在建筑中也是可以使用涂塑管來進行疏通使用,同時也是我們在使用涂塑管的時候要注意一些問題,確保正確的使用。
  在新型管材類別中,可應用在建筑給水中的管材,行業內統一稱呼為給水管,根據材質不同,稱呼上有差別,比方說,用復合材質制造的涂塑管,應用在給水上,就是我廠使用的給水涂塑鋼管。選擇塑料材質制造的管材就是給水塑料管。
 在給水管道系統上使用的冷、熱水管道,應滿足下列問題。
  1、保證供水質量滿足國家《生活飲用水衛生標準》。管材衛生性能必須通過《生活飲用水輸配水設備及防護材料的安全性評價標準》(GB/T17219--1998)的評價要求。
  2、管材的額定工作壓力不得小于1.OMPa,水壓強試驗要求不得小于1.5MPa,并能承受由于水錘所造成的壓力沖擊。對于管材的使用壓力,一般可按生產廠提供的工作壓力,即長期使用壓力。
  對于外徑≤90mm的管,產品設計已考慮2.5的安全系數;外徑>90mm的管,產品設計也考慮了2.0的安全系數。廠內短期試驗壓力則為工作壓力的4.2倍,給排水設計中沒有必要再除以安全系數。
  3、用于建筑熱水管及供暖管道的管材輸送介質額定工作溫度不得小于70℃,瞬時的最高工作溫度為95℃。
  4、用于建筑冷、熱水塑料管材的使用壽命和耐久性不得小于50年。
  5、管道的連接方式簡便易行,并且安全可靠。
  6、管道系統的管材、管件、支吊卡具、施工安裝機具其附配件應配套齊全,滿足工程施工安裝和使用的要求。
 
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.
