PVC water pipe
PVC water pipes are made of polyvinyl chloride resin as the main raw material, with additives. They are specifically used for drinking water and domestic water supply systems. They have advantages such as being lightweight and high-strength, corrosion-resistant, non-scaling, and having low water flow resistance. They are easy to install and have low cost. The pipe material's hygiene performance meets standards, has a long service life, and can effectively ensure water quality safety. It is an economical and practical pipe material choice for urban and rural water supply projects.
