LEMAT TECHNOLOGIES IN FIGHTING THE CORROSION OF THE HYDRAULIC SYSTEMS

CORROSION IS DANGEROUS! It is the greatest threat for the hydraulic systems made of steel. It attacks quickly and ruthlessly, it digs into the material, narrows down the diameter of pipes and decreases the flow rate. This results in frequent and costly breakdowns of the installation. The final effect of its destructive actions is an inevitable and complete destruction of the system. However, we are neither helpless nor convicted for irreversible results of the corrosive processes.

THE CORROSION CAN AND SHOULD BE FOUGHT. There are different methods and ideas used in the fight against corrosion. They don't bring equal effects and some of them are good in theory or in the laboratory conditions, but not always as effective in practical use. When deciding to fight corrosion, one should take into consideration the methods and technologies that are effective, practical and have turned out to be useful under real exploitation conditions. The technologies offered by LEMAT - a firm specialized in fighting the corrosion of hydraulic systems - meet all of these requirements.

WHEN FIGHTING THE CORROSION, USE THE MOST POWERFUL WEAPON - THE TECHNOLOGIES OFFERED BY LEMAT. LEMAT has implemented, improved and created reliable, efficient and extremely effective technologies that help reducing to minimum the effects of corrosion and prolonging the efficiency and vitality of the hydraulic systems. For central heating systems LEMAT offers our own, original and patented technologies. They are so far the most modern and most powerful weapon against corrosion. Their basis is the known and highly valued method of electrochemical corrosion protection created by A. Guldager, developed and adopted by LEMAT. Their efficiency and effectiveness exceed any other known method of reducing corrosion.

PROTECTING NEW INSTALLATIONS brings definitely the best results. It allows securing the installations before the corrosive processes begin their destructive actions. Therefore it is a rational and responsible way of managing these resources. Until now, the systems of electrochemical corrosion protection were only used to protect brand new or barely used water installations. Now, after many years of experience, LEMAT has made another breakthrough, making it possible to protect even older installations that had already been exposed to corrosion.

PROTECTING THE INSTALLATIONS IN AN ADVANCED STAGE OF EXPLOITATION is as far the greatest technological success of LEMAT. We are able to clear these installations of corrosive sediments and afterwards secure them from the disastrous effects of corrosion. This way we prolong their vitality and put away the moment when expensive replacement of the installation is required.

The efficiency of the LEMAT systems of protection is not only confirmed by theoretic calculations and laboratory tests, but also the effects we have achieved in practice. The pictures presented below are a proof of perfect condition of the installations protected from extremely corrosion-inducing water in Warsaw.

Section of a central heating pipe protected with LEMAT systems from the beginning throughout 11 years of exploitation (3A Okaryny Street)		Section of a central heating pipe after 26 years of exploitation protected by the LEMAT systems after 15 years of an unprotected exploitation (12 Puszczyka Street)

The following scheme displays the possible ways of managing the central heating installations. Next to a passive approach, which leaves them to quick and disastrous action of corrosive processes, we present the effects achieved by applying LEMAT systems of corrosion protection in different phases of exploitation. The choice is easy and obvious.

LEMAT TECHNOLOGIES GUARANTEE SUCCESS

These schematic examples are a documentation of the effects achieved thanks to active, responsible way of managing the central heating installation under Polish conditions. Thanks to the LEMAT protective systems even the installations in an advanced stage of exploitation are highly efficient and effective. The sections of the pipes are characterized by

FULL FLOW PERMEABILITY, LACK OF SEDIMENTS AND INHIBITION OF CORROSION

However, rational management of the central heating installations requires making quick decisions about their protection. The sooner such decisions are taken, the better the results can be achieved. At some critical point the condition of the installation is so bad, that no positive effect can be achiever, regardless to the applied method. LEMAT creates evaluations which allow predicting the chances of successive protection of the installation and apply the best protective methods. The procedures for the installations in I and II phase of exploitation consist of two basic technological stages:

Stage I CHEMICAL CLEANING OF THE INSTALLATION consisting in dissolving and removing the sediments and corrosive deposits as well as preparing the internal surface of the pipes for the second stage.

Stage II PROTECTION FROM CORROSION by installing the LEMAT electrochemical system.

The description, characteristics and other data describing the LEMAT protective technologies are detailed in the information leaflets. They are also available on our website other pages.

The Enterprise of Corrosion Protection LEMAT is the only one in Poland offering the technologies described above supported by thorough approach towards fighting corrosion. LEMAT technologies, apart from being extremely efficient, are also highly effective and bring great savings.

EFFECTIVENESS - measured only as a result of saving the costs of a single replacement of the installation - places the LEMAT technologies in the group of the most profitable and attractive investments in the building industry. The synthetic data compiled for one of the housing associations in Warsaw confirm this thesis.

SAVINGS achieved by applying the LEMAT technologies are not only the result of avoiding the replacement of the installation. They are also a result of limiting the costs of the installation breakdowns.

The chart shows the reduction in the number of breakdowns after applying the LEMAT protective technologies and replacing the thermoregulation valves in 22 buildings in Ostrobramska Estate in Warsaw. These buildings were in 1999 the subject of a two-stage rescue operation created by LEMAT. The installations were chemically cleaned and afterwards the systems of electrochemical corrosion protection were installed.

LEMAT PROTECTIVE TECHNOLOGIES became in Poland an extremely useful, effective and efficient weapon against the corrosion of the water installations. They also ought to become a commonly used, essential stage of every rational program of thermo renovation in Polish building industry.
