Tongda Analysis Machine Is Trustworthy

The ammonia refrigeration pressure pipeline is used for conveying ammonia liquid, ammonia gas by gravity supply and forced pumping by ammonia pump, connecting the low pressure drain tank to the evaporator, and finally returning to the condenser compressor to form a closed circulation system. Because of the flammable, explosive and corrosive nature of the ammonia and ammonia gas it transports, it can cause structural defects in the pressure pipe during long-term use.
In recent years, ammonia leaks and ammonia pipeline explosion accidents have occurred frequently, causing huge economic losses, and may cause casualties to surrounding personnel. The pressure pipeline is an important part of the ammonia refrigeration system, and its long-term low temperature operation is very important. After investigation, it was found that most of the explosion of pressure pipes was caused by defects caused by long-term use of internal wall corrosion and consumption of containers, devices and pipes.
The inspection of the inner wall of the ammonia refrigeration pressure pipeline must be carried out by purging, replacing and cleaning processes to ensure that the pipeline is in a suitable state to be inspected, which will inevitably lead to long inspection time and large economic loss. Therefore, under the premise of not damaging the overall structure of the pressure pipeline, it is particularly important to explore the effective inner wall defect detection technology, and the importance of the X-ray real-time imaging inspection equipment is thus apparent.
The X-ray real-time imaging inspection equipment has clear imaging and can directly detect the internal defects of the pressure pipeline. Whether it is produced by the manufacturer online or used for a long time, the X-ray real-time imaging inspection equipment can be used to detect the weld seam inside the pipeline. Defects such as cracks, shrinkage cavities, holes, corrosion, etc. Today, X-ray real-time imaging inspection equipment has been widely used in the internal defects of ammonia refrigeration pressure pipelines, and has achieved very good results in actual inspection.
Tongda Technology series X-ray real-time imaging inspection equipment is a non-destructive testing equipment for standard industrial fields. It can meet the testing needs of most pressure pipelines, pressure vessels and other products.
