Stress chipping mainly due to the huge difference in thermal expansion coefficient ceramic layer and metal body caused. In most cases, the thermal expansion coefficient of the metal blank is greater than the thermal expansion coefficient of porcelain enamel reactor Zhengzhou manufacturer, which means that at room temperature the porcelain layer there is always a residual stress. Thermal expansion coefficient difference of residual stress, temperature, glaze layer thickness, substrate thickness and other factors. Glass-lined equipment thermal residual stress theoretical calculations. Compressive stress porcelain layer is sufficiently large, the porcelain layer will be peeled off. Open welded flange type reactor: a wider scope, generally low pressure (4.0Mpa below), the volume is generally less 3000L. This structure is based on the use of open flat at low pressure reactor lid relatively high price and design of one type. He has a convenient open repair disassembly advantages and disadvantages of longer duration.
