Water tanks

VMP HOLDING has developed the coating systems based on zinc-rich primers for corrosion protection of tanks and equipments for potable water supply, hot and cold water systems:

- tanks for potable water;

- water tanks;

- decarbonising tanks;

- deairing columns.

VMP coating systems passed the total industrial certification and are included to the normative documents:

- Practical recommendations for water tank corrosion protection and water protection from airing RD 153-34.1-40.504-00;

- Manual for choice and application of coatings for marine tanks of potable and bath water YAKUT 25-055-2000 (CNIIMF);

- Manual for corrosion protection of internal surface of ballast water system and tanks YAKUT 25-069-2001 (CNIIMF);

- Recommendations of Gosstroy of Russia (SNIP 2.03.11-85).

ZFES coating has the State Registration Certificates for application in the hot water supplying systems for internal surface of tanks, piping and other equipments contacted with hot water (№№ 66.01.31.001.P.002576.08.07, 66.01.04.000.Т.000130.06.05).

		ZFES, 4 coats (160-180 microns)	6-8
	high	ZFES, 4 coats (160-180 microns)	4-6
		ZFES, 5 coats (180-200 microns)	6-8
Repaired tanks	low	ZFES, 4 coats (160-180 microns)	4-6
		ZFES, 5 coats (180-200 microns)	6-8

* water is supposed high corrosive if oxygen concentration is more than 50 μg/l, carbon dioxide concentration is more than 10 μg/l, Langelier's Index is negative, рН is not more than ZFES coating limits..

** surface preparation is 2 degree by GOST 9.402-2004 (Sa 2½, ISO 8501-1:2007).
