New technologies bring new challenges to the plastic pipe industry

HC Plastics News: “Scene setting: the world without plastic is unimaginable; 60 million tons of plastic products are invested every year in the European market; about 25 million tons of plastic waste is produced every year in Europe; 75% of plastic waste is burned or filled ......"Tony from the European Plastic Pipe Fittings Association (TEPPFA) brought European plastics at the 5th China (2017·Hangzhou) International Plastic Pipe Exchange Conference held in Hangzhou, Zhejiang from October 26th to 27th. When the pipeline industry used the practices and standards of recycling, it received high attention from the participants. Many representatives not only took notes seriously, but also took out the mobile phone and took the corresponding PPT (slide).

The main purpose of this global plastic pipe exchange event, co-sponsored by China Plastics Processing Industry Association Plastic Pipeline Professional Committee (CPPA) and International Plastics Pipe Conference Association (PPCA), is to further promote the plastic pipe industry through information and technology exchange. The level of production and application promotes the healthy development of China's and international plastic pipe industries and enhances the overall competitiveness of the industry.

“This conference is an extension of the 18th International Plastics Pipeline Conference in 2016 (Berlin, Germany) and the fifth international plastics pipeline industry event in China.” Chairman of the Plastic Pipeline Professional Committee of China Plastics Processing Industry Association Zhang Jianjun said that from the capital Beijing (2009, 2011) to the starting point of the ancient Silk Road, Xi'an (2013), the international metropolis Shanghai (2015) and then to the beautiful West Lake (Hangzhou) (2017), through international exchanges The technical level of China's plastic pipe industry has promoted the continuous progress of the industry.

“Currently, China is the world's largest market for plastic pipe systems. China's '13th Five-Year Plan' focuses on water, water efficiency and water quality. It is believed that the long service life of plastic pipe products is long. With the advantages of excellent quality, the plastic pipe industry will be able to achieve all the goals through unremitting efforts.” Zoran, president of PPCA's 18th (Berlin, Germany) International Plastics Pipeline Conference, said that since the China International Plastic Pipeline Exchange Conference China's plastic pipe industry has developed rapidly. On the one hand, the industrial concentration of large-scale plastic pipe companies continues to increase; on the other hand, smaller plastic pipe companies continue to die. The former is the result of product quality driving, and the latter is caused by intense competition in production costs. Another trend worthy of attention is the gradual development of plastic pipe products to more complex multi-layer pipes. The performance of China's plastic pipe products is improving day by day, greatly improving the quality of construction and municipal construction.

New technologies bring new challenges to the industry

According to the statistics of the Plastic Pipeline Professional Committee of China Plastics Processing Industry Association, China's plastic pipe industry has maintained sustained and stable development under the support of relevant national policy support and market demand. The output has increased from 11 million tons in 2012 to 2016. 14.36 million tons. In recent years, the export volume, export volume and average unit price of plastic pipes have maintained a relatively steady growth, and the export volume has increased from 480,000 tons in 2012 to 580,000 tons in 2016. At present, the output of the top 20 companies in the industry has exceeded 40% of the total output.

Wang Zhanjie, secretary-general of the Plastic Pipeline Professional Committee of China Plastics Processing Industry Association, said that technological progress is the main driving force for the innovation and development of the industry. In the continuous development of the plastic pipe industry, technological innovation and technological progress have played an important role. However, China's plastic pipe industry still has insufficient attention to concept innovation. Some enterprises still focus on product imitation, lack of basic technology research; some enterprises have low investment in science and technology research, and relatively low-tech and high value-added products. The existence of problems is not conducive to the new challenges brought by new technologies in enterprises and industries.

The domestic and foreign participants attending the meeting believed that with the development and advancement of technology, the application fields of plastic pipes have been expanding, and many new materials, new technologies, new equipment, and new products have been developed, in addition to the traditional water supply and drainage fields. There are also many new field applications and products, and the emergence of new technologies has brought new challenges to the development of the industry.

At the exchange meeting, Gao Lixin, chief engineer of the Science and Technology and Industrialization Development Center of the Ministry of Housing and Urban-Rural Development, introduced the development of the application technology of the central heating and prefabricated thermal insulation plastic pipe engineering; Pierre of the European PVC Pipeline Association introduced the progress and advantages of the PVC pipeline; Professor Ma Baosong, professor of the University of Geosciences (Wuhan) and director of the Sino-US Joint Research Center for Non-excavation Engineering, introduced the application of trenchless technology and plastic pipes in non-excavation projects, and the exchange of many new technologies between China and foreign countries not only demonstrated plastic pipes. The vast application space also makes the opportunities and challenges of its development clearer.

Quality competition is global competition

With the advancement of society and the continuous improvement of the quality awareness of the application field, the quality level of plastic pipe products has received more and more attention. “Quality is a key element of market competition. Whether it is a new market, a new consumer or a potential obstacle in trade, quality is of paramount importance,” said Ricardo, director of the AENOR-CEIS certification testing agency in Spain.

Wang Zhanjie also said that as the world's largest producer and application of plastic pipes, cultivating technology-driven and quality competitive advantages is an important basis for safeguarding and promoting the sustainable development of China's plastic pipe industry. Like other “Made in China”, the plastic pipe industry urgently needs to achieve industrial upgrading, moving from “big country” to “powerful country”. The whole industry should continuously improve the integrity and self-discipline system to guide the healthy development of the industry; promote the implementation of standardization strategy and improve product quality. Establish brand awareness, increase product competitiveness, promote the improvement of product quality in the industry, and promote industrial upgrading with quality improvement.

The standard is the basis of quality and the “standard rope”. Participants have conducted in-depth exchanges on the global standards related to plastic pipes. For example, the technical manager of the European Plastic Pipe Fittings Association, Pitt introduced the latest progress of European PVC-O plastic pipe system standards, PVC-O plastics. The EN standard for piping systems is expected to be finalized by the end of 2017. This system standard specifies the joint connection requirements for PVC-O pipes, PVC-O pipe fittings, valves, joints and other plastic and non-plastic materials (metal, concrete) components.

The participants agreed that the past development of China's plastic pipe industry relied too much on the expansion of production. The rapid development of the industry also brought about relatively serious problems of homogenization overcapacity. In excess, overcapacity intensified market competition. Sexuality leads to more disordered and low-price competition in the market, resulting in uneven quality. "In order to get rid of the status quo, China's plastic pipe industry must develop with quality, firmly establish the idea of ​​'quality first', strengthen the quality awareness and management level of the enterprise, and gradually realize the transformation from a big plastic pipe country to a strong country." Wang Zhanjie said.
