According to natural laws, all metals are prone to corrosion. All metal structures gradually deteriorate due to different types of corrosion phenomena. Aging is inevitable and old structures need to be replaced with new ones - or would we have other options?
Bridges, wharfs, industrial structures, tanks, pipelines etc. are exposed to corrosion attacks in aggressive environment including salt from sea or de-icing on the roads as well as corrosive chemicals at industrial sites. Damage caused by corrosion or other reasons creates a safety risk or leads to the premature destruction of a structure.
Savcor saves resources, money and environment by extending the life of valuable assets. Savcor Online Structural Health Measurements help in managing and Savcor Electrochemical Protection Systems in extending the service life of metal and concrete structures, significantly.
EXTENDING LIFE OF PULP DIGESTERS, IMPREGNATION VESSELS, TANKS, PIPELINES
Savcor´s Anodic Protection stops corrosion cracking of the pulp digesters and the, impregnation vessels. A Savcor Anodic Protection (AP) polarizes the metal surface by rectifiers feeding direct current through the cathodes. Anodic current forms a strong passive oxide film on carbon steel and makes it corrosion resistant, even in the harshest environments. When installed in an old equipment, anodic protection prevents corrosion already in action.
ONLINE ALKALINE MEASUREMENT FOR OPTIMIZED PULP COOKING
Control of the make-up cooking liquor, as well as initial and resulting alkali concentration, affects the uniformity of pulp produced.
Savcor, together with Andritz, has utilized its long experience in electrochemical measurements inside the digesters and developed an accurate in-situ alkali measurement technology which enables more efficient methods to control the cooking process.
ANALYZING AIR CONTENT IN PAPER MACHINE STOCK WITH ULTRASOUND TECHNOLOGY
Sonica is an on-line air content analyzer designed to measure and monitor air in paper machine stock with ultrasound technology.
Sonica provides more accurate profile control and decreased consumption of defoamers with low operational costs.
SAVCOR CATHODIC PROTECTION STOPS DETERIORATION OF CONCRETE
A reinforced concrete bridge may suffer of heavy chloride induced corrosion on reinforcement steel in marine environment. Corrosion is a flow of electric current. Savcor Cathodic Protection (CP) system feeds opposite current to corroding steel and stops the damaging corrosion process. Savcor CP system extends the economic life of the bridge and cuts down the maintenance cost.

SAVCOR CATHODIC PROTECTION PROTECTS UNDER WATER STEEL STRUCTURES
Cathodic Protection can be applied to any metallic structure that is in contact with an electrolyte, such as wharfs, bridges and exterior of pipelines buried in soil or water.
In picture, corrosion of steel sheet piles buried in a corrosive soil or immersed in water was stopped by Savcor Cathodic Protection
(Sundsvall Bridge, Sweden, protected 2019).
SAVCOR ONLINE STRUCTURAL HEALTH MONITORING FOR CRITICAL CONSTRUCTIONS
Savcor Online Structural Health Monitoring System is essential in large valuable structures, often in critical positions, such as bridges, high-rise buildings and complex architectural showcase projects.
Online measurements detect design errors, potential damage or unexpected structural response of the structure. The slow structural fatigue caused by corrosion, often remains unnoticed, is clearly visible in the measurement results.
OBSERVING AND PROTECTING WIND MILL FOUNDATION
Savcor WiBE provides information of the bottom end of the wind mill. It measures the physical stresses and movement of the foundation regardless of the foundation type and location - onshore or offshore. The system delivers incident alerts and information of life expectancy calculations.
Used offshore or in demanding onshore soils, Savcor WiBE can be equipped with Savcor Impressed Current Cathodic Protection (ICCP) for external and internal immersed surfaces.
SAVCOR CATHODIC PROTECTION IS COST EFFECTIVE IN PROCESS EQUIPMENT MAINTENANCE
In the process industry, chemicals are stored in tanks and vessels made of metals, typically of steel or various stainless steels. When the process conditions change to more aggressive, the metal begins to corrode. Heat exchangers and piping are also typically prone for corrosion. Instead of replacing a corroding tank with a more noble and expensive material the most cost effective solution is to install a Savcor Cathodic System.
STRUCTURAL HEALTH MONITORING FOR COMPLEX DESIGNS
The modern design of buildings, like theatres or stadiums, have large open areas and due to a maximum visibility the number of support columns is minimized. The structure creates risks that can be detected already during the construction phase or during the use of building. In order to keep track on any movement, the whole structure is instrumented with Savcor Structural Health Monitoring System. The system consists of electrical and optical sensors detecting strain, displacement and inclination.
