A Chinese pipe company – HNHC has purchased a vertical air-cooling corrugated pipe extrusion line from another company. As a result of increasing market competition and launching new generation of corrugated pipe lines, HNHC's profit has been declined year by year. On the other hand, the increased demand for corrugated pipes in domestic market in the past two decades attracts more and more manufacturers to enter this industry. As it turns out, the overall price level decreases for corrugated pipe production which generates less profit for pipe manufacturers. With this reason, HNHC came to us after 9 years since their first purchase and asked to improve their production efficiency.
In 2009, ZhongyunTech has manufactured and provided this customer with the China's first pressurized water cooling corrugated pipe extrusion line. Due to its advantages of fast production speed, low energy consumption and easy mould changeover, this innovative corrugated pipe extrusion line has become the mainstream in China over the past decade.
After using the water-cooling corrugated pipe extrusion line, HNHC has yielded their profit significantly. Since then, HNHC's parent company has ordered 8 sets of corrugated pipe extrusion lines from us.
