Plastic Manhole _ ho _ plastic pipe industry manholes processing provided by the ho-pipe industry. Plastic manholes, ho-tube, plastic manholes specifications Zhengzhou Haotong Pipe Co., Ltd. (www.zzhtgy.com) 2014 upgrade been newly launched Zhengzhou Haotong Pipe Co., Ltd., is a large Central Plains municipal sewer HDPE double One wall corrugated pipe production enterprises corrugated pipe application aspects in life, or in China in recent years to do. In telecommunications, railways, air conditioning ducts in the central system, the sewage treatment system, double-wall corrugated pipe pipe in all walks of life. But in Europe the plastic inspection wells, the amount of double-wall corrugated pipe is still very large. According to the European 97-year investigation, the total amount of 2.264 million tons of plastic pipe used for drainage and sewerage is 1.274 million tons, accounting for 56.2%, this is because the country needs to build a modern, large sewage pipes throughout rural and urban drainage systems. In terms of pipeline use because technically more advanced European countries prefer the double-wall corrugated pipe. Its light texture, cold resistant, more suitable for the use of sewage treatment systems. Zhengzhou Haotong Plastic Pipe Industry Co. Manhole parameters, the Central Plains municipal drains relatively large double-wall corrugated HDPE pipe manufacturer of pvc double wall corrugated polyethylene pipe is the inner wall of the main raw materials for the production of smooth, corrugated outer wall, Special pipe outer wall hollow. The appearance of plastic pipe inspection wells processing, compression resistance, water resistance is small, acid corrosion. Easy installation and transportation, has significant advantages of energy saving, water saving.
