PP Duct Mechanical Properties The crystallinity of PP ducts is high and the structure is regular, which endows them with excellent mechanical properties. However, at room temperature and low temperatures, the impact strength is relatively poor due to the high regularity of its molecular structure. The outstanding feature of PP pipes is their resistance to bending fatigue, commonly known as "hundred-fold rubber." □ Made from specially formulated co-polymer grade PP raw materials for general-purpose pressure water transport and drinking water conveyance. □ The sanitary performance of drinking water pipes complies with GB/T17219 standards. Outstanding Quality of Polypropylene PP Pipes ◇ Long service life ----- Under rated temperature and pressure conditions, PP pipelines can be safely used for over 50 years. ◇ Excellent corrosion resistance ----- They can withstand the corrosion of most chemicals and can endure high concentrations of acids and bases with a pH range from 1 to 14. ◇ Superior wear resistance ----- When conveying mineral slurry, PP pipes have over four times the wear resistance of steel pipes. ◇ Good sanitary performance ----- The molecular structure of PP pipes consists of carbon and hydrogen elements, making them non-toxic and odorless, ensuring reliable sanitary properties. ◇ Heat insulation and energy-saving ----- PP pipes have a high service temperature of around 95 degrees Celsius, and their thermal conductivity is only 1/200 that of steel pipes, providing good insulation performance. ◇ Reliable connection performance ----- The strength of the heat fusion joints of PP pipes exceeds that of the pipe material itself, ensuring that joints do not break due to soil movement or load effects. ◇ Good construction performance ----- The pipes are lightweight, the welding process is simple, and construction is convenient, leading to lower overall project costs.
