Teach you how to identify the true and false PPR tube!

PP-R (polypropylene random) tube is also called three-type polypropylene tube and also called the random copolymer polypropylene tube or PPR tube, with energy-saving materials, environmental protection, light and high strength, corrosion resistance, smooth internal wall scaling, construction and maintenance of simple, long service life, and other advantages, widely used in building water supply and drainage, Urban and rural water supply and drainage, urban gas, electricity and cable sheath, industrial fluid transport, agricultural irrigation and other construction, municipal, industrial and agricultural fields. PP-R tube with random copolymerization of polypropylene through extrusion into pipe, injection into the pipe.


The true pp-R pipe should conform to the standard gb/t18742-2002<< plastic piping system for hot and cold water--pp Part II tubing > > Pipe fitting should conform to standard gb/t18742-2002 << hot and cold water plastic piping system--pp Third part The performance of Pseudo-PP-R pipes and pipe fittings cannot pass the above standard. It should be noted that the service life of Pseudo-PP-R pipe is only 1-5 years, and the real life of PP-R tube is more than 50 years.


How does the PPR Tube identify?


PPR pipes are widely used in industrial and residential buildings, sanitary drinking water supply and hot water heating. PPR Pipes are divided into 2 kinds of hot and cold water pipes. Cold water tube wall thin, hot water pipe wall thickness, so in the resistance to fracture of the hot water pipe performance is much better, the price of hot water pipe than cold water more expensive. Many manufacturers for the sake of insurance, the construction process does not separate hot and cold water pipe cracking, improve safety factor.


1. Good soft PPR pipe, the pipe is not easy to squeeze and deformation, even if the deformation does not rupture, and greatly reduce the use of joints.


2. Corrosion-resistant waterproof scaling pr-r tubing, pipe fittings of the chemical properties of water can be resistant to corrosion of chemical elements, while smooth interior surface can avoid the formation of scale


3. High temperature, high pressure PR pipe, pipe fittings under normal temperature under water pressure of 45 kilograms/square centimeters, pipe deformation temperature of 112 degrees Celsius


4. Long life PPR Pipe, Pipe fittings anti-aging strong, the normal role of the mission reached more than 50 years.

5. Simple and rapid construction of PPR pipe, the flexibility of the pipe to make the construction become very fast, and easy to connect (with hot-dissolving machine socket connection), safe and reliable.


6. Economic benefits as a result of simple construction, there is no contradiction between and the other projects and impact, shorten the construction period, cost savings than copper pipe 60%, with superior economic.


Therefore, consumers should be cautious when buying, must choose the right, large manufacturers, quality assurance of the pipe, in addition to the installation, there are some points of attention, may wish to listen to expert advice.
