NACE Corporate Member

18-02-2011

NACE International was originally known as "The National Association of Corrosion Engineers" when it was established in 1943 by eleven corrosion engineers in the pipeline industry. These founding members were involved in a regional cathodic protection group formed in the 1930s, when the study of cathodic protection was introduced. With more than 60 years of experience in developing corrosion prevention and control standards, with over 25,000 members in over 100 countries NACE International has become the largest organization in the world committed to the study of corrosion.

Silvion Ltd are pleased to announce that we are Nickle Corporate Members of this prestigious organization

Silvion approved by Corrosion Prevention Association

10-08-2010

The Corrosion Prevention Association represents consultants, contractors and manufacturers working in the field of corrosion prevention for concrete and masonry encased steel

The CPA acts as the leading authority and source of information on the subject of cathodic protection and other corrosion techniques and encourages research to ensure better understanding of the preservation of reinforced concrete structures and masonry clad steel framed buildings

Silvion Ltd are pleased to report that we have recently been audited by the CPA and been approved as a Corpoate Member.

Silvion Ltd look forward to being active members of the Association

SILVION Type WE300 Electrode tested by Imperial College London, Earth Science and Engineering Faculty

19-07-2010

Imperial College London (ICL), Earth Science and Engineering Faculty (ESEF) were looking for electrodes to be installed inside a well filled with 10E-4 formation water to measure streaming potentials (usually several mV) during waterflood. ICL identified Silvion Type WE300 silver/silver chloride electrode as suitable for their requirements but before proceeding with Silvion they needed to know what confining pressures could be held by the WE300 electrodes as the electrodes were to be submersed in water to a maximum depth of 100m (10 atm gauge pressure).

A sample WE300 electrode was tested in a ICL laboratory to determine if it could withstand pressures to 100m depth. ICL also carried out some comparison between voltages measured with the WE300 against their electrodes in the lab. ESEF measure voltages across sandstones saturated with low salinity NaCl brines (10E-2 M or less) using Ag/AgCl in-house custom made electrodes, stable to 10E-6 V.

Dr Jan Vingradov, ESEF said following the tests “I’ve just finished testing the Silvion sample WE300 electrode in the laboratory and it performs well. It is definitely capable of holding up to 10 bar of confining pressure and the voltages that were measured and recorded are consistent with our set of electrodes”.

Silvion are proud to report that we recently completed the supply of our Type WE300 and WE200 electrodes to ICL, ESEF for a field experiment they are conducting in an aquifer during August 2010.

SILVION Reference Electrodes chosen for Nakilat Ship Repair Yard, Qatar.

13-07-2010

Qatar Gas Transport Co QGTS.QA (Nakilat) awarded a $610.6 million contract to Daewoo Engineering & Construction Co to build a shipyard in Qatar. The Nakilat Ship Repair Yard is located in Ras Laffan Industrial Complex which is situated at the end of a 10km causeway and spread over 43 hectares, it contains an assortment of workshops and buildings as well as a total of approx 2km of quays and piers. The quays and piers are being constructed from 54 reinforced concrete caissons. The caissons are cellular in design with overall dimensions 36m x 16m x 11m and weigh around 4,000 tonnes each.

Due to the extreme environment in the Arabian Gulf the reinforcing steel within the caissons is protected from corrosion using cathodic protection. Sacrificial anodes provide temporary protection to submerged steel and impressed current systems are used to protect the structures for the next 50 years.

The Cathodic protection systems for these structures are designed and supplied by Corrosion Technology Services, CTS who have utilized the top names in component supply to meet the demanding specification for this prestigious project.

In order to determine the performance of the cathodic protection systems the steel reinforcement needs to be monitored effectively by the measurement of structure to electrolyte potentials. Embeddable reference electrodes are installed at representative locations over the entire structure to provide permanent monitoring facilities by burying the electrodes in the concrete so that they are very close to the actual reinforcement steel.

The nature of the project means that once embedded in the concrete the monitoring devices will be almost impossible to replace so selection was very important. CTS investigated the performance of different reference electrodes with some manufacturer’s electrodes giving a wide and variable potential range to a standard portable reference electrode.

Silvion WE100 Ag/AgCl reference electrodes were selected due to their accuracy, stability, superior performance and unmatched track record. These reference electrodes are installed as part of a cluster containing a reference electrode, a current pick up probe and an instrument negative connection. In all there will be almost 700 Ag/AgCl Silvion reference electrodes installed on the project.

Silvion are delighted that our reference electrodes have been chosen to monitor the performance of the above cathodic protection systems and we are very pleased to have been involved in such a prestigious project

SILVION 25 Years of Excellence

31-08-2009

SILVION - 1984 to 2009

25 years service to the Corrosion Prevention Industry

SILVION was established in April 1984 by Dr Pathmanaban, an Electrochemist with considerable experience in the use and manufacure of silver/silver chloride electrodes used in the Corrosion and Battery Industries.

SILVION, pioneer's of silver/silver chloride reference electrodes for concrete structures supplied our first electrodes for concrete application in 1985 giving us an unrivalled 24 year UK track record of providing permanently embedded electrodes for concrete cathodic protection systems.

Since those early years SILVION have supplied over 60,000 reference electrodes worldwide
