| 抽沙管道是主要应用与抽沙和疏浚项目上，输送砂浆的管道。2000年以前主要使用钢管，用作抽沙管道，但是这种管道因为材质自身的原因，重量大，移动不方便，砂浆对管壁的磨损很大。在2000年，被重量更轻的PE管待地，PE管虽然重量轻便了很多，但是耐磨性性能相比钢管，并没有太大的优势。 Sand suction pipeline is the main pipeline for transporting sand mortar and dredging project. Before 2000, steel pipes were mainly used as sand pumping pipes, but because of the material itself, such pipes are heavy and inconvenient to move. Mortar has a great wear on the pipe wall. In 2000, PE pipes were placed on the ground by lighter weight PE pipes. Although PE pipes are much lighter in weight, their wear resistance is not much better than that of steel pipes. 在2006年以后，新型的超高分子量聚乙烯管面世了，这种耐磨管道，主要具备以下优点： After 2006, a new type of ultra-high molecular weight polyethylene (UHMWPE) pipe was introduced. This kind of wear-resistant pipe has the following advantages: 1）极高的耐磨特性 超高分子量高达200万以上，磨耗指数小，耐磨性高于一般的合金钢的6.6倍。大幅度提高了管道的使用寿命。 1) Extremely high wear resistance, ultra-high molecular weight up to 2 million, wear index is small, wear resistance is 6.6 times higher than that of general alloy steel. The service life of the pipeline has been greatly improved. （2）极高的耐冲击性，本产品符合GB1843标准，在现有的工程塑料中本产品的冲击韧性值最高 (2) Extremely high impact resistance. This product meets the GB1843 standard and has the highest impact toughness value among the existing engineering plastics. （3）耐腐蚀性 本产品可以耐烈性化学物质的侵蚀， (3) corrosion resistance of this product can be corroded by strong chemical substances. （4）良好的自润滑性自身润滑很好。摩擦系数小。表面不附着，不结垢。 (4) good self lubrication and good lubrication. The friction coefficient is small. The surface is not adhered to and does not foul. （5）独特的耐低温性 本品耐低温性能优异，可长期在-50℃到80℃的温度下工作。 (5) Unique low temperature resistance. This product has excellent low temperature resistance. It can work in the temperature range from - 50 C to 80 C for a long time. （6）优良的耐开裂性 耐环境应力开裂性最优，抗环境应力开裂>4000h，是PE100的2倍以上。 (6) Excellent cracking resistance and environmental stress cracking resistance are the best. The environmental stress cracking resistance is more than 4000h, which is more than twice that of PE100. （7）安装简便比重仅为钢管重量的八分之一，使装卸、安装时无论是焊接或者是法兰连接均可，安全可靠、快捷方便、无需防腐、省工省力。 (7) Installation is only one eighth of the weight of steel pipe, so that it is safe, reliable, fast and convenient, no need of corrosion protection, labor-saving and labor-saving when loading, unloading and installing, whether welding or flange connection. 抽沙管道，是一个沙场的血管，对整个沙场的顺畅运营起到了至关重要的作用。抽沙管道选择超高分子量聚乙烯管是目前国内沙场的主流选择。具洛阳国润管业有限公司财务部，相关人员分析，目前我们公司出场的抽沙管道，每年能带到10000米左右。使用过超高分子量聚乙烯管做抽沙管道客户，都反应，这种超高管，是耐磨性比PE管要强3倍，比钢管的使用寿命更长了5到7倍，价格也不比钢管贵多少，性价比非常高。 Sand pumping pipeline is the blood vessel of a sand field, which plays a vital role in the smooth operation of the whole sand field. The selection of ultra high molecular weight polyethylene pipe for sand suction pipeline is the mainstream choice in the domestic battlefield. The Finance Department of Guorun Pipe Industry Co., Ltd. of Fuluoyang, the relevant personnel analysis, at present our company's sand extraction pipeline, can take about 10,000 meters a year. Used ultra-high molecular weight polyethylene pipe as sand pumping pipeline customers, all react, this kind of ultra-high pipe, is three times stronger than PE pipe wear resistance, 5 to 7 times longer than the service life of steel pipe, price is not much more expensive than steel pipe, performance-price ratio is very high. |
