Polyethylene (PE) winding structure wall tube is made of high-density polyethylene (HDPE) as raw material, adding 1.5-2% color masterbatch, through two single screw extruders (one is machine square tube, one is Extruded PE adhesive) extruded onto the inner mold, wound the square tube onto the inner mold (the inner mold is rotating), polyethylene (PE) wound structural wall tube between two square t
The implementation standard is: "Underground Polyethylene (PE) Structure Wall Pipeline System" Part 2: "Polyethylene Wrapped Structure Wall Pipe" (GB / T19472.2-2004). HDPE hollow wall winding pipe is a kind of structural wall pipe made of high-density polyethylene (HDPE) as a raw material and adopting hot winding forming process, which complies with the national standard "Underground Polyethylen
With the increase in market demand, hdpe double-wall corrugated pipes continue to develop and expand, and the application field is also expanding. What should be done when installing and using double-wall corrugated pipes? Let's explain in detail below, the construction technology of double-wall corrugated pipe to prevent us from having to start during construction.
How to connect double-wall corrugated pipe? Many people are asking such a question. For people in the industry, this is a simple question; for people outside the industry, few people ask this professional question (although the method of asking is very unprofessional, it should be the connection of double-wall bellows What are the ways), then this question should be raised by the staff who have ju
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
What are the equipment classification and advantages of HDPE double-wall corrugated pipe production line? 1. Classification of double-wall corrugated pipe production line equipment 1. According to the material produced: it can be divided into three categories: HDPE, PP, PVC, etc. 2. According to the structure and shape of the equipment: it can be divided into three types: horizontal, vertic
