Mining and metallurgical industries
MINING AND METALLURGICAL INDUSTRIES
Mining and metallurgical industries constructions and equipments are exploited in the toughest environments for example:
- polluting gases (acid and others);
- high humidity, condensate;
- process liquids;
- dust;
- high temperature.
Severe service conditions of the metal construction and heightened requirement to their operating conditions determine necessarily to protect them from corrosion. VMP HOLDING has developed the coating systems to provide corrosion protection of the metal, concrete and ferroconcrete constructions and equipments of the ore-dressing plants, metallurgical works, and mining and smelting plants:
- supporting constructions, shops, overpasses;
- manufacturing equipments;
- energy sector constructions: transmission towers, constructions and equipments of substation;
- infrastructure constructions and equipments such as cranes, railings, water-cooling towers, pipings;
- concrete and ferroconcrete constructions.
VMP coating systems satisfy the requirements of ISO in corrosion protection and provide high performance protection of the constructions of mining and metallurgical industries.
VMP coating systems are included to GOST 9.401-91 "Unified system of corrosion and ageing protection. Paint coatings. General requirements and methods of accelerated tests on resistance to the action of climatic factors" and recommended by Gosstroy of Russia (SNIP 2.03.11-85, recommendation Р 1-2004).
VMP coatings successfully passed tests and have certificates and conclusions of NII LKP with ОМZ «Victoriya»; Central Scientific and Research Design Institute n.a. Melnikov, NIIZHB.
