Products Description
NO welding HDPE Pipe with both end flange is a high-density polyethylene pipe commonly used in fields such as hydraulic transportation and chemical transportation. With the increase of transportation time and service life, dirt and sediment are prone to accumulate inside the pipeline, resulting in a decrease in flow rate and an increase in resistance, which affects the efficiency of equipment operation. Therefore, regular cleaning and dredging of HDPE pipes are particularly important.
The traditional dredging method usually adopts the welding method, welding a larger diameter blind plate at the pipeline mouth, and then opening holes on the blind plate to spray high-pressure water or air for cleaning and dredging. However, the operation of welding blind plates is relatively complex, requiring professional welding tools and techniques, and welding blind plates can cause certain damage to the pipeline mouth.
In recent years, with the continuous advancement of science and technology, a new type of non welded dredging method has gradually been widely used for dredging HDPE pipes, especially in special fields such as nuclear power plants and food production.
This non welding dredging method involves spraying a polymer material inside the pipeline to form a smooth, thin, and uniform coating, and then flushing and dredging it using high-pressure water or eddy currents. This method can effectively clean the dirt and sediment inside the pipeline, and is easy to operate without causing damage to the pipeline, avoiding the disadvantages of welding blind plates.
