Description

PP pipe, also known as polypropylene tube, has the advantages of energy-saving and material saving, environmental protection, lightweight and high strength, corrosion resistance, a smooth inner wall without scaling, simple construction and maintenance, and long service life. It is widely used in chemical, electronic and electrical, metallurgy, electroplating, oxidation, pickling, textile, food, machinery manufacturing, and other industries. PP pipes are made of polypropylene through an extrusion and injection molding to become pipe fittings.

1. Extremely high wear resistance

The ultra-high molecular weight polypropylene pipe is as high as 2 million or more, and the wear index is the smallest, which makes it have extremely high resistance to sliding friction. The wear resistance is 6.6 times higher than general alloy steel and 6 times nylon, which greatly improves the service life of the pipeline.

2. Very high impact resistance

In the existing engineering plastics, the impact toughness value of ultra-high molecular weight pipes is relatively high. Many materials will crack, break, break or surface stress fatigue during repeated impacts. This product is in accordance with QB/T 1929-2006 Section 6/7 and GB/T 14152-2001 standards, after repeated drop hammer impact tests, it can achieve no damage. Therefore, PP pipes can withstand extreme environments such as external force shocks and pressure fluctuations.

3. Corrosion resistance

Ultra-high molecular weight polypropylene pipe is a saturated molecular group structure, so its chemical stability is extremely high. This product can withstand the corrosion of strong chemical substances. Except for some strong acids that have slight corrosion at high temperatures, it is not corroded in other lye and acid solutions. It can be used in concentrated hydrochloric acid with a concentration of less than 80%. It is quite stable in sulfuric acid with a concentration of less than 75% and nitric acid with a concentration of less than 20% under a 60 C°environment.

The main material of PP pipe is polypropylene, which is another excellent resin developed after nylon. PP pipe manufacturers make full use of these advantages of polypropylene to produce PP pipes with certain strength and toughness. The advantage of this kind of pipeline is that it can reduce some weight problems in the construction process, reduce the construction pressure, and have a good appearance and use advantages.
