Precautions for installation and construction of PE hollow winding pipe 1. The pipe mouth should be aligned, and the pipe connection process should be careful, and avoid contamination of the interface. It is not allowed to move the pipeline within 30 minutes after the pipeline is connected. 2. The heating time of the pipeline and shrinkage belt should be moderate, otherwise the connecti
Talking about the difference between hdpe spiral reinforced tube and hollow wall spiral tube 1. Carat tube (HDPE winding B tube) 1. What is carat? Carat tube (HDPE winding reinforced tube) is hdpe (high density polyethylene) structure wall hot state winding tube, HDPE winding structure wall tube, it is a new type of special-shaped structure wall pipe material, which is made by high dens
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. .
