China's PVC pipe has developed rapidly in recent years, and the use of PVC pipe has always been far ahead. It is widely used in water supply and drainage pipes.The expansion of application scope and market implementation work needs to be improved. The application and supporting skills need to be further improved. The industry and product promotion, science popularization and other aspects are still not in place, which affects the rational use of plastic pipes and the expansion of application scope.The relevant work of the trade associations has yet to be improved, and the promotion of publicity needs to be strengthened. At present, the market for the application of products will be concentrated in a limited number of areas, and there is also the opportunity to open up new markets for application. Some of the supporting skills for product use are not complete, and some standardization operations such as design, construction, and inspection are relatively lagging.
In terms of product innovation, there is still room for improvement. In recent years, PVC water supply pipes have not invested much in product innovation. There are relatively few new products. There are many general products on the market, few high-skilled and high-value-added products, similar general-purpose products, and low-grade products. The products account for the majority and the advanced products are few.
The impact of the ban on lead on PVC-U pipelines is based on the fact that the rules for the use of non-lead salt heat stabilizers in PVC-U drinking water pipes have a significant negative impact on the PVC pipeline industry. Some users still don't know the true situation. The increase rate of PVC-U drinking water pipe usage is less than the uniform increase level, and there are potential negative effects on the use of other PVC-U pipes.
The market is not standard: the quality of the company's products is low, which affects the healthy development of the industry. Because the plastic pipe market is not standard, the purchaser is not the end user of the product, and does not pay attention to the brand and quality, forming products of different quality in the market, and even local quality. Products with low price differences are very good for sale. In the cost of PVC-U pipelines, the price of the materials accounts for about 70%. Individual companies have reduced the wall thickness and increased the amount of calcium carbonate to reduce the cost of the products, resulting in low quality products.
The construction quality of the project should be further improved. The quality of the PVC-U pipeline project depends largely on the construction level. Good products and proper construction capabilities ensure the outstanding operation of the pipeline system engineering. A good skilled professional, using the right design and construction methods, can fully utilize the existing functions of the PVC-U pipeline.
