The recirculation circuit is used in laboratories in order to create an analogue of the real working environment, for example, in power plants, pipelines, steam turbines, deep sea research, etc.

Outlines have the following benefits:

• the large volume of water passing through the circuit reduces the effects that corrosion products have on the chemical composition of the water.
• water is purified using ion exchangers, special filters and ultraviolet cells
• real-time monitoring of dissolved oxygen concentration, hydrogen, pH and medium conductivity
• creation of an environment with specified characteristics, which allows obtaining reproducible and high-precision measurement results

The contour allows you to simulate the conditions of the working environment at power plants, providing water of a certain chemical composition. Particular attention is paid to the monitoring of incoming and outgoing water flows, as well as the removal of water pollutants. An important part of the operation of the circuit is to control the concentration of dissolved oxygen and maintain a low electrical conductivity of water for experiments related to supercritical aqueous media.

Loops are used in the oil and gas industry to provide a larger volume of liquid through which ensures the stability of the chemical composition over a long test period. The circuit provides the high temperature and partial pressure of the H2S and CO2 gases, as these gases dissolve in the water tank at low temperatures. The circuits are designed to withstand the corrosive effects of H2S and CO2 gases. The structural material for the contour is quite often alloy C-276 (Hastelloy).

Cormet also manufactures high pressure and subatmospheric steam circuits that are used to simulate various kinds of steam turbine situations.
