High molecular weight polyethylene pipes are primarily characterized by their high wear resistance and strong corrosion resistance. However, in actual conveying, the factors affecting wear are not singly present but rather a combination of various elements. Therefore, even with the same material and pipe material for the same material, the degree of wear can vary due to different conveying conditions. The main factors influencing this include:
1. Characteristics of the material being conveyed; such as particle size, shape, solid content, hardness, moisture content, breakage rate, and adhesiveness, etc.
2. Product Material: Such as the molecular weight of polyethylene pipe materials, hardness, surface smoothness, inner diameter, and pipe layout.
3. Transfer Conditions: Including the velocity, temperature, and flow state of the conveying medium.
When using ultra-high molecular weight polyethylene pipes as tailings pipes, it is important to note that the gradient of the tailings pipeline should not be too steep. If the pipeline gradient is too steep, coarse tailings particles may not be easily transported, leading to their accumulation and cyclic movement within the pipeline, which can cause rapid wear. Therefore, it is advisable to avoid large ore blocks entering the tailings to reduce the pipeline diameter, ensuring a smooth operation of the tailings transportation system. Reducing water hammer and friction can significantly extend the lifespan of the high molecular weight tailings pipes.
