China PVC pipe has developed rapidly over the years, with an annual rate of increase of 8%, and an annual rate of increase of 2%. In plastic pipes, the amount of PVC pipe used has been far ahead, it is widely used in water supply and drainage pipes.
Product innovation has yet to be improved - because the skills are relatively sophisticated, PVC water pipe in recent years, product innovation is not invested, the new product is relatively small, the general market products, high-skilled, high value-added products, similar General products, medium-grade low-volume products accounted for the majority of advanced products less.
The impact of lead-free on PVC-U pipelines - Probably facing, the PVC-U drinking water pipe to use non-lead salt heat stabilizer rules on the PVC pipe industry has a greater negative impact. Although the relevant part of the industry associations and some production companies have made many efforts to convene a special press conference, the use of the media to promote the whole situation gradually rationalized, but because some users still do not know the real situation, PVC-U The rate of increase in the amount of drinking water pipe is less than the uniform increase level, and there is also a potential negative impact on the use of other PVC-U pipes.
Expand the use of the scope of the market to implement the work to be improved, the use and supporting skills to be further improved - industry and product promotion, science and other aspects of the operation is not in place, affecting the rational use of plastic pipes and the use of the expansion. Industry associations have yet to be concerned about the operation, the promotion of efforts to be strengthened. At present, the use of the product market will be set in a limited number of areas, as well as the opportunity to open up new use of the market. Some products use the matching skills are not available, and some product design, construction, testing and other standardized operations is lagging behind.
The market is not standard, and some products of low quality products, affecting the healthy development of the industry - because the plastic pipe market is not standard, and some buyers are not the end of the product users, do not pay attention to brand and quality, the formation of different quality on the market Of the products exist, and even some of the low price of the product is very good to sell, and PVC-U tube is still more serious. It is understood that a county-level regional PVC-U production companies have more than 500, and the vast majority of family workshops, the quality of the situation can be imagined. PVC-U pipeline capital, the price of materials accounted for about 70%, a single company after reducing the wall thickness, a lot of calcium carbonate and other ways to reduce product costs, the formation of low quality products. There are more than two different brands of trademarks, the use of low-grade processing equipment, drinking water pipe selection of lead salt stabilizer production and other methods to reduce costs, damage the interests of consumers, the industry's promise to ruin.
Construction quality should be further improved - PVC-U pipeline engineering quality depends largely on the level of construction, good products and contact construction to ensure that the pipeline system engineering outstanding operation. Some of the technical staff in the short of professional training, in practice, follow the method of metal pipe design and construction, there is no standard construction, rough construction and other conditions, did not give full play to the PVC-U pipe technical and economic functions, and even the formation of the pipeline damage. Some users to the current still do not know how the plastic pipe according to the procedures for construction, supervision and so on all the knowledge.
