China PVC pipes have been carried out relatively quickly in recent years, with an annual addition rate of 8%, and an annual increase rate of 2%. Among plastic pipes, the amount of PVC pipes has always been remote, and it is widely used in water supply and drainage pipes.

The renovation angle of the production works needs to be advanced because the technical means are relatively sophisticated. In recent years, the investment in the renovation angle of PVC water supply pipes has not been large, and there are few new products. As usual, there are many products on the market, high-skilled, high-value-added products Most of the same general-purpose products, middle-lower manufactured products, and low-grade products are few.

The impact of the ban on lead on PVC-U pipes may be faced squarely. The application of non-lead salt the most different to modified plastic PVC-U drinking water pipes will have a greater impact on the PVC pipe industry. Although the relevant departments, industry associations, and some production companies have made a lot of effort, by the way, a press conference was held and the media was used to promote the situation. The whole situation was gradually rationalized, but because some users still did not understand the actual environment. The growth rate of the consumption of PVC-U drinking water pipes is less than the average addition level, and there is also a frontal influence on the use of other PVC-U pipes.

Expansion of use limitations, market promotion work needs to move forward, the use and supporting martial arts need to further complete the industry follow-up product announcements, scientifically modified plastics, and other perspectives are not in place, which affects the rational use of plastic pipes and the expansion of application scope. The irrelevant work of the industry associations needs to be improved, and the advocacy needs to be strengthened. At present, the application market of products is still concentrated in a few areas, and there are opportunities to open up new application markets. The supporting skills used in some productions are not complete, and the standardized homework of design, construction, and testing of some productions lags behind.

The market is not standard, and some companies have low quality and quality, which affects the healthy development of the industry. Because the plastic pipe market is not standard, some buyers are not the end-users of the products, and they do not favor the brand and quality, forming the market for modified plastics. Products of consistent quality are available together, which makes some products with low price differentials very easy to sell, and PVC-U pipes are still relatively cruel. According to familiarity, there are more than 500 various PVC-U production companies in a county-level area, and most of them are family workshops, and the quality environment is incredible. In the capital of PVC-U pipelines, the quotation of materials accounts for about 70. A single company reduces the cost of manufacturing products by reducing the wall thickness and increasing the calcium carbonate a lot, resulting in low-quality products. Another company chooses more than two grades of unqualified quality, uses the lowest-ranking processing facilities, and uses lead-salt sticking agents for drinking water pipes to reduce profits. The death of modified plastics has reduced the rights of consumers and relaxed the industry. promise.

The construction quality of the project should be further completed. The quality of the PVC-U pipeline project depends very much on the construction level. Good product production and consistent construction skills ensure the enhanced operation of the retention system project. In some projects, the technically strong personnel lack professional training, and the theoretical operation is based on the metal pipe method for planning and construction. There are conditions such as non-standard construction and crude halogen construction, and the magical skills of PVC-U pipelines are not fully utilized. Cause poor damage to the pipeline. Some users are still unfamiliar with the construction and supervision of plastic modified plastic pipes according to regulations or extensive common sense.
