Use

Such a tube is used in the production of various mechanisms and parts, including pipeline systems, whose work is carried out under moderate tension. Pipe KHN70JU use in parts of the burner. It is used in the manufacture of covers electrical thermometers because it does not pollute the electrodes thermocouples and provides reliable protection of the thermocouple wire when working in hazardous conditions. KHN70JU pipe can withstand the temperature of 1250−1300°C for a long time under load. Therefore, it is used for parts of internal combustion engines, furnaces, steam and gas turbines, jet engines, etc.

Pipe KHN70JU also stable in air and gas environments to corrosion at high temperatures. Pipe, alloy of aluminum and silicon, capable of withstanding contact with the aggressive medium because in the process of heating these substances on the surface to form a protective film — oxides of aluminum, chromium, etc., This pipe is plastic enough that you can use it in the construction of chimneys and other pipe systems at any angle.
