PPR is the abbreviation of tripropylene polyethylene, also known as random copolymer polypropylene pipe. It adopts heat welding method, has special welding and cutting tools, and has high plasticity. The price is also very economical. With the addition of thermal insulation layer, the thermal insulation performance is better, and the pipe wall is also very smooth. It is generally used in embedded walls, or in pre-embedded pipes in deep wells. PPR pipe is moderate in price, stable in performance, heat-resisting, heat-insulating, corrosion-resistant, smooth inner wall without scaling, safe and reliable in the pipeline system, impermeable, and has a service life of up to long-term durability according to standards. There are many colors of PPR water pipes, green, gray, white, and black can be done. PPR water pipes are divided into hot and cold water pipes. The most intuitive way to distinguish them is that there is a red line in the middle of the outer wall of the water pipe, which is a hot water pipe.
