——塑料管塑料管的推广应用主要以UPVC塑料管为主,并大力发展新型塑料管。 1.2000年,全国新建住宅的建筑室内排水管道系统50%采用塑料排水管,电线穿线护管50%采用塑料管,外墙雨水管路20%采用塑料管,约需各种管材,管件总计10万吨左右。针对住宅建筑标准的提高,进行建筑室内上下管、供暖管、热水管道暗敷柔性塑料管的工程示范,稳步推广应用。 2.扩大城市给水塑料管的工程示范,2000年,全国新建城市供水管道(直径400毫米以下管道)30%采用塑料管,村镇供水管道60%采用塑料管,约需用UPVC塑料管17万吨左右。有条件的省、市开展城市下水道、城市煤气管道的塑料管应用试点示范。——塑料门窗
- The promotion and application of plastic pipe plastic pipe is mainly UPVC plastic pipe, and vigorously develop new plastic pipe. 1. In 2000, 50% of the building’s indoor drainage pipe system for new residential buildings in China was made of plastic drain pipe. 50% of the cable threading protection pipe was made of plastic pipe. 20% of the outer wall rainwater pipe was made of plastic pipe and required various pipe materials. The total pipe fittings were 100,000 tons. about. In response to the improvement of residential building standards, the construction demonstration of the upper and lower pipes, heating pipes, and hot-water pipes underlaying flexible plastic pipes in the building are being steadily promoted and applied. 2. To expand the engineering demonstration of urban water supply plastic pipes, in 2000, 30% of newly-built urban water supply pipes (those with a diameter of 400 mm or less) were plastic pipes, 60% of rural water supply pipes were plastic pipes, and approximately 170,000 tons of UPVC plastic pipes were used. about. The provinces and municipalities with the conditions to carry out pilot demonstrations of plastic pipe applications for urban sewers and city gas pipelines. - Plastic doors and windows
