Protection of steel underground tanks and reservoirs

Technology of anticorrosive protection of steel underground tanks using materials ABRIS

Protection of steel underground tanks and reservoirs

Scope of application:

  • Underground steel tanks and structures for various purposes with operating temperatures from –60 °C to +80 ° C;
  • The object of application can be underground drainage steel tanks, underground storage of LPG and petroleum products, heat exchangers, settling tanks and other technological equipment.

The design of the protective coating meets the requirements:

  • GOST 9.602-2016 "Unified system of protection against corrosion and aging. Underground structures. General requirements for corrosion protection";
  • GOST R 51164-98 "Steel trunk pipelines. General requirements for corrosion protection".

The main operations of the technological process of applying an anticorrosive protective coating based on the mastic polymer tape Abris  S-T to the tanks are:

  • Preparation of the tank surface for applying a protective coating;
  • applying the primer to the surface of the tank;
  • cutting strips of the Abris S-T tape in accordance with the required dimensions;
  • formation of the coating by gluing an insulating mastic-polymer tape with cold application of Abris S-T.

Advantages of the technology:

  • operating temperature from -60 °C to +140 °C;
  • resistance to aggressive environments, to seawater, to vibration loads, to hydrostatic pressure;
  • high resistance to cathodic polarization;
  • the possibility of applying in a "cold" way, i.e. without preheating the material or the surface of the structure;
  • the possibility of application in the highway and in the basic conditions;
  • the ability to perform work in conditions of negative temperatures;
  • manufacturability of protection of complex surfaces;
  • the absence of a technological operation for applying a protective wrapper;
  • possibility of manual and machine application;
  • possibility of production of protection of complex shaped elements;
  • compatibility with other insulation materials (serviceability).
