 Supply PPR pipe, PERT to warm the pipe, PPR pipe production, Matilda Pipe PPR-use features 


 PP-R pipe in addition to a general plastic pipe, light weight, corrosion resistant, does not scale, long service life characteristics, but also has the following main features: 



 1, non-toxic, health. Of PP-R materials elements only carbon, hydrogen, no harmful toxic elements exist that health can not only used for hot and cold water pipes, can also be used for pure drinking water systems. 


 2, energy-saving insulation. PP-R pipe thermal conductivity 0.21w/mk, and the steel is only 1/200. 


 3, good heat resistance. PP-R pipe, Vicat softening point of 131.5 ℃. The maximum operating temperature up to 95 ° C, to meet the building to the use of hot water systems in the drainage specification requirements. 


 4, long service life. PP-R pipe operating temperature of 70 ° C, working pressure (PN) 1.OMPa under the conditions of life of up to 50 years; room temperature (20 ° C) the service life of up to 100 years. 


 5, easy installation, connection *. PP-R has good welding properties, pipe, pipe fittings may be hot melt and fused connection, easy installation, the connector * the strength of its joints is greater than the strength of the pipe itself. 


 6, the material recyclable. PP-R waste by cleaning, recycling broken pipe, pipe production. The amount of recycled materials does not exceed 10% of the total, does not affect product quality. 








 PPR pipe - The main purpose 


 1, the building hot and cold water systems, including central heating systems; 


 2, the heating system within the building, including flooring, siding, and radiant heating system; 


 3 can be directly purified water for drinking water supply system; 


 4, the central (concentration) air conditioning systems; 


 5, delivery or discharge of chemical media, such as industrial piping systems. 





 The selection of the PP-R 


 1, note that the pipeline overall factor C (safety factor), to determine: 



 General situations, and long-term continuous temperature <70 ° C, optional C = 1.25; on important occasions, and long-term continuous use temperature ≥ 70 ° C, and there may be a long time at a higher temperature run, optional C = 1.5; 


 For cold water (≤ 40 ° C) system, the choice of the P.N1.0 ~ 1.6MPa pipe, pipe fittings; 
 Used for hot water system selection ≥ PN2.0MPa pipe, pipe fittings. 


 3, after considering the above three principles, the SDR of the pipe should not be greater than the pipe SDR pipe wall thickness shall not be less than the same size pipe wall thickness. 


 PPR pipe performance 


 Barrier properties: PP copolymers and homopolymers have very low water vapor permeability (0.5 g / ml / 100 square inches / 24 hours). These properties can be improved through targeted. Stretch blow molding of polypropylene bottle has resistance to water vapor permeation performance improvement to 0.3, the oxygen permeability to 2500. 


 Electrical properties: Generally, polypropylene has good electrical properties, including: high dielectric strength, low dielectric constant and low loss factor; However, the power application generally opt for the homopolymer.
