장기 내수압 특성을 갖는 고강도 내충격 PVC관(HIVP)의 신뢰성 평가

1936 PVC is produced in Germany since the first 70 years in international and domestic long-life, the 55-year history, but about the international standards based on the assumed situation is being evaluated. Recently in Japan, as well as the existing water supply, sewerage sector, the building interior drainage and storm drains, including the performance evaluation results are used in various fields of real rigid PVC pipe for long-life PVC pipes valued in Japan. Joint Tube Association According to the report written by long-term use in evaluation of product properties by using the elapsed years reduced the number check it yielded no more than 50 years is considered long-life secured. Thus, the domestic water pipe products developed by the imPact assessment in the long-term Hydrostatic pressure or water pressure over 11,001,000 hr based on 50 years as the existing water pressure of 25 ㎫ 26 ㎫ higher than the properties to secure the durability of more than 50 years were obtained. Recently in the mineral aggregate containing PVC is used in DH pipe for high-rise buildings and water pipes, heat exchange systems such as C-PVC Pipe PVC products have a variety of products being developed are expected to increase demand.
