As a UHMWPE Pipe Manufacturers, share with you. Dredging pipes, sand pumping
pipes, and mud pipes will all encounter the problem of wear-resistant pipe
blockage during construction, which will affect the progress of the project.
There are many factors that affect the blockage of UHMWPE Pipe. Including the
size, shape, concentration, specific gravity of the solid particles in the mud
and mortar, the roughness of the pipe wall and the viscosity of the fluid, etc.
The main factors are as follows:
UHMWPE Pipe
(1) Mud and mortar particle size: The larger the particle diameter of the conveying medium, the greater the sedimentation speed of the particles in the mud, which will cause the pipeline to block, and then increase the resistance loss of the sand pumping pipeline, dredging pipeline, and mud pipeline. Therefore, reducing the particle size of the slurry can effectively improve the pipeline blockage and reduce the pipeline transportation resistance of the slurry.
(2) Pipe surface roughness: The pipe inner wall surface is rough, and the resistance coefficient of the pipe will increase. Therefore, when piping, you should choose ultra-high molecular weight polyethylene pipe with a smooth surface to effectively reduce the resistance of the pipe.
The material selection of the dredging pipe, sand pumping pipe, and mud pipe is very important. UHMWPE Pipe, impact resistance, self-lubricating, anti-adhesion, sanitary and non-toxic, shock absorption, good noise reduction effect, good environmental stress cracking resistance, light weight, etc. , It is very suitable for wear-resistant pipelines such as dredging pipes, sand pumping pipes and mud pipes.
UHMWPE Pipe transporting tailings and other solid materials has high requirements for the wear resistance and anti-corrosion performance of the pipeline, and UHMWPE Pipe can be well adapted to the needs of all aspects of tailings transport pipelines.
1. Very high wear resistance
The unique molecular structure of UHMW-PE products makes it highly resistant to sliding friction. The wear resistance is higher than that of general metal materials, which can greatly increase the service life of the pipeline.
2. High impact resistance
Among the existing engineering plastics, the impact toughness of this product is high. Many materials will crack, break, break, or surface stress fatigue in the impact of severe or repeated explosions. According to the GB1843 standard, this product has been subjected to cantilever beam impact test to achieve no damage.
3. Excellent chemical stability
UHMWPE Pipe is resistant to aggressive chemical substances. Except for some strong acids that slightly corrode at high temperatures, it is not corroded in other lye and acid solutions. It can be used in concentrated hydrochloric acid with a concentration of less than 80%, and its performance is quite stable in sulfuric acid with a concentration of less than 75% and nitric acid with a concentration of less than 20%.
