weight while stick anode only 60-70%.

l  More surface area per kilogram which reduce the anode current denisty.

l  Tubular anode can be casted to 2134mm long while stick anode only limited to 1524mm, that brings the advantage of lower resistance than stick type.

l  Easy transportation and handling due to more surface area per unit weight, for a certain current requirement the weight of tubular anode is much smaller than stick anode.

Yuxi manufacture a full line of tubular anodes using improved centrifugal casting technique, this helps us to bring our anode quality to a new level compare to gravity casting.

l  More dense and homogenous structure

l  `Stipple effect increase surface area

l  Level 1 X-Ray detection AS per ASTM E186/E446

l  More impact resistance due to higher density

Canister HSCI Anode:

HSCI anode can be buried directly in the groundbed, and besides that canister type anode is produced to easy installation for a deep well.
