我国塑料管材发展趋势概述

Developing trend of plastic pipes in China

我们知道,塑料埋地管逐步取代传统管材已成为不可抗拒的趋势。更为值得重视的是:PE管将取代PVC管,结构管将取代实壁管。而直接挤出成型HDPE大口径双壁波纹管将成为主要管材。

It is an irresistible trend for underground plastic pipes to gradually replacetraditional pipes. The following two trends also need great attention: one is that PEpipe is replacing PVC pipe; the other is that structural pipe is replacing solid-shellpipe, and extrusion HDPE large-diameter twin-shell corrugated pipe will become amajor product.
