PP-HM corrugated pipe is a pressure-free buried wall system for drainage and sewage, that is, pipes and fittings with smooth inner surface and irregular outer surface. This kind of pipe system is based on high-strength modified PP-HM resin. Material, adding special modified functional masterbatch, on the premise of ensuring stable product quality, comprehensively improve the impact, rigidity an

Plastic bellows was first developed in the 1950s, and has developed by leaps and bounds in the last 20 years. The plastic bellows that have been developed and applied can be divided into "HDPE bellows", "UPVC bellows" and "PP bellows" according to the materials used to produce plastic bellows. .

Rapid urbanization and industrialization have increased the threat of sewage to the environment; solid waste pollution, landfills, industrial wastewater, and sewer leaks can all pollute groundwater, and the related cleaning work requires a long time and expensive costs. The traditional underground drainage pipes mainly include concrete, clay and plastic (PE, PVC) and other pipes, but the tradition

Regardless of the dynasty, water conservancy projects are important for urban construction. In ancient times, people in our country basically lived on agriculture and became self-sufficient. If imperfect water conservancy projects would lead to flooding, people would live a hard life. Now is the process of urbanization. If the water conservancy project is not done well, it may lead to the destruct

HDPE double-wall, hollow, spiral three corrugated pipe introduction There are many types of HDPE corrugated pipe, such as HDPE double-wall corrugated pipe, hollow wall pipes, HDPE spiral corrugated pipe, etc. These types of corrugated pipe are different due to different pipe specifications and different pipe wall structures. I have summarized these three corrugated pipe The difference is to hel

Comprehensive and profound understanding of HDPE double-wall corrugated pipe HDPE double-wall corrugated pipe, referred to as PE corrugated pipe, was first developed successfully in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. It has been very mature in production technology and use techn
