KLETTI can also play it cool

The pressure hoses from KLETTI form the basis of the heated hoses; in addition, they can be used in many other areas as cold hoses without heating and insulation. The hoses are resistant to chemicals such as acids and alkalis in any concentration. Exceptions to this are molten alkali metals and fluorine compounds.

The hose basically consists of an inner core made of PTFE, PA or stainless steel, the steel braid and fittings on both sides. The even wall thickness of the inner core has a significant influence on the lifespan of the pressure hose. Depending on the compressive stress, the core is wrapped with one or more layers of steel wire, wound or built up in combination. The fittings are positively pressed with the pressure hose so that the hose can withstand the desired compressive stresses.

Pressure hose types

The selection of pressure hose types is determined by the required operating pressure depending on the operating temperature.
