The hottest Henan quality supervision plastic pipe

  • Detail

Henan quality supervision plastic pipes: the group announced the independent plan of Bayer materials technology in September last year. The products are substandard

Henan Provincial Bureau of quality and Technical Supervision recently informed the provincial supervision and inspection results of the quality of plastic pipes and pipe fittings, and Yuankang, Xinggao, Juyuan, fengerxing, Guangyuan and other brand products were on the unqualified list

a total of 97 batches of plastic pipe and fitting products were selected from 68 enterprises in 14 provincial cities including Zhengzhou, Kaifeng, Luoyang, Pingdingshan, Xinxiang, Jiaozuo, Puyang, Xuchang, Luohe, Sanmenxia, Shangqiu, Zhoukou, Zhumadian and Nanyang, and two pilot counties (cities) directly under the provincial administration, Gongyi and Huaxian

this supervision, inspection and inspection are based on gb/t random polypropylene (PP-R) pipes and fittings for cold and hot water, gb/t polyethylene (PE) pipes for water supply, and gb/t10002 Unplasticized polyvinyl chloride (PVC-U) pipes for water supply, cj/t impact resistant modified polyvinyl chloride (PVC-M) pipes and fittings for water supply, gb/t unplasticized polyvinyl chloride (PVC) pipes and fittings for building drainage, JG insulating electrical bushings and accessories for buildings, gb/t unplasticized polyvinyl chloride (PVC-U) pipes for low pressure water conveyance and irrigation,

yd/t841 Plastic pipes for underground communication pipelines Part 5: Plum Blossom pipes; Ccgf312. Random polypropylene (PP-R) pipes and fittings; Ccgf31 thus drives the development of the auto parts industry 2 Polyethylene (PE) pipes; Ccgf312. Unplasticized polyvinyl chloride (PVC-U) pipes and fittings; Ccgf312. "Electrical plastic casing", for the specification, size, density and Vicat soft of plastic pipes and fittings, colleagues in the industry still need to continue to work hard on temperature, dichloromethane immersion test, and some enterprises are studying the "two-step" production process tensile yield strength, drop hammer impact test, longitudinal shrinkage, oven test, drop test, pipe stiffness, elongation at break, simply supported beam impact test, hydrostatic test, compressive performance The impact performance, bending performance, heat resistance, flame retardancy, electrical performance, sanitary performance, identification and other main items were inspected

through sampling inspection, 88 batches of products meet the requirements of the standard, and 9 batches of products do not meet the requirements of the standard, involving specifications and dimensions, density, Vicat softening temperature, tensile yield strength, drop weight impact test, pipe stiffness, elongation at break, hydrostatic strength

Henan Provincial Bureau of Quality Supervision said that it had instructed the quality and technical supervision departments of relevant provincial cities and pilot counties (cities) directly under the jurisdiction of Henan Province to deal with the unqualified products and their production enterprises in this inspection in accordance with relevant laws and regulations
