Chemistry & Petrochemistry

In a broader sense, the chemical industry includes those industries that deal exclusively or primarily with the conversion of natural raw materials and with the production of synthetic raw materials. For example, TDI is the basic product for the specialty plastic polyurethane. This is used for the most part in the automotive and furniture industries, for example in seat upholstery or interior trim. The chemical products produced include plastics, foams, adhesives, rubber, wax, cleaning agents, paints, fertilizers, etc. In the course of processing, gaseous, liquid and viscous substances, as well as pasty media, must be maintained in a liquid state or kept at a specified temperature for transport or further processing. In the chemical industry in particular, a high degree of safety is also required. 

Temperature maintenance is therefore often indispensable, but it is not only products or precursors that require appropriate temperature control: many pipelines in which service water is transported, for example, are located outdoors in plants or chemical parks. These must be protected against frost to prevent the pipes from freezing.
