PP-R, a random copolymer polypropylene, is a new type of water pipe material commonly used in developed countries. It uses homogeneous welding technology in hot and cold water transportation projects, and its comprehensive technical performance and economic indicators are far superior to other similar products. In particular, its excellent hygienic performance can achieve extremely high hygiene and environmental protection requirements from production to waste recycling.
The products have the advantages of heat resistance, pressure resistance, heat preservation and energy saving, long service life and economy, and will gradually replace other existing water pipes and become the leading products.
PVC pipe is a plastic pipe made of polyvinyl chloride (PVC) resin and containing no plasticizer.
PE is polyethylene. Under normal circumstances, the use temperature does not exceed 45 degrees, and the lower limit temperature requirements are different in the gas and water supply fields.
At present, domestic PE pipelines are mainly used in gas transmission and distribution, municipal water supply, and also in indoor cold water transportation, sewage, irrigation, aquaculture, etc. The prospects are very good. It should be said that PE pipes are the leading figures in pipeline materials.
