What is PPR?
PPR means polypropylene random copolymer, a thermoplastic consisting of chains of carbon and hydrogen. The“R” refers to the random blend of long and short hydrocarbon chains that provide both rigidity and flexibility, resulting in a material with strong structural properties that can absorb impact and deflection.
Polypropylene random copolymer (PPR) pipes and fittings are used for plumbing inmechanical and industrial applications around the world. Pipes made from PPR are lightweight, non-corrosive, non-rusting and non-scaling. They are permanently leak-free by hot-fusion connections and leak-free joints.
What is SDR?
Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall.
What is the thermal expansion coefficient of RIIFO PPR Pipe?
The thermal expansion for RIIFO PPR Pipe is approximately 0.16(mm/mK).
What sizes of RIIFO PPR Pipe are available?
Available with nominal outer diameters of 20, 25, 32, 40, 50, 63, 75, 90, 110, 160.
Does RIIFO PPR pipe affect the quality of drinking water?
Approved by NSF/KTW certification test,RIIFO PPR pipe isnon-toxic, odorless,harmless,andnot easy to breed bacteria.
What is the purpose of the color stripes on the pipe?
The color stripes are used to distinguish the working conditions of pipelines. Red represents hot water pipelines, and blue represents cold water pipelines.
What connection method does RIIFO PPR Pipe use and what are the requirements?
According to the material properties of polypropylene random copolymer and the method of connection by out - fusion welding, RIIFO PPR Pipe uses heating to make the PPR joint reach the melting point and melt, and then uses the socket method to fuse the pipe and the pipe fittings together.
