Dredging is one of the problems of industries and factories that sometimes scrimmage with it in different parts of their processes. Especially when the deposited material and wastes are at great depths, otherwise, the use of huge machines such as excavators, dredger pumps or even industrial vacuumloaders is not possible due to lack of space, and the issue will be much more complicated. The TDSL machine solves all these problems together. A machine that has a small volume and weight and can extract sedimented sludge, also  heavy materials such as pellets and pieces of iron and stone from the depths of wells, reservoirs and lakes.
This machine is one of the innovations of Nab Andish Sanat Asar Company, which is specially used in the steel industry and for dredging water and gas separation wells or seal leg.
Accumulation of heavy sludge of iron powder, pellets and other external wastes that enter the well during the operation of the plant, reduces the efficiency of the seal leg over time.  Extracting these materials with the help of existing methods and equipment such as dredger pumps, vacuum machines, water jets, etc., will not have the desired result.
Nowadays, the importance of clearing seal leg wells is so obvious that different factories, in each of their annual repairs, predict and perform this activity in the repair bar chart.
Nab Andish Sanat Asar Enterprise  Knowledge Company has successfully dredged more than 80  seal leg wells in various factories across the country, which shows the confidence of the steel industry to this company.
