PE pipe and UPVC pipe in performance contrast what are the advantages?
Since the 80 s, the state vigorously promote application of upvc pipe, and a series of policy, system, standard, also accumulated a lot of experience. Development to today, have perfect product standard, testing method and testing means, construction engineering technology standard and so on, and unified the product size and quality indicators, implements the interchangeability of the product. It illustrates the development of PVC water supply pipeline has entered the mature period, and construction quality has the guarantee product quality, to ensure that the use of PVC water supply pipeline.
And feed with PE pipe international standards (ISO4427) officially released until 1996. Our reference ISO4427 wrote in 1999, the national standard GB/T13663, and promulgated in 2000, but has standard of PE pipe, engineering technical specification and the continued to improve. This shows that domestic PE pipe quality is not stable, pipe fitting is not incomplete, thus unable to ensure production, construction of quality.
