China's plastic pipe industry is preparing group standards


According to the data of the China Plastics Association Plastic Pipeline Special Committee, in 2016, the total output of China's plastic pipes reached 14.36 million tons, an increase of 4.06%. Gao Lixin, chief engineer of the Science and Technology Development Promotion Center of the Ministry of Housing and Urban-Rural Development, introduced at the plastic pipe industry exchange meeting held in 2017 that the demand for plastic pipes in the housing and urban-rural construction industry during the “13th Five-Year Plan” period averaged about 5 million tons per year. He said that what corresponds to the development of the industry is whether the standardization of the industry is compatible with the development of the industry.


China's national standards for plastic pipes are mainly formulated with reference to international standards. After more than 20 years of development, China's national standard system for plastic pipes has been basically established. According to incomplete statistics, there are currently more than 70 industry standards for the plastic pipe industry in China. Dai Chunsheng, secretary-general of the Pipeline Structure Professional Committee of China Engineering Construction Standardization Association, pointed out at the plastic pipe industry exchange meeting: "At present, there are problems such as standard management 'soft', standard system 'chaos' and standard level 'low'. ".


Take the industry standard of "Steel Belt Reinforced Polyethylene (PE) Spiral Bellows for Buried Drainage" as an example. In June 2006, the Ministry of Construction issued the industry standard for the use of this product. “Steel belt corrugated pipe technology is relatively advanced in China. At that time, it was a new technology research and development product in China. The market did not have this thing in the past. Naturally, there is no industry standard for reference.” Wu Zhiguo, general manager of Sichuan Huangsheng Pipe Industry Co., Ltd., was interviewed by reporters. If so.

It is understood that the "standard" is issued by the Ministry of Construction, which stipulates the definition of steel strip reinforced polyethylene (PE) spiral corrugated pipe, raw materials, pipe structure and connection methods.

"The drafting of standard technical indicators, with reference to some other indicators of other pipes, there are also data indicators that enterprises have returned in the market practice." According to Wu Zhiguo, there was no precedent for reference, for insurance, "Steel Belt Corrugated Pipe 2006 Industry Standard The numerical values ​​of the technical indicators formulated are generally high, which is equivalent to presetting an advance value.

It is understood that the 2006 standard was the basic criterion for the coordination of production and application under the leadership of the organization of the Ministry of Construction Standardization Institute. It was the quality criterion for the performance of this product, and it was also the time for all parties to establish the best order and obtain The consensus reached on the best benefits has played a regulatory role in the production of this product. In recent years, under the guidance of the national policy of energy conservation and emission reduction, the implementation of CJ/T225-2006 product standards has been promoted, which has promoted the rapid development of such pipes.

At the annual meeting of the China Plastics Association Plastic Pipeline Special Committee in 2017, the special committee announced the list of units participating in the “Steel Belt Reinforced Polyethylene Spiral Corrugated Pipe Quality Assurance Alliance”, which means China’s plastic pipeline “Quality Assurance Alliance” "The model goes one step further. The first working meeting of the Safeguards Alliance was held in Beijing a few days ago. The alliance hopes to solve the existing technical problems of the products through the improvement of equipment and process among members, the improvement of testing and quality assurance measures, solve the existing technical problems of the products, establish technical standards and self-discipline systems, improve the quality of steel strip products, and advocate the establishment of market reputation. Measures to supervise member companies to implement alliance product standards and promote the healthy development of steel belt reinforced polyethylene spiral corrugated pipe industry.

It is reported that the participants discussed the preparation of the "Steel Belt Reinforced Polyethylene (PE) Spiral Bellows" alliance standard. The draft standard of the alliance is higher than the current construction industry standards in some technical indicators. The alliance standard will be further developed after the meeting. The verification and other work will form a consultation draft as soon as possible.

Wang Zhanjie, vice chairman of the China Plastics Processing Industry Association and secretary-general of the China Plastics Association Pipeline Special Committee, told the reporter: "We must formulate the standards of the China Plastics Association to supplement and improve the level. The existing standards are not covered enough, and some standards are There is still a need to improve and other issues. The plastic pipe industry must constantly improve itself, work hard on product quality, innovation and service, and strengthen its work in product standardization and quality assurance alliances to enhance industry competitiveness."
