It is widely used in high temperature boiler hot gas extraction, automobile exhaust emission, factory solder fume extraction, blast furnace exhaust and welding gas exhaust, etc. It is also used in exhaust equipment, engine structure, heating engine, dust removal and extraction workshop, heater exhaust, aircraft equipment and military conditioning bellows and compressors and other low pressure environments.

[0003] When a car exhaust is discharged, it contains a large amount of high-temperature, high-pressure and corrosive gases. The high-temperature exhaust pipe can effectively discharge these gases out of the car, while reducing noise and environmental pollution. The commonly used high-temperature exhaust pipe is made of stainless steel. It will be exposed to the air during use. If it is not isolated, it will cause burns to those who accidentally touch it due to its high temperature.
