If you want the flame retardant bellows to have good elastic properties, heat treatment is an indispensable process. Heat treatment of bellows can eliminate work hardening in the manufacturing process, restore the plasticity of flame retardant bellows, and strengthen the material to obtain elasticity. The heat treatment of bellows has its quality requirements both inside and outside. The internal requirement is to obtain certain microstructure, grain size and mechanical properties of the product after heat treatment; The external quality is mainly the surface oxidation degree after heat treatment.
Surface treatment of flame retardant Corrugated Tube
Process treatment mainly includes oil removal, loose moving oxide and pickling processes, so that the surface of the flame retardant bellows product is smooth.
Shaping technology of flame retardant Corrugated Pipe
After the bellows are formed, because of the elastic rebound, the wave distance and wave pattern of the bellows are different from the requirements of the suction meter, so it must be shaped. For the flame retardant Corrugated Tubes made of work hardening materials, generalists use manual and mechanical shaping methods. For the flame retardant bellows with diffusely-hardened materials as raw materials, the bellows are shaped by loading into the aging fixture, and the shaping effect is finally achieved.
