青龙管业耐热聚乙烯(PE-RTⅡ型)供热管道推介会近日在银川举行。以耐热聚乙烯为主要材料生产的复合塑料供热管道,因为具有耐高温、耐冲击、耐腐蚀、寿命长、免维护等优势,受到了来自各市、县(区)的建设及供热相关单位代表的关注与青睐。该供热管道的推广与使用,将使供热管网进入“以塑代钢”时代,并带来一场二次热力管道的全新革命,而供热“老大难”问题将会得到有效解决。长久以来,我国的供热管道基本是钢管,其优点是强度
Qinglong pipe heat-resistant polyethylene (PE-RT Ⅱ-type) heating pipe promotion will be held recently in Yinchuan. Due to the advantages of high temperature resistance, impact resistance, corrosion resistance, long service life, maintenance-free and so on, the composite plastic heating pipe which is made of heat-resistant polyethylene as its main material is affected by the construction and heating from various cities and counties (districts) Unit representatives of the attention and favor. The promotion and use of the heating pipeline will bring the heating pipe network into an era of “plastic substitution of steel” and will bring about a brand new revolution of the secondary thermal pipeline. Will be effectively resolved. For a long time, our country’s heating pipe is basically a steel pipe, the strength is strength
