在建筑中也是可以使用涂塑管来进行疏通使用,同时也是我们在使用涂塑管的时候要注意一些问题,确保正确的使用。
  在新型管材类别中,可应用在建筑给水中的管材,行业内统一称呼为给水管,根据材质不同,称呼上有差别,比方说,用复合材质制造的涂塑管,应用在给水上,就是我厂使用的给水涂塑钢管。选择塑料材质制造的管材就是给水塑料管。
 在给水管道系统上使用的冷、热水管道,应满足下列问题。
  1、保证供水质量满足国家《生活饮用水卫生标准》。管材卫生性能必须通过《生活饮用水输配水设备及防护材料的安全性评价标准》(GB/T17219--1998)的评价要求。
  2、管材的额定工作压力不得小于1.OMPa,水压强试验要求不得小于1.5MPa,并能承受由于水锤所造成的压力冲击。对于管材的使用压力,一般可按生产厂提供的工作压力,即长期使用压力。
  对于外径≤90mm的管,产品设计已考虑2.5的安全系数;外径>90mm的管,产品设计也考虑了2.0的安全系数。厂内短期试验压力则为工作压力的4.2倍,给排水设计中没有必要再除以安全系数。
  3、用于建筑热水管及供暖管道的管材输送介质额定工作温度不得小于70℃,瞬时的最高工作温度为95℃。
  4、用于建筑冷、热水塑料管材的使用寿命和耐久性不得小于50年。
  5、管道的连接方式简便易行,并且安全可靠。
  6、管道系统的管材、管件、支吊卡具、施工安装机具其附配件应配套齐全,满足工程施工安装和使用的要求。
 
In the building, we can also use the coated plastic pipe for dredging. At the same time, we should pay attention to some problems when using the coated plastic pipe to ensure the correct use.
 
In new type pipe material category, can be used in the building water supply pipe, the industry unified name for the water pipe, according to different materials, the name on the difference, for example, with composite material manufacture of coated plastic pipe, the application in the water to the water, is the use of my factory coated plastic pipe. Choose a plastic material to make the pipe is the water supply plastic pipe.
 
Cold and hot water pipes used in water supply piping systems should meet the following requirements.
 
1. Ensure the quality of water supply meets the national standards for drinking water sanitation. The sanitary performance of pipes must pass the evaluation requirements of "safety evaluation standard for drinking water transmission and distribution equipment and protective materials" (GB/T17219--1998).
 
2. Rated working pressure of pipe shall not be less than 1. OMPa, the water pressure test requires no less than 1. 5MPa, and can withstand the pressure impact caused by water hammer. For the use of pipe pressure, generally according to the production plant to provide the working pressure, that is, long-term use of pressure.
 
2 has been considered in product design for pipes with outer diameter ≤90mm. Safety factor of 5; Outside diameter >90mm tube, product design also considered 2. Safety factor of 0. The short-term test pressure in the factory is 4. 2 times, there is no need to divide by the safety factor in the design of water supply and drainage.
 
3. The rated working temperature of pipe conveying medium used for building hot water pipes and heating pipes shall not be less than 70℃, and the instantaneous maximum working temperature shall be 95℃.
 
4. The service life and durability of plastic pipes used for building cold and hot water shall not be less than 50 years.
 
5. The connection of pipelines is simple, easy and safe.
 
6. Pipe materials, pipe fittings, hoisting fixtures, construction and installation machines of the pipeline system shall be fully equipped with accessories to meet the requirements of construction, installation and use.
