A series of suction and blast hoses for use in high temperatures up to 1100°C and chemical applications is now available from flextraction Ltd, supplier and manufacturer of Local Exhaust Ventilation (LEV) products and authorised distributor of flexible extraction hoses in the UK and Ireland for NORRES Schlauchtechnik GmbH & Co. KG, the Gelsenkirchen, Germany based manufacturer of technical and industrial hoses.
These hoses depending on the type and size, vary in weight, flexibility and compressibility to meet their suitability for the application as well as the temperature ranging from -200°C up to +1100°C.
The hoses in the range made from Thermoplastic polymers are suitable for use in applications where the maximum temperature is 125°C. Hoses made of steel can be used up 400°C, whilst stainless steel hoses can be used up to 600°C. For better thermal insulation, multi-ply constructed hoses using alternating special high temperature webbing and special insulating materials are highly effective up to 1100°C over short periods.
One example of hose in this range is the VA 471 TEFLON ®, double layer, ultra lightweight, compressible hose which is designed for use in applications where operating temperatures can range from approximately -150°C to +250°C and over a short period of time in applications up to 270°C. Typical applications for these hoses include use with equipment associated involving aggressive solids such as dust particles, powder and fibres, also aggressive gaseous applications such as vapours, fumes and smoke, all applications found in the chemical industry, manufacturing de-dusting and suction plants as well as in bellows and compensators.
Another example is the NORRES CP HiTex 483 multi layer high temperature suction and blast hose designed for use in applications can reach up to 1100°C such as dust, powder and fibre solids, gas, vapour and flue gas extraction, blast furnace exhaust and welding fume extraction as well as exhaust extraction in engine construction, engine warming, aircraft and military equipment construction.
