HDPE jacket pipe is a thermoplastic engineering plastic polymerized from ethylene monomers under a catalyst, with a viscometric molecular weight greater than 1.5 million. This product has very good overall properties: wear resistance, low-temperature resistance, corrosion resistance, self-lubrication, and impact resistance that are among the best of all plastics; wear resistance superior to PTFE, nylon, POM, carbon steel, brass, and other materials; and it can work long-term from -269℃—+80℃. It is known as a “remarkable” engineering plastic. Let us take a closer look below. Black-Jacketed Direct-Buried LSAW Pipe introduction.
Polyethylene products have extremely high wear resistance, impact resistance, excellent internal-pressure strength, environmental stress-crack resistance, good self-lubrication, anti-adhesion, unique low-temperature resistance, excellent chemical stability, and other superior properties, and are widely used in urban heating, electric power, petroleum, textiles, papermaking, food, chemicals, machinery, electrical, and other industries. Since these plastic products appeared in the 1970s, they have been favored by users for their good performance, but their special processing difficulty limited their development and application. It was not until the late 1970s that research institutions and major companies in developed countries such as the UK, Germany, and the United States began to industrialize them, thus opening the prelude to large-scale application of ultra-high-molecular-weight polyethylene (UHMWPE). As countries continuously increased research efforts, forming methods such as sintering, ram extrusion, screw extrusion, and injection molding were gradually developed, laying the foundation for large-scale application of UHMWPE.
Detailed Advantages of Black-Jacketed PU Insulated Steel Pipe
HDPE is known as a remarkable plastic. Summary of its combined advantages: excellent wear resistance—wear strength about 7 times that of carbon steel; low coefficient of friction and good non-stick properties; high impact strength, especially outstanding low-temperature impact resistance, among the best of known plastics; excellent chemical stability—except for a very few solvents, common inorganic and organic acids, alkalis, salts, and organic solvents do not corrode this material. Ultra-high-molecular-weight polyethylene is chemically similar to PTFE and is an inert material. Excellent aging resistance: under natural sunlight, the aging life of HDPE is 50 years.
