Factory Hot Sale Green Polypropylene Copolymer Fittings High Pressure Spray Hose Tube PPR Pipe Fitting

----------------------------------------

Basic Info.

PPR (polypropylene random) is the abbreviation of polypropylene random copolymer, which can be processed into pipes or injection molded into pipe fittings. The basic structure of its polymer chain is modified by adding different kinds of monomer molecules. It can be widely used in the production of pipes, sheets, daily necessities, packaging materials, components of household appliances and various films.

Advantage

1. The production energy consumption of energy-saving PP-R pipe is only 20% of that of steel pipe, and its thermal conductivity is low [0.2W/(mK)], which is only 1/200 of that of steel pipe. It is used in hot water systems to greatly reduce heat. loss.

2. Corrosion-resistant, non-scaling, hygienic, and non-toxic The use of PP-R pipes can eliminate the "secondary pollution" of water quality caused by scaling and rusting of the inner wall caused by the use of galvanized steel pipes. Because PP-R is simple in composition, and its basic components are carbon and hydrogen, it conforms to food hygiene regulations, is non-toxic, and is more suitable for drinking water transportation.

3. Heat resistance, pressure resistance and long service life The long-term use temperature of PP-R pipe can reach 95℃, and the short-term use temperature can reach 120℃. Under the condition of using temperature of 70℃ and working pressure of 1.2MPa, it can be used continuously for a long time, and its service life can reach more than 50 years.

4. The density of PP-R pipe is only 1/8 of that of metal pipe, and the pressure resistance test strength is as high as 5MPa, and it has good toughness and impact resistance. Due to the smooth inner wall, no rust and no scaling, the fluid resistance is small. The main technical indicators of PP-R pipe are as follows: density 0.9g/cm3 elastic modulus (20℃) 800MPa thermal expansion coefficient 1.8×10-4/K thermal conductivity 0.2W/(mK) longitudinal shrinkage rate 2% impact Test breakage rate ≤ 10% hydraulic test short-term 1h, ring stress 16MPa no leakage long-term 95 ℃, 1000h, ring stress 3.5MPa no leakage Table 1 shows the performance comparison of several materials.
