Merits
- Completely removes scales in tube inside and around fitting parts.
Thus our cleaning system allows cleaning interval much longer than
that of existing systems of other companies.
- Reduces the cleaning time.
- Is available for the tube inside of any kind of heat exchanger.
-> COPPER
-> CUPRO NICKEL
-> STEEL & CARBON STEEL
-> ALUMINIUM BRASS
-> TITANIUM
-> STAINLESS STEEL
- Is available for every tube wall thickness from 5/8" to 1 1/4" size.

Various Kinds of Tube Cleaner
An exact cleaner size in accordance with the inside diameter of tube is required because of tightness between tube wall of tube inside and metal cleaner vane. Wrong-sized cleaners greatly reduce cleaning efficiency. Metal cleaners from 5/8" to 1 1/4"(Tube O.D.)can clean tube inside of any size. Tube I. D. is different according to tube wall thickness. Sizes of metal cleaners are on the next page.
Structural Features
- FLEXPIG tube cleaner is designed to form vacuum area by acceleration of SSR 3 stage vane.
Which assures satisfactory cleaning of even tiny scales around
the pitted unit.
- Various sizes of 4 stage twist steel vanes, which are designed to
fit tightly in accordance with any size of tube inside,
perform perfect cleaning by scraping hard scales.
- SSR flexible core allows more effective removal of scales..
Ideal Cleaning of Tube Inside
Dust, coke, hard scale and other deposits in condenser tubes of power plants not only reduce heat efficiency but also cause tube corrosion and leakage. Thus scales should be removed periodically for high efficiency of condenser and long usage of tube. Kukil's long experience and the latest techonlogy developed the most ideal tube scraper for cleaning condenser tubes of power plants and Kukil's tube scraper is available for every tube thickness from 5/8" to 1 1/4".

Special Features
A shot of high pressure water jet cleaning can
- Remove deposits, pit peaks, hard scales and fouling simultaneously.
- Avoid possible damage of tube inside with cleaner's vane scraping
in water flow.
- Preserve adequate water flow because FINPIG cleaning can remove
unevenness of tube inside.
