Shell-and-tube heat exchangers, tube bundles to them and tube-in-tube heat exchangers of type TU

TU type shell-and-tube heat-exchange apparatuses (hereinafter referred to as apparatuses) are designed for heat exchange - heating, cooling, evaporation, condensation of liquid and gaseous media in technological processes of oil refining, petrochemical, chemical, oil, gas and other industries. The design of the apparatuses is technological, reliable during the service life specified in the technical documentation and ensures safe operation. The apparatuses are made of carbon, alloyed, stainless, heat-resistant or bimetallic steel. Heat exchanger tubes made of carbon, alloyed, stainless or heat-resistant steel and brass tubes are used. The apparatuses fully comply with technical requirements (GOST 31842), technical regulations of the Customs Union, industrial safety rules and technical conditions (GOST 34347 and TU 3612-100-00220302-2005).
