high efficient reagent-free technology of service of liquid media in pipelines and apparatus, providing two important improvements:

  • removal of all kinds of deposits

  • increase of pumping-over velocity of media


FLUID-LINER® technology has been developed in Germany and providing by group of companies SUTRA-IFT since 2001.


The set of equipment typically consists of two parts:


Electrical ecable,
wound on a part of pipeline

Electric cabinet


Equipment generates alternate electromagnetic field modulated with a special algorithm.


This field, penetrated into media through the pipeline wall, establish two physical effects:


1) Demolition of crystallization clusters,
return of impurities (salts and organic substances)
back into dissolved condition


2) Homogenization of suspended solids
(sand, suspensions) in the volume of pipeline

FLUID-LINER® technology is applied in different industrial areas



Depositing of salts and organic substances is well-known and important problem in the course of operation of liquid media pipelines, heat exchangers and other apparatus. It causes:

  • narrowing of pipeline section, down to complete blockage

  • reducing of exchangers efficiency

  • excessive load to pumping equipment

  • corrosion of pipes and apparatus


examples of blockage



Depositing causes forced wear of equipment, provokes often breakpoints for cleaning and repair of pipelines, increases consumption of expensive chemical reagents.


As a result, profitability and output of products are decreased.


FLUID-LINER® allows to remove or significant reduce problems related to deposits in pipelines, as well as to reach substantial economic benefit due to the dramatic reduction of losses and expanses

  • avoiding of overconsumption of heat energy (at heat exchangers)

  • keeping of production capacity of a shop (division), or increase of output

  • extension of lifetime and overhauls period of pumps, exchangers and valves

  • reduction of expenses for repair and recovery works

FLUID-LINER® provides increase of velocity of flowing of heterogenic operation media (pulp, suspension, sand-water mix) in pipeline, in average at ~10%.

This effect is certified with different media in pilot and industrial operational cases:





Pilot test: pumping-over of liquid concrete
at 1 km distance. Mokpo, S. Korea, 2014


Dredging with supply of sand-water mix at 12 km distance.
port of Gunsan, S. Korea, 2016-2018


FLUID-LINER® allows to reach substantial economic benefit with transportation of heterogenic media

  • increase of velocity of operational media, or

  • reduction of load and energy consumption of pumping equipment
