Hdpe Pipe Manufacturer in China
Hdpe pipe is a plastic pipe made of high-density polyethylene (HDPE) resin as the main raw material, through extrusion molding or other processing techniques.
HUALIN Hdpe pipes are usually made by extrusion molding. After the high-density polyethylene resin is heated and melted, it is extruded into pipes through an extruder. During the production process, appropriate additives such as antioxidants, ultraviolet absorbers, etc. can be added according to different usage requirements to improve the performance of the pipe.

Key Features of HUALIN Hdpe Pipe
HDPE pipe is white powder or granular, with a density of 0.940~0.976 g/cm³, a crystallinity of 80%~90%, a softening point of 125~135℃, an operating temperature of up to 100℃, and a short-term upper temperature limit of 120~160℃. Its chemical properties are resistant to acid, alkali and salt corrosion, insoluble in organic solvents at room temperature, but sensitive to strong oxidizing media14; long-term use may lead to performance degradation due to thermal oxidation, and antioxidants need to be added to improve; HDPE pipe has high rigidity, toughness and creep resistance, and its wear resistance and environmental stress cracking resistance are better than low-density polyethylene

HUALIN Hdpe Pipe Applications Explored
Our Hdpe pipe are widely used in various applications to solve the problems of corrosion and short life of traditional pipes. In the industrial field, they can withstand corrosive fluids such as strong acids, alkalis, and salts (such as chemical wastewater treatment), and replace metal pipes to reduce the risk of leakage. In power and communications, they are used for direct burial or trenchless laying (such as highway power channels), resist soil erosion and chemical corrosion, and their flexibility supports wiring in complex terrains and protects communication lines. In water supply and drainage projects, they can be used for urban tap water supply pipes, drainage pipes, sewage treatment pipes, etc.
