According to data from the Plastic Pipe Special Committee of the China Plastics Association, in 2016, China's total output of plastic pipes reached 14.36 million tons, a year-on-year 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 average demand for plastic pipes in the housing urban and rural construction industry during the 13th Five-Year Plan period was 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.

The national standards for plastic pipes in China are mainly formulated with reference to international standards. After more than 20 years of development, the national standard system for plastic pipes in China has been basically established. According to incomplete statistics, there are currently more than 70 industry standards in China's plastic pipe industry. 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, plastic pipe standardization has problems such as standard management 'soft', standard system 'chaos', and standard level 'low'. ".

Take the industry standard "Steel Belt Reinforced Polyethylene (PE) Spiral Bellows for Underground Drainage" as an example. In June 2006, the Ministry of Construction issued industry standards for the use of this product. "Steel belt bellows 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 before, and naturally there is no industry standard to refer to." Wu Zhiguo, general manager of Sichuan Huangsheng Pipe Industry Co., Ltd., interviewed by reporters That being said.

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

"The drafting of the standard technical indicators has referenced some of the indicators of other pipe materials, and there are also data indicators that companies can get back in the market." According to Wu Zhiguo, there was no precedent for reference at the time. 》 The value of the technical indicators formulated is 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 all parties in production and application under the organizational leadership of the Standardization Institute of the Ministry of Construction at the time. It was the quality criterion for the performance of this product, and it was also for all parties to "establish the best order The consensus reached on "Best Benefit" 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, and the rapid development of such pipes has been promoted.

At the 2017 annual meeting of the China Plastics Association Plastic Pipe Special Committee, the special committee announced the list of units participating in the "Steel Belt Reinforced Polyethylene Spiral Bellows Quality Assurance Alliance", which means that China's plastic pipeline "Quality Assurance Alliance" "The model goes one step further. The first working meeting of the protection alliance in 2017 was held in Beijing a few days ago. The alliance hopes to solve the existing technical problems of products through the improvement of equipment and processes among members, the improvement of testing and quality assurance measures, establish existing technical standards and self-discipline systems, improve the quality of steel pipe products, advocate the establishment of market reputation, and adopt Measures supervise the implementation of alliance product standards by member companies and promote the healthy development of the 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 of the alliance standard 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 should be drafted as soon as possible.

Wang Zhanjie, vice chairman of China Plastics Processing Industry Association and secretary general of the China Plastics Association Pipeline Special Committee, told reporters: "We need to supplement and improve the standards of the China Plastics Association group. To solve the lack of coverage of existing standards, some standards Issues such as improvement are still needed. 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 the competitiveness of the industry.
