Mats Akoterm STI

AKOTERM STI is a ready-to-use product consisting of mineral wool strips glued to the coating material.

AKOTERM STI are intended for thermal insulation of pipelines and ducts of round, square, rectangular cross-section and apparatus at a temperature of insulated surfaces from -120 ° С to 500 ° С with a coating layer of fiberglass and from -120 ° С to 250 ° С with a fiberglass coating and aluminum foil.

STIs are available in diameters from Ø108 and above. By agreement with the consumer, the manufacture of products with a diameter / size of Ø57 is allowed.

The types of coating materials used are PCT (P) fiberglass, fiberglass (T), aluminum foil (A), as well as any other rolled material as agreed with the customer.

 

Legend example:

Prefabricated heat-insulating mineral wool vertically layered AKOTERM STI grade 75 coated with aluminum foil 3000 mm long, 1000 mm wide and 60 mm thick:

STI 75/А-3000.1000.60. TU BY 101474788.001 — 2011

 

STI mounting technology: the product is wrapped around an insulated surface and secured with a bandage.

The main features and advantages of AKOTERM STI:

  • the possibility of manufacturing both for a specific diameter of the pipeline, and of any length according to the customer's request;
  • STI design allows during installation to withstand guaranteed design thickness of the heat-insulating layer over the entire insulated surface;
  • installation of STI is carried out with minimal labor;
  • after installation STI retains its original thickness throughout the entire period of operation.

Recommendations for transportation, storage and installation

  • During storage and transportation it is necessary to protect products from moisture. Products rolled up in rolls must be stored and shipped in a vertical position to a height of not more than two meters.
  • At the construction site, the insulating product is wrapped around the pipeline and secured with galvanized metal wire bandages, steel or polypropylene tape in the amount of three bandages per mat.
  • When arranging the insulation of vertical pipelines, ducts, and containers, the thermally insulated product is rolled up to the scaffold, where it is unpacked and wrapped around an insulated surface.
