超高分子量聚乙烯钢塑复合管材、管件是以超高分子量聚乙烯管材作耐磨或耐腐蚀的内衬材料，以钢管（焊管、螺旋管、无缝管等）作耐压保护外管，二者通过专门的工艺装备复合而成。产品在保留UPE的各项性能优势的基础上，又具有以下新的特点：
一：可以承受更高的压力：复合管材承压可达5MPa--10MPa，可满足井下充填、尾矿输送、原油输送等各种高压管道的使用要求。
二：可以承受高的温度：有了钢管的保护支撑，可以克服UPE管的高温变形，工作温度可以提高到80℃左右。
三：克服了塑料管易弯曲、下垂的缺陷，作为车间内工艺管道或露天架空管道会更美观。
四：配套技术成熟：公司已申报“超高分子量聚乙烯钢塑复合耐磨管件”和“用于超高钢塑复合管道的伸缩节”两项实用新型专利技术。
