Frame treatment of plate heat exchanger
Frame processing is part of the VGH Total Heat Exchanger Service Package. Our trained professionals will retrieve the equipment from your facility or ship it directly to one of our 7 service locations throughout China. Inspect the tie bar for any damage before loosening the bolts. Inspect the follower or gasket for cracks and deformation, as decompression can be dangerous if the unit is unstable. After the initial inspection, remove the frame and remove the board from the device. The lack of routine maintenance may require readjustment of the frame, as determined by the on-site VGH technician. Before any work is completed, VGH will send the customer a report of the disposition of the failed frame component or plate, taking into account transparency throughout the process.
Frame repair started by sandblasting old paint from the shell, exposing the core metal surface. VGH repairs any external defects and then applies a new coat of VGH blue paint (or color choice). The zinc protective coating is suitable for all tie rods and should only be replaced if necessary. The lining will also be replaced as needed. Sanitary (solid stainless steel) frames rarely need to be refurbished, but sanitary frames may need to be rebuilt and we can adapt during frame processing. 清洁 和 染色测试 过程后，它们就可以重新安装了。 After the plates have gone through our cleaning and staining testing process, they can be reinstalled. The board assembly is compressed inside the frame using OEM closed dimensions. After a final inspection, the entire unit is ready for hydraulic testing.
