The importance of heat treatment in pipeline heating is obvious to all, but often in practical applications, we will find that the diameter and wall thickness of some pipelines are very large, and the ceramic heating sheet cannot be completed, so POLARIS-ETeK The developed intermediate frequency heat treatment equipment perfectly solves the process that cannot be completed by the ceramic heating sheet through its own advantages of high power density, and has also become the first choice for heat treatment of large-diameter pipes.
And according to the survey of power plant pipeline construction data, 30%-40% of the working conditions can only be completed by intermediate frequency heat treatment equipment and cannot be completed by ceramic heating sheets.
In particular, the intermediate frequency heat treatment equipment developed by our company has the most obvious advantages in the heat treatment of P91/92 pipes, and our company's equipment has been used in many power plants, with a success rate of 100%, such as Pingliang Power Plant, Yimin Power Plant, etc;
The picture above shows that the flexible cable is evenly wound around the pipe to heat it.
The above picture is the site map of the medium frequency heat treatment equipment heating the container (especially the container installation space is limited, Medium Frequency Heat Treatment Equipment can provide high-density power in the limited space, and these are the advantages that the ceramic sheet heating does not have)
Advantages of PWHT Machine:
1. Induction heating is to make the metal self-heat, relative to the resistance heating, and the heating efficiency is as high as 30% or more;
2. The penetration ability of the medium frequency electromagnetic wave can achieve the effect of uniform heating;
3. The equipment has high power density and fast heating speed, which can significantly improve work efficiency;
In addition, Intermediate Frequency Heat Treatment Machine is also widely used in chemical industry, shipbuilding, pre-weld preheating and post-weld heat treatment of steel structures;
