以高密度聚乙烯（PE）为基体，用表面涂敷粘接树脂的钢带成型为波形作为主要支撑结构，并与聚乙烯材料缠绕复合成整体的双壁螺旋波纹管。 |
Based on the high density polyethylene(PE),make the shaped steel strip which is coated with the adhesive resin on the surface as the main supporting structure,entwine with polyethylene materials,to form the whole Dual Wall Helical Bellows in combination. |
1、钢带增强管材耐腐蚀、耐酸碱性强；
2、管材环刚度高、重量轻、安装施工方便；
3、由于采用熔融塑料相互连接形成无缝内壁，故可靠性强；
4、管材可采用多种连接方式，简便易操作。 |
1.Steel strip may strengthen the corrosion resistance of pipes,high acid and alkali resistance;
2.Ring stiffness of pipes is high,light in weight;it is convenient for installation and construction;
3.Due to the reason of adopting the melting plastic for connectiong with each other forming the seamless interior wall,it is highly reliable;
4.Pipe may adopt various connecting method,it is easy and convenient for operating. |
