(www.haihuidaxiangsu.com) is specialized in "PVC profiles, seals, ABS extrusion profiles, PVC raw material" of the enterprise, the company of "honesty, hard service" concept, for You provide the most quality products and services. Welcome to inquire! Contact: Zhao Shuang. From the early 1980s, the country to promote the use of upvc pipe, and developed a series of policies, systems, standards, and has accumulated a lot of experience. Development today PVC molded fittings, already has a complete product standards, test method standards and testing methods, construction engineering and technical specifications, such as PVC injection pipe prices, which unifies the product specifications size and quality indicators PVC molded fittings supply, and product interchangeability. This shows that the development of pvc water supply pipe has entered a mature stage, the product quality and construction quality are guaranteed PVC injection pipe material, thus ensuring the use of effects pvc water supply pipe. The water supply pipe pe international standard (ISO4427) was officially released until 1996. Our reference in 1999 to write the national standard ISO4427 GB / T13663, and promulgated in 2000, but has standard pe pipe fittings, engineering and other technical specifications continues perfected. This shows that domestic pe pipe quality has not been stable, pipe fittings supporting not perfect, and therefore can not ensure the production, construction quality. Our PVC resin consumption is mainly concentrated in two areas south and east, Guangdong, Zhejiang, Fujian, Shandong and Jiangsu provinces, the total consumption of the country's total consumption accounts for about 70. 0% where the market demand in Guangdong and Fujian most, but production capacity, higher imports of polyvinyl chloride resin proportion; Jiangsu, Shandong and Zhejiang provinces PVC resin processing industry is relatively developed provinces accounted for consumption total domestic consumption of 34. 0%; North China sales balance. In the future, along with the construction of the Midwest as well as large-scale development efforts to strengthen infrastructure, consumption of PVC resin Midwest will gradually increase.
