High temperature resistant air duct is widely used, how to distinguish high quality high temperature air duct
High temperature resistant air duct is especially suitable for hoses that require flame retardancy, solids such as dust and fibers, gaseous media such as steam and smoke; used for factory suction and dust removal, exhaust gas discharge, blower exhaust gas discharge and welding gas discharge.
High temperature resistant telescopic duct, high temperature ventilation duct, telescopic duct Properties: double layer, good heat resistance, stretchable; the outside is protected from wear by the spiral wire, and the external steel wire is tightly clamped on the pipe wall. Not easy to kink, strong toughness. Patented CP structure, external spiral metal wire support (metal sheet + wire), double tube wall.
Material: Tube wall material: internal and external stainless steel wire reinforcement and special glass fiber coating, spiral wire: stainless steel (VA);
Temperature range: about -60 °C to +900 °C, up to +1100 °C in a short time.
How to distinguish high-quality high-temperature air ducts?
Surface: Check the external and internal surfaces. The surface of a high-quality high-temperature air duct should be very smooth, free of stains, wrinkles, roughness and uneven spots.
Pitch: The pitch of the elastic steel wire and the glass fiber thread are the same, and the winding is even. The product bends freely and elastic
Material: A good high-temperature air duct is made of high-quality silicone rubber, which has stronger temperature and corrosion resistance. The glass fiber thread wound on both sides of the elastic steel wire is made of the same material as the base cloth, which also has the effect of temperature resistance and flame retardancy. Inferior high temperature air ducts are usually ordinary nylon threads used to save costs. They are not temperature resistant or flame retardant. .
