功能特点
Functional characteristics
1、具有优良的抗腐蚀性能
1. Excellent corrosion resistance
不要阴极防腐保护及其它防腐措施，不会对水和其它介质产生二次污染。产品使用寿命长。
Do not use cathodic protection and other anti-corrosion measures, and do not cause secondary pollution to water and other media. The product has a long service life.
2、重量轻强度大
2. Light weight and high strength
管道重量仅占同规格、同长度球墨铸铁管的1/4，水泥管道的1/10。运输装卸方便，易于安装。
Pipeline weight is only 1/4 of nodular cast iron pipes of the same specification and length, and 1/10 of cement pipes. Transportation, loading and unloading are convenient and easy to install.
3、单根管道长度长
3. Length of a single pipe
减少管线接头，加速安装速度，提高整条管线质量。
Reduce pipeline joints, accelerate installation speed, improve the quality of the whole pipeline.
4、管壁内壁光滑
4. Smooth inner wall of pipe
减少流阻、提高流速、降低能耗。用较小口径的管道输送同等流量的流体，与同规格钢管相比可提高流量的10%左右；不结垢，长期使用不降低流速。扰和重蚀环境中电缆的防护都有较好效果。
Reduce flow resistance, increase flow rate and reduce energy consumption. The same flow rate can be increased by about 10% compared with the same size steel pipe by conveying the same flow rate with smaller diameter pipeline, and the flow rate can not be reduced by long-term use without scaling. The protection of cables in disturbing and re-eroding environments has good effect.
