Rubber industry thermal oil furnace price 2-ton gas thermal oil boiler manufacturer

Description :

industrial boiler When using pipes for hot bending processing, different processing techniques should be selected according to different heating methods.

　　The heating methods for bending pipes used in industrial boilers include:

　　1. When using an intermediate frequency converter, the intermediate frequency induction heating coil is used for heating.

　　2. When manually bending pipes, small-diameter pipes are heated using an oxygen propane heating coil.

　　3. When manually bending pipes, large-diameter pipes are generally heated using a heating furnace.

　　When heating, the entire curved part of the pipe should be heat permeable and uniform, and carburizing should be avoided when heating stainless steel pipes. The temperature range for heating various carbon steel materials is between 800-950 ℃, and the heating temperature for alloy steel should be adjusted according to the material.

　　Small diameter or relatively thin wall pipes used in industrial boilers are generally manually bent using sand filling, and the sand can be river sand or quartz sand. After bending the pipe, the heating part should be cooled. For alloy steel pipes with a high tendency to harden, water should not be poured for cooling after bending.

　　When there is a limit to the thinning amount of the bent pipe, a push bending pipe bending machine should be used for bending.

　　After the hot bending of pipes for industrial boilers, they should be inspected on the layout platform and stored for later use after passing the inspection.
