First, PPR pipe production process
Automatic feeding - Heating extrusion - Vacuum sizing - Cooling - Secondary watering - Product printing - Traction - Length cutting - Inspection - Packaging - Storage
Second, PPR tube features:
1, health, non-toxic: This product is a green building materials, can be used for pure water, drinking water piping systems.
2, corrosion-resistant, non-scaling: can be avoided due to pipeline corrosion caused by tubs, bathtubs, macular rust worry, can be caused by pipe corrosion and scaling caused
3, high temperature, high pressure: pipe water temperature up to 95 ℃.
4, energy-saving insulation: thermal conductivity is only one-hundredth of the metal pipe, for hot water pipe insulation energy saving excellent.
5, light weight: the proportion of only one-seventh of the metal tube.
6, beautiful appearance: the product inside and outside the wall smooth, fluid resistance, soft color, handsome in appearance.
7, easy installation *: hot melt connection, a few seconds to complete, safe *.
8, long service life: the provisions of the long-term continuous working pressure, the use of life expectancy of up to 50 years.
Third, PPR tube applications:
1, residential hot and cold water piping system;
2, industrial water and chemical transport, emissions;
3, pure water, drinking water pipes;
4, beverage, drug delivery system;
5, compressed air tube;
6, other industrial and agricultural pipe.
Fourth, PPR strengths and safety risks
PPR pipe (Poly Propylene Random), that is, random copolymerization polypropylene pipe, is a new type of pipe material used in today's booming countries. PP-R pipeline in Europe has more than 10 years of experience, because of its excellent features, its market share in recent years, ahead of other plastic pipe materials, the current domestic construction of cold and hot water and heating are simply used PVC-C, PE-X, plastic pipe and PP-R pipe, and gradually to the PP-R pipe transition. PP-R tube is one of the hot spots when it is produced and used. PP-R pipe is gradually recognized by the Chinese plumbing industry, PP-R pipe except with ordinary plastic pipe light weight, corrosion resistance, high strength, non-scaling, long life and other common advantages, but also has a clean and non-toxic , Better low temperature shock resistance, long time heat and pressure resistance, superior Paul Ping and energy saving features, is a real green building materials products, but also with the system convergence and convenience of the device, the pipe fittings and strong, and is immutable Cohesion and other characteristics.
In addition, PP-R pipe has excellent function and price ratio. At present, there are more than 300 PP-R pipe production plants in our country. There are many kinds of PP-R pipe in the existing building materials market. Because of various reasons, the quality of PP-R pipe More prominent, resulting in the strength and characteristics of PP-R pipe can not be full performance, affecting the use of pipeline engineering function, but also to respond to the quality of the project laid a safe hidden trouble.
