Introduction of PE hollow wall winding pipe equipment PE hollow wall winding pipe equipment is a new product that replaces the metal protective spring used for maintenance of the rapid-entry hose. The surrounding tube is generally made of nylon material or polypropylene material. Corresponding to the traditional metal spring protection product, the surrounding tube has good wear resistance, ant
Carat pipe, also known as HDPE winding structure wall pipe, is made of high-density polyethylene resin as the main raw material, adopts thermal winding molding process, and uses polypropylene (PP) single-wall corrugated pipe as the supporting structure to have high resistance to external pressure. Capable of special structure wall pipe. The product has a smooth inner surface and a special-shaped r
Carat tube is a high-density polyethylene structural wall thermally wound tube, HDPE wound structural wall tube, it is a new type of special-shaped structural wall tube, made by high-density polyethylene thermal winding molding process. Carat pipe products are mainly made of high-density polyethylene resin (HDPE) as raw materials, PP or PE corrugated pipes are used as auxiliary support pipes, and
The large-diameter HDPE plastic-steel winding pipe is made of steel-plastic composite special-shaped belt material through spiral winding welding (extrusion welding on the lap surface), its inner wall is smooth and flat, and the specification is dn200-dn3000mm. This kind of pipe has the advantages of corrosion resistance, light weight, simple installation, large circulation, long life (50 years),
The main steps of the hot pressing process are as follows: Raw material preparation → mixing and heating → extrusion molding → cooling → demoulding The main process is extrusion molding using hot-melt raw materials of thermoplastics to be extruded and then cooled for molding. The main equipment is an extruder and a die. The detailed process flow is as follows: Plastic sheet production process,
The safe service life of HDPE double-wall corrugated pipe is more than 50 years. This has not only been proved by international standards and the new international, but also by advanced countries. Cement management theory has a service life of 20 years, but it is a silicate type, which is corroded by acid and alkali for a long time, and its service life is greatly reduced. There are instances of
Unique structure, high degree of automation, convenient operation, stable and reliable continuous production. The pipes produced by the PE water supply pipe production line have moderate rigidity, strength, good flexibility, creep resistance, environmental stress crack resistance and good thermal welding performance, and have become the first choice for urban gas pipelines and outdoor water suppl
With the increasing awareness of environmental protection, taking the path of healthy and ecological sustainable development has become the best choice for the packaging industry. As the most widely used plastic packaging material, degradability has become a trend. According to the different principles, degradable plastic materials are divided into the following three categories: biodegradable
