In recently years , application of new type plastic supply - drain pipe material gets more and more wide spread , it has great progress in our country for production and construction technique of many new type supply - drain pipe materials and component , and relevant material type from zinc - planting - corrugated pipe and iron pipe become to upvc , pp - r , pe - x , pb , pp - c and plastic - alumium , abs and so on 近年来新型塑料给排水管材在建筑给排水中的应用越来越广泛，我国的各种新型给排水管材、管件的生产技术和施工技术有了很大的发展，相应的材料种类也由镀锌钢管、铸铁管变为upvc 、 pp - r 、 pe - x 、 pb 、 pp - c 、铝塑复合管( pap ) 、 abs等等。
Gangsu composite of a gb hot galvanized steel pipes for the matrix , its appearance " never rusting " lining the living standard of polythelene ( pe , cold water ) and apply regardless jubingxi ( ppr hot water ) , gangsu picked up by agents of imports picked up , and use cold water temperature reached 60 degrees , the hot water pipes to 95 degrees 钢塑复合管采用国标热镀锌钢管为基体，其外表“永不生锈”内衬符合生活饮用水标准的聚乙稀（ pe 、冷水）和无规共聚聚丙稀（ ppr热水） ，钢塑拈接采用进口拈接剂，冷水管使用温度达到60 ，热水管可达95 。
