摘要
新型无压埋地用聚乙烯(PE)/聚丙烯(PP)三层壁复合增强管为国内首创产品。该型为内、中(波纹层)、外三层结构,内外壁光滑,环刚度等级高(SN8-16),环柔度、抗冲击强度和折弯强度俱优,连接方便,密封性能强,施工难度小,抗弯曲或沉降性能优异,能显著降低施工成本,缩短工期,提高工程质量,延长工程寿命,减少工程维护成本。与其他类型的结构壁管相比,具有显著的综合性能和应用方面的优势。
New pressureless burying polyethylene(PE) / polypropylene(PP) threelayer composite reinforced pipe are the innovative products nationwide. This model is in inner, middle(corrugated) and outside, three-layer structure, smooth in inside and outside wall,high in ring stiffness grade(SN8-16), strong in impactresistance, easy in connection, good in seal performance, efficient in construction, economical in engineering cost, durable in work. Compared with other types of wall pipes, it has the significant advantages in comprehensive performance and application.
