The first plastics factory in Zhengzhou invested more than 20 million yuan to introduce a 90-ton plastic 110-400 mm diameter double-wall corrugated pipe production line with the 90s level from the Unikir company in Germany. The current test run was successful. The plastic double-wall corrugated pipe produced has reached and surpassed the German DINI6961 standard in physical and chemical performance indicators. At this point, the first plastic factory in Zhengzhou City has become the first manufacturer of plastic single- and double-wall corrugated pipes in Henan Province with large scale, complete varieties, multiple types, bright colors, and high output from 9 to 400 mm. As early as 1984, the first plastics factory in Zhengzhou introduced 200 annual output from West Germany.
