Engineering PPR pipes and fittings have the same thermal expansion performance as anything else, which affects the high temperature resistance and service life of the pipeline. As a new type of water pipe material, PPR pipe has completely transformed its thermal expansion. PPR pipe produced by professional hot-melt mechanical operation is suitable for water supply engineering pipeline (cold and hot water engineering). It has high temperature resistance and high pressure resistance. The water pressure under normal temperature is 45 kg / cm2, and the non deformation temperature of the pipe is 112 degree .
PPR pipe adopts hot fusion technology in cold and hot water transmission engineering. Its comprehensive technical performance and economic index are better than PVC pipe and aluminum-plastic composite pipe. It is one of the leading products of water supply pipeline in European and American developed countries. Under the condition of long-term continuous working water pressure and water temperature up to 95 degree , the service life can be up to 50 years. It is valued by countries all over the world for its excellent health, environmental protection performance, heat resistance, pressure resistance, corrosion resistance, flexibility and earthquake resistance,
The elastic modulus of PPR pipeline is the standard, and the index of deformation resistance is higher than that of other pipes, so it is more suitable for hot water pipeline. Carbon structure composite PPR pipe fittings are also the representative of high temperature resistant pipes.
The low thermal conductivity of random copolymerized polypropylene pipe (PPR pipe) in PPR pipe industry makes it a good pipe against high temperature. Generally, its perfect performance can be realized without additional thermal insulation materials.
