Model: BTDO -- I type

Product Introduction:
In recent years, thermal power generation units have been developing towards high efficiency and energy conservation. Therefore, stainless steel with better high temperature resistance and corrosion resistance is commonly used in large thermal power generation unit boilers to manufacture superheater pipes. However, after a long period of operation or a short period of over temperature operation, oxide scale is inevitably generated inside the pipeline. During temperature fluctuations, especially during shutdown and start-up, it is easy to accumulate at the pipe bend due to thermal stress peeling, and in severe cases, it can directly cause the pipeline to burst during operation.
The BTDO-I type non-destructive testing instrument for oxide scale inside boiler tubes adopts advanced electronic technology and electromagnetic detection technology. This instrument can quickly and effectively quantitatively detect the peeling and accumulation of oxide scale inside stainless steel tubes of power plant boilers, and eliminate the possibility of excessive oxide scale on stainless steel tubes causing tube bursting; At the same time, this instrument can also detect ferromagnetic foreign objects inside stainless steel pipes, such as iron filings, metal welding wires, etc.
Functional features:
● Lightweight hands, simple structure, easy to operate, no need for training;
Fast detection speed, quantified detection data, real-time display, no need for surface treatment of the tested object;
High sensitivity, able to accurately reflect small changes in the amount of oxide scale inside the pipeline;
Not only can it detect oxide scales, but it can also detect ferromagnetic foreign objects from other sources.
