Domestic plastic pipe quality problems cause concern

It is well known that the long-term use of steel pipes used in the past will lead to rusting of the inner wall of the pipe and the occurrence of dirt causing bacterial growth, which has a great negative impact on human health. However, with the development of science and technology, the emergence of green plastic pipes has avoided this defect very well, and the plastic pipe can achieve a good energy-saving and water-saving effect and become a brand-new green industry.

Recently, Qingtian County Market Supervision Administration commissioned Wenzhou Quality and Technology Supervision and Inspection Institute to carry out special spot checks on the quality of household building materials and plastic pipe products in circulation. This time, a total of 20 batches of goods (including pvc-U drain pipe, PP-R pipe and PVC-U flame-retardant electrical bushing) were collected. There were 19 batches that failed the inspection. The qualified rate of plastic pipe products was only sampled. It is 5%. The unqualified items of PVC-U drain pipe are mainly concentrated on the tensile yield strength of the drain pipe that does not meet the requirements. The unqualified items of PP-R pipe are mainly concentrated in the “opaque” and “size” items that are not up to standard. The unqualified items of PVC-U flame-retardant electrical bushings mainly focus on the "compressive performance" and "minimum wall thickness" indicators are not up to standard. In response to the above unqualified commodities, Qingtian County Market Supervision Administration has carried out the investigation and investigation work according to law.

Cao Yu, executive vice chairman of China Plastics Association, said that China's economic development has entered a new normal, and China's plastics processing industry, including plastic pipes, must ensure the quality of products, adhere to innovation, and lead the development of the whole industry to the middle and high-end level. Thereby achieving the goal of surpassing the level of developed countries in 50 years.
