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
50%, 100%, 150%, 200%... Recently, the domestic raw material prices have continued to rise, causing many downstream companies to complain, and from the perspective of transmission, due to the continuous crazy price increase in the upstream, the transmission speed of the price increase tide It is also very fast, beyond the imagination of many people. According to Coatings Purchasing Network, as
After experiencing a sharp increase in mid-to-late December 2020, domestic steel prices began to fall in January this year, and the prices of various steel products fell by 200 yuan/ton to 600 yuan/ton. Although the current steel price has corrected somewhat, steel mills and steel traders are optimistic about the trend of steel prices after the Spring Festival and throughout the year. Currently, t
